The transmission of viruses between species and the emergence of viral pandemics are threats to public health and with catastrophic aftermath for the population. Objective: The objective of this research was evaluated actions of Brazilian dentists concerning covid-19 during the first wave of the pandemic. Material and methods: The survey was conducted with a web-based questionnaire, from 8th July to 8th August 2020. The participants answered questions about socio-demographic factors, followed by actions towards the covid-19, that include service offered in the pandemic period, personal protective equipment (PPE), mode of prevention, emergency with a suspect case and urgency with a confirmed case. All data were submitted to descriptive and inferential statistics with a 5% significance level. Results: A total of 393 participants were recruited, 27.7% men and 72.3% women with a median age of 30 years (21 – 61). About service offered in the pandemic period 53.4 % of the participants answered to operate as a “usual service with a longer period between patients”. Professionals who do not work in universities have adopted actions of “increasing the time between dental appointments” (p = 0.04) or “operate as usual” (p = 0,02). Nearly PPE, 48,9% wore an N-95 mask. Regarding mode of prevention, older and more experienced dentists adopted more preventive measures than younger and more experienced dentists (p > 0.05), in addition, men choose pre-procedural mouthwash with PVPI more than women (p = 0.014). Likewise, those who work at universities also choose pre-procedural mouthwash with PVPI more than those who do not work at universities (p = 0.004). The action regarding urgency and emergency care varied according to the educational level of the participant. Conclusion: It is important to emphasize that during this moment of uncertainty, it is necessary to be constantly aware of new scientific evidence. While generally accepting of federal and state recommendations, respondents seemed to desire more guidance during the initial phase of the pandemic. Some participants’ actions towards covid-19 were divergences from the recommendations proposed by the regulatory agencies.
