Evaluation by app in smartphones of awake bruxism at the return of presential classes in two university centers

Abstract

Background. The return to normality post-pandemic brought some inconveniences to the population, especially students. To evaluate the frequency of awake bruxism behaviors through the use of an app on smartphones in dental students returning to presential classes. Awake bruxism was evaluated with the creation of an app that according to the authors evaluates: relaxed jaw muscles, dental contact, jaw effort, clenching teeth and teeth grinding, 5 frequent oral conditions in the population. The frequency of awake/daytime bruxism (AB) in healthy individuals when comparing other populations with possible risk factors for additive bruxism (psychological factors, depression, suicide delusions, etc.), evaluating consequent clinical signs (fatigue, muscle pain, attritions and dental openings). Methods: The sample of three hundred (n=300) young adults legally enrolled in two Ecuadorian universities, the sample was selected among fifth, sixth, seventh, eighth and ninth semester students legally enrolled and who are attending Faculty of Dentistry classes in 2 different cities (Quito and Guayaquil). The app was configured to provide 20 alerts during the day x seven days a week, in real time. Results. The study obtained 95% reliability and 5% error in research, was used. The relaxation condition was present in all users, but 40% of the alerts were associated with jaw and tooth discomfort, 39% corresponded to the discomfort of mandibular clenching, and 24% corresponded to tooth contact. A direct significant association was found between the state of relaxation and nonrelaxation, with a high probability of reports related to nonrelaxation (p ≤ 0.05). Conclusions: Awake bruxism with the app was evaluated, identifying 5 behaviors such as: relaxed mandibular muscles, dental contact, mandibular effort, clenching and grinding teeth, frequent conditions in the population; reporting a state of mandibular relaxation, there is a high probability that a condition of nonrelaxation would be reported (p≤0.05).
