Role of circulating microparticles and cytokines in periodontitis associated with diabetes.

Background: Periodontitis is a chronic inflammatory condition that affects the supporting tissues of the teeth, and can lead to serious complications such as tooth loss and systemic health problems, including diabetes, which have a bidirectional relationship with periodontitis. Circulating microparticles originate from different cell types after stimuli such as activation or apoptosis. Interleukins are related to processes in the regulation of the immune response, inflammation, and cell growth. This study aimed to evaluate circulating microparticles as well as interleukins in the plasma, at baseline and 1 month after the end of the non-surgical periodontal treatment. Methods: Samples were collected from 45 patients, with moderate to severe periodontitis with diabetes (N = 25) and without diabetes (N = 20). Microparticles were evaluated in the platelet-poor plasma by flow cytometer. Cytokine levels were evaluated by the enzyme immunoabsorption assay (ELISA). Results: Higher levels of the pro-inflammatory cytokines were found in the group with diabetes compared to the non-diabetic group both at baseline and 1 month after the end of the treatment. A higher IL-6/IL-10 ratio was found in patients with diabetes compared to the group without diabetes at T0 and T1, whereas an increased IFN-γ/IL-10 ratio was only found at T1 in patients with diabetes in comparison to the group without diabetes. In the group with diabetes, it was verified positive correlations between IL-10 and IL-6 or IFN-γ and a negative correlation between IL-6 and PMP, at T0; in contrast, in the T1, negative correlations were found between TNF-α and IL-10 or PMP. Besides, at T0, it was evidenced positive correlations both between circulating TNF-α and IL-6, and IL-10 and EMP, as well as a negative correlation between IL-10 and PMP in the group with diabetes. In addition, it was observed in T1 positive correlations between levels of TNF-α and IL-6, IFN-γ, or IL-10, and between PMP and IFN-γ, and between EMP and IL-6, TNF-α and IFN-γ in this group. Conclusion: The results suggest a modulatory effect of the periodontitis associated with diabetes, as well as the periodontal treatment, in the systemic inflammatory status of the participants of the study.

The Efficacy of Topical or Systemic Antibiotics as Adjuvants to Non-Surgical Periodontal Treatment in Diabetic Patients: A Systematic Review and Meta-Analysis of Randomized Clinical Trials.

Background: Periodontitis and diabetes mellitus (DM) exhibit a bidirectional relationship and are globally significant systemic chronic conditions. The utilization of antibiotics alongside non-surgical periodontal treatment (NSPT) has been a subject of investigation in numerous clinical studies involving human subjects. Thus, the objective of this systematic review is to address the following question: "What is the efficacy of scaling and root planing (SRP) associated with antimicrobials in patients with type 2 DM and periodontitis?". Methods: A systematic review of the literature was conducted encompassing databases such as MEDLINE/PubMed, Scopus, and Web of Science up to July 2024. Additionally, alerts were configured to capture studies published from the initial search until manuscript submission. Randomized clinical trials assessing clinical periodontal parameters in DM patients undergoing SRP and receiving either topical or systemic antibiotics were compared against a control group (SRP only). Two investigators independently screened articles, extracted data, and evaluated their quality. The selection process, study characteristics, risk of bias, impact of antibiotics on clinical parameters, and certainty of evidence were elucidated in both textual and tabular formats. Meta-analysis was performed separately with forest plots generated for treatment modalities, period of evaluation, and type of antibiotics used. Results: Following the analysis of abstracts and full articles, a total of 30 randomized clinical trials were incorporated into this review, comprising 9 studies on the association of topical antibiotics and 21 studies on systemic antibiotic administration. The principal periodontal parameters assessed included probing pocket depth (PPD), clinical attachment level (CAL), plaque index (PI), and bleeding on probing (BoP). Conclusions: Analysis of the results led to the conclusion that adjunctive periodontal treatment with either topical or systemic antibiotics confers subtle clinical benefits. Nevertheless, owing to the heightened emergence of resistant bacteria and potential side effects, the use of antibiotic therapy in periodontal treatment should be judiciously administered.

Comparações clínica e radiográfica de duas técnicas de aplicação do laser de baixa potência como adjuvante à terapia periodontal básica em pacientes com periodontite - um ensaio clínico controlado e randomizado / Clinical and radiographic comparisons of two low-power laser application techniques as an adjunct to basic periodontal therapy in patients with periodontitis - a randomized controlled clinical trial

Objetivo: Avaliar e comparar duas técnicas de aplicação do laser de baixa potência ­ transgengival (LBPT) e intrasulcular (LBPI) ­ utilizado na Fotobiomodulação como adjuvante à TPB em pacientes com periodontite. Metodologia: Trata-se de um ensaio clínico, randomizado, boca dividida e duplo cego, no qual foram selecionados, de cada paciente, 3 sítios periodontais doentes, em diferentes quadrantes, para um dos três grupos de tratamento: grupo RAR (grupo controle), grupo RAR + LBPT (teste 1) e grupo RAR + LBPI (teste 2). A terapia com laser de baixa potência nos grupos teste foi realizada em três momentos, sendo 48 horas, 7 e 14 dias após a finalização da RAR de boca completa. Os parâmetros clínicos de profundidade à sondagem (PS), nível clínico de inserção (NIC) e sangramento à sondagem (SS) foram avaliados antes do tratamento (T0), e após 3 (T1) e 6 meses (T2). Além disso, radiografias periapicais padronizadas foram usadas para medir e comparar a densidade óssea radiográfica 6 meses após conclusão do tratamento. Foram realizados o teste ANOVA para medidas repetidas para as variáveis quantitativas e o teste qui-quadrado para a variável categórica utilizando um nível de significância ou p < 0,05 e intervalos de confiança de 95%. Resultados: Reduções estatisticamente significativas de PS (p < 0,001) e NIC (p < 0,001) foram observadas nos três grupos de tratamento em 3 e 6 meses de acompanhamento em comparação ao baseline, sem diferenças significativas entre os grupos. Nenhuma diferença significativa foi encontrada no sangramento à sondagem em 3 e 6 meses e na densidade óssea radiográfica em 6 meses de acompanhamento. Conclusão: Os resultados mostraram que, comparado à TPB isolada, a fotobiomodulação adjuvante não trouxe benefícios adicionais, independentemente da técnica de aplicação do laser utilizada (AU).

Aim: To assess and compare two techniques of low-level laser application - transgingival (LLLTT) and intrasulcular (LLLTI) - used in Photobiomodulation as an adjunct to BPT in patients with periodontitis. Methods: This is a randomized, split-mouth, double-blind clinical trial where, from each patient, 3 diseased periodontal sites in different quadrants were selected for one of three treatment groups: SRP group (control group), SRP + LLLTT group (test 1), and SRP + LLLTI group (test 2). Low-level laser therapy in the test groups was performed at three time points, 48 hours, 7 and 14 days after completing full-mouth SRP. Clinical parameters of probing depth (PD), clinical attachment level (CAL), and bleeding on probing (BOP) were assessed before treatment (T0), and at 3 months (T1) and 6 months (T2). Additionally, standardized periapical radiographs were used to measure and compare radiographic bone density 6 months after treatment completion. Repeated-measures ANOVA was conducted for quantitative variables, and the chi-square test was used for the categorical variable, with a significance level of p < 0.05 and 95% confidence intervals. Results: Statistically significant reductions in PD (p < 0.001) and CAL (p < 0.001) were observed in all three treatment groups at 3 and 6 months follow-up compared to baseline, with no significant differences between the groups. No significant differences were found in bleeding on probing at 3 and 6 months and in radiographic bone density at 6 months of follow-up. Conclusion: The results indicated that, compared to isolated basic periodontal therapy (TPB), adjunctive photobiomodulation did not provide additional benefits, regardless of the laser application technique used (AU).

Dental anxiety and oral health-related quality of life before and after non-surgical periodontal treatment.

OBJECTIVES: To (1) investigate dental anxiety (DA) and oral health-related quality of life (OHRQOL) before and after non-surgical periodontal treatment (NSPT) and (2) determine correlations between these patient-reported measures. MATERIALS AND METHODS: Demographics, smoking habits, dental pain, Modified Corah's Dental Anxiety Scale (MDAS), and Oral Health Impact Profile (OHIP-14) were assessed in eighty-two participants. RESULTS: Mean age was 48.3 years ± 11.5. At baseline, 8.5% reported being active smokers. Of non-smokers, 11% reported being an ex-smoker. After NSPT, 11.0% reported smoking. Patients' maximal pain in the last month decreased after therapy. Before treatment, participants reported higher DA. Extreme DA was observed in 8.5% of participants before therapy. Afterwards, 2.4% of participants reported extreme DA. Fear of having a foreign object in the mouth decreased after NSPT. All OHIP-14 scores, except functional limitation, improved post-treatment. Higher DA was associated with worse OHRQoL before treatment. After treatment, total MDAS score was associated with OHIP-14 global score, physical pain, psychological disability, and social disability. Worse MDAS sub-scores were associated with a higher OHIP-14 global score. Individuals with "normal/slight anxiety" had a significant improvement in OHRQoL, whereas people in the "moderate and extreme anxiety" group did not report a significant improvement. Patients diagnosed with generalized periodontitis (GP) stage III grade B and GP stage IV grade B reported less anxiety after NSPT. CONCLUSIONS: Associations of MDAS subcategories with OHIP-14 domain scores were found before and after therapy. DA decreases and OHRQoL enhances after NSPT in patients with "normal/slight" anxiety to dental treatment. Dental practitioners should plan strategies to cope with anxiety to dental treatment and prevent decreases in OHRQoL. CLINICAL RELEVANCE: Within the limitations of this study, DA and OHRQoL were positively correlated in patients with periodontitis, before and after NSPT, using the MDAS and OHIP-14 questionnaires. The results of our study suggest that treatment is effective in terms of alleviating DA and improving oral health, along with quality of life, in patients that report "normal/slight" anxiety to dental treatment. Nonetheless, results must be interpreted with caution since patients are generally anxious before any type of dental treatment. DA may not just be confined to NSPT per se. According to our results, evaluation of both outcomes should be an integral part of routine periodontal clinical evaluation and periodontal reevaluation of initial therapy. It is important that clinicians learn to identify patients that suffer from anxiety and take time to explain the treatment procedures to the patient, to strive for patient's emotional well-being before, during, and after dental care services. The use of specific questionnaires for both DA and OHRQoL may be more appropriate to demonstrate the psychological and quality of life differences due to periodontal disease and NSPT.

Eficiencia de la terapia periodontal no quirúrgica en la actividad clínica de la artritis reumatoide

Introducción: El efecto del tratamiento no quirúrgico periodontal en los pacientes con artritis reumatoide es escaso y controversial. Objetivo: Evaluar el efecto de la terapia periodontal no quirúrgica en la actividad de la artritis reumatoide. Métodos: Se realizó un estudio cuasi experimental de intervención terapéutica en 30 pacientes de ambos sexos entre 35 y 70 años de edad con diagnóstico clínico de artritis reumatoide y periodontitis. Fueron incluidos en este estudio los pacientes con más de ocho dientes presentes y aprobación escrita para participar en la investigación y excluidos las embarazadas, fumadores y los que recibieron terapia periodontal o antibiótica. Los parámetros clínicos-serológicos y periodontales fueron evaluados antes y 30 días después de la terapia periodontal. Las variables estudiadas fueron: formas de periodontitis y actividad de la enfermedad reumática (DAS-28/VSG). Se utilizaron frecuencias absolutas, relativas, chi-cuadrado y correlación de Spearman al 95 % de confianza. Resultados: El grupo de edad de 45-54 años y el sexo femenino fueron predominantes. La periodontitis incipiente y moderada fue la más prevalente antes del tratamiento periodontal y estuvo asociada a los niveles de actividad moderada de la AR. Tras el tratamiento periodontal se confirmó disminuciones en el estado periodontal y en la actividad de la afección reumática en el 73.3 % de los pacientes. Conclusiones: La terapia periodontal no quirúrgica mejoró el estado periodontal y redujo la actividad de la artritis reumatoide.

Introduction: The effect of nonsurgical periodontal treatment in patients with rheumatoid arthritis is limited and controversial. Objective: To evaluate the effect of non-surgical periodontal therapy on the activity of rheumatoid arthritis. Methods: a quasi-experimental study of therapeutic intervention was carried out in 30 patients of both sexes between 35 and 70 years of age with a clinical diagnosis of rheumatoid arthritis and periodontitis. Patients with more than eight teeth present and written approval to participate in the research and excluded were included in this study: pregnant women, smokers and those who received periodontal or antibiotic therapy. The clinical - serological rheumatoid and periodontal parameters were evaluated: before and 30 days after periodontal therapy. The variables studied were: forms of periodontitis and activity of the arthritic disease. Absolute and relative frequencies, chi-square and Spearman's correlation at 95 % confidence were used. Results: The age group of 45-54 years and the female sex were predominant. Early and moderate periodontitis was the most prevalent before periodontal treatment and was associated with moderate levels of rheumatoid activity. After periodontal treatment, decreases in periodontal status and rheumatic disease activity were confirmed in 73.3 % of patients. Conclusions: Non-surgical periodontal therapy improved the periodontal status and activity levels of rheumatoid arthritis.

Impact of serum vitamin D levels on periodontal healing outcomes: A preliminary cohort study.

OBJECTIVE: To evaluated the relationship between serum vitamin D levels and periodontal healing outcomes in patients with mild or moderate periodontitis. METHODS: Serum vitamin D levels and periodontal pockets and gingival bleeding were evaluated in 51 patients before and 6 months after non-surgical periodontal treatment. A t-test and chi-square test were used to analyse the data (p ≤ 0.05). RESULTS: The mean reduction of periodontal pocket depth was statistically significant higher in patients with vitamin D ≥30 ng/ml than those with <30 ng/ml (CI = -0.23-0.42, p = 0.05), but not clinically significant. Vitamin D level was not associated with the percentage of sites of gingival bleeding on probing at the final evaluation (OR = 0.58, 95% CI = 0.17-1.99, p = 0.39). CONCLUSION: Lower serum vitamin D level was associated with a slightly reduced periodontal healing after non-surgical periodontal therapy, which should be further investigated in a larger population.

Nonsurgical periodontal treatment in type II diabetics in a middle-income country: a cost-effectiveness analysis.

OBJECTIVES: To evaluate the cost-effectiveness of the nonsurgical periodontal treatment (NSPT) compared with supragingival therapy in type II diabetics with periodontitis. METHODS: A decision tree analysis was used to estimate the costs and health outcomes of two periodontal therapies in a hypothetical cohort of type II diabetics with periodontitis. The analysis was developed from the perspective of a third-party payer at 1 year and 5 years. Probabilities were derived from two systematic reviews. The costs and resource use were validated by a Delphi expert panel. All costs were expressed in USD, using the 25 May 2021 Colombian pesos market exchange rate (USD 1 = COP 3,350). RESULTS: NSPT was a dominant alternative compared with subsidized supragingival therapy in type II diabetics with periodontitis, generating savings of USD 87 and 400, during the first year or up to 5 years, respectively, and improving dental survival from 32 to 69 percent. CONCLUSIONS: NSPT can generate savings by reducing the complications derived from uncontrolled periodontitis and tooth loss.

Effect of desensitizing agents on dentin hypersensitivity after non-surgical periodontal therapy: A systematic review and meta-analysis.

OBJECTIVE: To investigate the effectiveness of desensitizing agents (DA) on dentin hypersensitivity (DH) after non-surgical periodontal treatment (NSPT) through a systematic review and meta-analysis. DATA: The PICO strategy was used to include randomized clinical trials in human subjects with DH (P) after NSPT treated with DA (I) compared to those treated with placebo or control (C) to identify DH relief (O). The Cochrane guidelines and GRADE was used to classify the risk of bias and the quality of the evidence, respectively. SOURCES: PubMed, Web of Science, Scopus, Lilacs, Cochrane Library databases, and OpenGrey were searched on the 20th of May 2020. STUDY SELECTION: Nine studies were included in the quantitative synthesis. Five meta-analyses were performed. Three meta-analyzes assessed the effectiveness of DA compared to a placebo or control in relation to pain assessment stimuli and two meta-analyzes assessed the mechanism of action of DA. For the mechanical stimulus in overall analysis, the control group presented a higher mean of pain reduction (SMD 1.03 [0.73, 1.32], p < 0.001) with very low certainty of evidence. For water (SMD -0.78 [-1.22, -0.35], p = 0.0009) and evaporative in overall analysis (SMD -1.21 [-1.79, -0.64], p < 0.001) stimuli, the DA decreased DH pain with very low and low certainty of evidence, respectively. CONCLUSION: Due to the limited quality of evidence, there is no definitive conclusion on the effectiveness of DA on DH after NSPT. Thus, further clinical studies with a low risk of bias and high-quality evidence are encouraged to reinforce the certainty of evidence on that issue. CLINICAL SIGNIFICANCE: The use of desensitizing agents show promise for relief of dentin hypersensitivity after non-surgical periodontal therapy.

Impact of non-surgical periodontal treatment on salivary expression of cytokines related to bone metabolism.

We aimed to evaluate the impact of non-surgical periodontal treatment on the salivary expression of leptin, TNF-α, sclerostin, parathyroid hormone, osteoprotegerin, osteopontin, osteocalcin, IL-6, IL-1ß and fibroblast growth factor 23 in patients with chronic periodontitis after 1 year of follow-up. Fifteen patients with chronic periodontitis (56.0 ± SD 9.6 years) and 15 subjects with gingivitis (39.7 ± SD 4.4 years) were included in the study. Clinical periodontal parameters, such as probing pocket depth (PPD), clinical attachment level (CAL), % of plaque and bleeding on probing (BOP) were evaluated, and non-stimulated whole saliva was collected from all patients before periodontal treatment and after 1 year of follow-up. A bead-based multiplex assay measured cytokines. In the chronic periodontitis group, periodontal treatment significantly improved clinical parameters and reduced the salivary levels of IL-1ß, leptin and TNF-α (p = 0.002, 0.007 and 0.015, respectively). In the gingivitis group, there were also significant improvements in the mean patient %BOP, % Plaque, CAL and PPD. However, there were no significant changes in the cytokine's salivary levels. In conclusion, chronic periodontitis patients showed a significant reduction in the salivary levels of leptin, TNF-α and IL-1ß 1 year after periodontal treatment and a significant improvement in their clinical periodontal parameters suggesting that periodontal treatment alone can downregulate important cytokines associated with bone metabolism.

Eficacia de terapia fotodinámica como complemento de terapia convencional periodontal versus terapia convencional en el tratamiento de pacientes adultos con periodontitis crónica: una revisión sistemática con metaanálisis / Effectiveness photodynamic therapy complementing conventional periodontal therapy versus conventional therapy in the treatment of adult patients with chronic periodontitis: a systematic review with meta-analyses

Se evaluó la eficacia de la terapia fotodinámica como complemento de terapia periodontal convencional comparándola con la terapia convencional en el tratamiento de sacos periodontales en pacientes adultos con periodontitis crónica basándose en ensayos clínicos comprendidos entre los años 2010 y 2015, para determinar si su uso otorga mejores resultados para el tratamiento de esta enfermedad. Se seleccionaron ensayos clínicos aleatorios prospectivos, aleatorizados o no aleatorizados, controlados y no controlados que permitieron la comparación entre el tratamiento convencional y la terapia fotodinámica, con un grupo en el cual se utilizó sólo la terapia convencional. Los datos de los ensayos clínicos fueron ingresados al software Review Manager®. Se realizaron tres metaanálisis para las variables: Nivel de inserción clínica (NIC) y profundidad de sondaje (PS), el test de I2 fue utilizado para medir la heterogeneidad del estudio y posteriormente un análisis de sensibilidad para determinar los estudios heterogéneos. Se pudieron analizar 7 estudios, con un total de 186 pacientes, quienes fueron controlados 3 meses post tratamiento. Se utilizó la diferencia de medias, un intervalo de confianza de 95 % para medir el NIC y PS. A los 3 meses, no se encontró diferencias significativas en NIC (p= 0,93) y PS (p= 0,71). Conclusión: La terapia fotodinámica en complementación a la terapia convencional no otorga mejor resultado clínico ni estadístico comparado con la terapia convencional al evaluar el nivel de inserción clínica. Al evaluar la profundidad de sondaje es recomendable la utilización de terapia convencional sola.

The efficacy of photodynamic therapy as an adjunct to conventional periodontal therapy evaluated by comparing with conventional therapy alone in the treatment of periodontal pockets in adult patients with chronic periodontitis based on clinical trials between 2010 and 2015, to determine if its use can provide better results for treating this disease. Prospective randomized clinical trials and randomized clinical trials or non-randomized, controlled and uncontrolled that allowed comparison between a group which was applied to conventional therapy and photodynamic therapy, a similar group was selected to which you He applied only conventional therapy. Data from clinical trials entered into Review Manager®. Three meta-analyzes for the variables analyzed were performed: Level clinical attachment (NIC) and probing depth (PS), the test of I2 was used to measure the heterogeneity of the study and then a sensitivity analysis to determine which studies awardedheterogeneity. As results, seven studies analyzed in 186 patients who underwent treatment at least controlled within 3 months post treatment. The mean difference was used, a confidence interval of 95 % to measure the NIC and PS. At 3 months, no significant differences in NIC (p= 0.93) and PS (p= 0.71). In conclusion, the photodynamic therapy complementary to conventional therapy does not provide better clinical or statistical results compared with conventional therapy to evaluate the clinical attachment level. In assessing probing depth, is advisable to use conventional therapy alone.

Tratamiento periodontal no quirúrgico en pacientes con gingivitis y periodontitis moderada. Respuesta bioquímica y microbiológica / Non surgical periodontal treatment in patients with gingivitis and moderate periodontitis. Biochemical and microbiological response

Objetivo: Conocer la respuesta inflamatoria a través de la presencia de interleucina 1β e identificar microorganismos patógenos como posibles marcadores inmunológicos y microbiológicos en el diagnóstico y tratamiento periodontal no quirúrgico en sujetos con gingivitis y periodontitis crónica moderada en población mexicana. Material y métodos: En este estudio prospectivo de cohortes, se seleccionaron 18 pacientes con signos clínicos de gingivitis y 17 pacientes con periodontitis crónica moderada, se recolectaron las muestras de biopelícula subgingival y de fluido gingival crevicular. Se cuantificó la interleucina 1β durante las fases pretratamiento, postratamiento y de mantenimiento del tratamiento periodontal no quirúrgico. Resultados: Las variables de respuesta microbiológica mostraron que Porphyromonas gingivalis, Prevotella intermedia, Fusobacterium nucleatum, Aggregatibacter actinomycetemcomitans disminuyeron significativamente en individuos con gingivitis. Así como Porphyromonas gingivalis, Tannerella forsythia, Fusobacterium nucleatum, Aggregatibacter actinomycetemcomitans y Actinomyces sp. en periodontitis crónica moderada. Las variables de respuesta bioquímica mostraron una disminución significativa en la concentración y cuenta total de interleucina 1β en los individuos con periodontitis crónica moderada en la fase de mantenimiento del tratamiento así como de las variables de respuesta clínica. Conclusión: Hay reducción de los niveles de interleucina 1β con la disminución de la microflora. Los niveles de interleucina 1β son marcadores sensibles para el diagnóstico y severidad de la enfermedad periodontal.

Objective: To ascertain inflammatory response through interleucina 1β presence and identify pathogenic microorganisms as possible immunological and microbiological markers in diagnosis and treatment non-surgical periodontal in patients with gingivitis and moderate chronic periodontitis in a sample of Mexican population. Material and methods: In the present prospective cohort study, 18 patients with signs of gingivitis and 17 patients with moderate chronic periodontitis were selected. Samples of subgingival biofilm and of crevicular gingival fluid were collected. Interleukine 1β was quantified during the pre-treatment, post-treatment and maintenance phases of the nonsurgical periodontal treatment. Continuous variables were analyzed with the Student test, as well as categorical variables which were analyzed with the TurkeyKramer test. For independent groups the Pearson test was used. Results: Microbiological response variables showed that Porphyromonas gingivalis, Prevotella intermedia , Fusobacterium nucleatum , Aggregatibacter actinomycetemcomitans significantly decreased in subjects with gingivitis. Porphyromonas gingivalis , Tannerella forsythia , Fusobacterium nucleatum , Aggregatibacter actinomycetemcomitans and Actinomyces ssp . decreased in cases. Biochemical response variables showed significant decrease in IL-1β concentration and total count in individuals with moderate chronic periodontitis in treatment maintenance phase. The same result applied to clinical response variables. Conclusions: There is a decrease in Interleukin 1β levels with decrease in microflora. Interleukin 1β are sensitive markers for diagnosis of periodontal disease and assessment of its severity.

Additional effects of homeopathy on chronic periodontitis: a 1-year follow-up randomized clinical trial.

BACKGROUND AND OBJECTIVE: The aim of this study was test the hypothesis that homeopathy (H) enhances the effects of scaling and root planing (SRP) in patients with chronic periodontitis (CP). MATERIALS AND METHODS: 50 patients with CP were randomly allocated to one of two treatment groups: SRP (C-G) or SRP + H (H-G). Assessments were made at baseline and after 3 and 12 months of treatments. The local and systemic responses to the treatments were evaluated by clinical and serologic parameters, respectively. RESULTS: Both groups displayed significant improvements, however, using clinical attachment gain and reductions in HDL, LDL and Total Cholesterol, Triglycerides, Glucose and Uric acid, from baseline to 1 year, as criteria for treatment success, H-G performed significantly better than C-G. CONCLUSION: The findings of this 1-year follow-up randomized clinical trial suggest that homeopathic medicines, as an adjunctive to SRP, can provide significant local and systemic improvements for CP patients.

The impact of non-surgical periodontal treatment on serum levels of long chain-polyunsaturated fatty acids: a pilot randomized clinical trial.

BACKGROUND AND OBJECTIVE: Our group recently found higher levels of serum long chain-polyunsaturated fatty acids (LC-PUFAs) in patients with chronic periodontitis compared to controls. However, the effect of periodontal treatment on LC-PUFA serum levels has not been investigated. The primary aim of the present study was to investigate the impact of periodontal treatment on LC-PUFA serum levels. A secondary aim was to assess the effect of dietary ω-3 supplementation on clinical outcome. MATERIAL AND METHODS: The test group was composed of 10 patients with generalized chronic periodontitis (mean age 44 ± 6.4 years) treated with scaling and root planing associated with 4 mo of ω-3 supplementation eicosapetaenoic acid (EPA) plus docosahexaenoic acid (DHA), 3 g/d. The placebo group was composed of 11 patients (47.9 ± 10.5 years) that received scaling and root planing plus placebo. The periodontal examination included probing depth, clinical attachment level, bleeding on probing and visible plaque index. Docosapentaenoic acid (DPA), EPA, DHA and arachidonic acid (AA) were detected using gas chromatograph. RESULTS: In the placebo group, all LC-PUFAs levels reduced significantly (DHA, DPA and AA, p = 0.004; EPA, p = 0.008). In the test group, only DPA and AA showed a significant reduction (p = 0.005). Moreover, a significant decrease in the ratios AA/EPA and AA/DHA (p = 0.005) was observed in the test group. CONCLUSION: Non-surgical periodontal treatment reduced significantly the serum levels of all analyzed LC-PUFAs except those presented in the supplementation. The ω-3 dietary supplementation had no effect on clinical outcome of treatment.

Tratamento periodontal não cirúrgico em mulheres obesas e não obesas com periodontite crônica: um estudo longitudinal / Non-surgical periodontal treatment in obese and non-obese women with chronic periodontitis: a longitudinal study

A proposta deste estudo intervencional e prospectivo foi comparar a resposta ao tratamento periodontal não cirúrgico em mulheres obesas e não obesas com periodontite crônica após 3, 6 e 12 meses. Assim como, avaliar um mediador inflamatório no fluido crevicular gengival (FCG), o fator de necrose tumoral alfa (TNF-α), no início do estudo e após 3 meses de tratamento periodontal. O perfil lipídico incluindo lipoproteína de alta densidade (HDL), lipoproteína de baixa densidade (LDL), triglicerídeos (TG) e colesterol total (CT) também foi avaliado no início do estudo, 3, 6 e 12 meses após o tratamento periodontal. Trinta mulheres obesas e trinta e uma não obesas com periodontite crônica realizaram o tratamento periodontal na Faculdade de Odontologia da Universidade Federal do Rio de Janeiro. A avaliação médica com anamnese e os dados socioeconômicos foram coletados no início do estudo. Três medidas antropométricas foram utilizadas para classificação de obesidade: o índice de massa corporal (IMC), a circunferência da cintura (CC) e a razão cintura-quadril (RCQ). Os seguintes parâmetros clínicos periodontais, nível clínico de inserção (NCI), profundidade de sondagem (PS), placa visível (PV) e sangramento à sondagem (SS), foram coletados nos 4 momentos do estudo. Amostras do FCG foram coletadas em 1 sítio saudável (sem SS e com PS ≤ 3 mm) e 1 sítio doente (com SS e PS ≥ 5mm) antes e após 3 meses do tratamento periodontal, sendo analisadas através de técnica imunoenzimática. Comparação intergrupos dos dados socioeconômicos e da média da porcentagem dos parâmetros clínicos foram obtidas pelos testes de Qui-quadrado e Mann-Whitney, respectivamente. A média dos parâmetros clínicos periodontais e o perfil lipídico foram comparados ao longo do tempo em cada grupo, utilizando o teste de Friedman e o FCG através do teste de Wilcoxon; o teste de Mann-Whitney foi utilizado para as comparações entre grupos em cada momento do estudo. Uma melhora dos parâmetros clínicos periodontais, NCI, PS, PV e SS, foi observada nos 4 momentos do estudo para os dois grupos, entretanto sem diferença significativa entre grupos. Uma análise utilizando o modelo de generalized estimating equations (GEE) para avaliar a melhora de NCI e a redução de PS, definidos como, sítios que tinham ≥ 4 mm no início do estudo e ganharam NCI ou reduziram PS ≥ 2 mm, não demonstrou associação da resposta ao tratamento periodontal com a obesidade. Não houve diferença significativa, entre os grupos, nas concentrações de TNF- α após o tratamento periodontal. Entre os grupos observou-se uma diferença, com melhores resultados para mulheres não obesas aos 3 meses no HDL, TG e CT; aos 6 meses no HDL, LDL e TG, e aos 12 meses no HDL e nos TG. Nossos resultados sugerem que mulheres obesas e não obesas apresentaram uma melhora de todos os parâmetros clínicos periodontais, sem diferença entre os grupos, ao serem avaliadas aos 3, 6 e 12 meses após o tratamento periodontal não cirúrgico. Assim como, as concentrações do TNF-α em sítios saudáveis e doentes foram similares, entre grupos e o perfil lipídico apresentou uma melhora no HDL e TG nas mulheres não obesas. AU)

The purpose of the present interventional and prospective study was to compare the response to non-surgical periodontal treatment in obese and non-obese women with chronic periodontitis. As well as, evaluate one inflammatory mediator, tumor necrosis factor-alpha (TNF-α) in gingival crevicular fluid (GCF), at baseline and 3 months after periodontal treatment. The lipid profile including high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglycerides (TG) and total cholesterol (TC) were also evaluated at baseline, 3, 6 and 12 months. Thirty obese and thirty-one non-obese women with chronic periodontitis received periodontal treatment at School of Dentistry of Federal University of Rio de Janeiro. In the beginning of the study, medical and a sociodemographic data were collected. Three anthropometric measures were used to classify the subjects for obesity: body mass index (BMI), waist circumference (WC) and waist to hip-ratio (WHR). The following clinical periodontal parameters, clinical attachment level (CAL), probing on depth (PD), visible plaque (VP) and bleeding on probing (BOP), were recorded at baseline, 3, 6 and 12 months. Samples of gingival crevicular fluid (GCF) were collected at 1 healthy site (without BOP and PD ≤ 3mm) and 1 diseased site (with BOP and PD ≥ 5mm) before and after periodontal treatment, analyzed by immunoenzymatic technique. Intergroup comparison of sociodemographic data and the mean percentage of periodontal clinical parameters were obtained by Chi-square and Mann-Whitney, respectively. The mean of clinical periodontal parameters and the lipid profile were compared for each group during time, using the Friedman test; The GCF was analyzed with Wilcoxon test. Mann-Whitney was used for comparison between groups in each moment of the study. The improvement of periodontal clinical parameters, CAL, PD, VP and BOP was observed in the 4 moments of the study for each group; however, without significant difference between groups. In one analyses using Generalized Estimation Equation (GEE) model to evaluate the improvement of CAL and reduction of PD, defined as, sites ≥ 4 mm at baseline and CAL gain or PD reduction ≥ 2 mm, did not demonstrated association of periodontal treatment response with obesity. There was no significant difference between groups in TNF-α concentration after periodontal treatment. There was a difference, between groups, with better results for non-obese women at 3 months on HDL, TG and TC; at 6 months on HDL, LDL and TG, and at 12 months on HDL and TG. Our results suggested that obese and non-obese women improved in all clinical parameters, with no difference between groups, when evaluated at 3, 6 and 12 months after non-surgical periodontal treatment. The TNF-α in healthy and diseased sites were similar between groups and the lipid profile showed an improvement in HDL and TG in non-obese women at 12 months post-treatment. (AU)

Control Glucémico de Diabetes Mellitus y Tratamiento de Enfermedades Periodontales: Reporte de Dos Casos Clínicos / Diabetes Mellitus Glycemic Control and Treatment of Periodontal Diseases: Report of Two Cases

Las Enfermedades Periodontales afectan de forma adversa el control metabólico de Diabetes Mellitus. Se postula que si un paciente diabético mantiene salud periodontal a través del tratamiento periodontal no quirúrgico puede mejorar el control glucémico. Por lo tanto el identificar pacientes con enfermedad periodontal avanzada puede ser un elemento clínico relevante para sospechar de diabetes no diagnosticada y su tratamiento puede tener un efecto positivo en el control metabólico de la diabetes, medido a través de los niveles de hemoglobina glucosilada (HbA1c). En el primer caso se da seguimiento a un paciente con Diabetes Mellitus tipo 1 y en el segundo reporte clínico a un paciente con Diabetes Mellitus tipo 2, con el objetivo de observar si el tratamiento periodontal mejora el control glucémico. Después del tratamiento periodontal no quirúrgico, en ambos casos clínicos existió disminución de hemoglobina glucosilada (HbA1c) teniendo un efecto positivo el tratamiento periodontal en el control metabólico medido a través de los niveles de hemoglobina glucosilada (HbA1c).

Periodontal Diseases affect Diabetes Mellitus metabolic control adversely. It is stated that if a diabetic patient keeps his/her periodontal health by means of a non-surgical periodontal treatment, his/her glycemic control can improve. Therefore, to identify patients with advanced periodontal diseases it can be a relevant clinical element to suspect a non-diagnosed diabetes and its treatment can have a positive effect on the diabetes metabolic control, measured through glycosylated hemoglobin levels (HbA1c). In the first case, a patient with Diabetes Mellitus type 1 is followed up, and in the second clinical report a patient with Diabetes Mellitus type 2 was followed up with the purpose of observing whether the periodontal treatment improves glycemic control. After the non-surgical periodontal treatment, there was a glycosylated hemoglobin decrease (HbA1c), with periodontal treatment having a positive effect on the metabolic control measured through glycosylated hemoglobin levels (HbA1c).

Avaliação do sucesso da terapia periodontal não cirúrgica. Follow up de período curto / Evaluation of the success of nonsurgical periodontal therapy. Short time follow-up

Objetivo: Avaliar o sucesso do tratamento periodontal não cirúrgico após 6 meses da conclusão da terapia periodontal. Materiais e Métodos: um total de 11 indivíduos foi selecionado com base em critérios previamente estabelecidos de modo a assegurara consistência dos resultados. Os exames supragengivais e subgengivais consideraram o índice de placa visível (IPV); o índice de sangramento gengival (ISG); a profundidade de sondagem(PS), o nível clínico de inserção (NIC) e sangramento a sondagem (SS) obtidos no início e no final do tratamento. Os dados foram agrupados em faces livres (vestibular e lingual) e faces proximais (mesial e distal), sendo comparados os resultadosdos exames iniciais com os exames finais, realizados no estudo. Os testes estatísticos utilizados foram: o teste T de Studente o teste Qui-Quadrado, ambos para uma significância de5%. Resultados: verificou-se que os pacientes apresentaram redução de todos os parâmetros clínicos analisados, confirmado pela média dos indicadores IPV, ISG, SS, PS e NIC dos pacientes tratados. Conclusão: foi observado melhora nos indicadores de saúde periodontal, após três meses da terapia periodontal não cirúrgica, isentando os pacientes do desconforto pós-cirúrgico e sem afetar o sistema imunológico dos mesmos, através de antibióticoterapia.

Aim: The aim of this study was to evaluate the success of nonsurgical periodontal treatment after 6 months of completion of periodontal therapy. Material and Methods: A total of 11 individuals was selected based on criteria established in advance in order to ensure consistency of results. Tests supragingival and subgingival considered the visible plaque index (VPI), the gingival bleeding index (GBI), probing depth (PD) and clinical attachment level (NIC), obtained at the beginning and end of treatment. The data were grouped into free faces (facial and lingual) and proximal surfaces (mesial and distal) and compared the resultsof initial tests with the final exams in the study. Statistical tests used were Student's t test and chi-square test, both for a 5% significance. Results: we found that patients showed a reduction in all clinical parameters were analyzed and confirmed by theaverage indicators of IPV, SS, PS and NIC of patients treated by exempting them from the post-surgical discomfort and without affecting the immune system of individuals. Conclusion: There was improvement in indicators of periodontal health, after thee valuation of six months of nonsurgical periodontal therapy, freeing patients from the discomfort after surgery and without affecting the immune system of the same.

Efeitos do tratamento periodontal não cirúrgico sobre a densidade e altura óssea alveolar / Effects of non surgical periodontal treatment on the alveolar bone dentity

O objetivo deste trabalho foi avaliar o efeito do tratamento periodontal não cirúrgico (TPNC), na densidade e na altura óssea alveolar, em pacientes com periodontite, utilizando radiografias digitais diretas. Cento e um sítios, em dezenove pacientes (idade média 36 ± 7.3 anos) foram acompanhados no dia 0, e 90 e 180 dias após TPNC. Os índices clínicos de profundidade de bolsa a sondagem (PBS), nível de inserção clínica, sangramento à sondagem e índice de placa foram registrados e radiografias digitais foram feitas. A densidade foi analisada através de regiões ósseas de interesse colocadas sobre a crista óssea alveolar (ROI I) e sobre o osso medular (ROI II). A altura óssea alveolar foi medida através da distância da crista óssea alveolar até a junção cemento esmalte. Os sítios profundos (PBS ≥ 5mm) apresentaram uma melhora clínica significante (p <0.01), acompanhada de um aumento na densidade da ROI I (p <0.01). A ROI II mostrou um aumento na densidade dos sítios com PBS ≤ 3mm em pacientes com periodontite agressiva (p <0.05). No entanto, houve diminuição nos sítios com PBS ≥ 5mm nesses mesmos pacientes (p <0.03). A altura óssea alveolar não sofreu alteração após TPNC. Após o tratamento periodontal não cirúrgico, observou-se que as radiografias obtidas através da técnica digital direta parecem mostrar um aumento na densidade da crista óssea, nos sítios profundos dos pacientes com periodontite. No entanto, a redução da profundidade de bolsa e do ganho no nível de inserção clínica não foi acompanhada por alterações significantes na altura óssea alveolar nestes sítios.

The aim of this study was to access the effects of non-surgical periodontal treatment (NSPT), on the bone density and alveolar bone height (ABH), in patients with periodontitis, using direct digital radiographs. One hundred one sites in nineteen patients (mean age 36 ± 7.3 years) were accompanied on day 0, and 90 and 180 days after the TPNC. The clinical scores of probing pocket depth (PPD), clinical attachment level, bleeding on probing and plaque index were registered and digital radiographs were taken. The density was accessed considering the bone regions of interest at the alveolar bone crest (ROI I) and the medullar bone (ROI II). The ABH measured the distance between the alveolar bone crest and the cementoenamel junction. The deep sites (PPD ≥ 5mm) presented a clinical improvement (p <0.01), accompanied by an increase in bone density at ROI I (p <0.01). ROI II showed an increase in density at sites with PPD ≤ 3mm in patients with aggressive periodontitis (p <0.05). However, there was a decrease in density in sites with PPD ≥ 5mm of the same patients (p <0.03). The ABH didn´t change after TPNC. After non-surgical periodontal treatment, the direct digital radiographs showed a significant increase in bone crest density of deep sites in patients with periodontitis. Moreover, the reduction in the probing pocket depth and the increase in the attachment level were not followed by changes in alveolar bone height in these sites.

Relationship between periodontitis and rheumatoid arthritis and the effect of non-surgical periodontal treatment

This study analyzed the association of periodontal disease (PD) and rheumatoid arthritis (RA). Seventy-five 35-60-year-old patients were assigned to 5 groups according to the presence (+) or not (-) of PD and RA and the treatment received (TR+) or not (TR-) for PD. Group 3 uses total prosthesis (TP). Clinical and laboratory evaluations were performed at baseline, 3 and 6 months of follow-up by probing pocket depth, bleeding on probing and plaque index for PD, HAQ, DAS28, SF-36 and laboratory: AAG, ESR, CRP for RA. Statistically significant differences for PD after 3 (p=0.0055) and after 6 months (p=0.0066) were obtained in Group 1 (RA+PD+TR+) and 2(RA+PD+TR-); significant reduction in the percent of BOP after 6 months (p=0.0128) and significant reduction in the percent of Pl after 3 (p=0.0128) and 6 months (p=0.0002) in Group 1. Statistically significant differences between Groups 1 and 3 (RA+TP) for DAS28 at baseline and after 3 months were observed, but not after 6 months. No other parameters for RA were significantly affected. The relationship between RA and PD disease activities is not clear, but the importance of periodontal treatment in the control of inflammation to avoid tooth extraction is evident.

Este estudo avaliou a influência da doença periodontal (DP) na artrite reumatóide (AR). 75 pacientes, 35-60 anos, divididos em 5 Grupos, considerando a situação sistêmica e periodontal foram analisados. Um Grupo usava prótese total (PT). Os parâmetros clínicos e laboratoriais analisados: inicial, 3 e 6 meses receberam tratamento estatístico. As correlações entre as reduções da profundidade de sondagem, placa microbiana e sangramento à sondagem com as de Alfa 1, PCR, VHS e exames de qualidade de vida (HAQ, DAS28, SF36) foram também analisadas. Comparando o Grupo 1 (AR+DP+TR+) e Grupo 2 (AR+DP+TR-), aqueles que receberam tratamento periodontal não-cirúrgico (TPNC) tiveram reduções estatisticamente significativas em relação a PS aos 3 meses (p=0,0055) e 6 meses (p=0,0066); as reduções da por cento SS foram estatisticamente significantes aos 6 meses (p=0,0128) e da por cento PM aos 3 (p=0,0128) e 6 meses (p=0,0002). O TPNC não apresentou correlação com a melhora dos exames laboratoriais, nem com os exames de qualidade de vida. Comparando o Grupo 1 com o Grupo 3 (AR+PT) houve diferença estatisticamente significante no DAS28 inicial e 3 meses. Não foi possível verificar uma correlação direta do TPNC na atividade da doença sistêmica, mas pode-se constatar a sua importância, evitando a extração múltipla dos dentes.
