title: Bruxism and quality of life in schoolchildren aged 11 to 14.
abstract: The purpose of this study is to assess quality of life in relation to oral health in schoolchildren with sleep bruxism. It is a transversal observational study of 594 schoolchildren (aged 11-14) of the municipality of Teresina, in the Brazilian State of Piauí. Quality of life was assessed through the Brazilian version of the CPQ11-14 questionnaire, in the short form (ISF:16).The presence of sleep bruxism was assessed from reports by the people legally responsible for the children. The results were analyzed by: calculation of an Odds Ratio (OR) estimate of chances; descriptive analysis; a Pearson Chi-squared test; a Likelihood Ratio test; and multiple logistic regression. A statistically significant association was found between sleep bruxism and the total score on the CPQ11-14 (p < 0.001), and with the scores in two domains: functional limitation (p = 0.033);and social wellbeing (p= 0.020).No association was found between quality of life and the variables gender or age. The final regression model showed that the presence of sleep bruxism increases the chance of having a greater effect on quality of life (ORadj=1.82 (1.54 - 2.10), IC = 95%).It is concluded that sleep bruxism had a negative impact on the quality of life of the schoolchildren, principally in the two domains functional limitations and changes in social wellbeing.
