Tratamento de periodontite estágio III localizado grau C em um indivíduo fumante: um relato de caso / Treatment of periodontitis stage III localized grade C in smoker individual: a case report

Objetivo: A periodontite é uma doença infecto-inflamatória que acomete os tecidos de inserção periodontal, e ser fumante representa um risco modificável significativo para todos os graus da doença. Ainda, indivíduos fumantes apresentam uma resposta inflamatória alterada quando comparados a não fumantes. Nesse contexto, o objetivo deste estudo foi reportar um relato de caso de tratamento periodontal de paciente fumante pesado. Relato de caso: O paciente DRS, sexo masculino, 22 anos, foi encaminhado à Faculdade de Odontologia da Universidade Federal de Pelotas (UFPel) com a queixa principal de necessidade de "realização de uma limpeza dentária". Na anamnese, relatou fumar 20 cigarros ao dia, há 7 anos (7 maços-ano). Na consulta inicial, foi encontrado índice de placa visível (IPV) de 100% e índice de sangramento gengival (ISG) de 66,67%. Foi encontrado cálculo supragengival como fator retentivo de placa (FRP) em 46,30% dos sítios. Estabeleceu-se o diagnóstico de periodontite estágio III localizado grau C. Os exames periodontais foram realizados por um único pesquisador calibrado e optou-se pelo tratamento periodontal não cirúrgico. Ao exame de 12 meses, o paciente apresentou IPV de 23,45% e ISG de 22,83%. Houve ausência de FRP. De uma forma geral, foi possível constatar a diminuição significativa das bolsas periodontais, bem como o ganho significativo de inserção clínica periodontal. Considerações finais: Dessa forma, é possível concluir a efetividade da terapia periodontal não cirúrgica, aliada à manutenção periodontal e instruções de higiene para o tratamento de periodontite estágio III, grau C, em paciente fumante.(AU)

Objective: Periodontitis is an infect-inflammatory diseases that affects the periodontal attachment tissues, and being smoker represents a significant modifiable risk for all degrees of the disease. Moreover, smokers have an altered inflammatory response when compared to non-smokers. Therefore, the aim of this study was to report a case report of periodontal treatment of a heavy smoker. Case report: A patient DRS, male, 22 years old, was referred to the School of Dentistry of the Federal University of Pelotas (UFPel) with the main complaint of the need to "perform a dental cleaning". During the anamnesis, he reported smoking 20 cigarettes a day for 7 years (7 pack-years). In the initial appointment, a visible plaque index (VPI) of 100% and a gingival bleeding index (GBI) of 66.67% were found. Supragingival calculus was found as a plaque retentive factor (PRF) in 46.30% of the sites. The diagnosis of periodontitis stage III localized grade C was established. Periodontal examinations were performed by a single calibrated researcher and non-surgical periodontal treatment was chosen. At the 12-month appointment, the patient had an VPI of 23.45% and an GBI of 22.83%. There was absence of PRF. In general, it was possible to observe a significant decrease in periodontal pockets, as well as a significant gain in periodontal clinical attachment. Final considerations: Thus, it is possible to conclude the effectiveness of non-surgical periodontal therapy, combined with periodontal maintenance and hygiene instructions for the treatment of periodontitis stage III localized grade C in a smoker.(AU)

Plasma rich in growth factors (PRGF) in non-surgical periodontal therapy: a randomized clinical trial

Abstract The aim of this split mouth, double blinded, randomized clinical trial was to evaluate the clinical efficacy of use of Plasma rich in growth factors (PRGF) as an adjunct to scaling and root planing (SRP) in the treatment of periodontal pockets. Twenty six patients (15 males, 11 females) diagnosed with generalized periodontitis with Pocket Depth > 5mm and plaque index score < 1.5, were randomly allocated by using computer generated random sequence, into two groups, one treated with intra-pocket application of PRGF adjunct to SRP and other with SRP alone. The clinical outcomes like pocket depth (PD), relative attachment level (RAL) and sulcus bleeding index (SBI) were assessed at baseline, 3 months and 6 months. Twenty two patients (44 sites) were analyzed at the end of 6 month follow-up, using SPSS 20.0v software. There was a significant statistical difference observed between both the groups favouring SRP +PRGF group in terms of PD (p = 0.007) and RAL (p = 0.021) at the end of 6 month follow-up. Also there was a statistical significant difference (< 0.001) at all time points compared to baseline, for all parameters in intra-group comparison. Moreover, the sites with PD>4mm necessitating further treatment after 6-month follow-up were significantly lesser for SRP+PRGF group. The use of PRGF technology in non-surgical periodontal therapy, by single intra-pocket application in to periodontal pockets as an adjunct to SRP, in chronic periodontitis patients, was found to be effective in reduction of pocket depth and gain in clinical attachment level.

Comparison of full-mouth scaling and quadrant-wise scaling in the treatment of adult chronic periodontitis

Abstract In the search for the ideal treatment of periodontal disease various non-surgical techniques should be considered. The objective of this study was to evaluate the efficacy of full-mouth scaling (FMS) by clinical and microbiological parameters. 670 individuals were evaluated with 230 subjects meeting the selection criteria and were divided into two groups; 115 subjects treated with FMS and 115 treated with weekly sessions of scaling and root planning (SRP). The patient population had a mean age of 51.67 years, with moderate chronic periodontitis. Subjects were evaluated prior to treatment (T1) and 90 days after execution of therapy (T2), with regards to: probing depth (PD), clinical attachment level (CAL), plaque index (PI), gingival index (GI), and microbial detection for the presence of Porphyromonas gingivalis (P.g.) and Prevotella intermedia (P.i.) by culture method and confirmed by biochemical tests. Subjects treated in the FMS group also rinsed with 0.12% chlorhexidine mouthwash for seven days following treatment. The results were analyzed using statistical Student's t-test and chi-square test. No statistically significant differences were observed for PD and CAL between T1 and T2 in both groups. For GI and PI significant difference was observed between the groups. For the evaluated microbial parameters was observed reduction of P.g. and P.i., but only for P.g. with a significant reduction in both groups. The full mouth scaling technique with the methodology used in this study provided improved clinical conditions and reduction of P.g. in subjects with moderate periodontitis, optimizing the time spent in the therapeutic execution.

Resumo Na busca do tratamento ideal da doença periodontal varias são técnicas não-cirúrgicas que podem ser consideradas. O objetivo deste estudo foi avaliar a eficácia da técnica de desinfecção total de boca (FMD, na sigla em Inglês) por parâmetros clínicos e microbiológicos. Foram avaliados 670 indivíduos com 230 indivíduos atendendo aos critérios de seleção e divididos em dois grupos; 115 indivíduos tratados com FMD e 115 tratados com sessões semanais de raspagem e alisamento corono radicular (SRP, na sigla em Inglês). A população avaliada tinha idade média de 51,67 anos, com periodontite crônica moderada. Os sujeitos foram avaliados antes do tratamento (T1) e 90 dias após a execução da terapia (T2), quanto à profundidade de sondagem (PS), nível de inserção clínica (NIC), índice de placa (IP), índice gengival (IG) e detecção microbiana da presença de Porphyromonas gingivalis (P.g.) e Prevotella intermedia (P.i.) por método de cultura e confirmada por testes bioquímicos. Os indivíduos tratados no grupo FMD também realizaram bochechos com clorexidina 0,12% durante sete dias após o tratamento. Os resultados foram analisados ​​utilizando o teste estatístico t de Student e o teste de qui-quadrado. Não foram observadas diferenças estatisticamente significativas para PS e NIC entre T1 e T2 em ambos os grupos. Para IG e IP observou-se diferença significativa entre os grupos. Para os parâmetros microbianos avaliados foi observada redução de P.g. e P.i., mas apenas para P.g. com uma redução significativa em ambos os grupos. A técnica FMD com a metodologia utilizada neste estudo proporcionou condições clínicas melhoradas e redução da P.g. Em indivíduos com periodontite moderada, otimizando o tempo gasto na execução terapêutica.

Evaluación de la terapia mecánica periodontal en bolsas profundas: respuesta clínica y bacteriológica / Evaluation of periodontal mechanical therapy in deep pockets: Clinical and bacteriological response

Objetivos: Evaluar la composición microbiológica y los parámetros clínicos de bolsas periodontales >5 mm de profundidad al inicio, 1 semana, 3 y 12 meses post raspado y alisado radicular. Materiales y Métodos: Se tomaron registros clínicos y muestras de placa subgingival de 44 sitios de pacientes con diagnóstico de periodontitis crónica. Se identificaron por técnica de Reacción en Cadena de la Polimerasa (PCR) patógenos putativos periodontales: Aggregatibacter actinomycetemcomitans (Aa), Porphyromonas gingivalis (Pg), Treponema denticola (Td), Tannerella forsythia (Tf) y Prevotella intermedia (Pi). Los pacientes recibieron terapia mecánica periodontal y fueron reevaluados a los 7 días, 3 y 12 meses. Resultados: Luego del tratamiento, todos los parámetros clínicos (Placa Bacteriana, Hemorragia, Supuración, Profundidad al Sondaje y Nivel de Inserción Clínica) se redujeron significativamente y los valores obtenidos se mantuvieron hasta los 12 meses. Al inicio, las especies bacterianas prevalentes fueron Pg, presente en 66 por ciento de los sitios, Tf (55 por ciento) y Td (41 por ciento). Los sitios más profundos se relacionaron con las asociaciones Tf-Td (6.8 mm) y Tf-Td-Pi (7 mm). Post terapia, el número de sitios positivos para Td, Tf y Pg se redujo significativamente. Conclusiones: El raspado y alisado radicular mejoró significativamente los parámetros clínicos y redujo la prevalencia de los patógenos periodontales Pg, Tf y Td en bolsas periodontales profundas. Los resultados obtenidos se mantuvieron hasta los 12 meses. No se detectaron mayores pérdidas de inserción clínica en el 86 por ciento de los sitios a 3 meses y en 79 por ciento a los 12 meses. Los sitios en los que el tratamiento no fue efectivo en la eliminación de patógenos a los 12 meses desarrollaron mayores profundidades de sondaje.

Objectives: To evaluate the microbial composition and clinical parameters of periodontal pockets with probing depth >5 mm at baseline, 1 week, 3 and 12 months after scaling and root planning. Methods: Clinical parameters were measured and bacterial samples were collected from 44 sites in 11 patients with chronic periodontitis. By means of Polymerase Chain Reaction (PCR) the presence of Aggregatibacter actinomycetemcomitans (Aa), Porphyromonas gingivalis (Pg), Treponema denticola (Td), Tannerella forsythia (Tf) and Prevotella intermedia (Pi) was estimated. The patients received mechanical periodontal therapy and were evaluated after 1 week, 3 months and 12 months. Results: After treatment, all clinical parameters (Plaque, Bleeding on Probing, Supuration, Probing Pocket Depth and Clinical Attachment Level) were significantly reduced, and the values obtained were maintained up to the 12 months that the study lasts. At baseline, the most prevalent species were Pg, present in 66 percent of the sites, Tf (55 percent) and Td (41 percent). The deepest sites were related to the association Tf-Td (6.8 mm) and Tf-Td-Pi (7 mm). The number of positive sites for Td, Tf and Pg was significantly reduced after therapy. Conclusions: Scaling and root planning improve significantly clinical parameters as well as reduce the prevalence of periodontal pathogens Pg, Td and Tf in deep periodontal pockets. The results obtained were maintained up to 12 months. No further clinical attachment loss was found in 86 percent of the sites at 3 months and 79 percent at 12 months. The sites where the treatment failed in removing pathogens developed at 12 months greater probing pocket depths.

Honeybee propolis extract in periodontal treatment: A clinical and microbiological study of propolis in periodontal treatment.

Objective: This study was conducted to evaluate by clinical and microbiological parameters the effect of subgingival irrigation with propolis extract. Materials and Methods: Twenty patients diagnosed with chronic periodontitis, each presenting three non-adjacent teeth with deep pockets, were selected. Subgingival plaque sampling and clinical recording (at baseline) and scaling and root planing was performed. Two weeks later the selected periodontal sites were submitted to one of the following treatments: Irrigation with a hydroalcoholic solution of propolis extract twice a week for 2 weeks (group A); irrigation with a placebo twice a week for 2 weeks (group B); or no additional treatment (group C). Clinical and microbiological data was collected at baseline and after 4, 6, and 8 weeks. Results: A decrease in the total viable counts of anaerobic bacteria (P=.007), an increase in the proportion of sites with low levels (≤10 5 cfu/mL) of Porphyromonas gingivalis (P=.044), and an increase in the number of sites negative for bleeding on probing was observed in group A sites as compared to group B and C sites. Conclusion: Subgingival irrigation with propolis extract as an adjuvant to periodontal treatment was more effective than scaling and root planing as assessed by clinical and microbiological parameters.

Effectiveness of non-surgical treatment to reduce il-18 levels in the gingival crevicular fluid of patients with periodontal disease

The aim of this study was to evaluate the effectiveness of the non-surgical periodontal treatment in reducing the gingival crevicular fluid (GCF) levels of IL-18 from inflamed periodontal sites. Fourteen patients with periodontal disease were included, being 9 patients with chronic periodontitis (mean age: 48.8 SD ± 7.4 years) and 5 patients with gingivitis (mean age: 43.6 SD ± 11.8). The patients were divided in the following groups: gingivitis sites from periodontitis patients (sites GP), periodontitis sites from periodontitis patients (sites PP), and gingivitis sites from gingivitis patients (sites GG). Probing pocket depth (PPD), probing attachment level (AL), plaque index (PI) and gingival index (GI) were recorded, and gingival fluid samples were collected. The subjects received non-surgical treatment and were re-evaluated 30 days after treatment (day 30 AT). There was a significant reduction in PI in GG (1.0 ± 0.4 to 0.5 ± 0.2), GP (1.2 ± 0.3 to 0.5 ± 0.3), and in PP (1.3 ± 0.4 to 0.7 ± 0.3) 30 AT. There was also a significant reduction in the GI in GG (1.3 ± 0.3 to 0.7 ± 0.4). PPD reduced significantly in GG (2.4 ± 0.6 to 1.9 ± 0.1), and PP (6.7 ± 1.1 to 5.2 ± 0.9) 30 AT. When all the samples were analyzed together, there was a significant reduction in IL-18 (12.9 ± 7.2 to 10.0 ± 3.1). This study showed that non-surgical treatment was effective in reducing GCF levels of IL-18 from inflamed periodontal sites.

O objetivo desse estudo foi avaliar o efeito do tratamento periodontal não-cirúrgico sobre os níveis da IL-18 em sítios inflamados de pacientes com doença periodontal. Foram avaliados 14 pacientes com doença periodontal, sendo 9 pacientes com periodontite crônica generalizada (idade média: 48,8 DP ± 7,4 anos) e 5 pacientes com gengivite (idade média: 43,6 DP ± 11,8 anos). Os pacientes foram divididos nos seguintes grupos: sítios sem perda de inserção nos pacientes com periodontite (GP), sítios com perda de inserção nos pacientes com periodontite (PP) e sítios sem perda de inserção nos pacientes com gengivite (GG). Profundidade de bolsa (PB), nível de inserção (NI), índice de placa (IP) e índice gengival (IG) foram avaliados e amostras do fluido gengival foram coletadas. Os pacientes receberam terapia não-cirúrgica e foram reavaliados 30 dias após tratamento (AT). Houve uma redução significante no IP dos GG (1,0 ± 0,4 para 0,5 ± 0,2), GP (1,2 ± 0,3 para 0,5 ± 0,3) e PP (1,3 ± 0,4 para 0,7 ± 0,3) 30 AT. Também houve uma redução significante no IG do GG (1,3 ± 0,3 para 0,7 ± 0,4). A profundidade de bolsa reduziu no GG (2,4 ± 0,6 para 1,9 ± 0,1) e no PP (6,7 ± 1,1 para 5,2 ± 0,9) 30 AT. Quando todas as amostras foram analisadas juntas, houve uma redução significante do IL-18 (12,9 ± 7,2 para 10,0 ± 3,1). Esse estudo mostrou que a terapia periodontal não-cirúrgica é eficaz em reduzir os níveis de IL-18 no fluido gengival de sítios inflamados.

Amoxicillin/metronidazole or scaling and root planing in the treatment of chronic periodontitis

The aim of the present study was to evaluate the treatment with amoxicillin or metronidazole in comparison to scaling and root planing in the treatment of chronic periodontitis. Randomised clinical trials were searched in the databases MEDLINE, EMBASE, SciELO, Cochrane and Scopus from 1989 to 2010. The search started with 2895 articles.. From this initial number of articles, 10 publications were selected and included in the study according to fixed criteria. Studies included adult patients of both sexes aged between 21 and 80, diagnosed with chronic periodontitis and treated with amoxicillin and/or metronidazole or scaling and root planning. From each article, details were abstracted relating to sample size, design, sex, age, oral hygiene habits, the exposure to drug (doses, schedule), and results such as clinical effect, analysis methods, stratification variables. Conclusion: this meta-analysis showed absence of statistically significant difference between the effects studied.

E-cadherin and CD1a expression in gingival epithelium in periodontal health, disease and post-treatment.

Background: Epithelial integrity is important for maintenance of periodontal health. It is not fully known if non-surgical periodontal therapy is capable of recreating the epithelial barrier in its functional state. Patients and Methods: Sixty-five patients (31 males and 34 females) were included in the study. They were divided into group A (healthy gingiva 16 patients), group B (gingivitis 17 patients), group C (periodontitis 17 patients), and group D (post-treatment 15 patients). Gingival samples were collected and immunohistochemical study was done using E-cadherin and CD1a antibody. Statistical analysis was done using analysis of variance (ANOVA), followed by Tukey-Kramer multiple comparison test for CD1a and Tukey's highly significant difference (HSD) test for E-cadherin. Result: There was a statistically significant difference (P<0.001) in the expression of E-cadherin between healthy (1.846±0.555), gingivitis (1.100±0.994), and periodontitis group (0.700±0.483). Similarly, there was a statistically significant difference (P<0.001) in the expression of CD1a between healthy (75.70±3.09), gingivitis (42.53±3.09), and periodontitis group (29.07±3.08). However, the expression of E-cadherin (1.242±0.653) and CD1a in post-treatment samples (52.18±2.90) was lower with no statistically significant difference when compared to health. Discussion: The significant reduction in E-cadherin and CD1a levels in periodontal disease when compared to health could possibly be a result of invasion by the periodontopathogens and its subsequent sequel. Although, the post-treatment samples showed significant improvement when compared to disease, the reduction in E-cadherin and CD1a levels when compared to gingival health suggests that the epithelial barrier was not yet fully established in its functional state.

Effects of periodontal treatment phase I on birth term and birth weight.

Considering the high prevalence of preterm birth (PTB) and low birth weight (LBW) and their complications as well as the role played by periodontal disease in their incidence and the lack of any report of periodontal therapy on these problems in Iran, the goal of the present research was to determine the effects of periodontal treatment on PLBW incidence among women with moderate or advanced periodontitis who were referred to Javaheri hospital (2004-2005). This clinical trial research was conducted on 30 pregnant women age ranging from 18-35 years old, with moderate or advanced periodontitis. Fifteen subjects randomly underwent the first phase of periodontal treatment including scaling, root planning and the use of 0.2% chlorhexidine mouth rinse for one week. None of these steps were taken for the controls. After necessary follow ups, the effect of periodontal treatment on birth term and birth weight were analyzed statistically. This research was conducted on 30 subjects, 15 controls and 15 cases in study group. In the control group, the observed rate of PLBW was 26.7% whereas among periodontally treated group, phase I, PLBW infant was not observed (P < 0.05). Infants birth weight were (3059.3-389.7) gms in study group and (3371-394.2) gms in the control group and respectively (P < 0.05). Periodontal therapy, phase I, results in a reduction in PLBW incidence rate. Therefore, the application of such a simple method among periodontally diseased pregnant women is recommended.

Clinical and microbial evaluation of dental scaling associated with subgingival minocycline in chronic periodontitis subjects

O objetivo deste estudo randomizado duplo-cego foi avaliar a presença de periodontopatógenos e o comportamento clínico de bolsas periodontais tratadas com raspagem e aplainamento radicular (RAR) associado à minociclina subgengival (MS). Foram incluídos no presente estudo 36 indivíduos de 26 a 60 anos de idade (40,7 ± 9,1), previamente diagnosticados com periodontite crônica. Dezoito indivíduos foram selecionados para o grupo teste (GT), tratado com RAR e MS (novo tratamento), e 18 indivíduos, para o grupo controle (GC), que recebeu RAR e veículo (tratamento convencional). Foram selecionados dois sítios homólogos em cada indivíduo com profundidade de sondagem (PS) > 6 mm para testar a hipótese proposta. Para avaliar o comportamento clínico após o tratamento, a mensuração da PS foi realizada inicialmente e após 90 dias. A avaliação microbiana foi realizada para detecção de 7 periodontopatógenos através de reação em cadeia da polimerase, inicialmente e após 30 e 120 dias. Observou-se redução média de 2,8 e 2,1 mm na PS nos grupos teste e controle, respectivamente. Inicialmente, P. gingivalis foi o microrganismo mais prevalente tanto no GT (65,8%) quanto no GC (48,6%). Após 120 dias, houve redução para 30,8% no GT e 23,1% no GC. Não houve diferenças estatisticamente significativas entre os grupos em relação à PS (teste Wilcoxon - p > 0,05) e presença dos periodontopatógenos (teste Wilcoxon e qui-quadrado - p > 0,05 e teste do sinal - p > 0,01). Os resultados observados demonstraram que o novo tratamento foi tão efetivo quanto o tratamento convencional na redução de periodontopatógenos e de PS em indivíduos com periodontite crônica.
