Use of Ionized Monocalcium phosphate and enameline derivatives to reduce dentin hypersensitivity after periondontal therapy / Uso de Fostato Monocálcio y derivados en Enamelina para reducir la hipersensibilidad dentaria después de terapia periodontal

Abstract This study aimed to evaluate the effectiveness of using an ionized monocalcium phosphate and enamelin derivatives (IMP+ED) based mouthwash for the treatment of dentin hypersensitivity (DH) after scaling and root planing (SRP). 47 patients who reported DH after SRP treatment were included in this prospective cohort study. The Schiff Cold Air Sensitivity Scale (SCASS) was applied to classify their degree of pain in mild, moderate or intense at two times: after SRP (T0), and after one month of using a IMP+ED-based mouthwash (T1). The McNemar-Bowker test was used to compare the correlated proportions between both times (p<0.05). After the SRP therapy (T0), all the sample members reported pain distributed in the following manner: 12.8% were mild, 27.6% moderate, and 59.6% intense. At one month since treatment and with the use of the IMP+ED-based mouthwash (T1), the distribution of pain levels changed to 83% mild, 12.8% moderate, and 4.3% intense, this change was statistically significant (p<0.001). IMP+ED-based mouthwash produces a positive effect in reducing painful responses caused by exposure of the dentin tubules to the oral environment after SRP therapy.

Resumen El objetivo de este estudio fue evaluar la efectividad de un enjuague bucal a base de fosfato monocálcico ionizado y derivados de enamelina (FCI+DE) para el tratamiento de hipersensibilidad dentinaria (HD) posterior al tratamiento de raspado y alisado radicular (RAR). 47 pacientes que reportaron tener HD posterior al tratamiento de RAR fueron incluidos en este estudio prospectivo de cohorte. Con el fin de clasificar la HD de los pacientes en leve, moderada o intensa se utilizó la Escala de Sensiblidad al Aire Frío de Schiff (ESAFS). Los pacientes fueron evaluados después del tratamiento de RAR (T0) y posterior al uso de un enjuague bucal basado en FCI+DE (T1). Para comparar las proporciones correlacionadas se utilizó la prueba de McNemar-Bowker (p<0.05). La distribución del dolor de los pacientes posterior al tratamiento de RAR (T0) fue la siguiente: 12.8% fueron leves, 27.6% moderado, and 59.6% intenso. Un mes después del uso del enjuague buccal basado en FCI+DE (T1) la distribución en los niveles de dolor cambio a 83% leve, 12.8% moderado, and 4.3% intenso, este cambio fue estadísticamente significativo (p<0.001). El uso del enjuague bucal basado en FCI+DE produce una reducción significativa a la respuesta de dolor causada por la exposición de la dentina al ambiente oral como consecuencia del tratamiento de RAR.

Efectividad de antimicrobianos como coadyuvantes del raspado y alisado radicular en el tratamiento de la periodontitis del adulto

Fundamento: existen escasos estudios que evalúen la aplicación subgingival de antimicrobianos en el tratamiento de la periodontitis del adulto. Objetivo: evaluar la efectividad de antimicrobianos como coadyuvantes del raspado y alisado radicular en el tratamiento de la periodontitis leve y moderada del adulto. Métodos: estudio cuasiexperimental de intervención terapéutica, realizado en la Clínica Estomatológica de Santiago de Cuba, entre noviembre 2018 y septiembre 2021, sobre 144 pacientes con diagnóstico de periodontitis crónica leve y moderada. Mediante el método probabilístico aleatorio simple, se conformaron tres grupos con 48 integrantes, de forma voluntaria. El grupo control tratado con el raspado y alisado radicular y dos grupos de estudio en que, además, se aplicó una concentración subgingival de tetraciclina y azitromicina, respectivamente. Los pacientes fueron examinados y evaluados a los siete días, al mes y tres meses. Se empleó el análisis de varianza ANOVA para evaluar la igualdad de medias y la prueba ji-cuadrado para la efectividad de curación con un 95 % de confiabilidad. Resultados: hubo reducción de profundidad de sondaje y mayor ganancia de inserción clínica en los tres grupos, pero a favor de los grupos de estudio. Todas las terapias fueron efectivas, pero obtuvo mayor curación el grupo dos (RAR + Tetraciclina) con 97,9 %. Conclusiones: las aplicaciones subgingivales de tetraciclina y azitromicina resultaron efectivas como coadyuvantes del raspado y alisado radicular en el tratamiento de la periodontitis leve y moderada del adulto; con la tetraciclina se logró mayor mejoramiento de parámetros clínicos, disminución de profundidad de sondaje, ganancia de inserción clínica y menor tiempo de curación.

Background: there are few studies that evaluate the subgingival application of antimicrobials in adult periodontitis. Objective: to evaluate the effectiveness of antimicrobials as contributing for scaling and root planing in the treatment of mild and moderate periodontitis in adults. Methods: quasi-experimental study of therapeutic intervention, carried out at the Santiago de Cuba Stomatological Clinic, between November 2018 and September 2021, on 144 patients diagnosed with mild and moderate chronic periodontitis. Using the simple random probabilistic method, three groups with 48 members were formed voluntarily. The control group treated with scaling and root planing and two study groups in which, in addition, a subgingival concentration of tetracycline and azithromycin, respectively, was applied. The patients were examined and evaluated at seven days, one month and three months. ANOVA analysis of variance was used to evaluate the equality of means and the chi-square test for the effectiveness of healing with 95% reliability. Results: there was a reduction in probing depth and greater gain in clinical attachment in the three groups, but in favor of the study groups. All therapies were effective, but group two (RAR + Tetracycline) obtained a greater cure with 97.9%. Conclusions: subgingival applications of tetracycline and azithromycin were effective as adjuvants for scaling and root planing in mild and moderate periodontitis in adults; Tetracycline achieved greater improvement in clinical parameters, decreased probing depth, gain in clinical attachment, and shorter healing time.

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.

Uso de probióticos como adición al tratamiento periodontal no quirúrgico en pacientes con periodontitis / Use of probiotics as an adjunctive therapy to non-surgical periodontal treatment in patients with periodontitis

RESUMEN Introducción: El tratamiento periodontal no quirúrgico corresponde a la terapia estándar para la periodontitis crónica. En este contexto, se ha propuesto que el uso de probióticos orales como complemento al tratamiento estándar podría mejorar los resultados obtenidos clínicamente, sin embargo no existe claridad respecto a su efectividad. Métodos: Se realizó una búsqueda en Epistemonikos: base de datos de revisiones sistemáticas en salud mantenida mediante el cribado de múltiples fuentes de información, la cuál incluye MEDLINE, EMBASE, Cochrane, entre otras. Se extrajeron los datos desde las revisiones identificadas y un análisis de los datos de los estudios primarios. Se realizó un metanálisis y se preparó una tabla de resumen de los resultados utilizando el método GRADE. Resultados y conclusiones: Se Identificaron seis revisiones sistemáticas que en conjunto incluyeron 14 estudios primarios, todos correspondientes a ensayos aleatorizados. De los resultados analizados se concluye que el uso de probióticos orales como complemento al tratamiento no quirúrgico de periodontitis crónica probablemente resulta en nula o poca diferencia en la reducción de la profundidad de sondaje, el sangrado al sondaje y una ganancia de nivel de inserción clínico en los sitios afectados. Por otro lado, no se encontraron estudios que evaluaran el riesgo de presentar halitosis en pacientes sometidos a terapia periodontal no quirúrgica con adición de probióticos.

ABSTRACT: Introduction: Non-surgical periodontal treatment is the standard treatment to chronic periodontitis. It has been proposed that the use of oral probiotics as an adjunctive therapy may improve clinical outcomes, however there is no clarity regarding its effectiveness. Methods: We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. Results and conclusions: We identified six systematic reviews including 14 studies overall, of which all were randomized trials. We concluded that the addition of probiotics to non-surgical periodontal treatment probably results in little or no difference in probing depth reduction, clinical attachment level gain and reduction in bleeding on probing. No studies were found evaluating halitosis in patients undergoing non-surgical periodontal treatment with the addition of probiotics.

Influence of mechanical debridement on the subgingival microbiome in chronic periodontitis / 口腔疾病防治

Objective@# To investigate the influence of mechanical debridement on the subgingival microbiome in chronic periodontitis by 16S rRNA high-throughput sequencing.@*Methods@#Patients with generalized moderate to severe chronic periodontitis were recruited into this study and received oral hygiene instruction and supragingival scaling. One week later, they received ultrasonic and manual subgingival scaling and root planning. Clinical parameters were recorded and subgingival plaques were sampled at baseline and 3 months and 6 months after treatment. The comprehensive profiles of the subgingival microbiome were analyzed by sequencing the V3-4 region of 16S rRNA with the Illumina MiSeq platform.@*Results @#Alpha diversity analysis showed that the richness and diversity of the subgingival community were consistent before and after treatment, but a significant difference in community structure was detected only between baseline and month 3 by principal coordinates analysis (PCoA). After 3 months, the clinical parameter as probing depth (PD) decreased significantly and the relative abundances of the genera related to periodontitis such as Porphyromonas, Treponema, Tannerella, and Filifactor decreased significantly. Meanwhile, the relative abundances of the genera associated with periodontal health increased, such as Capnocytophaga, Kingella. Six months later, however, less genera related to periodontitis decreased significantly from the baseline level, such as Filifactor. PD decreased significantly compared with baseline, but increased significantly compared with 3 months after treatment. @* Conclusion@#Mechanical debridement alone could relieve periodontal inflammation and balance microbial dysbiosis and the greater efficacy occurred 3 months after treatment.

A Comparative Clinical, Microbiological and Biochemical Evaluation of Guided Periodontal Pocket Recolonisation (GPR) using Synbiotics as an Adjunct to Scaling and Root Planing in Patients with Chronic Periodontitis: A Pilot Project

Background: With increase in the resistance to antibiotics, the paradigm of periodontal treatment in recent years is slowly shifting from specific bacteria elimination to altering bacterial ecology by probiotics. With this objective in mind, the present study was carried out to assess the use of a symbiotic preparation as a guided pocket recolonisation (GPR) procedure in patients with chronic periodontal disease. Materials and methods: Total 180 patients with chronic periodontitis with presence of true periodontal pockets; 4 mm-6 mm in depth involving minimum 3 or more quadrants were selected and divided into 3 groups wherein the first group only scaling and root planing was done without GPR application; in the 2nd group, GPR was carried out as a single application following SRP and in the 3rd group, multiple applications of GPR with SRP was done. Clinical measurements; microbiological analysis of periodontal pathogens by anaerobic culture and biochemical assessment of alkaline phosphatase and interleukin-6 using ELISA and spectrophotometry was carried out at baseline, 3 and 6 months respectively. Results: All the 3 groups showed significant changes in clinical (p<0.05) as well as in microbiological and biochemical parameters (p<0.05) within the groups. Intergroup comparisons revealed significant changes in group 2 and 3 with biochemical parameters. Positive correlation was observed with clinical parameters and alkaline phosphatase levels and P. intermedia counts in group 1 and 3. Conclusion: Within the limitations of the present study, it could be concluded that symbiotic therapy may have some additional benefit to Scaling and root planing.

OBJECTIVE@#To evaluate the clinical efficacy of ultrasound subgingival scaling combined with manual root planing for treatment of chronic periodontitis in elderly patients.@*METHODS@#Forty elderly patients with chronic periodontitis were randomly divided into test group for treatment with ultrasound and Gracey subgingival curette for subgingival scaling combined with manual root planing and control group treated with ultrasound subgingival curette scaling (=20). We compared plaque index (PLI), bleeding index (BI), probing depth (PD), and attachment loss (AL) between the two groups before and at 6 weeks and 12 weeks after the treatment.@*RESULTS@#After periodontal treatment, PLI, BI, PD and AL all decreased significantly in both groups compared with the levels before the treatment ( < 0.05). The patients in the test group showed significantly more obvious decrease of PD and AL than those in the control group ( < 0.05), but the reduction of PLI and BI was comparable between the two groups (>0.05).@*CONCLUSIONS@#Ultrasound subgingival scaling combined with manual root planing produces better therapeutic effect than ultrasonic subgingival scaling alone for treatment of chronic periodontitis in elderly patients.

Gingival crevicular fluid response to protocols of non-surgical periodontal therapy: A longitudinal evaluation

Context and Aim: Gingival crevicular fluid (GCF) volume reflects the level of periodontal inflammation. This secondary analysis aimed to evaluate the GCF volume in patients submitted to non-surgical periodontal therapies under a split-mouth design. Materials and Methods: GCF volume of 25 participants (47.24 ± 6.47 years) with moderate-to-severe chronic periodontitis was collected at Days 0, 30, 60, 90, 120, 270, and 450. The participants were submitted to three different non-surgical therapies randomly assigned per quadrant [GI: supragingival control (Supra) as only intervention (one quadrant); GII: Supra plus scaling and root planing (SRP) on Day 0 (two quadrants); GIII: Supra on Day 0 and SRP 30 days later (one quadrant)]. During treatment (0–60 days) and maintenance (90–450 days) participants were submitted to supragingival plaque control reinforcements. GCF volumes were analyzed after logarithmic transformation (log10) and linear models were used for intra- and inter-group comparisons, considering the data dependence. Results: Baseline GCF volumes were similar between groups (GI: 0.39 ± 0.22 μl; GII: 0.42 ± 0.26 μl; GIII: 0.41 ± 0.14 μl;P > 0.05). At Day 60, GCF volumes were significantly reduced (GI: 0.20 ± 0.13 μl; GII: 0.18 ± 0.11 μl; GIII: 0.22 ± 0.13 μl; P < 0.001), without inter-groups differences. These results were maintained along maintenance period (P > 0.05). Even in sites bleeding on probing (BOP) + the means of GCF volume did not differ between groups (P > 0.05). Conclusions: All therapies determined reductions on the GCF volume along time. Supragingival plaque control modulated the subgingival area during the study, reinforcing the importance of this control over the subgingival inflammatory response.

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.

Expression of Osteopontin mRNA During Periodontal Healing Following Scaling and Root Planing

Objective: To analyze osteopontin mRNA expression levels in subjects with periodontitis prior to (baseline) and 7, 14, and 28 days following scaling and root planing (SRP). Material and Methods: Gingival crevicular fluid was collected as clinical samples from four subjects with periodontitis (pocket depth, 4-5 mm) aged 35-54 years old as well as from three healthy subjects (controls). The osteopontin mRNA expression levels were measured by quantitative real-time polymerase chain reaction. Spearman's rank correlation between osteopontin levels in gingival crevicular fluid and the modified gingival index (MGI) was also performed. Results: The Wilcoxon signed-rank test showed no significant difference in osteopontin mRNA expression levels between baseline and 28 days following SRP (p=0.068). The Friedman test showed no significant difference in osteopontin mRNA expression levels between baseline and following SRP (7, 14, or 28 days) (p>0.05). Spearman's rank correlation showed no significant correlation between osteopontin mRNA expression levels and MGI (r=0.087; p=0.749). Conclusion: Following SRP of periodontal tissue, there was a decreasing trend in osteopontin mRNA expression; however, this finding was not statistically significant. Nevertheless, osteopontin can be used as a biomarker to monitor the healing process; however, further studies are required to clarify our results.

Terapia periodontal de suporte em paciente com periodontite agressiva generalizada: acompanhamento clínico e radiográfico de 13 anos / Periodontal maintenance therapy in patient with generalized aggessive periodontitis: clinical and radiographic following by 13 years

A terapia periodontal de suporte (TPS) tem como objetivo principal a manutenção dos resultados obtidos durante o tratamento periodontal ativo, sendo a forma mais previsível de controlar a doença periodontal. Essa extensão do tratamento periodontal, pode ocorrer em intervalos de tempo que variam de acordo com a severidade da doença, condição sistêmica do indivíduo, idade, fatores de risco, entre outros. A TPS contribui para a redução da perda dentária e recorrência da doença periodontal, além de possibilitar o diagnóstico de outras doenças bucais. Durante essa etapa, é possível traçar o perfil do paciente, identificar suas dificuldades e estabelecer condutas educativas, preventivas e terapêuticas necessárias para o controle do biofilme e da doença periodontal. Assim, o periodontista deve conscientizar o paciente sobre a importância da TPS, sendo que, a adesão ao tratamento é fundamental para a manutenção da saúde dos tecidos periodontais a longo prazo. O presente relato de caso clínico, demonstra o sucesso da TPS em paciente jovem acometida por periodontite agressiva generalizada. Após a realização da terapia periodontal não cirúrgica, a paciente foi inserida em um programa de manutenção periodontal, há 13 anos atrás, no qual participa ativamente até o presente momento. (AU)

The main objective of the periodontal maintenance therapy (PMT) is to maintain the results achieved during the active periodontal therapy, being the most predictable way of controlling the periodontal disease. This extension of the periodontal treatment may occur at different times, varying according to the aggressiveness of the disease, general health condition of the subject, age and risk factors, among others. The PMT contributes to the reduction of dental loss and prevents the reoccurrence of the periodontal disease, while also allowing the diagnose of other diseases of the mouth. During this phase it is possible to trace the patient's profile, identifying the difficulties and stablishing educational, preventive and therapeutic practices to control oral biofilm and periodontal disease. Thus, the periodontist must raise the patient's awareness to the importance of the PMT, as the patient compliance to the treatment is essential for the long term preservation of the periodontal tissue health. The clinical case here described demonstrates the success of the PMT performed on a young female patient afflicted with generalized aggressive periodontitis. After having performed the non-surgical periodontal therapy, the patient entered a periodontal maintenance program 13 years ago, in which she has been actively participating until the present time.(AU)

Scaling and Root Planing Effect to mRNA Expression of Matrix Metalloproteinase-9 and Periodontal Clinical Parameters on Chronic Periodontitis

Abstract Objective: To evaluate the relationship between the mRNA transcription level of Matrix Metalloproteinase-9 (MMP-9) and the selected clinical periodontal healing at one month of scaling and root planing. Material and Methods: A total of six chronic periodontitis patients and one periodontally healthy subject were recruited. The gingival crevicular fluid was collected from all subjects, and the expression level of MMP-9 mRNA was measured by quantitative real-time PCR. Pocket depth, papilla bleeding index, and clinical attachment loss were measured on day 1 at baseline and day 30. Scaling and root planing was performed on day 1. Data were analyzed using SPSS 22.0 software Results: In comparison to the control, periodontal clinical parameters in the treatment group were significantly reduced after scaling and root planing. MMP-9 mRNA expression did not show a significant change after the 30th day. A weak correlation was noted between the MMP-9 mRNA transcription level and the changed PBI measurement Conclusion: Scaling and root planing is clinically effective for chronic periodontitis with a 4-6 mm pocket, whereas the expression of MMP-9 mRNA was not altered. Further studies with a more extended observation period are needed to confirm or reject the present findings.

Efect of Anaheal (Bromelain) Drug on the Periodontal Clinical Indices in Nonsurgical Periodontal Treatment of Patients with Chronic Periodontitis

Objective: To evaluate the effect of Anaheal (Bromelain) drug on the periodontal clinical indices in nonsurgical periodontal treatment of patients with chronic periodontitis. Material and Methods: In this double blind clinical trial, 80 patients with chronic moderate periodontitis and a healthy systemic status were chosen, and divided into two 40-subject groups. Thereafter, the standard treatment of periodontitis including scaling and root planning in one session by the unit operator was performed for all patients. Eventually, one group of the patients was administered Bromelain medication (500-mg capsule twice a day) one hour before food, while the other group was given placebo. Four and eight weeks after the treatment, the clinical periodontal indicators were measured and recorded in both groups. The data were assessed using descriptive statistics and analytical test methods (Mann-U-Whitney and Chi-square). P value less than 0.05 was considered statistically significant. Results: Gingival index, probing depth and plaque index before the treatment were similar in both groups (Anaheal and placebo). However, four and eight weeks after the treatment, the three studied indices were significantly lower in the Anaheal group as compared to the placebo (p<0.05). The index of bleeding on probing was also similar before the treatment and four weeks after the treatment in both groups. However, eight weeks after the treatment, this index was significantly lower in the Anaheal group as compared to the placebo group (p<0.05). Conclusion: Administration of oral Anaheal medication after nonsurgical periodontal treatments reduced all the clinical periodontal indices among patients with chronic periodontitis as compared to the control group. Therefore, it can be a suitable substitute for the common oral industrial antibiotics.

Intraosseous anesthesia using a computer-controlled system during non-surgical periodontal therapy (root planing): Two case reports

Local anesthesia is administered to control pain, but it may induce fear and anxiety. Root planing is a non-surgical periodontal therapy; however, when it is performed in an extensive manner, some tissue removal is inevitable. Notably, this removal may be so painful that local anesthesia is required to be administered to the area scheduled for the treatment. Although patients tend to accept root planing easily, they frequently express a fear of local anesthesia. Intraosseous anesthesia (IA) is an intraosseous injection technique, whereby local anesthetic is injected into the cancellous bone supporting the teeth. A computer-controlled IA system (CIAS) exhibits multiple benefits, such as less painful anesthesia, reduced soft tissue numbness, and the provision of palatal or lingual, as well as buccal, anesthesia via single needle penetration. In this report, we present two cases of root planing that were performed under local anesthesia, using a CIAS.

Clinical effects of additional use of erythritol powder air polishing device on non-surgical periodontal treatment in moderate chronic periodontitis

PURPOSE: The purpose of this study was to evaluate the clinical effects of erythritol powder air polishing device (EPAP) in addition to scaling and root planing (SRP) in non-surgical periodontal treatment in moderate chronic periodontitis patients. MATERIALS AND METHODS: Clinical evaluation was performed at 21 sites treated with SRP (control) and 21 sites treated with the addition of SRP+EPAP (test). All examinations were performed before treatment, 1 month after treatment, and 3 months after treatment. Depth of the periodontal pocket, gingival recession, clinical attachment level, plaque index, and bleeding of probing were measured as clinical parameters. RESULTS: In both test and control groups, there was a significant decrease in the depth of the periodontal pocket, plaque index, bleeding of probing, increased gingival recession, and gain of clinical attachment level at 1 month and 3 months after treatment. However, there was no significant clinical difference between the test group and the control group. Clinical result was improved after 1 month compared to the baseline; in contrast, results at 3 months after treatment were worse than at 1 month after treatment. CONCLUSION: In this study, we cannot suggest that SRP + EPAP is clinically more effective than SRP alone as non-surgical periodontal treatments. Periodic periodontal therapy, at intervals of at least every three months, is important for sustaining effects of this treatment.

Clinical and microbiological effects of the supplementary use of an erythritol powder air-polishing device in non-surgical periodontal therapy: a randomized clinical trial

PURPOSE: This study was undertaken to evaluate the clinical and microbiological effects of an erythritol powder air-polishing device (EPAP) as a supplement to scaling and root planing (SRP) therapy in patients with moderate chronic periodontitis. METHODS: Clinical and microbiological evaluations were performed at 21 sites treated with SRP (control) and 21 sites treated with SRP+EPAP (test). All examinations were performed before treatment, 1 month after treatment, and 3 months after treatment. RESULTS: There were no significant clinical differences between the test group and the control group. Microbiological analysis revealed that the relative expression level of Porphyromonas gingivalis was significantly lower in the test group than in the control group at 1 month after treatment. Clinical and microbiological results showed improvements at 1 month compared to baseline; in contrast, the results at 3 months after treatment were worse than those at 1 month after treatment. CONCLUSIONS: In this study, both SRP and SRP+EPAP were clinically and microbiologically effective as non-surgical periodontal treatments. In particular, the SRP+EPAP group showed an antimicrobial effect on P. gingivalis, a keystone bacterium associated with the onset of chronic periodontitis, in a short-term period. Periodic periodontal therapy, at intervals of at least every 3 months, is important for sustaining the microbiological effects of this treatment.

Eficacia de la azitromicina asociada al raspado y alisado radicular en periodontitis crónica / Efficacy of azithromycin associated with scaling and root planing in chronic periodontitis

RESUMEN: Objetivo: evaluar la eficacia de la azitromicina asociada al RAR asociada al (raspado y alisado radicular) en pacientes con periodontitis crónica. Material y método: El presente ensayo clínico paralelo aleatorizado, controlado y triple ciego, se desarrolló en la Clínica Estomatológica de la Universidad Católica Los Ángeles de Chimbote (Trujillo, Perú), entre marzo y diciembre de 2015. Participaron 30 pacientes adultos, distribuidos aleatoriamente en 2 grupos, designados con las letras A y B, de 15 integrantes cada uno. Cada paciente fue evaluado periodontalmente antes de realizarle el raspado y alisado radicular y optimización de las técnicas de higiene. A los pacientes del grupo A se les indicó tratamiento antibiótico con Azitromicina 500 mg por vía oral cada 24 horas durante 3 días y al grupo B se les indicó un placebo con las mismas características físicas del antibiótico escogido. Los pacientes fueron evaluados a los 3, 4 y 5 meses. La eficacia fue evaluada mediante el test T de Student para comparación de medias, considerando un nivel de significancia para los valores de p<0,05. Resultados: Se encontró que ambos grupos lograron mejorar la profundidad de sondaje y el nivel de inserción clínica sin embargo no presentaron diferencias estadísticamente significativas entre ellos. Conclusión: La azitromicina asociada al RAR no es eficaz como terapia coadyuvante en pacientes con periodontitis crónica.

ABSTRACT: Objective: To evaluate the efficacy of azithromycin associated with the RAR (scaling and root planing) in patients with chronic periodontitis. Material and Methods: This clinical trial parallel randomized, controlled, triple blind, was developed in the Stomatology Clinic of the Catholic University Los Angeles of Chimbote (Trujillo, Peru), between March and December 2015. The participants were 30 adult patients randomized 2 groups, designated by the letters A and B of 15 members each. Each patient was evaluated periodontally before Give you the scaling and root planing and optimization hygiene techniques. Patients in group A, were prescribed antibiotic treatment with azithromycin 500 mg orally every 24 hours for 3 days. While, group B were prescribed a placebo with the same physical characteristics of the antibiotic chosen. Patients were evaluated at 3, 4 and 5 months. The efficacy was evaluated using the Student t test to compare means, considering a level of significance for the values of p <0.05. Results: It was found that both groups were able to improve probing depth and clinical attachment level however no statistically significant differences between them. Conclusion: Azithromycin associated with the RAR is not effective as adjunctive therapy in patients with chronic periodontitis.
