Bruxism is defined as a repetitive activity of the masticatory muscles, characterized by clenching and grinding of the teeth, which may present with trapping or sliding of the jaw. It is considered a phenomenon regulated mainly by the central nervous system and influenced by peripheral factors. It has two distinct circadian manifestations: it can occur during sleep - indicated as nocturnal bruxism - or during wakefulness - indicated as diurnal bruxism. The quality of sleep of the naval health personnel on active duty of the Secretariat of the Navy-Mexican Navy, who are doing their residency at the naval medical center, is affected because at this stage of training they are forced to sleep less than six hours a day in order to fulfill their academic obligations. The objective of this research was to determine the relationship between bruxism and sleep quality in residents of the various medical specialties at the Naval Medical Center. It is expected to find an association between self-reported bruxism and sleep quality in CEMENAV residents, through self-reported digital questionnaires likers; self-reported bruxism questionnaire and Pittsburgh sleep quality index. The sample consisted of 104 residents aged 25 to 44 years; 64 men and 40 women. This study is cross-sectional, prospective and observational. The variables included in this study were bruxism and sleep quality. Statistical analysis was performed by applying Fisher's exact test to determine the distribution of the sample; the Kolmogorov-Smirnov test was used; the population was described using frequency tables, trend measures and dispersion measures, as well as an association between the main variables. The data were analyzed in the graphpad prism software. The findings were found to be statistically significant, confirming the hypothesis and strategies to follow to improve this situation will be analyzed.
