Background Ozone is a molecule that plays an important role in dentistry, specially for wound healing. The aim of the present study was to clinically and immunologically evaluate the effect of ozonated oil on the healing of palatal wounds. Methods This is a prospective, longitudinal, triple‐blind, randomized, placebo‐controlled clinical trial. The groups were divided as follows: Test group (n = 14): after removal of the free gingival graft (FGG), the palatal wound was treated with ozonized seed sunflower oil with a peroxide index between 510 and 625 meq O2/kg; Control group (n = 14): after removal of the FGG, the palatal wound was treated with non‐ozonated sunflower oil (placebo). The treatments were applied three times a day, for 7 days. Results There were no significant differences in the measurements of wound area (mm2) between the test and control groups in the different periods evaluated (0, 3, 7, and 14 days; p > 0.05). The intra‐group analysis showed a significant decrease in wound size over the course of days (0, 3, 7, and 14 days; p < 0.05). Vascular endothelial growth factor (VEGF; pg/mL) presented a significant reduction at 7 days (p < 0.05) compared to day 3 in the test group (p < 0.05). There was a statistical difference for malondialdehyde (MDA; pg/mL) in the test group between 3 and 7 days post‐treatment (p < 0.05) and between test and control groups on the 7th day (p < 0.05). Conclusions The application of highly ozonated sunflower oil did not improve the remaining scar area of the palate, decreasing the VEGF and increasing the oxidative stress marker MDA.

Introduction The COVID-19 pandemic has led to an interruption in work activities in various sectors, generating an economic crisis and a high rate of unemployment worldwide. Objective To assess the behavior and perceptions of Brazilian dentists about the COVID-19 pandemic and to verify its impact on the routine of dental care. Material and method The electronic questionnaire was disseminated through social networks from July to November/2020. The representativeness for the study sample was calculated, generating a sample calculation of 385 dentists. Result In total, 318 dentists (82.6%) from all regions of Brazil answered the questionnaire, being 112 men (35.2%) and 206 women (64.8%). Most of the interviewees, that is, 249 dentists (78.3%) reported working in private offices or clinics. Of the interviewees, 26 (8.8%) tested positive for COVID-19 and another 10 (3.1%) had symptoms of the disease, but did not take the test. No interviewees reported having been hospitalized due to the disease. During the period of application of the questionnaire, 235 respondents were attending routine and emergency patients (73.9%). Only 174 (54.7%) reported feeling safe with the use of personal protective equipment. Most interviewees declared that they did not have a financial reserve for the interruption of work activities (54.7%). Conclusion The COVID-19 pandemic has had a major impact on dentistry, and better financial planning, in addition to constant reinforcement of biosafety care, which is essential for professionals in the healthcare area, can help to protect them and maintain their professional practice in times of pandemic and uncertainty.
