Sleep bruxism reflects masticatory muscle behavior tied to health deterioration not mortality
Sleep bruxism reflects masticatory muscle behavior detrimental to health, but not tied to mortality suggests new study published in the Journal of Oral Rehabilitation
The association of sleep bruxism with mortality has not been studied previously.
This is the first study to examine the relationship between sleep bruxism and mortality. The association between sleep bruxism and increased risk of mortality did not hold when the regression model was adjusted for known risk factors for mortality. Sleep bruxism is not a disease that kills but rather reflects a masticatory muscle behavior detrimental to health.
Altogether 12 040 subjects from the nationwide Finnish twin cohort were included in the analyses. We examined whether self-reported sleep bruxism is associated with increased risk of mortality, and if so, whether the effect is independent of known common risk factors. The time span of the follow-up was 30 years.
Cox proportional hazards regression models (Hazard Ratios and their 95% Confidence Intervals) adjusted by age, sex and covariates were used to assess the effect of baseline bruxism status in 1990 on future mortality in 1990–2020.
