Treatment of multiple recessions with collagen matrix versus connective tissue: a randomized clinical trial

Abstract The objective of this study was to determine whether collagen matrix (CM) is an alternative to connective tissue graft technique (CTG) in the treatment of multiple gingival recessions (GR). The indication of CM for the treatment of multiple GR is not yet clear. More studies are needed to better understand this treatment modality, as an alternative to CTG. In this single-blind, split-mouth randomized clinical trial, fifteen patients with multiple Miller class I upper GR were selected and randomly assigned to control group (CTG) or test group (CM). Root coverage (RC) and patient-centered outcomes were evaluated at baseline and after 3, 6, and 12 months. A total of 82 GRs were treated. There was no significant difference regarding GR depth (GRD, primary outcome) between CTG (0.5 ± 0.9 mm) and CM groups (0.6 ± 1.0 mm) (p = 0.225). Percentage of RC was 82.14% in CTG and 77.7% in CM. Both groups demonstrated a gain in keratinized tissue width at 12 months (p < 0.05). Dentine hypersensitivity was effectively reduced in both groups. Postoperative pain was significantly higher in the CTG (p = 0.001). Esthetic satisfaction was high for both groups, with no significant difference (p > 0.05) between groups. After 12 months, both surgical treatments were able to promote RC, and GRD was similar in both CTG and CM groups.

Predictors of smoking cessation in smokers with chronic periodontitis: a 24-month study

Abstract The purpose of this 24-month study was to identify predictors of smoking cessation in a cohort of smokers with chronic periodontitis, attending a multidisciplinary smoking cessation program. Of the 286 subjects screened, 116 were included and received non-surgical periodontal treatment and smoking cessation therapy, which consisted of lectures, cognitive behavioral therapy, and pharmacotherapy, according to their individual needs. During initial periodontal treatment, dentists actively motivated the study subjects to stop smoking, using motivational interviewing techniques. Further smoking cessation counseling and support were also provided by the dentists, during periodontal maintenance sessions at 3, 6, 12 and 24 months of follow-up. Smoking status was assessed by means of a structured questionnaire, and was validated by exhaled carbon monoxide (CO) measurements. The Fagerström Test for Cigarette Dependence was used to assess smoking dependence. Of the 61 individuals that remained up to the 24-month examination, 31, 21 and 18 declared that they were not smoking at 3, 12 and 24 months, respectively. Smoking cessation after 24 months was associated with the male gender (OR = 3.77, 95%CI = 1.16-12.30), baseline CO levels less than 10ppm (OR = 5.81, 95%CI 1.76-19.23), not living or working with another smoker (OR = 7.38, 95%CI 1.76-30.98) and a lower mean Fagerström test score (OR = 5.63, 95%CI 1.55-20.43). We concluded that smoking cessation was associated with demographic, smoking history and cigarette dependence variables.

Variação da técnica do túnel para o recobrimento radicular em áreas estéticas: relato de dois casos / Variation of the tunnel technique for root coverage in the aesthetic areas: report of two cases

Este relato de caso descreve uma variação da técnica de túnel, associada ao enxerto de tecido conjuntivo subepitelial, para o recobrimento radicular de retrações gengivais (RG) múltiplas adjacentes em área estética. Este procedimento foi utilizado em dois casos clínicos distintos com o objetivo de conseguir recobrimento radicular, diminuição de hipersensibilidade dentinária e aumento da faixa de gengiva inserida. No caso 1, havia RGs, Classe I de Miller, nos dentes 11, 21 e 22, e todos os objetivos foram alcançados. No caso 2, as RGs eram Classe III de Miller nos dentes 11 e 21, e houve aumento da faixa de gengiva inserida, ganho de inserção clínica e recobrimento radicular parcial em ambos os dentes. A variação da técnica de túnel associada ao enxerto de tecido conjuntivo subepitelial pode ser uma alternativa viável para o tratamento das RGs Classes I e III de Miller, e sua utilização pode melhorar o padrão estético, promover ganho de inserção clínica, aumento da faixa de gengiva inserida e recobrimento radicular

Cessação de tabagismo em fumantes com periodontite crônica / Tabacco use cessation in chronic periodontitis smokers

O tabagismo é o mais importante fator de risco de diversas doenças crônicas, incluindo a periodontite. Embora cirurgiões-dentistas apresentem potencial para ajudar seus pacientes fumantes a abandonar o vicio, o papel do dentista na cessação do tabagismo ainda não está totalmente esclarecido. O objetivo deste estudo prospectivo de 12 meses foi verificar o efeito de um programa antitabágico multidisciplinar na cessação de tabagismo em fumantes com periodontite. Duzentos e um (201) sujeitos foram triados e 93 foram incluídos e receberam tratamento periodontal não-cirúrgico e terapia antitabágica. Durante o tratamento periodontal, os dentistas motivaram ativamente os participantes a pararem de fumar, usando técnicas de entrevista motivacional. Aconselhamento e suporte adicionais foram fornecidos durante as visitas de manutenção após 3, 6 e 12 meses do término do tratamento periodontal. A condição de tabagista foi avaliada por meio de um questionário estruturado e foi validada pela mensuração de monóxido de carbono expirado (CO). Dentre os 52 indivíduos que permaneceram até o exame de 12 meses, 22 (42,31%), 17 (32,69%) e 17 (32,69%) não estavam fumando após 3, 6 e 12 meses, respectivamente. Concluiu-se que a terapia antitabágica realizada por uma equipe multidisciplinar que inclui dentistas resultou em alta taxa de cessação de tabagismo

Smoking is the leading risk factor of several chronic diseases, including periodontitis. Although it is acknowledged that dentists have potential to help smoking patients to quit, their role in tobacco control is not completely defined. The aim of this prospective 12-month study was to evaluate the effect of a multidisciplinary smoking cessation program in quitting smoking in subjects with periodontal disease. Two-hundred and one (201) subjects were screened, and 93 were included and received non-surgical periodontal treatment and smoking cessation therapy. During initial periodontal treatment, dentists actively motivated the study subjects to stop smoking, using motivational interviewing techniques. Further smoking cessation counseling and support were also provided by the dentists during periodontal maintenance sessions at 3, 6 and 12 months of follow-up. Smoking status was assessed by means of a structured questionnaire, and it was validated by exhaled carbon monoxide (CO) measurements. Among the 52 individuals that remained up to the 12-months examination, 22 (42.31%), 17 (32.69%) and 17 (32.69%) were not smoking at 3, 6 and 12 months, respectively. It is concluded that smoking cessation therapy performed by a multidisciplinary team including dentists resulted in high quit rates

Smoking and periodontal tissues: a review

The impact of smoking on general health has been widely studied and is directly related to several important medical problems including cancer, low birth weight, and pulmonary and cardiovascular disease. In the past 25 years, there has also been an increasing awareness of the role of cigarette consumption in oral health problems such as periodontal disease. Smoking is considered the major risk factor in the prevalence, extent and severity of periodontal diseases. This article will discuss the available evidence and provide the reader with an overview of the impact of smoking and its cessation on the pathogenesis and treatment of periodontal diseases.

O papel do cirurgião-dentista no abandono do hábito do fumo / The role of the dental team at quitting smoking

O fumo representa a maior causa de morte e invalidez passível de prevenção. É também o maior fator de risco na prevalência, extensão e gravidade das doenças periodontais. O abandono deste vício por meio de estratégias empregadas por profissionais da área da saúde é considerado uma ação extremamente efetiva. As três técnicas: aconselhamento, terapia de reposição de nicotina e terapia medicamentosa são as mais utilizadas para a terapia antitabágica pela praticidade, segurança e grau de eficiência. O objetivo desta revisão de literatura é descrever estas três técnicas, bem como suas taxas de sucesso e a importância do cirurgião-dentista em auxiliar os pacientes fumantes no abandono deste hábito.

Smoking is the largest single preventable cause of mortality and morbidity worldwide. It is also the most prominent risk factor for the prevalence, extent and severity of periodontal diseases. The cessation of this habit through anti-smoking strategies employed by health care professionalsis considered an extremely effective action. Three smoking cessation techniques: counseling, nicotine replacement therapy, and drug therapy are the ones most employed by their simplicity, safety and efficiency. The aim of this literature review is to describe these techniques, their success rates, and to highlight the importance of the dental team at assisting patients to quit smokin.
