Studies have demonstrated several etiological factors for gingival recession such as periodontitis, traumatic toothbrushing, use of oral piercing, and past orthodontic therapy, among others. It might not be possible to identify and quantify the influence of each factor, and gingival recession at some sites may be the result of the combination of these factors. Gingival recession affects individuals at all ages, with prevalence increasing as time passes. The aim of this study was to observe whether there is correlation between gingival thickness and gingival recession. Fifty-five subjects of both genders aged 18-35 years participated in the study. The volunteers were under treatment at the School of Dentistry of the Federal University of Rio Grande do Sul. Buccal gingival thickness was measured on incisors, canines and bicuspids, under anesthesia, following inclusion and exc...

Microscopic measurements are the most frequent methods in periodontal studies with animals, but have limited capacity to identify bone levels associated with both healthy tissues and periodontal disease. Ligatures were placed in the maxillary left second molars of 10 male 60-day-old Wistar rats for 30 days. Left and right maxillary sides of 5 rats were processed for histologic analysis (H), sectioned buccolingually, and stained with HE. The maxillae of the other 5 rats were defleshed and used for morphometric analysis (M). Histometric measurements from the cementoenamel junction to the bone crest were performed. Standardized photographs were used for morphometric analysis. The t test was used for dependent or independent samples (alpha = 0.05%). Distances from cementoenamel junction to bone crest were 0.95 ± 0.25 and 1.07 ± 0.30 mm for H and M, respectively. Buccal measurement...

Essa abordagem baseia-se em valer-se da melhor evidência disponível para abordar clinicamente pacientes e populações. Para que a adoção de uma prática baseada em evidências seja realidade, a formação profissional necessita contemplar não só o conhecimento de características de qualidade de evidência, mas também permitir ao acadêmico a experiência prática de procurar a base científica para a sua tomada de decisão clínica. a disciplina dePeriodontia da Universidade Federal do Rio Grande do Sul, há alguns anos vem procurando adequar-se a esse novo paradigma. Nesse sentido, tem modificado suas práticas didáticas. O objetivo do presente artigo é relatar uma experiência didática envolvendo odontologia baseada em evidências.

A engenharia tecidual é um campo interdisciplinar que aplica princípios da engenharia, biologia e ciências clínicas para o desenvolvimento de substitutos biológicos que possam manter, restaurar, ou melhorar a função de órgãos e tecidos. Essa nova ciência está embasada em três pontos: células, matrizes biocompatíveis e moléculas bioativas responsáveis pelos sinais morfogênicos. As células usualmente empregadas são as células-tronco. Buscamos neste artigo atualizar os cirurgiões dentistas no conceito de engenharia tecidual e em que contesto está sendo pesquisada na Odontologia, mais especificamente nas áreas que envolvem periodonto e polpa.

This study aimed to determine predictors of changes in visible plaque (VP) and gingival bleeding (GB) during integrated dental care. A retrospective longitudinal study was conducted by a census of patients receiving integrated dental care in a general clinical practice ambulatory at the Federal University of Rio Grande do Sul (Brazil). The sample comprised 91 charts of patients attended over a 6-months period. Gender, age, patient's main complaint, oral hygiene pattern, and clinical data were recorded from charts for the last two dental visits in the ambulatory. Changes in VP and GB were modeled by multiple linear regression and beta coefficients (b) were reported. The mean follow-up time was 13 months. Significant reductions in VP (32.8 ± 27.9 to 17.4 ± 19.4%; p < 0.001) and GB (27.1 ...

A crossover, randomized, double-blind clinical trial was conducted to evaluate the effect of two chlorhexidine solutions against supra- and subgingival biofilm formation (NCT#02656251). Thirty-five participants were randomized and asked to rinse twice daily with 15 ml of an alcohol-containing 0.12% chlorhexidine solution, an alcohol-free 0.12% chlorhexidine solution, or placebo. The study was conducted in three experimental periods of 4 days each, with a 10-day washout between the periods. All the experimental periods followed the same protocol, except that the solutions were switched. Biofilm distribution was evaluated every 24 hours by the Plaque-Free Zone Index, during 96 hours. Adverse events were self-reported and sensory evaluation was performed using a hedonic scale. Compared to the placebo, the...
