Evaluation of characteristics of periodontal probes

Aim: This study aimed to evaluate the millimeter distances and active tip diameters of different periodontal probes. Methods: Two types of periodontal probes were analyzed (North Carolina (15-UNC) and PCP-12). Two manufacturers were selected for each probe type. Digital images of the probes were obtained and the distances were measured using a software program. The diameter of the active tip was measured using a digital caliper. Both variables were measured by two trained and calibrated examiners. The data were analyzed using the Bland-Altman method and two-way ANOVA with Tukey's post-hoc test. Statistical significance was set at p<0.05. Results: A comparison of measurements between the 15UNC and PCP-12 probes showed a significant difference in all millimeter markings. The 15-UNC probe showed differences between the 3 and 12 mm markings. The PCP-12 probe only showed differences between the marks at the 12 mm mark. The 15-UNC probe had a similar active tip diameter between the two manufacturers. The PCP-12 probe showed a significant difference between the two manufacturers. Both types of probes had similar active tip diameters when compared by the two manufacturers. Conclusion: There was no standardization in relation to millimeter marks and tip diameters of the two types of periodontal probes produced by the two different manufacturers. The probe types exhibited little variability

Evaluation of plaque index, gingival index and oral health-related quality of life in obese patients / Evaluación del índice de placa, índice gingival y calidad de vida relacionada con la salud bucal en pacientes obesos

Obesity is a chronic disease that may be related to caries, periodontitis, xerostomia, and dental erosion, as well as increasing morbidity and mortality. The aim of this study was to evaluate the plaque index (Silness & Löe, 1964), the gingival index (Löe & Silness, 1963), and the oral health-related quality of life (OHRQoL) in obese patients. The study included 45 extremely obese, 45 obese, and 45 normal-weight individuals between the ages of 18 and 58. The plaque index and gingival index of the individuals were determined by clinical examination by probing. In addition, the Oral Health Impact Profile-14 (OHIP-14) questionnaire was used for the OHRQoL. The IBM SPSS Statistic 22.0 software program was used for the statistical evaluation of the study data. The plaque index and gingival index values were statistically higher in obese compared to normal weight individuals (p0.05). There was no statistically significant difference between the OHIP-14 total scores of the groups (p>0.05). Increased apparent plaque index and gingival index values in obese patients may adversely affect periodontal health.

La obesidad es una enfermedad crónica que puede estar relacionada con caries, periodontitis, xerostomía y erosión dental, además de aumentar la morbimortalidad. El objetivo de este estudio fue evaluar el índice de placa, el índice gingival y la calidad de vida relacionada con la salud bucal (CVSB) en pacientes obesos. El estudio incluyó a 45 individuos extremadamente obesos, 45 obesos y 45 de peso normal entre las edades de 18 y 58 años. El índice de placa y el índice gingival de los individuos se determinaron mediante examen clínico y sondaje periodontal. Además, se utilizó el cuestionario Oral Health Impact Profile-14 (OHIP-14) para la evaluación CVSB. Se utilizó el programa informático IBM SPSS Statistic 22.0 para la evaluación estadística. Los valores del índice de placa y del índice gingival fueron estadísticamente más altos en obesos en comparación con los individuos de peso normal (p0,05). No hubo diferencia estadísticamente significativa entre las puntuaciones totales de OHIP-14 de los grupos (p>0,05). El aumento del índice de placa aparente y los valores del índice gingival en pacientes obesos pueden afectar negativamente la salud periodontal.

Relationship between Quality of Life and Oral Health Status of Patients with Chronic Liver Disease

ABSTRACT Objective: To investigate the relationship between the quality of life and work ability related to the oral health status of patients with chronic liver diseases. Material and Methods: The sample size contains all patients referred to the internal ward of Afzalipour and Bahonar hospitals due to chronic liver disease from 2019 to 2020. Patient selection was based on a simple census and a questionnaire that contained characteristics information of the patient, Work Ability Index questionnaire and SF-36 questionnaire were completed by the patients and some information was extracted from medical file. The SF-36 questionnaire assesses the quality of life in two general dimensions (physical health and mental health) with the physical function subscale. DMFT, Gingival index, and Periodontal disease index are used to evaluate the severity and extent of gingivitis and periodontitis. For data analysis, ANOVA, Spearman correlation coefficients were used and the significant level was p<0.05. Results: a total of 108 patients were examined. The mean age of participants was 41.2 ± 4.3 years. The DMFT index in patients was also reported as 22.6 ± 7.35. Also, 32.4% of people described their ability to do work as poor, 21.3% as good, and 7.4% as excellent. Patients with poor or moderate workability reported a higher index of DMFT. Among the participants, 61 and 21 patients had gingivitis and periodontitis, respectively. Mean results of total SF-36 indices were reported at a low level in patients with increased DMFT and gum diseases. Patients with poor or moderate workability had a higher index of DMFT. There was a significant relationship between these two variables (p=0.001). However, they were not significantly associated with periodontitis. Conclusion: There was a significant relationship between the SF-36 index, the ability to work and the type of liver disease.

Prevalence of Dental Caries in 5-Year-Old Children in a Northeast Brazilian Capital

ABSTRACT Objective: To evaluate the prevalence of dental caries in children aged five years in a Northeast Brazilian Capital (Fortaleza, CE) and its association with sociodemographic conditions, presence of malocclusion, and gingival bleeding. Material and Methods: This is a quantitative, descriptive, observational, and cross-sectional study carried out in a representative sample of 3,582 children aged five years in the city of Fortaleza-CE. Data was collected in public and private schools distributed in the city's Regional Health Coordination (CORES). Each of the six CORES worked with five field teams, participating in inter-examiner training and calibration with a final KAPPA coefficient of 0.87. Data were collected using a clinical form adapted from the SB Brasil 2010 questionnaire on sociodemographic conditions. The indices of dmft, need for treatment, malocclusion, and gingival bleeding were used for oral health conditions. The data were submitted to Pearson's Chi-square or Fisher's Exact tests, and the variables that show values of p<0.05 were submitted to a multinomial logistic regression model (forward stepwise model). Results: 57.1% of children were caries-free, and the mean dmft-d was 1.65 (1.65±2.65). CORES I and VI were the ones that presented the most significant association with caries attacks in all primary molars. The highest percentage of caries in the 2nd upper molar (60.6%), 1st lower molar (59%), and 2nd lower molar (58.8%) were found in children with normal occlusion. There was a significant association between gingival bleeding and caries in all molars and the need for treatment. Conclusion: These results allow us to observe that the prevalence of dental caries in 5-year-old children in Fortaleza is low, although with a tendency to increase.

Oral Condition of Adolescents who Participated in an Oral Health Program During the First Decade of Life

ABSTRACT Objective: To evaluate the oral health of adolescents who participated in an oral health preventive program during the first decade of life. Material and Methods: For the evaluation of dental caries and gingival condition, DMFT and Community Periodontal Index were used, both recommended by the World Health Organization. To verify the occurrence of dental fluorosis, the Dean index was used. Results: Data collection was obtained from 252 patients aged 12 to 16 years. The average DMFT index was 1.14; in relation to the gingival condition, the index of healthy gingival tissue prevailed and the average of this value was 84%, with code 0 being more registered in tooth 11, code 1, more frequently in teeth 16/17 and 36/37 and for last, code 2, in tooth 31 most frequently. Dean's index showed a percentage of 89% of patients without clinical signs of dental fluorosis. Conclusion: Adolescents participating in an oral health preventive program in the first decade of life exhibited very satisfactory results regarding the prevention of caries disease, healthy periodontal condition and reduced prevalence of dental fluorosis.

Effect of periodontal debridement plus systemic azithromycin in subjects with stage III periodontitis: a randomized controlled clinical trial / Efecto del desbridamiento periodontal más azitromicina sistémica en sujetos con periodontitis estadio III: un ensayo clínico controlado aleatorio

Aim: To evaluate the effect of the systemic administration of azi-thromycin (AZM) as an adjunct to non-surgical periodontal therapy (NSPT) on the clinical and microbiological variables of patients with periodontitis. Material and Methods: Eighteen volunteers received NSPT combined with placebo or AZM (500 mg/day) for 3 days (n=9/group). They were monitored clinically for probing pocket depth (PPD), clinical attachment level (CAL), O'Leary index (OI), bleeding on probing (BoP) at baseline and during the first, third and sixth month and microbiologically, at baseline and at 3 and 6 months after therapy, by conventional polymerase chain reaction tests. Results: Fourteen patients completed the study (n=7/group). Differences statistically significant were observed among both groups. The experimental group presented: A PPD mean (p=0.04) significantly lower and PPD reduction (p=0.02), at 6-months post NSPT. Regarding changes (∆), at the third month post NSPT, there was a significant increase in the number of shallow sites (p<0.001) and a decrease in the intermediate sites (p<0.001). In addition, a significant decrease in the mean number of deep sites (p=0.04) was detected at 6 months post treatment. There was also a significant decrease in periodontal index BoP at 1 (p=0.01), 3 (p<0.001) and 6 (p=0.01) months and OI at 3- and 6-months (p<0.001), post treatment. Regarding the presence of periodontal pathogens, no significant differences were observed, intra and inter groups. Conclusion: AZM as an adjuvant to NSPT provides additional beneficial effects for PPD and BoP compared to NSPT alone.

Objetivo: Evaluar el efecto de la administración sistémica de azitromicina (AZM) como coadyuvante de la terapia periodontal no quirúrgica (TPNQ) en las variables clínicas y microbiológicas de pacientes con periodontitis. Material y Métodos: Dieciocho voluntarios recibieron TPNQ combinado con placebo o AZM (500 mg/día) durante 3 días (n=9/grupo). Fueron monitoreados clínicamente para determinar Profundidad de Sondaje del Saco (PSS), Nivel de Inserción Clínica (NIC), Índice de O'Leary (IO), Sangrado al sondaje (SS) al inicio y durante el primer, tercer y sexto mes y microbiológicamente, al inicio y a los 3 y 6 meses después de la terapia, mediante la reacción en cadena de la polimerasa convencional. Resultados: Catorce pacientes completaron el estudio (n=7/grupo). Se observaron diferencias estadísticamente significativas entre ambos grupos. El grupo experimental presentó una media de PSS significativamente menor (p=0,04) y una reducción de PSS (p=0,02), a los 6 meses post TPNQ. En cuanto al delta (∆) pre y post tratamiento, al tercer mes post TPNQ, hubo un aumento significativo en el número de sitios poco profundos (p<0.001) y una disminución en los sitios intermedios (p<0.001). Además, se detectó una disminución significativa en la media de los sitios profundos (p=0.04) a los 6 meses post tratamiento. También hubo una disminución significativa en el índice SS al primer (p=0.01), tercer (p<0. 0 01) y sexto mes (p=0.01) post TPNQ y del IO al tercer y sexto mes (p<0.001), post tratamiento. En cuanto a la presencia de patógenos periodontales, no se observaron diferencias significativas tanto intra como ínter grupos. Conclusión: AZM como adyuvante a TPNQ proporciona efectos benéficos adicionales en la PSS y SS en comparación a TPNQ solo.

Comparison of gingival inflammatory parameters and pain perception on periodontal probing - a cross sectional study, part II / Comparación de parámetros inflamatorios gingivales y percepción del dolor en el sondaje periodontal - un estudio transversal, parte II

Background: Probing of the periodontal pocket is an essential part of the diagnosis of periodontal disease and 15-77% of untreated periodontal patients experience pain during probing. Therefore, the objective of this study is to evaluate the pain perceived by patients with dental plaque-induced gingivitis and chronic periodontitis during periodontal probing and the main objective includes the evaluation of the relationship between pain perceived during periodontal probing and gingival inflammatory parameters. Material and Methods: A total of 475 participants were recruited into the study. The patients were divided into two groups: Group-A (Gingivitis Group - 275 patients) and Group-B (Chronic Periodontitis Group - 200 patients). Clinical parameters included analysis of bleeding on probing, simplified gingival index, pocket depth on probing, and clinical attachment level. Pain score was recorded using the HP VAS scale and all patients participated in the study after a detailed explanation of the study protocol. Results: A significant difference in pain perception was noted between groups, highlighting the role of the degree of inflammation in the examination of periodontal parameters. Conclusion: Within the limitations of the present study, we can conclude that pain perception is directly correlated with the degree of inflammation in periodontitis rather than plaque-induced gingivitis during periodontal probing. Therefore, some form of adjuvant topical anesthesia may be considered in order to reduce pain levels in severely inflamed patients, to encourage continued acceptance of supportive periodontal therapy.

Antecedentes: El sondaje de la bolsa periodontal es una parte esencial en el diagnóstico de la enfermedad periodontal. 15-77% de los pacientes periodontales no tratados experimentan dolor durante el sondaje. Por lo tanto, el objetivo de este estudio es evaluar el dolor percibido por pacientes con gingivitis inducida por placa dental y periodontitis crónica durante el sondaje periodontal y el objetivo principal incluye la evaluación de la relación entre el dolor percibido durante el sondaje periodontal con parámetros inflamatorios gingivales. Material y Métodos: Un total de 475 sujetos fueron reclutados en el estudio. Los sujetos se dividieron en 2 grupos: Grupo - A (Grupo de gingivitis - 275 pacientes) y Grupo - B (Grupo de periodontitis crónica - 200 pacientes). Los parámetros clínicos incluyeron el análisis del sangrado al sondaje, el índice gingival simplificado, la profundidad de la bolsa al sondaje y el nivel de inserción clínica. La puntuación del dolor se registró utilizando la escala HP VAS y todos los pacientes participaron en el estudio después de una explicación detallada del protocolo del estudio. Resultados: Se notó una diferencia significativa en la percepción del dolor en el grupo B que en el grupo A, lo que significa el papel del grado de inflamación en el examen de los parámetros periodontales. Conclusión: Dentro de las limitaciones del presente estudio, podemos concluir que la percepción del dolor se correlaciona directamente con el grado de inflamación que se observa en la periodontitis más que con la gingivitis inducida por la placa dental durante el sondaje periodontal. Por lo tanto, se puede considerar alguna forma de anestesia tópica adyuvante para reducir los niveles de dolor en pacientes gravemente inflamados para fomentar la aceptación continua de la terapia periodontal de apoyo.

Periodontitis and its associated factors in patients at the faculty of southern Brazil: a cross - sectional study

To verify the presence of periodontitis, its severity, and their association with associated factors based on medical records of patients who attended the Dental Clinic of the Faculty of Southern Brazil over 4 years. This is a cross-sectional study, which included 422 medical records of patients aged ≥ 18 years. The clinically analyzed data were: plaque index (PI),bleeding on probing (BOP), probing pocket depth (PPD), and clinical attachment level (CAL). Sociodemographic data, dental hygiene, harmful habits and chronic systemic diseases were described. Statistical analysis of binary logistic regression was used to verify the relationship between the severity of periodontitis and the exposure variables. The older adults [odds ratio (OR) = 2.36; 95% confidence interval (CI): 1.23-4.54 ­41 to 55 years and OR = 3.0; 95% CI: 1.49-6.09 ­56 to 87 years], and men (OR = 1.9; 95% CI: 1.18-3.14) showed higher chances of periodontitis severity. Smokers (OR = 3.54; 95% CI: 2.05-6.12), those with hypertension (OR = 2.11; 95% CI: 1.23-3.63) and with diabetes (OR = 2.10; 95% CI: 1.08-4.12) showed higher chances of developing advanced periodontitis. Advanced or severe periodontitis occurred in one-third of the patients. The findings showed that men, older adults, with systemic arterial hypertension, diabetes mellitus, and smokers are more susceptible to severe periodontitis.

Efficacy of combined application of glycine powder air-polishing in non-surgical treatment of peri-implant diseases / 北京大学学报(医学版)

OBJECTIVE@#To compare the clinical efficacy of combined application of glycine powder air-polishing and mechanical submucosal debridement in non-surgical treatment of peri-implant diseases.@*METHODS@#A randomized controlled clinical study was carried out on patients diagnosed with peri-implant diseases in the Department of Periodontology, Peking University School and Hospital of Stomatology, between May of 2020 and June of 2021.Twenty-eight patients with totally sixty-two implants were enrolled.The patients were randomly divided into the test group and control group. The patients in the test group (13 subjects/32 implants) received mechanical submucosal debridement using titanium curettes combined with application of glycine powder air-polishing, while the control group (15 subjects/30 implants) received mechanical submucosal debridement using titanium only. Clinical parameters, such as plaque index (PLI), pocket probing depth (PPD), bleeding index (BI) and the percentage of suppuration on probing on implants' level (SoP%) were measured at baseline and 8 weeks after non-surgical intervention. Changes and group differences of clinical parameters of the implants before and 8 weeks after non-surgical intervention were compared.@*RESULTS@#Mean PLI, PPD, BI of both the test group and control group significantly reduced 8 weeks after non-surgical intervention (P < 0.05). Compared with the control group, the test group achieved lower BI (2.7±0.8 vs. 2.2±0.7, P < 0.05), more reduction of BI (0.6±0.7 vs. 1.1±0.6, P < 0.01) and more reduction of SoP% (21.9% vs. 10%, P < 0.05) after non-surgical intervention. Both the control and test groups exhibited comparable PLI and PPD reductions (P>0.05). For the implants diagnosed with peri-implant mucositis, the test group revealed more signi-ficant reduction in BI and SoP% than the control group (1.0±0.7 vs. 0.4±0.7, P=0.02; 6.3% vs. 0, P=0.012). There was no significant difference existing in PLI and PD improvement between the control group and test group (P>0.05). For the implants diagnosed with peri-implantitis, there was no significant difference existing in PLI, PPD, BI and SoP% improvement values between the test and control groups (P>0.05). No complications or discomforts were reported during the study.@*CONCLUSION@#Both treatment procedures could relieve the inflammation of peri-implant soft tissue. Non-surgical mechanical submucosal debridement combined application of glycine powder air-polishing is associated with significant reduction of soft tissue bleeding and suppuration on probing especially in the implants diagnosed with peri-implant mucositis.

Comparison of initial periodontal therapy and its correlation with white blood cell level in periodontitis patients with or without diabetes mellitus / 北京大学学报(医学版)

OBJECTIVE@#To compare the clinical efficacy of initial periodontal therapy in periodontitis patients with or without type 2 diabetes mellitus and its correlation with white blood cell counts.@*METHODS@#In this study, 32 chronic periodontitis patients without systemic disease (CP group) and 27 chronic periodontitis patients with type 2 diabetes mellitus (CP+DM group) were enrolled. At admission, all the patients went through periodontal examination and fasting blood examination(baseline). Probing depth (PD), attachment loss (AL), bleeding index (BI), plaque index (PLI), white blood cells (WBC) counts and fasting blood glucose (FBG) were recorded respectively, while hemoglobin A1c (HbA1c) was recorded only in CP+DM group. After that, initial periodontal therapy was performed. All the tests were repeated 3 and 6 months after treatment. The changes of periodontal clinical indexes and WBC levels were compared between the two groups before and after treatment, and the correlation between WBC and periodontal clinical indexes and glucose metabolism indexes were analyzed by generalized linear mixed model.@*RESULTS@#At baseline, the periodontal inflammation and destruction were similar in CP and CP+DM group, but the WBC level was significantly higher in CP+DM groups [(6.01±1.26)×109/L vs. (7.14±1.99)×109/L, P=0.01]. After 3 and 6 months of initial periodontal therapy, the mean PD, AL, BI, and PLI in CP+DM and CP groups were significantly lower than the baseline, and the PD in CP+DM group was further decreased by 6 months compared with 3 months [(3.33±0.62) mm vs. (3.61±0.60) mm, P < 0.05]. However, none of these periodontal indexes showed significant difference between the two groups by 3 or 6 months. In CP+DM group, HbA1c at 3 months and 6 months were significantly lower than the baseline [(7.09±0.79)% vs. (7.64±1.16)%, P < 0.05; (7.06±0.78)% vs. (7.64±1.16)%, P < 0.05], and FBG was significantly lower than the baseline by 6 months [(7.35±1.14) mmol/L vs. (8.40±1.43) mmol/L, P < 0.05]. The WBC level in CP group was significantly lower than the baseline level by 3 months [(5.35±1.37)×109/L vs. (6.01±1.26)×109/L, P < 0.05], while that in CP+DM group was significantly lower than the baseline level by 6 months [(6.00±1.37)×109/L vs. (7.14±1.99)×109/L, P < 0.05]. The analysis of genera-lized linear mixed model showed that WBC level was significantly positively correlated with PD and FBG (P < 0.05).@*CONCLUSION@#Initial periodontal therapy can effectively improve the periodontal clinical status of patients with or without type 2 diabetes mellitus, and have benefits on glycemic control in diabetic patients. However, the response of periodontal indexes and WBC level to initial therapy were relatively delayed in diabetic patients. WBC plays an important role in the correlation between diabetes mellitus and periodontitis.

Can Hemophilia Impact on the Oral Health Conditions of Children and Adolescents? A Systematic Review and Metanalysis

Abstract Objective: To analyze if the oral health conditions in children and adolescents are associated with hemophilia (PROSPERO-42020168192). Material and Methods: The search strategy was performed in PubMed, Scopus, Lilacs/BBO, Web of Science, Cochrane, and Grey literature databases. Two independent researchers assessed the risk of bias in these studies by the Newcastle-Ottawa Scale. For the meta-analysis, the clinical conditions data were extracted as numerical variables according to their indexes, such as dental caries experience (dmft/DMFT), gingival condition (Modified Gingival Index - IGM), and oral hygiene (Plaque Index - PI). The quality of the evidence of the meta-analysis was evaluated by the GRADE tool (GRADEproGDT). Results: From a total of 431 studies, 27 were included, and 10 were included in the meta-analysis. The studies presented a moderate risk of bias, ranging from 2 to 7 points. The dental caries experience in primary (-0.62; CI95%: -1.68-0.43) and permanent dentitions (-0.05; CI95%: -0.69-0.59), gingival condition (-0.12; CI95%: -0.27-0.03), and oral hygiene (0.36; CI95%: -0.06-0.77) did not differ between the groups. Conclusion: Based on studies with very weak evidence, there were no differences in the oral health conditions of children and adolescents with and without hemophilia (AU).

Evaluation of Antimicrobial Photodynamic Therapy as an Adjuvant in Periodontal Treatment in Individual with Down Syndrome

Abstract Objective: To evaluate the effectiveness of Antimicrobial Photodynamic Therapy (aPDT), associated with scaling and root planing in the non-surgical periodontal treatment of individuals with Down Syndrome. Material and Methods: A controlled, randomized, split-mouth study was conducted. A total of 8 participants diagnosed with Down Syndrome aged 17-38 years of both sexes with clinical periodontitis were included in the study. Participants were treated at least three times: at the baseline, Plaque Index (PI), Bleeding on Probing (BOP), and Probing Pocket Depth (PPD) were obtained. After one week, conventional scaling and root planing were performed, and two quadrants were randomly selected for aPDT application. The reassessment was obtained one month after the aPDT application. The significance level was set at 5%. Analyses were performed considering a 95% confidence interval. Results: In the intergroup evaluation, no statistically significant differences were observed (p>0.05). In the intragroup evaluation, no statistically significant variations were observed in relation to the PI (p>0.05) and PPD (p>0.05); however, a statistically significant reduction in the BOP was observed between the test group (p=0.013) and control group (p=0.015). Conclusion: The use of aPDT as adjuvant therapy did not promote additional benefits in decreasing PI and PPD after 1 month of treatment. However, a significant reduction in the BOP was observed in the intragroup evaluation.

The referral pattern of patients to periodontists by general dentists / O padrão de encaminhamento de pacientes para periodontistas por clínicos gerais

Objetivo: O sucesso da terapia periodontal requer um relacionamento adequado entre o clínico geral e o periodontista. O objetivo deste estudo foi determinar, por meio de um questionário, o padrão de encaminhamento de pacientes por dentistas clínicos gerais a periodontistas em Yazd, Irã. Material e Métodos: Este estudo transversal descritivo foi realizado na forma de uma pesquisa incluindo 145 dentistas licenciados em Yazd. Foi elaborado um questionário composto por sete questões com subquestões. Resultados: 89% dos cirurgiões-dentistas encaminham o paciente ao periodontista. A recessão gengival foi o motivo mais frequente de encaminhamento (69,7%), enquanto o sangramento gengival foi o menos frequente (13,1%). Em termos de procedimentos cirúrgicos, os procedimentos mais frequentes para encaminhamentos foram terapias de periimplantite e aumento de rebordo. O encaminhamento realizado por dentistas do gênero feminino foi de 95,9% e pelo gênero masculino foi de 81,7%. O número de pacientes encaminhados por dentistas que atuavam simultaneamente em clínicas privadas e públicas foi maior do que aqueles que atuavam apenas em clínicas privadas ou públicas. O maior percentual de encaminhamento foi no grupo de cirurgiões-dentistas com menos de 5 anos de experiência, com ligeira diferença daqueles com mais de 10 anos de experiência. Apenas 26,1% dos entrevistados relataram ter participado de programas de reciclagem. Conclusão: É necessário que os dentistas gerais considerem os sinais primários da doença periodontal e encaminhem os pacientes mais graves em estágios iniciais para fornecer um resultado ideal a longo prazo para os pacientes.(AU)

Objective: The successful periodontal therapy needs a proper relationship between general dentist and periodontist. The aim of this study was to determine the referral pattern of patients to periodontists by general dentists in Yazd, Iran, by means of a questionnaire. Material and Methods: This descriptive cross-sectional study was carried out in the form of a survey among 145 licensed general dental practitioners in Yazd, Iran. A questionnaire comprising of seven questions with sub-questions was prepared. Results: 89% of dentists have referred patient to periodontist. Gingival recession was the most frequent reason for referring (69.7%) and the least was gingival bleeding (13.1%). The most frequent surgical procedure for what patients have been referred were peri-implantitis therapy and ridge augmentation. Referral status to periodontist for female dentists was 95.9% and for male dentists was 81.7%. The number of referred patients form the dentists who were practicing simultaneously at both private and public clinics was higher than those who were practicing only at private or public clinics. The most referral percentage was in the group of dentists with less than 5 years of experience with a slight difference from those with more than 10 years of experience. Only 26.1% of the respondents have participated in retraining programs. Conclusion: There is a need for general dentists to consider the primary signs of periodontal disease and necessity of referring the patients in early stages more serious, to provide an optimal long-term outcome for patients.

Nivel de higiene y prevalencia de Porphyromona gingivalis y Fusobacterium nucleatum en pacientes recuperados de SARS-CoV-2 / Hygiene level and prevalence of Porphyromona gingivalis and Fusobacterium nucleatum in recovered SARS-CoV-2 patients

Introducción: El SARS-CoV-2 afecta el sistema respiratorio en diferentes grados. La cavidad oral es el lugar más colonizado por bacterias, por lo tanto, al no tener una adecuada higiene pueden presentarse diferentes enfermedades secundarias, lo que ha causado alerta en el gremio odontológico, ya que puede contribuir a complicaciones posteriores en los pacientes. Material y métodos: El estudio fue conformado por 47 pacientes voluntarios recuperados de SARS-CoV-2, residentes de Montemorelos, Nuevo León, México, donde fueron atendidos en Bucalia Dent, consultorio dental. Después del consentimiento informado de cada paciente, se realizó una historia clínica para conocer los síntomas, enfermedades sistémicas, ausencia de dientes y nivel de inflamación gingival de acuerdo al índice de Loe y Silness. A continuación, se tomó una muestra de biofilm microbiano (placa dentobacteriana), la cual se suspendió en una solución buffer de fosfato, posteriormente fue llevada al Centro de Investigación y Desarrollo en Ciencias de la Salud (CIDICS), Monterrey, N.L, México. Se extrajo DNA y se purificó, después se realizó PCR para detectar los patógenos orales; la PCR se visualizó en gel de agarosa (1.5%) por tinción de bromuro de etidio. Resultados: Se detectó 80.85% Porphyromona gingivalis y 68.09% Fusobacterium nucleatum en pacientes recuperados de SARS-CoV-2; 23.4% presentaron inflamación leve de acuerdo al índice de Loe y Silness, 54.5% fueron masculinos y 45.5% femeninos. Por otro lado, 36.4% de los pacientes con inflamación leve tenían de cuatro a seis dientes ausentes. En estos pacientes se detectó 18.18% únicamente con Fusobacterium nucleatum y 27.27% sólo con Porphyromona gingivalis; el sexo masculino tuvo predisposición en 66.6% y el femenino en 33.33%. Se observó infección con los dos patógenos presentes en 45.45%; y 60% de estos pacientes fueron masculinos. Conclusiones: Los pacientes recuperados de SARSCoV- 2 analizados en esta investigación mostraron mala higiene oral y alta prevalencia de los patógenos mencionados altamente relacionados a inflamación gingival o enfermedad periodontal, lo que nos indica que es indispensable la intervención del odontólogo al finalizar el periodo de infección de cada paciente (AU)

Introduction: SARS-CoV-2 affects the respiratory system to different degrees. The oral cavity is a colonized place by bacterias, therefore, by not having good hygiene, different secondary diseases can occur; this has caused an alert in the dental industry, since it can contribute to later complications in patients. Material and methods: The study was conducted in 47 SARS-CoV-2 recovered volunteers from the Montemorelos city of the Nuevo León state, Mexico, who were attended at the Bucalia Dent dental clinic. An informed consent was obtained from each of the patients, then their clinical history was documented in order to know the symptoms, previous systemic diseases, absence of teeth and degree of gingival inflammation, as suggested by Loe and Silness. Subsequently, a dental plaque sample was taken from all patients, which was suspended in a phosphate buffered solution and shipped to The Center for Research and Development in Health Sciences (CIDICS), Monterrey, NL, Mexico for storage. DNA extraction and purification was performed and PCR was carried out for the oral pathogens detection. All PCR products were visualized on 1.5% agarose gel by ethidium bromide staining. Results: Porphyromona gingivalis and Fusobacterium nucleatum were detected in 80.85% and 68.09% of SARS-CoV-2 recovered patients, respectively. 23.4% showed mild inflammation based on the Loe and Silness criteria, 54.5% were male and 45.5% female. On the other hand, 36.4% of patients with mild inflammation had between 4 to 6 missing teeth. A single infection by Fusobacterium nucleatum was detected in 18.18% and by Porphyromona gingivalis in 27.27%; the male sex had a predisposition with 66.66% and 33.33% female; coinfection of both pathogens was observed in 45.45% where 60% were male. Conclusions: SARS-CoV-2 recovered patients show poor oral hygiene and a high prevalence of oral pathogens related to the development of inflammatory gingival or periodontal disease, this suggests the need for an odontological clinical intervention at the end of the course of infection or disease caused by SARS-CoV-2 (AU)

Índice de necesidad de tratamiento periodontal en embarazadas y no embarazadas que asisten a la maternidad provincial de Córdoba, Argentina / Periodontal index for treatment needs in pregnant and non-pregnant women attending the provincial maternity hospital in Córdoba, Argentina

Objetivo: Comparar la salud periodontal de embaraza- das y no embarazadas mediante la aplicación del Índice de Periodontal Comunitario (IPC). Materiales y métodos: Se realizó un estudio ob- servacional de corte transversal. Se reclutaron 100 mujeres embarazadas (EMB) y 50 no embarazadas (NoEMB) que concurrieron al Hospital Materno Provincial de la Ciudad de Córdoba, Dr. Raúl F. Lucini. En todas se registró el IPC con la sonda periodontal WHO 621 en los 6 sextantes de la boca. Los datos se analizaron con el software Infostat/SP; el nivel de significación establecido fue de P <0,05. Resultados: El 70% de las pacientes presentó edades de entre 18 y 25 años. En las EMB el código 3 del IPC fue el más frecuente presente en 240 sextantes (40,1%) y en las NoEMB el código 2 fue el más frecuente con 39 sextantes (43%). A ambos grupos de estudio les corresponde el trata- miento de instrucción de higiene bucal, instrumentación supra y/o subgingival, y/o regularización de obturaciones. Conclusiones: El código 3 fue el más frecuente entre las EMB, a quienes les corresponde un Código de tratamiento periodontal (CTP) 2; las NoEMB presentaron un IPC de 1 y 2 como los más frecuentes y se vinculan con un CTP 1 y 2. Nos encontramos frente a una situación clínica periodontal posible de resolver con terapia básica que puede ser realizada por odontólogos generalistas (AU)

Aim: To compare the periodontal health of pregnant and non-pregnant women by applying the Community Periodontal Index (CPI). Materials and methods: In an observational, cross-sec- tional study, 100 pregnant women (PREG) and 50 non-preg- nant women (NonPREG) were recruited at the Dr. Raúl F. Lu- cini Provincial Maternity Hospital in Córdoba City. The CPI was determined in the 6 sextants of the mouth using a WHO 621 periodontal probe. The data were analyzed with Infostat SP software. P <0.05 was considered significant. Results: 70% of the patients were 18 to 25 years old. In the PREG group, CPI Code 3 was the most frequent, present in 240 sextants (40.1%), while in the non-PREG group, CPI Code 2 was the most frequent, with 39 sextants (43%). Treat- ment needs in both study groups are oral hygiene instruction, supra- and/or subgingival instrumentation, and/or correction of plaque retentive margins. Conclusions: Code 3 was the most frequent among preg- nant women, which corresponded to Periodontal Treatment Code (CTP) 2. CPI 1 and 2 were the most frequent in non-pregnant women, corresponding to CTP 1 and 2. This periodontal clinical condition can be treated with initial dental hygiene therapy, which can be performed by general dentists (AU)

Doença cardiovascular e periodontite: análise de série de casos avaliando níveis de Proteína C-Reativa / Cardiovascular disease and periodontitis: case series analysis evaluating C-Reative Protein levels

As periodontopatias podem ser dos principais fatores para o agravamento de doenças, como alterações cardiovasculares. Microrganismos e produtos bacterianos encontrados nessas condições provocam intensa produção de mediadores inflamatórios, incluindo a proteína C-reativa (PCR), marcador para cardiopatias. Avaliou-se a relação dos níveis plasmáticos de PCR em pacientes com doenças cardiovasculares (DCV) e periodontite. Uma série de quatro casos acompanhados/ concluídos na referida clínica (idade entre 24 e 61 anos, todos homens). Constatada a condição de periodontite, o periograma do sextante comprometido foi realizado, junto à requisição de exames para dosagem dos níveis plasmáticos de PCR, antes e após sessão de raspagem e alisamento radicular. Em 21 a 30 dias, um periograma reavaliativo foi realizado para análise comparativa das pro fundidades de sondagem e níveis de PCR antes e após a sessão de instrumentação. Houve redução de 13,7% (paciente "A") e até 2 mm na perda de inserção (pacientes "A" e "C") dos sítios avaliados; não houve nenhuma mudança significativa nas novas dosagens dos níveis de PCR. Conclui-se que não foi possível demonstrar uma correlação entre os níveis de PCR em pacientes que apresentam concomitantemente DCV e periodontite, nesta série de casos... (AU)

Periodontal diseases are one of the main factors for aggravation of diseases, such as cardiovascular alterations. Microorganisms and bacterial products found under these conditions provoke intense production of inflammatory mediators, including C-reactive protein (CRP), a marker for cardiovascular disease. It was evaluated the relationship of plasma levels of CRP in patients with Cardiovascular Diseases (CVD) and periodontitis in the dental clinic of the UPE campus Arcoverde. A series of four cases followed at the clinic (24 to 61 years old, all men). Condition of periodontitis confirmed, the periogram of the compromised sextant was performed, together with the requisition of tests for the determination of plasma levels of CRP, before and after scaling and root planing sessions. Around 21-30 days a re-evaluating periogram was performed for comparative analysis of depths of probing and CRP levels before and after the instrumentation. There was a reduction of 13.7% (patient "A") and up to 2 mm in the loss of insertion (patients "A" and "C") of the evaluated sites; there wasn't significant change in the new doses of CRP levels. It's concluded was not possible to demonstrate a correlation between CRP levels in patients with concomitant CVD and periodontitis in this case series... (AU)

Investigation of patients with coronary slow flow in terms of periodontal health status

SUMMARY OBJECTIVE: This study aims to evaluate the relationship between periodontal health status and coronary slow flow phenomenon. METHODS: One hundred and two patients who underwent coronary angiography with the diagnosis of stable angina pectoris were included in the study. Patients were divided into two groups: patients with coronary slow flow (Test group) (n=51), and patients with normal coronary angiography (Control group) (n=51). Diagnosis of slow coronary flow was made according to Beltrame criteria by coronary angiography. Demographic characteristics of the participants were recorded. The periodontal health was assessed by clinical periodontal parameters such as probing depth, clinical attachment level, gingival index, plaque index, and bleeding on probing. RESULTS: There were no significant differences between groups as regards the frequencies of hypertension, smoking (p>0.05). As for the periodontal parameters of the study groups, probing depth, gingival index, plaque index, bleeding on probing, and clinical attachment level values were statistically higher in the test group compared to the control group (p<0.05). CONCLUSIONS: Periodontitis might be accepted as one of the underlying causes of coronary slow flow. Patients with coronary slow flow should be evaluated for an underlying periodontal disease, and treatment of periodontal disease can protect against future cardiovascular events.

Dental Status of Firefighters of Rio de Janeiro State and Comparison with Brazilian Oral Health Surveys

ABSTRACT Objective: This cross-sectional study aimed to assess clinical dental status in military firefighters of Rio de Janeiro State and compare data with Brazilian National and Regional oral health surveys. Material and Methods: A sample of 926 military firefighters was examined using the visible biofilm index, the DMFT index and the Community Periodontal Index (CPI). Clinical exams were performed by 15 trained dentists. The Kruskal-Wallis test and Mann-Whitney test with Bonferroni correction were used. Results: Higher biofilm accumulation was associated with increased age. The mean DMFT index for the whole sample of this study was 12.74 (±7.03), and the 'filled' component was the most prevalent (69.9%), whereas the 'decayed' and 'missing' components were, respectively, 8.4% and 21.7%. There was a higher prevalence of periodontal diseases with increasing age, ranging from 57.1% in firefighters of 34 years or less to 70.5% in the ones between 35 and 44 years old and 75.4% in participants at age 45 years or older. Clinical dental status of the military firefighters who belonged to the age group 35-44 was better than the one observed for the Brazilian population at the same age range. However, pathological conditions that can be solved with health promotion strategies associated with dental procedures of low complexity still persist. Conclusion: These results suggest that the availability of dental health care services itself does not represent the most effective approach to the oral health problems found in the studied population.

Periodontal Comparison on Systemic Lupus Erythematosus Patients and Healthy Subjects: A Cross-Sectional Study

ABSTRACT Objective: To analyze periodontal comparison between Systemic Lupus Erythematosus (SLE) subject and healthy control. Material and Methods: This descriptive cross-sectional study included 122 subjects, 61 SLE patients and 61 healthy subjects who visited the Rheumatology Department, Dr. Saiful Anwar General Hospital, Malang, during 2017-2018. Clinical examination of SLE was using Mexican SLE Disease Activity Index and oral cavity conditions were assessed using the periodontal index, gingival index, calculus index, bleeding on probing, clinical attachment loss and mobility teeth. Results: The age of SLE patients ranged from 18-55 years old with the mean age of 29.50 ± 9.57 years old. Periodontitis was higher in SLE patients (88.5%) than healthy subjects (22.95%). In addition, periodontitis occurrence in SLE (2.66 ± 1.02) was significantly different (p<0.001) compared to healthy subjects (0.51 ± 0.81). Conclusion: This study found higher rates of periodontitis, gingivitis, bleeding on probing, clinical attachment loss, and mobility tooth among SLE patients compared to healthy subjects. Periodontitis was also found to be higher along with more severe SLE group.

Desfechos periodontais e qualidade de vida relacionada à saúde bucal em indivíduos de transplante de células tronco hematopoiéticas, fígado e rim: um estudo transversal comparativo / Periodontal outcomes and quality of life related to oral health in hematopoietic stem, liver and kidney transplant individuals: a comparative cross-sectional study

Esse estudo observacional transversal comparativo teve como objetivos avaliar os parâmetros clínicos periodontais, índice gengival modificado (IGM), índice de placa visível (IPV), crescimento gengival induzido por drogas (CGID), mensurar volume e fluxo do fluido crevicular gengival (FCG), perda dentária bem como o impacto da saúde bucal auto-relatada na qualidade de vida, em pacientes pré e pós-transplante de células tronco hematopoiéticas (TCTH), fígado (TX-fígado), rim (Tx-rim), comparados a indivíduos sem doença sistêmica diagnosticada. O estudo foi aprovado pelo Comitê de Ética em Pesquisa da Universidade Federal de Minas Gerais (UFMG) (CAAE-18019619.1.0000.5149). A amostra foi recrutada dentre usuários da Faculdade de Odontologia da UFMG, de março a dezembro de 2019. Foram registrados: IGM, IPV, profundidade à sondagem (PS), sangramento à sondagem (SS), nível de inserção clínico (NIC), recessão gengival (RG), CGID, fluxo e volume do FCG e número de dentes presentes. O instrumento Oral Health Impact Profile (OHIP-14) foi aplicado para avaliar a Qualidade de Vida Relacionada à Saúde Bucal (QVRSB). O grupo controle incluiu pacientes sem doença sistêmica diagnosticada, pareados por sexo e idade. Os dados foram analisados pelo programa SPSS versão 25. Análises descritivas e comparativas foram realizadas usando os testes de Wilcoxon, Mann Whitney e Kruskal-Wallis seguido de Dunn-Bonferroni. Modelos de regressão logística binária condicional estimaram a Odds-Ratio, considerando como desfechos presença de periodontite e prevalência de alto impacto na QVRSB. Em todos os testes, o nível de significância de 5% foi adotado. As frequências de periodontite foram maiores em indivíduos em condição de transplante que no grupo controle, na fase pré-transplante e nos pacientes Tx-fígado. O diagnóstico mais frequentemente encontrado foi a periodontite estágio I localizada. As medianas de IPV, PS, NIC, volume e fluxo do FCG foram maiores em pacientes de transplante comparados aos controles (p<0,05). Comparados aos respectivos controles, os grupos Tx-fígado e Tx-rim apresentaram medianas de IPV e PS significativamente maiores. O número de dentes presentes foi menor no grupo Tx fígado que no Tx rim (p=0,027). No modelo ajustado final, nenhuma variável mostrou associação com a presença de periodontite (p>0,05). Pacientes de transplante tiveram pior percepção do impacto na QVRSB que os indivíduos controle (p=0,015). Os grupos TCTH (p=0,008) e Tx-fígado (p=0,033) foram mais impactados que seus controles. Na regressão logística, a variável transplante não afetou a frequência de alto impacto na QVRSB. No modelo final ajustado, a escolaridade e o número de dentes presentes permaneceram como fatores preditores do impacto da saúde bucal na qualidade de vida auto-relatada. Indivíduos com menor escolaridade (OR = 3,590; 1,021-12,622) e com menor número de dentes (OR = 4,991; IC95% 1,386-17,970) tiveram maior impacto na QVRSB. Concluiu-se, que as frequências de periodontite foram maiores em indivíduos em condição de transplante, na fase pré e em pacientes Tx-fígado. A periodontite estágio I localizada foi o diagnóstico mais frequente. A condição de transplante não afetou a presença de periodontite. O número de dentes presentes e a escolaridade tiveram impacto na QVRSB dos indivíduos em condição transplante, e estes demonstram uma pior percepção que os controles.

This cross-sectional observational study aimed to assess periodontal clinical parameters, modified gingival index (MGI), visible plaque index (VPI), drug-induced gingival overgrowth (DIGO), measuring gingival crevicular fluid (GCF) volume and flow , tooth loss as well as the impact of self-reported oral health on quality of life, in patients before and after hematopoietic stem cell (HSCT), liver (Tx-liver), kidney (Tx-kidney) transplantation compared to individuals without diagnosed systemic disease. The study was approved by the Research Ethics Committee of the Federal University of Minas Gerais (UFMG) (CAAE-18019619.1.0000.5149). The sample was recruited from users of the Faculty of Dentistry at UFMG, from March to December 2019. The outcomes MGI, VPI, probing depth (PD), bleeding on probing (BoP), clinical attachment level (CAL), gingival recession (GR), DIGO, flow and volume of GCF and number of teeth present were recorded. The Oral Health Impact Profile instrument (OHIP-14) was applied to assess the Oral Health Related Quality of Life (HRQoL). The control group included patients without diagnosed systemic disease, matched for sex and age. The data were analyzed using the SPSS software version 25. Descriptive and comparative analyzes were performed using the Wilcoxon, Mann-Whitney and KruskalWallis followed by Dunn-Bonferroni tests. To estimate the Odds-Ratio, conditional binary logistic regression models were used, considering as outcomes presence of periodontites and prevalence of hight impact on OHRQoL. In all tests, the significance level of 5% was adopted. The frequency of periodontitis was higher in individuals undergoing transplantation than in the control group, in the pre-transplant phase and in Tx-liver patients. The most frequently found diagnosis was localized stage I periodontitis. The medians of VPI, PD, CAL, GCF volume and flow were higher in transplant patients compared to controls (p <0.05). The Tx-liver and Tx-kidney groups had significantly higher VPI and PD medians than their respectives controls. Comparing the transplant groups, the number of teeth present was lower in Tx-liver than in Tx-kidney (p = 0.027). In the final adjusted model, no variable was associated with the presence of periodontitis (p> 0.05). Transplant patients had a worse perception of the impact on OHRQoL than control subjects (p = 0.015). The groups HSCT (p = 0.008) and Tx-liver (p = 0.033) were more impacted than their controls. In logistic regression, the transplant variable did not affect the frequency of high impact on OHRQoL. In the final adjusted model, schooling and the number of teeth present remained as predictors of the impact of oral health on self-reported quality of life. Individuals with less education (OR = 3.590; 1.021-12.622) and with fewer teeth (OR = 4.991; 95% CI 1.386-17.970) had a greater impact on HRQoL. It was concluded that the frequencies of periodontitis were higher in individuals in a transplant condition, in the pre-transplantation phase and in Tx-liver patients. Localized stage I periodontitis was the most frequent diagnosis. The transplant condition did not affect the presence of periodontitis. The number of teeth present and education had an impact on the HRQoL of transplantation individuals, and these demonstrate a worse perception than the controls.
