A randomized controlled parallel clinical trial was conducted to evaluate the efficacy of the association of 1.23% topical professional acidulated phosphate fluoride (APF) gel with oral hygiene and dietary instructions on the arrest of active non-cavitated lesions in permanent, mixed, and temporary dentition in children between 3 and 12 years of age. Ninety-eight caries-active children were randomly divided into two groups: a fluoride gel group (n = 49) and a non-fluoridated gel group (n = 49). Each group received up to eight weekly applications of gel, weekly professional toothbrushing with oral hygiene instructions and dietary counselling. Caries lesions were assessed qualitatively through visual-tactile criteria performed in three stages: initial, intermediate, and final. Regression models were applied to identify risk indicators for caries control. Between-group comparison regarding the time taken to arrest the lesions was performed using Chi-squared and Fisher's exact tests. Seventeen children did not receive the allocated intervention, and one was lost to follow-up (n = 80). There was no difference between the control and placebo groups regarding the time to the arrest of the lesion (p >.05). The treatments showed similar results without significant statistical difference (p = 0.33; 95%CI: 0.32-1.48). No adverse effects were observed. It can be concluded that no additional effect of the association of 1.23% APF gel with oral hygiene using fluoride dentifrice and dietary instructions on the arrest of active non-cavitated lesions could be established. We can also confirm the importance of toothbrushing frequency and, consequently, the visible plaque reduction in the control of caries activity. RBR-37V5S3

The aim of this study was to compare the acquired enamel pellicle protein profile of professional wine tasters with mild and moderate erosive tooth wear. Twelve professional wine tasters participated (3 from a low tooth wear group; 9 from a high tooth wear group). Acquired enamel pellicle samples were collected and processed for proteomic analysis (nLC-ESI-MS/MS). The acquired enamel pellicle proteomic profile was different between the groups. The proteins found exclusively in the low

Visible plaque and gingivitis reduced in a sample of patients treated under integrated dental care. Some predictors may determine for which patients the treatment may be maximize and those who will need greater efforts to achieve the therapeutic goal for oral hygiene.

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.
