Association of sleep bruxism with oral health-related quality of life and sleep quality.Clin Oral Investig 2019; 23(1):245-251CO
To compare the oral health-related quality of life (OHRQoL) and sleep quality of subjects with and without sleep bruxism (SB).
MATERIALS AND METHODS
Participants of both genders were assigned as bruxers (n = 30, age 21-45 years) and non-bruxers (n = 30, age 24-40 years). SB was clinically diagnosed and confirmed with an electromyography/electrocardiograph portable device (Bruxoff). The OHRQoL was assessed using the Oral Health Impact Profile (OHIP-14). The sleep quality was determined using the Pittsburg Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS) questionnaires. OHIP-14, PSQI, and ESS data were analyzed by one-way ANOVA, considering a significance level of 5%.
Bruxers had worse OHRQoL (mean = 16.43) than controls (mean = 4.1), with an effect size (ES) of 1.58. Moreover, SB volunteers showed the highest PSQI scores (mean = 7.07; ES = 0.82) and excessive daytime sleepiness (mean = 10.33; ES = 0.65), compared to non-bruxers (means = 4.7 and 7.8, respectively).
SB may be associated with a negative impact on OHRQoL and sleep quality.
Determining that SB may have a marked role in OHRQoL and sleep quality is important for dental professionals establish proper multifactorial management, and understand patient-related psychosocial aspects.
