Prevalence of bruxism and its association with other sleep disorders in an Egyptian population: A cross-sectional study
Objectives: The aim of this study was to quantify the prevalence of bruxism in a sample of the Egyptian population and to identify associations between sleep bruxism (SB), obstructive sleep apnea (OSA) and gastro-esophageal reflux disease (GERD).
Methods: This cross-sectional study was conducted on 991 subjects within the age range of 18-70. A questionnaire based on the diagnostic criteria of the American Academy of Sleep Medicine and dental clinical examinations were carried out to diagnose bruxism. The STOP-Bang assessment tool was used to identify the risk of OSA; and the GERDQ questionnaire was used to assess the GERD score of individuals. Statistical analysis was performed to compare the risk and severity of OSA and GERD in bruxers versus in non-bruxers.
Results: Within the surveyed population, the prevalence of bruxism was found to be 25.6%, 62.2% of which suffering from sleep bruxism. There was no statistically significant difference between mean OSA scores in subjects with SB and subjects without. The mean (SD) values were 1.43 (1.56) and 1.35 (1.49) for the two groups, respectively (p-value = 0.484). Bruxers showed significantly higher mean GERD scores than non-bruxers. The mean (SD) values were 7.14 (2.26) and 6.63 (1.7) for the two groups, respectively (p-value <0.001).
Conclusions: Associations between SB and different categories of OSA and GERD seem to exist. More research is needed to prove their direct/indirect effects on the pathophysiology of bruxism.
