Abstract

Objective: Sleep is a complex behaviour phenomenon essential for physical and mental health and for the body to restore itself. It can be affected by structural alterations caused by sleep bruxism. The aim of this study was to verify the effects of sleep bruxism on the sleep architecture parameters proposed by the American Academy of Sleep Medicine. Design: The sample comprised 90 individuals, between the ages of 18 and 45 years, divided into two groups: with sleep bruxism (n = 45) and without sleep bruxism (n = 45). The individuals were paired by age, gender and body mass index: a polysomnography was performed at night. Results: Statistically significant differences were found between (P <= 0.05) individuals with sleep bruxism and individuals without sleep bruxism during total sleep time (P = 0.00), non-rapid eye movement (NREM) total sleep time (P = 0.03), NREM sleep time stage 3 (P = 0.03), NREM sleep latency (P = 0.05), sleep efficiency (P = 0.05), and index of microarousals (P = 0.04). Conclusions: Sleep bruxism impairs the architecture of nocturnal sleep, interfering with total sleep time, NREM sleep latency, and sleep efficiency. (AU)
