Abstract
Objective: Correlate the hydration routine and level of knowledge of dentistry interns at a Rondônia private educational institution with its consequences. Methods: Quantitative research, realized in the second semester of 2020 at a private institution from Porto Velho, Rondônia. The data were collected through the application of a questionnaire involving 50 trainees of the dentistry course, enrolled between the sixth and eighth term. Results: It can be seen that about the ingestion of water 50% of the interns claimed to drink between 1 and 1,5 liter of liquid per day, below the OMS recommendation that indicates at least three liters of electrolyte replacement, hydration. When asked about the reasons for forgetting hydration, the participants mostly claimed that the workload followed by reduced pause moments is the main cause. Conclusion: Although most of the interviews know the importance of hydration, most do not perform properly. In that way, the problem is not in the lack of awareness, but rather in the lack of knowledge about the consequences of dehydration and the damage, it can cause.
