Knowledge and attitudes related to erosive tooth wear of professional wine tasters: a cross-sectional study / Conhecimentos e atitudes relacionadas ao desgaste dentário erosivo de provadores de vinho profissionais: um estudo transversal

Objective: this study aimed to evaluate knowledge and attitudes of professional wine tasters about erosive tooth wear. Material and Methods: two questionnaires were applied to 56 wine tasters during the 25th National Evaluation of Wines - Safra 2017 in Bento Gonçalves, Rio Grande do Sul. Descriptive data analysis and the Fisher's exact test were performed (p < 0.05). Results: for the analysis, 56 volunteers aged 25-76 years were included. Most of the volunteers reported attending dentist once a year (55.35%) and their teeth become sorer after ingesting liquids or acid foods (32.14%) over time. The majority (82.14%) believe wine tasting may have teeth effects and have already heard about erosive tooth wear (51.78%). However, when asked about symptomatology, more than half (53.57%) reported not to know. Brushing teeth immediately after ingesting something (37.5%) and increasing the brushing frequency (33.92%) were the most cited treatment options. The habit of using mouthwash solutions was significantly associated with the professionals age (p = 0.039). Conclusion: the volunteers reported a high intake of acid substances and, although most of them reported to consult dentist regularly and have already heard about erosive tooth wear, knowledge about this condition is still limited among these professionals.

Objetivo: o objetivo desse estudo foi avaliar o conhecimento e as atitudes de provadores de vinho profissionais relacionadas ao desgaste dentário erosivo. Material e Métodos: dois questionários foram aplicados a 56 provadores de vinho durante a 25ª Avaliação Nacional de Vinhos - Safra 2017 no município de Bento Gonçalves, Rio Grande do Sul. Foi realizada a análise descritiva dos dados e o teste Exato de Fisher (p < 0.05). Resultados: na análise foram incluídos 56 voluntários com idade entre 25 e 76 anos. A maioria dos voluntários relatou frequentar o dentista uma vez por ano (55,35%) e que seus dentes, com o passar do tempo, tornaram-se mais doloridos ao ingerir líquidos ou alimentos ácidos (32,14%). Mais da metade (82,14%) acreditam que as provas de vinho podem causar algum efeito sobre os dentes e já ouviram falar em desgaste dentário erosivo (51,78%). Porém, quando questionados sobre a sintomatologia, a maioria (53,57%) afirmou não ter conhecimento. Escovar os dentes imediatamente após ingerir algo (37,5%) e aumentar a frequência de escovação (33,92%) foram as opções mais compreendidas como tratamento. Utilizar soluções para bochecho esteve significativamente associado à idade dos profissionais (p=0,039). Conclusão: provadores de vinho profissionais relataram alta ingestão de substâncias ácidas e, embora a maioria consulte pelo menos uma vez por ano o dentista e já tenha ouvido falar a respeito do desgaste dentário erosivo, o conhecimento sobre essa condição ainda é limitado entre esses profissionais.

Influence of Isolation Technique on the Survival of Resin-Modified Glass-Ionomer Restorations in Primary Molars: A 9-Months Randomized Controlled Trial

ABSTRACT Objective: To compare the survival of occlusal and occlusal-proximal restorations performed with resin-modified glass-ionomer cement (RMGIC) in deciduous molars using rubber dam and cotton rolls isolation. Material and Methods: Ninety-two patients were included and 200 deciduous molars with cavitated occlusal or occlusoproximal dentin caries lesions were randomized into two groups: cotton rolls (n = 100) and rubber dam (n = 100) and RMGIC restorations were placed. At baseline and in the follow-up visit, presence, severity and activity of caries lesions were registered. Two independent, blinded examiners evaluated the treated teeth clinically using the USPHS criteria and radiographically after 9 months. Descriptive analysis, survival curve (log-rank test) and Cox regression were performed to assess risk factors related to failure. Results: Out of the 179 teeth (92 cotton rolls group and 87 rubber dam group) evaluated at 9-month follow-up period. No lesion progression was observed radiographically. The overall treatment success rate was 85.47% (83.47% for cotton rolls and 87.35 rubber dam group). No significant difference between isolation methods was observed in the log-rank test (p = 0.16). Cox regression showed no risk factors related to failure. Conclusion: No difference was found in the survival of occlusal and occlusal-proximal restorations performed with RMGIC in deciduous molars using a rubber dam and cotton rolls isolation after a 9-month follow-up period.
