Impact of malocclusion and oral habits on oral health-related quality of life and sleep disturbance in young adults : Across-sectional study.

Abstract

The aim of this study was to investigate the impact of malocclusion and oral habits on oral health-related quality of life and sleep disturbance in young adults. Across-sectional study was conducted with asample of 213 young adults aged 18-30years. Dental occlusion data were assessed through clinical examination. Aquestionnaire was used to collect data on oral habits. Outcomes were collected using the Oral Health Impact Profile (OHIP-14) and Mini Sleep Questionnaire. Anterior open bite (adjusted odds ratio [OR] = 2.41, 95% confidence interval [CI] = 1.02-5.67, p = 0.044), swallowing disorders (adjusted OR = 2.39, 95% CI = 1.13-5.05, p = 0.022), and sleeping on hands were associated with anegative impact on oral health-related quality of life. Females (adjusted OR = 2.61, 95% CI = 1.10-6.17, p = 0.029), teeth grinding (adjusted OR = 2.78, 95% CI = 1.08-7.14, p = 0.034), biting lips or cheeks (adjusted OR = 4.28, 95% CI = 1.49-12.29, p = 0.007), and self-perception of need for orthodontic treatment (adjusted OR = 7.88, 95% CI = 2.12-29.30, p = 0.002) were associated as arisk for sleep disturbances. The findings suggest that oral habits and some types of malocclusions can impact oral health-related quality of life. In addition, sleep disturbances were associated with agreater need for orthodontic treatment and ahabit of grinding teeth in young adults.
