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.

The Effect of Periodontal and Peri-Implanter Health on IL-1 and TNF- Levels in Gingival Crevicular and Peri-Implanter Sulcus Fluid: a Cross-Sectional Study / El efecto de la salud periodontal y peri-implantar en niveles de IL-1ß y TNF-α en el fluido crevicular y sulcus peri-implantador: un estudio transversal

Abstract: It is stated that peri-implanter diseases have destructive effects similar to periodontal diseases. This study aims to compare IL-1β and TNF-α levels in healthy and diseased areas. Forty non-smokers systemically health individuals (40 implants/40 teeth) (age:38-67) were included in the study. In clinical and radiographic examinations; plaque index (PIn), gingival index (GI), periodontal pocket depth (PPD), clinical attachment level (CAL) and marginal bone loss (MBL) values were recorded. The gingival crevicular fluid (GCF) and peri-implanter sulcus fluids (PISF) of the patients were collected, and IL-1β and TNF-α levels were measured by ELISA in the samples. The collected data were analyzed with the help of SPSS v.22 package program. Sample PPD score showed a statistically significant difference between the diseased and healthy groups and also sample CAL showed statistically significant higher in Periodontitis(P) compared to periodontally heathy(H) and Gingivitis(G) (p>0.05). IL-1beta and TNF-α levels in GCF/PISF; In the P and Peri-implantitis (PI) group, it was found statistically significantly higher than the H, Healthy-Implant (HI), besides P showed higher levels compared to G (p<0.05). Within the limitations of our study, it can be said that IL-1β and TNF-α among inflammatory cytokines in GCF/PISF will increase in periodontal and peri-implanter diseases, it can also be said that this increase in cytokines may indicate that periodontal and peri-implanter diseases have similar immunological structure. Peri-implant mucositis without periodontitis history has similarity to peri-implantitis and periodontitis in terms of IL-1β and TNF-α levels in GCF/PISF.

Resumen: Se afirma que las enfermedades peri-implantarias tienen efectos destructivos similares a los de las enfermedades periodontales. Este estudio tiene como objetivo comparar los niveles de IL-1β y TNF-α en zonas sanas y enfermas. Cuarenta individuos no fumadores con salud sistémica (40 implantes/40 dientes) (edad:38-67) fueron incluidos en el estudio. En los exámenes clínicos y radiográficos se registraron los valores de índice de placa (PIn), índice gingival (GI), profundidad de la bolsa periodontal (PPD), nivel de fijación clínica (CAL) y pérdida de hueso marginal (MBL). Se recogieron los fluidos creviculares gingivales (GCF) y los fluidos del surco peri-implantario (PISF) de los pacientes, y se midieron los niveles de IL-1β y TNF-α mediante ELISA en las muestras. Los datos recogidos fueron analizados con la ayuda del programa de paquete SPSS v.22. La puntuación PPD de la muestra mostró una diferencia estadísticamente significativa entre los grupos enfermos y sanos y también la muestra CAL mostró estadísticamente significativa más alta en la Periodontitis (P) en comparación con la salud periodontal (H) y la Gingivitis (G) (p>0.05). Los niveles de IL-1beta y TNF-α en GCF/PISF. En el grupo de P y Peri-implantitis (PI), se encontró estadísticamente significativo más alto que el H, implante sano (HI), además P mostró niveles más altos en comparación con G (p<0.05). Dentro de las limitaciones de nuestro estudio, se puede decir que IL-1β y TNF-α entre las citoquinas inflamatorias en GCF/PISF aumentarán en las enfermedades periodontales y peri-implantarias. También se puede decir que este aumento de citoquinas puede indicar que las enfermedades periodontales y peri-implantarias tienen una estructura inmunológica similar. La mucositis peri-implantaria sin antecedentes de periodontitis tiene similitudes con la peri-implantitis y la periodontitis en cuanto a los niveles de IL-1β y TNF-α en la GCF/PISF.

Periodontal disease and its complications in cats from a shelter in the Central Region of Rio Grande do Sul / Doença periodontal e suas complicações em gatos de um abrigo na Região Central do Rio Grande do Sul

Periodontal disease is the most common infectious disease that occurs in feline patients. Although it occurs in both sexes, different age groups, and any breeds, the prevalence and severity seem much higher in cats living in animal shelters. This paper aimed to describe the clinical, radiological, cytopathological, and virological aspects of periodontal disease and its complications in cats, based on these aspects and, consequently, on the importance it brings to cat feline medicine in shelter cats. For this, nine cats with periodontal disease from a single animal shelter were evaluated. These cats demonstrated a disease characterized by halitosis, excessive salivation, and oral discomfort. Lymphadenomegaly of the mandibular and retropharyngeal lymph nodes was observed in 44.4% of the cases. Oral lesions consisted of varying degrees of gingival hyperemia, complete loss of free gingival margins, and consequently gingival retraction, dental calculus deposition, dental mobility, complete exposure of the furcation of premolars and molars, and dental roots of canines and incisors, loss of bone radiopacity due to alveolar bone resorption and tooth loss. Complications included chronic ulcerative paradental stomatitis (22.2%), faucitis (22.2%), and chronic gingivostomatitis (11.1%). None of the cats affected by periodontal disease was positive for FIV or FeLV. In 33.3% of the cases, cats were carriers of feline calicivirus, but not feline herpesvirus.(AU)

Doença periodontal é a mais comum doença infecciosa que ocorre em pacientes felinos. Embora ocorra em gatos de ambos os sexos, diferentes faixas etárias e quaisquer raças, a prevalência e a gravidade parece muito maior em gatos que vivem em abrigos para animais. Baseado nesses aspectos e, consequentemente, na importância que ela traz para a medicina felina de gatos de abrigos, o objetivo desse artigo é descrever os aspectos clínicos, radiológicos, citopatológicos e virológicos da doença periodontal e suas complicações em gatos. Para isso, nove gatos com doença periodontal oriundos de um único abrigo de animais foram avaliados. Esses gatos demonstraram uma doença caracterizada por halitose, salivação excessiva e desconforto oral. Linfadenomegalia dos linfonodos mandibulares e retrofaríngeos foi observada em 44,4% dos casos. As lesões orais consistiam de graus variados de hiperemia gengival, perda completa das margens gengivais livres e, consequentemente, retração gengival, deposição de cálculo dental, mobilidade dentária, exposição completa da furca dos pré-molares e molares e das raízes dentárias dos caninos e incisivos, perda de radiopacidade óssea devido à reabsorção de osso alveolar e perda dentária. Complicações incluíram estomatite paradental ulcerativa crônica (22,2%), faucite (22,2%) e gengivoestomatite crônica (11,1%). Nenhum dos gatos afetados pela doença periodontal foi positivo para FIV ou FeLV. Em 33,3% dos casos, os gatos eram portadores do calicivírus felino, mas não do herpesvírus felino.(AU)

Periodontal Tissue Condition on Systemic Lupus Erythematosus Patients: A Clinical Study

Abstract Objective: To evaluate periodontal tissue condition on systemic lupus erythematosus (SLE) patients and its characteristics. Material and Methods: This descriptive and cross-sectional study involved 61 SLE patients. Clinical examination of the oral cavity was performed using periodontal index (PI), gingival index (GI), clinical attachment loss (CAL) and number of loose teeth. Also, we evaluated SLE duration, treatment duration, ethnics, marital status, educational background, family income, and occupation. Results: In the evaluation of periodontal tissue, 93.4% had bleeding on probing, 80.3% clinical attachment loss, and 16.3% loose teeth. A total of 54 patients (88.5%) with SLE had periodontitis. Seven subjects had no periodontitis, 11 mild periodontitis, 29 moderate periodontitis and 14 severe periodontitis. Mean Periodontal Index score, Gingival Index, Clinical Attachment Loss (mm), and the number of mobility teeth, Plaque Index and Calculus Index respectively were 2.66 ± 1.20, 1.95 ± 1.02, 0.75 ± 0.59 mm, 1,49 ± 1.77. There was a significant difference in periodontal index score, shown periodontitis between employment and unemployment subjects (p=0.004) and a moderate correlation between periodontitis and occupation. Conclusion: Periodontitis found as manifestations SLE patients, followed by bleeding on probing and loose teeth. Its characteristics is playing a role in periodontitis in SLE patients.

Periodontal disease and its impact on general health in Latin America: LAOHA Consensus Meeting Report

Abstract: Periodontal diseases are considered a worldwide public health problem, owing to their high prevalence in developed and developing countries. Periodontitis may lead to tooth loss, which can impact oral health-related quality of life. Gingivitis and periodontitis have been extensively studied regarding their etiopathogenesis, epidemiology, prevention and treatment outcomes. However, most of these aspects are studied and discussed globally, which may hamper a clear interpretation of the findings and the design of effective plans of action for specific regions or populations. For example, in Latin America, epidemiological data about the distribution of periodontal diseases is still scarce, mainly when it comes to nationwide representative samples. This Consensus aimed to address the following topics related to periodontal diseases in Latin America: a) The impact of the global burden of periodontal diseases on health: a global reality; b) Periodontal diseases in Latin America; c) Strategies for the prevention of periodontal diseases in Latin America; d) Problems associated with diagnosis of periodontal conditions and possible solutions for Latin America; e) Treatment of Periodontitis. This consensus will help to increase awareness about diagnosis, prevention and treatment of periodontal diseases, in the context of Latin American countries.

Periotestometry and tissue hydration. How are these indicators related?

The mobility of teeth in terms of periotestometry and hydration of periodontal tissues in terms of bioimpedance spectrometry were studied in healthy volunteers without dental and concomitant somatic diseases. It was found that teeth of these subjects have both low and pathological mobility. It was also revealed as increased hydration (edema), indicating the presence of inflammation, and reduced hydration, indicating atrophic processes in periodontal tissues. A comparison of the data of periotestometry and bioimpedance spectrometry showed that the indicators of mobility of the teeth and hydration of the periodontal tissues reflect different characteristics of the functional state of dentoalveolar system, and can be used as complementary in the diagnostic studies.

La plausibilidad biológica entre la periodontitis crónica y el infarto cerebral isquémico / Biological plausibility of the relationship between chronic periodontitis and ischemic stroke

Introducción: Las bolsas periodontales reales constituyen un reservorio importante de bacterias gramnegativas que pueden por diversas vías ejercer influencia en sitios distantes, lo cual provoca alteraciones sistémicas como las enfermedades derivadas de la aterosclerosis. Objetivo: Explicar los fundamentos teóricos que sustentan la propuesta de la periodontitis crónica como un factor de riesgo para el infarto cerebral isquémico. Contenido: 1) La aterosclerosis y las enfermedades cerebrovasculares, generalidades de su patogenia. 2) La microbiota periodontal, fundamentos de su asociación con la aterosclerosis y la enfermedad cerebrovascular isquémica. Exposición del tema: La inflamación es un elemento de vital importancia en todas las fases del proceso aterosclerótico, tanto en su inicio, progresión, como en sus complicaciones. La naturaleza de las enfermedades periodontales inmunoinflamatorias crónicas y la infección subgingival anaerobia asociada a ellas, representa una injuria metastásica que produce y disemina mediadores inflamatorios favorecedores de la ateroesclerosis, participando en la colonización, y ruptura de placas ateromatosas; procesos implicados en la patogenia del infarto cerebral isquémico. Consideraciones finales: El mayor conocimiento de la relación riesgosa entre periodontitis crónica e infarto cerebral isquémico, permitiría una utilización racional de estrategias de prevención y tratamiento de la enfermedad cerebrovascular, basadas en la detección de procesos inflamatorios como las periodontopatías crónicas(AU)

Introduction: True periodontal pockets are an important reservoir of gram-negative bacteria which may exert an influence on distant sites in a variety of manners, bringing about systemic alterations such as diseases derived from atherosclerosis. Objective: Explain the theoretical foundations supporting the proposal of chronic periodontitis as a risk factor for ischemic stroke. Content: 1) Atherosclerosis and cerebrovascular disease, an overview of their pathogenesis. 2) The periodontal microbiota, bases for its association with atherosclerosis and ischemic stroke Topic presentation: Inflammation is an element of vital importance in all the stages of the atherosclerotic process, be it its onset, progress or complications. By their nature, chronic immunoinflammatory periodontal diseases and the associated anaerobic subgingival infection, constitute a metastatic injury that produces and spreads inflammatory mediators leading to atherosclerosis and participating in the colonization and rupture of atheromatous plaques, which are processes involved in the pathogenesis of ischemic stroke. Final considerations: Better knowledge about the risk relationship between chronic periodontitis and ischemic stroke would allow a rational use of strategies for the prevention and treatment of cerebrovascular disease based on detection of inflammatory processes such as chronic periodontal conditions(AU)

Effect of Scaling and Root Planing Treatment on Levels Hs-CRP in Indonesian Patients with Risk of Cardiovascular Disease

Objective: To determine the effect of scaling and root planning treatment on levels of hs-CRP (C-reactive protein) in patients with risk of cardiovascular disease. Material and Methods: This research is an experimental research with one group pre- and post-test design. This research was performed to the periodontal patients who came to the clinic and have risk of cardiovascular disease. Medical evaluations included measurement of blood pressure and body mass index were performed. Blood samples were obtained from each subject after over night fasting, highsensitivity C-reactive protein was measured as an index of inflammation. Blood samples were analysed two times before treatment (scaling and root planning) and three weeks later. Statistical analysis used Paired t-test. The level of significance was set at 5%. Results: Means-CRP levels before and after treatment in scaling and root planning were 3.16 ± 2.37 and 2.18±1.56 (p=0.007). Conclusion: There are significant differences between hs-CRP levels before and after treatment.

Efficacy of Two Different Toothbrushes on Plaque Control: A Randomized Clinical Study

Objective: This parallel, randomized, examiner-blind clinical trial aimed to evaluate the efficacy of two different toothbrushes (manual and sonic) on plaque control in adolescents. Material and Methods: This study enrolled 56 volunteers, randomly allocated to two different groups: group A (n = 28) for the manual toothbrush (Curaprox 5460 Ultra Soft®) and group B (n = 28) for the sonic toothbrush (Edel White®). Mean age was 17.2 ± 1.1 years. A calibrated periodontist performed a periodontal evaluation to assess the presence of plaque with the Turesky Modification of the Quigley Hein Plaque Index (PI) and the gingival inflammation with the Silness & Löe Gingival Index (GI). Adolescents received instructions about the mechanical control of plaque at baseline (T0), with a reexamination after 3 months (T1) and 6 months (T2). Non-parametric Mann Whitney test was used to compare the differences between the two toothbrush groups and the Friedman test was used for the comparisons between times. Results: There has been PI reduction concerning the study times (T0, T1 and T2, p<0.05), but not between the groups A and B (p>0.05). As for GI there has been no significant difference between the groups and between the study times (p>0.05). Conclusion: Both toothbrushes were efficient in the control of supragingival plaque (visible biofilm).

Prevalence of Caries and Periodontal Disease Among Indonesian Pregnant Women

Objective: To determine the extent of bleeding on probing, probing pocket depth and the level of oral hygiene and caries prevalence among pregnant women. Material and Methods: Random samples of pregnant women attending eight public health centers were examined. Their periodontal and caries statuses were examined using the Community Periodontal Index, Simplified Oral Hygiene Index and DMF-T. The good criteria of OHI-S ranged from 0 to 1.2, the fair from 1.3 to 3.0 and the poor from 3.1 to 6.0. Descriptive statistics were used to calculate the absolute and relative frequencies. Results: 84.7% had caries and the DMF-T index score was 4.34 (fair). 73% suffered gingival bleeding, 34% with 4-5 mm pocket depth, 2% with 6 mm or deeper pocket depth, while the majority had good oral hygiene. The prevalence of 4-5 mm probing pocket depth increased between the first and second trimesters (12.1% to 48.5%), before undergoing a slight decrease in the third trimester (39.4%). Gingival bleeding was found to be most prevalent in the third trimester. Pocket depth of 4-5 mm was found to be highest in the second trimester. Pocket depth of 6 mm or more was restricted to the third trimester. Oral hygiene scores increased in tandem with gestational age. Conclusion: The majority had caries, which strongly suggests that the awareness of the pregnant women regarding their oral hygiene remains limited.

Interleukin-6 and Interferon-α Levels in Gingival Crevicular Fluid in HIV-1 Patients with Chronic Periodontitis / Niveles de Interleukin-6 e Interferon-α de Fluido Crevicular Gingival en Pacientes VIH-1 con Periodontitis Crónica

ABSTRACT: The influence of cytokine on the progression of chronic periodontitis in human immunodeficiency virus (HIV) patients is still controversial and poorly investigated. This study aimed to analyze and compare IL-6 and IFN-α levels in the gingival crevicular fluid of HIV-1-positive and HIV-1-negative patients with chronic periodontitis and different grades of tissue destruction and inflammation. Samples from the gingival crevicular sulcus were obtained from 35 HIV-1-positive individuals with chronic periodontitis and 35 seronegative patients with chronic periodontitis. Probing depth and clinical attachment level, as well as the results of the Enzyme-Linked Immunosorbent Assay for confirmation of patient diagnostics, were evaluated. Statistical analyses were performed using Student t, Mann-Whitney and Spearman tests. IL-6 levels were significantly lower, while IFN-α levels were significantly higher in HIV-1 patients. Clinical attachment level was directly associated with IFN-α levels in HIV-1 carriers, connected to probing depth in these patients. Clinical data in association with gingival crevicular fluid cytokine levels may reveal a localized immunological response pattern, which may contribute to the understanding of periodontitis pathogenesis in HIV-1 carriers.

RESUMEN: La influencia de la citocina en la progresión de la periodontitis crónica en pacientes con el virus de la inmunodeficiencia humana (VIH) sigue siendo controvertida y poco investigada. Este estudio tuvo como objetivo analizar y comparar los niveles de interleuquina-6 (IL6) e interferón-α (IFN-α) en el líquido crevicular gingival de pacientes VIH-1-positivos y VIH-1-negativos con periodontitis crónica y diferentes grados de destrucción e inflamación tisular. Se obtuvieron muestras del surco crevicular gingival de 35 individuos VIH-1 positivos con periodontitis crónica y 35 pacientes seronegativos con periodontitis crónica. Se evaluaron la profundidad de sondeo y el nivel de inserción clínica, así como los resultados del Ensayo Inmunoabsorbente Ligado a Enzimas para la confirmación del diagnóstico del paciente. Los análisis estadísticos se realizaron utilizando pruebas t de Student, Mann-Whitney y Spearman. Los niveles de IL-6 fueron significativamente más bajos, mientras que los niveles de IFN-a fueron significativamente más altos en los pacientes con VIH-1. El nivel de inserción clínica se asoció directamente con los niveles de IFN-α en los portadores del VIH1, conectados a la profundidad del sondaje en estos pacientes. Los datos clínicos en asociación con los niveles de citoquinas de los fluidos creviculares gingivales pueden revelar un patrón de respuesta inmunológica localizado, que puede contribuir a la comprensión de la patogénesis de la periodontitis en los portadores del VIH-1.

Infecções endodônticas persistentes: causas, diagnóstico e tratamento / Persistent endodontic infections: causes, diagnostic and treatment

Introdução: Microrganismos subsecivos de infecções endodônticas primárias ou secundárias são a causa das infecções persistentes ou refratárias. Objetivo: realizar uma revisão de literatura sobre as infecções endodônticas persistentes, descrevendo a microbiota mais comumente associada ao insucesso da terapia endodôntica, bem como ressaltar o diagnóstico e tratamento dessas infecções. Metodologia: Foram realizadas buscas bibliográficas eletrônicas utilizando base de dados como Pubmed, Lilacs e Bireme que abordassem o tema proposto no período de 2000 a 2016. Para tanto, foram utilizados os seguintes descritores de assunto na língua portuguesa: "Endodontia", "Infecção persistente", "Periodontite apical" e na língua inglesa: "Endodontics", "Persistent infection","Apical Periodontitis". Resultados: Os artigos selecionados foram lidos criteriosamente e mostraram que esses microrganismos resistem aos procedimentos intracanais de desinfecção, resultando em uma periodontite apical persistente, com ou sem sintomatologia clínica e radiográfica evidente. O diagnóstico e tratamento são dificultados devido à complexidade anatômica do sistema de canais radiculares e capacidade de resistência bacteriana e o tratamento envolve um tratamento endodôntico efetivo, com necessidade cirúrgica em alguns casos. Conclusão: A análise desses patógenos é crucial nas infecções refratárias, tornando-se necessário avançar nas pesquisas para a determinação de novas técnicas de desinfecção associadas a novas medicações que tornarão a Endodontia cada vez mais eficaz e com resultados ainda mais previsíveis

RESUMEN: Dentro de las patologías orales, la caries, enfermedad periodontal y pérdida de dientes, son las enfermedades más frecuentes en la población adulta, sin embargo, su prevalencia en pacientes embarazadas del tercer trimestre y puérperas hospitalizadas es un área poco investigada. Comparar la condición de salud oral de embarazadas del tercer trimestre y puérperas hospitalizadas en el Hospital Parroquial de San Bernardo entre los años 2015-2016, que utilizaron el programa de salud oral integral de la embarazada GES versus aquellas que no lo utilizaron. Se realizó un estudio de tipo transversal donde se evaluó a 321 pacientes, las cuales se encontraban hospitalizadas en el servicio de Ginecología y Obstetricia del Hospital Parroquial de San Bernardo. Se analizó la prevalencia de caries, enfermedad periodontal, piezas ausentes y COPD, utilizando el programa estadístico Stata 14.0 y Test chi-cuadrado, Mann Whitney, exacto de Fisher. La muestra quedó constituida por 293 pacientes, 236 (80,55 %) correspondían a pacientes que utilizaron el programa GES de la embarazada. El promedio de edad de las pacientes fue de 26 años, el nivel socio económico y el nivel educacional más prevalente fue el nivel C3 en el 42,3 % y media completa en un 37,8 %, respectivamente. Las embarazadas que utilizaron el programa GES, presentaron un componente C menor y un componente O mayor, cuya diferencia fue estadísticamente significativa, para el componente C y O del COPD (p=0,0001 y p=0,0089) respectivamente. El ser beneficiario GES es un factor protector de caries, con un OR de 0,33 valor p < 0,001 y un intervalo de confianza al 95 % de 0,18 - 0,61. Las pacientes evaluadas no presentaban diferencias en los parámetros periodontales estudiados, en cambio las pacientes GES si tenían un factor C menor que las no GES, en el COPD.

ABSTRACT: Dental caries, periodontitis and tooth loss are considered the most frequent oral conditions in the adult population. This is not an exception during pregnancy, where efforts have been made in Chile to improve women's oral health through the GES program initiative, developed in 2010. However, prevalence of these conditions is unknown for the Chilean pregnant and puerperal population. The aim of this study was to compare differences in the oral health condition of third trimester pregnant and puerperal women hospitalized in San Bernardo's Parochial Hospital during 2015-2016 with regards to the use of the GES program. A cross-sectional study was conducted in the Gynecology and Obstetrics Service of San Bernardo's Parochial Hospital, where 321 hospitalized third trimester pregnant and puerperal women received a thorough oral examination with a selfadministered questionnaire collecting data on sociodemographics, oral hygiene habits and frequency of dental visits. The prevalence of dental caries, periodontal disease and tooth loss were studied. Chi-square, Mann Whitney and Fisher's exact tests were conducted using the Stata 14.0 software. Two hundred and ninety three patients agreed to participate, with a mean age of 26, and 236 (80.55 %) were GES program users. A C3 socio-economic and educational level of (42.3 %) and a completed high school level (37.8 %) were the most frequent. Pregnant and puerperal women using the GES program presented statistically lower (p = 0.0001) and a higher restoration records (p = 0.0089) in the COPD index. The evaluated patients had a high COPD index and a high prevalence of periodontal disease. Being a GES user had an OR of 0.33 p value <0.001 and a 95 % confidence interval of 0.18 - 0.61. The evaluated patients did not present differences in periodontal parameters studied, whereas GES patients had a C factor lower than non-GES patients, in the COPD. The GES program could be a caries protective factor for third trimester pregnant and puerperal women hospitalized in San Bernardo's Parochial Hospital during2015-2016.

Análisis biomecánico en la marcha deportiva entre deportistas de iniciación y alto rendimiento / Biomechanical analysis in sports walk among beginners and high performance athletes

Introducción: La relación causa / efecto entre el embarazo y la enfermedad periodontal resulta muy contradictorio en la literatura. Algunos autores niegan que exista esta relación, mientras otros la afirman. Objetivo: Identificar la presencia de Enfermedad Periodontal en gestantes del primer y tercer trimestre, teniendo en cuenta la edad y la higiene bucal de las mismas. Métodos: La muestra estuvo integrada por 106 gestantes del primer y tercer trimestre del embarazo. Las mismas fueron reunidas de acuerdo a los siguientes grupos de edades: Adolescentes, adultas jóvenes y adultas de más de 35 años. A todas las gestantes de la muestra se les efectuó un examen estomatológico para diagnosticar las pacientes portadoras de Enfermedad Periodontal, las formas clínicas presentadas, así como evaluar la calidad de la higiene bucal. Resultados: Se comprobó que 36 de las gestantes eran portadoras de Enfermedad Periodontal: 34 presentaban gingivitis y dos periodontitis. La forma clínica más abundante fue la gingivitis fibro-edematosa. De las 36 gestantes enfermas, 33 eran adultas jóvenes y tres, mayores de 35 años. Ninguna de las adolescentes presentó EP. Del total de gestantes, 20 se encontraban en el primer trimestre y 16 en el tercero. De las 36 pacientes enfermas 29 presentaron higiene bucal deficiente para un 80,55 por ciento y sólo siete mostraban una higiene bucal eficiente para un 19,44 por ciento. Conclusiones: La Enfermedad Periodontal es frecuente entre las gestantes del primer y tercer trimestre a lo cual contribuye la mala higiene bucal, la edad, como también la elevación de las hormonas durante el embarazo(AU)

Introduction: The cause / effect relationship between pregnancy and periodontal disease is very contradictory in the literature. Some authors deny that this relationship exists, while others affirm it. Objective: To identify the presence of Periodontal Disease in first and third trimester pregnant women, taking into account their age and oral hygiene. Methods: The sample consisted of 106 pregnant women from the first and third trimesters of pregnancy. They were collected according to the following age groups: Adolescents, young adults and adults over 35 years of age. All the pregnant women in the sample underwent a stomatological examination to diagnose the patients carrying Periodontal Disease, the presented clinical forms, as well as to evaluate the quality of the oral hygiene. Results: It was found that 36 of the pregnant women were carriers of Periodontal Disease: 34 had gingivitis and two periodontitis. The most abundant clinical form was fibro-edematous gingivitis. Of the 36 pregnant women, 33 were young adults and three were over 35 years old. None of the adolescents presented EP. Of the total of pregnant women, 20 were in the first quarter and 16 in the third. Of the 36 sick patients, 29 had poor oral hygiene for 80.55 percent and only seven showed efficient oral hygiene for 19.44 percent. Conclusions: Periodontal disease is common among pregnant the first and third quarter which contributes to poor oral hygiene, age, as well as elevated hormones during pregnancy(AU)

Evaluation of Periodontal Status of Adjacent Teeth to Posterior Single- Tooth Implant during a One-Year Period after Restoration: A Cross- Sectional Study

Objective: To evaluate the periodontal status of teeth adjacent to the posterior single tooth implant during one year after restoration. Material and Methods: In this crosssectional study, 36 patients, which were systematically and had received the implant(s) of single posterior teeth over the past year were selected. The teeth adjacent to singleposterior tooth implants were evaluated regarding bleeding on probing, mobility, gingivitis and periodontal pockets during the follow up period of 3, 6 and 9 months under the supervision of two specialists. To investigate the relationship between periodontal statuses, the Chi-square test was used, and the Kruskal-Wallis test was used to assess statistical significance of periodontal indexes in the period under assessment. The p-value of less than 0.05 was considered significant. Results: There was no significant relationship between the variable of bleeding on probing, mobility, gingivitis and periodontal pocket in the studied distal and mesial teeth. Out of studied patients, after 9 months, only 11.1% had one of the periodontal problems, as a result, 88.9% of crowns replacement of single-posterior tooth does not make any periodontal damages to adjacent teeth. Conclusion: Crowns replacement of implant does not have any destructive impact on periodontal condition of adjacent teeth.

Knowledge, Attitudes and Practices of Doctors and Dental Surgeons in Bamako on the Relationship Between Periodontal Diseases and Chronic Non-Communicable Diseases

Objective: To assess the level of knowledge, attitudes and practices of doctors and dentists in Bamako on the relationship between chronic non-communicable diseases and periodontal diseases. Material and Methods: A cross-sectional study of 420 physicians and dental surgeons was conducted from March to August 2016. Data analysis involved descriptive statistics (frequency distribution). All statistical analyses were performed using the Epi Info 3.5.4 Software. Results: The male sex was the most represented with 58% for a sex ratio of 1.3. The most represented age group was 30-40 years old (48.8%) with an average age of 33 ± 8.2 years. General practitioners were the most represented in 93.6% of cases. Physicians with no knowledge of periodontal disease accounted for 60% of all cases, and all dental surgeons reported knowledge of chronic noncommunicable conditions in 100% of cases. Physicians and dental surgeons rated their knowledge levels of periodontal disease and chronic disease as inadequate in 98% and 90% of cases, respectively. Examination of the oral cavity by the doctors was "sometimes" carried out in 66% of the cases and the non-demand of the clinical signs of the gingival bleeding (64%) and dental migration (80.5%). They did not make recommendations on oral hygiene in 61.7% of cases. Conclusion: This study shows shortcomings among doctors and dentists in Bamako on the relationship between periodontal diseases and chronic non-communicable diseases. Capacity building and multidisciplinary collaboration are needed to support people's health.

Comparison between 940 nm Laser Diode and Topical 5% Potassium Nitrate for Tooth Desensitization. Randomized Controlled Clinical trial / Comparación entre el láser diodo de 940 nm y el nitrato de potasio tópico al 5% para la desensibilización dental. Estudio clínico controlado aleatorizado

Objetivo: Comparar la efectividad de las terapias de sensibilización dental que usan láser diodo 940 nm y nitrato de potasio en pacientes con síntomas de hipersensibilidad dental (HD). Métodos: Este ensayo clínico aleatorizado incluyó 30 pacientes quienes habían recibido previamente terapia periodontal básica y presentaban recesiones gingivales clases I y II (Miller 1985) con síntomas de HD. La muestra fue asignada aleatoriamente a los dos grupos. Al primero (n=15) le fue aplicado láser 940 nm por 90 segundos en la superficie de la recesión, y se les suministró un tubo de glicerina para ser aplicado diariamente y evitar la generación de sesgos. El segundo grupo (n=15) recibió láser inactive como placebo y se le suministró un gel desensibilizante que contenía nitrato de potasio 0,5 g para aplicar dos veces al día durante 14 días. Se realizaron controles a los 15 minutos, 8 días, 15 días y 4 semanas. Los datos obtenidos se registraron en una table en Excel. Se emplearon U de Mann Whitney U y t Student para comparar los grupos (p=0,05). Resultados: Todos los pacientes del estudio mostraron reducción de la HD, diferencias que fueron estadísticamente significativas (p<0,01) entre los dos grupos intervenidos. Conclusiones: Ambos, el láser diodo y el nitrato fueron efectivos en el manejo posterior a la terapia periodontal para el manejo de la HD. Sin embargo, las diferencias fueron mayores para el grupo de terapia con láser.

Purpose: To compare the effectiveness of two dental desensitization therapies, 940nm laser diode and potassium nitrate, in patients with dental hypersensitivity (DH) symptoms. Methods: This randomized clinical trial included 30 patients who initially underwent basic periodontal therapy and presented gingival recessions Class I and II (Miller 1985) with symptoms of DH. Subjects were randomly assigned into two groups. The first group (n = 15) received laser 940 nm application for 90 seconds on the surface of the recession and were given a tube of glycerin to be applied daily in order to avoid generating bias. Patients in the second group (n = 15) were exposed to inactive laser simulating the actual application of the laser, and they were given a desensitizing gel containing 0.5 g of potassium nitrate to be applied twice daily during 14 days. Controls were carried out at 15 minutes, 8 days, 15 days, and 4 weeks. Data obtained were filled out in an Excel table. For comparison between groups the Mann Whitney U and t student tests were used (p=0.05). Results: All patients involve in the study experienced reduction in DH (p<0.01) and differences between the two interventions performed. Conclusions: Laser and nitrate therapies were effective to manage DH after basic periodontal therapy. However, a statistically significant higher sensitivity reduction was observed in laser therapy group.
