Effect of gingivitis treatment on the breath of chronic periodontitis patients.

PURPOSE: The present study assessed halitosis after treatment of gingivitis by using different diagnostic modalities. MATERIALS AND METHODS: A total of 27 patients (47 ± 7 years old; 14 women, 13 men) diagnosed with chronic periodontitis underwent supragingival mechanical debridement (day 0). Measurement of volatile sulfur compounds (VSC), visual analogue scale (VAS) and organoleptic assessment, visible plaque index (VPI) and gingival bleeding index (GBI) were obtained at baseline (prior to treatment of gingivitis) and then after 30, 90, and 180 days. The Friedman test was used to compare outcome data at days 0, 30, 90, and 180. Post-hoc comparison (tongue cleaning and non-cleaning) was performed using the Student t test for VSC and VAS and the Mann-Whitney test for organoleptic measurements. The level of significance was set at 5%. RESULTS: VSC and VAS means (days 0 and 180) were, respectively, 463.41 ppb (± 496.12 ppb) and 245.96 ppb (± 301.51 ppb) and 6.28 cm (± 2.23 cm) and 5.03 cm (± 2.01 cm). The frequency of high organoleptic scores (3 to 5) declined from 96.29% (day 0) to 81.48% (day 30), with a reduction of around 50% at day 180. Post-hoc comparison did not reveal any significant differences between the indicators analysed. CONCLUSION: Supragingival plaque control reduced halitosis in patients with periodontitis, but tongue cleaning vs no tongue cleaning did not yield different results.

The Impact of Omega-3 Supplements on Non-Surgical Periodontal Therapy: A Systematic Review.

AIM: This systematic review examined the additional effect of taking omega-3 supplements on periodontal therapy. METHODS: The focused question was "What is the possible effect of omega-3 supplementation concomitant to non-surgical periodontal therapy on clinical periodontal parameters?" Databases Cochrane, Embase, Google Scholar, PubMed, and Web of Science (January-July 2021) were searched to identify appropriate studies. Randomized clinical trials (RCT) about non-surgical therapy with omega-3 supplementation, with at least 3 months of supplementation period were included. Cochrane risk of bias tool version 2 and Grading of Recommendations Assessment, Development, and Evaluation were used. RESULTS: A total of 1556 studies were found, of which eight studies met the inclusion criteria. All eight studies evaluated periodontal probing depth and clinical attachment loss; plaque and gingival inflammation were evaluated in seven studies. High variety of omega-3 dosage, different study lengths, questionable results from periodontal therapy (including test and control groups), high risk of bias and moderate quality of evidence prevented a satisfactory conclusion regarding the benefits of omega-3 supplementation. The studies' high heterogeneity avoided meta-analysis. CONCLUSION: Notwithstanding all limitations, the promising effects of omega-3 supplementation presented in two six-month studies encourage performing RCT with better-defined treatment protocols and greater methodological rigor.

Effect of supragingival plaque control in smokers and never-smokers: 6-month evaluation of patients with periodontitis.

BACKGROUND: The effect of supragingival plaque control on clinical signs of periodontitis is controversial, particularly when smoking habits are considered. This study evaluated the clinical effects of supragingival plaque control on clinical signs of periodontitis in smokers and never-smokers. METHODS: The following data were collected for 25 never-smokers and 25 smokers at baseline and 30, 90, and 180 days: visible plaque index (VPI), gingival bleeding index (GBI), bleeding on probing (BOP), periodontal probing depth (PD), and clinical attachment loss (CAL). After baseline examinations, supragingival scaling was performed. Oral hygiene practices were reinforced and reevaluated weekly during the experimental period. Linear models adjusted for clustering of observations within individuals were used for statistical analysis. RESULTS: Reductions in VPI were significant for both groups, with no intergroup differences. GBI at baseline was similar between groups, and at 30, 90, and 180 days, smokers had a lower GBI than never-smokers. Significant reductions were observed in PD for shallow (1 to 3 mm), moderate (4 to 5 mm), and deep sites (> or = 6 mm) in both groups. CAL was significantly greater in smokers throughout the study, but gains in attachment were similar for both groups (0.71 to 1.00 mm). BOP reductions were similar in both groups. CONCLUSIONS: Supragingival plaque control resulted in significant changes in clinical parameters associated with gingivitis and periodontitis. Smoking did not affect results, regardless of initial PD.

Response of molars and non-molars to a strict supragingival control in periodontal patients.

The posterior position in the arches is one of the factors that underlies the poor prognosis of molar teeth (M). It is speculated that M do not benefit from the oral hygiene routine as well as non-molars (NM) do. This study evaluated the response of M and NM to supragingival control during a 6-month period in 25 smokers (S) and 25 never-smokers (NS) with moderate-to-severe periodontitis. One calibrated examiner assessed visible plaque (VPI) and gingival bleeding (GBI) indexes, periodontal probing depth (PPD), bleeding on probing (BOP), and clinical attachment loss (CAL) at days 0 (baseline), 30 and 180. At baseline, M showed significantly higher mean values of VPI (p = 0.017) and PPD (p < 0.001) compared with NM; CAL was also greater in M (p < 0.001) and was affected by smoking (p = 0.007). The reductions obtained for periodontal indicators at day 180 showed similar responses between M and NM. For CAL, M (NS 0.57 ± 0.50; S 0.67 ± 0.64) and NM (NS 0.38 ± 0.23; S 0.50 ± 0.33) reached an almost significant difference (p = 0.05). Smoking did not influence the response to treatment. Multilevel analysis revealed that, only for PDD reductions, the interaction between sites, teeth and patient was significant (p < 0.001). It was concluded that M benefit from an adequate regimen of supragingival biofilm control; therefore, supragingival condition should be considered in the prognosis of molar teeth.

Efeito do controle do biofilme supragengival na condição periodontal de pacientes tabagistas: uma revisão sistemática / Effect of supragingival plaque control on periodontal disease in smokers: a systematic review

Objetivo: avaliar, por meio de uma revisão sistemática da literatura, se o controle do biofilme supragengival, em pacientes fumantes, é capaz de alterar os critérios clínicos e microbiológicos associados à periodontites. Metodologia: a estratégia de busca envolveu o uso de bases de dados eletrônicos: MEDLINE e Cochrane Oral Health Group, entre 1965 e Janeiro de 2009. As palavras-chave utilizadas no MEDLINE foram: supragingival plaque control AND (subgingival OR debridement OR scaling and root planing OR non surgical OR oral hygiene OR periodontitis OR gingivitis OR plaque subgingival OR lost attachment OR probing pocket depth OR bleeding).Nessa busca foram localizadas 307 referências bibliográficas, contemplando os mais variados tipos de estudos. No Cochrane as palavras-chave aplicadas foram: supragingival plaque control AND oral hygiene, sendo obtidas 137 referências. A aplicação de critérios de inclusão permitiu que 4 estudos fossem avaliados na íntegra: 3 ensaios clínicos com seleção randômica de sítios experimentais e 1 ensaio clínico sem randomização. Resultados: dos estudos avaliados, 2 avaliaram somente a intervenção supragengival e 2avaliaram, também, a intervenção subgengival. Pôde-se observar que o controle supragengival, como intervenção única, foi capaz de determinar redução dos indicadores clínicos e microbiológicos periodontais, sendo os melhores resultados condicionados a um adequado programa de controle do biofilme supragengival. Conclusão: o estudo mostrou que o efeito do controle de biofilme supragengival em pacientes tabagistas é capaz de melhorar significativamente os indicadores clínicos e microbiológicos associados à gengivite e periodontite.

Aim: to conduct a systematic review of the literature to assess whether supragingivalplaque control is able to change clinical and microbiological markers associated with periodontal disease in smokers. Methodology: articles published between 1965 and January 2009 and indexed in the MEDLINE and Cochrane Oral Health Group databases were browsed. The following keywords were used on MEDLINE: supragingival plaque control AND (subgingival OR debridement OR scaling and root planing OR non surgical OR oral hygiene OR periodontitis OR gingivitis OR plaque subgingival OR lost attachment OR probing pocket depth OR bleeding);the search on MEDLINE yielded 307 references, including different types of studies. On Cochrane, the keywords employed were supragingival plaque control AND oral hygiene; this search yielded 137 studies. After application of inclusion criteria, four studies were selected for full-text review: three clinical trials with randomly selected experimental sites and one nonrandomized clinical trial. Results: of the four studies reviewed, two assessed the effects of supragingival plaque control alone, whereas the other two assessed both supragingival and subgingival interventions.It was possible to observe that supragingival plaque control alone was able to reduce clinical and microbiological indicators associated with periodontal disease, and that the best results were obtained after an adequate supragingival plaque control regimen. Conclusion: our study showed that supragingival plaque control is able to significantly improve clinical and microbiological markers associated with gingivitis and periodontitis in smokers.

O efeito do controle da placa supragengival sobre parâmetros clínicos periodontais em pacientes que fumam e que nunca fumaram / The effect of supragingival plaque control on the clinical parameters in periodontal patients smokers or never-smokers

O presente ensaio clínico comparou a resposta dos parâmetros clínicos supragengivais e subgengivais durante o controle da placa supragengival em 25 pacientes que fumam (F), com média de 46 anos de idade (variando de 33 - 57), 19,44 ± 11,63 cigarros por dia durante 24,84 ± 8,50 anos, e 25 pacientes que nunca fumaram (NF), com média de 46,80 anos de idade (variando de 34 - 59). Os exames, baseline, 30, 90 e 180 dias, foram realizados por uma examinadora calibrada, que avaliou o Índice de Placa Visível (IPV) e de Sangramento Gengival (ISG), Profundidade de Sondagem (PS), Nível de Inserção Clínica (NIC) e Sangramento Subgengival (SS). O controle da placa supragengival consistiu inicialmente de raspagem, alisamento e polimento coronário, limitado ao ambiente supragengival seguido por sessões semanais, por um período de seis meses, de instrução e monitoramento individualizado do controle de placa. As médias por indivíduo foram analisados pelo Teste de Friedman e pelo Teste de U de Mann-Whitney (p≤0,05). Foram observadas reduções significativas em todos os parâmetros para fumantes e nunca fumantes. O IPV reduziu de 90,96% para 8,29% (NF) e de 88,09% para 6,10% (F), sem diferenças entre os grupos. O ISG foi reduzido de 78,95% para 2,12% e de 70,48% para 0,28% nos mesmos grupos, porém com diferenças significativas entre os grupos a partir dos 30 dias. Reduções do SS também foram significativas, para nunca fumantes de 94,05% para 21,75%, e em fumantes de 94,05% para 23,71%, sem diferenças entre os grupos. Significativas reduções na PS foram observadas para nunca fumantes de 3,67mm para 2,60mm e em fumantes de 3,93mm para 2,77mm. Alterações no NIC foram significativas, de 3,43mm para 3,02mm (NF) e de 4,20mm para 3,68mm(F). Houve uma significativa redução do percentual de sítios com PS inicial maior ou igual a 7mm e um aumento no percentual de sítios de 0-3mm. Conclui-se que o controle de placa supragengival executado reduziu significativamente os sinais clínicos da doença periodontal em pacientes que fumam e que nunca fumaram.

Recobrimento radicular múltiplo: relato de caso / Multiple root coverage: case report

A literatura mostra uma variedade de técnicas cirúrgicas destinadas ao tratamento das recessöes gengivais, em grande parte relacionadas as recessöes localizadas. Contudo, para o tratamento de recessöes múltiplas, não säo descritas técnicas específicas, adotando-se as mesmas aplicadas as recessões localizadas, com a utilizaçäo de mais um procedimento cirúrgico. O artigo relata um caso de recobrimento radicular em múltiplos elementos com a realizaçäo de um procedimento cirúrgico único. Embora os defeitos apresentassem diferentes dimensões de altura e largura, o resultado mostrou-se bastante satisfatório, tendo sido obtido o recobrimento completo das recessöes. Ao final do período de observaçäo (um ano), constatou-se a estabilidade do resultado inicial e até uma melhor adaptaçäo cervical (creep attachment), conclui-se que a técnica pode ser empregada com sucesso nos casos de recessöes múltiplas
