Abstract
The study assessed the prevalence of diurnal bruxism among information technology (IT) professionals and explored plausible predictors associated with the parafunctional habit. A cross-sectional study was designed and IT professionals were invited to participate. The inclusion criteria composed of participants in service for at least one year, having natural dentition, no history of cervical or facial injury and not undergoing orthodontic therapy. The participants (N = 147) were interviewed by a trained interviewer to record information. A pre-tested questionnaire that included questions related to work, stress symptoms and diurnal bruxism was completed by each participant. The prevalence of self-reported diurnal bruxism was 59%. Bivariate analyses revealed that work (P < 0.05) and work experience (P < 0.05) were significantly associated with self-reported diurnal bruxism. In the binary logistic regression analysis stress (Odds Ratio [OR] = 5.9, 95% Confidence Interval [CI] 2.6–13.3) was identified to be a strong predictor of diurnal bruxism. Professionals with 11 or more years of experience were less likely to report diurnal bruxism (OR = 0.04, 95% CI 0.00–0.43) than those with 1 to 5 years of work experience. The study revealed that stress and less work experience were associated with diurnal bruxism among IT professionals in Bangalore city.
Highlights
Masticatory muscle activities can be normal or abnormal in nature and are categorized as functional or parafunctional [1]
Out of 164 who volunteered to participate in the study 17 were excluded since they had work experience less than 1 yr (n = 9), partial denture (n = 5), undergoing orthodontic therapy (n = 2), and history of injury (n = 1)
The pilot study found that majority of the participating information technology (IT) professionals reported to have diurnal bruxism
Summary
Masticatory muscle activities can be normal or abnormal in nature and are categorized as functional (e.g., chewing swallowing, and speaking) or parafunctional (e.g., tooth clenching, grinding, and various oral habits) [1]. Bruxism is one such parafunctional activity (PA) commonly seen in humans. It is defined as a diurnal or nocturnal PA that includes clenching, bracing, gnashing, and grinding of teeth [2, 3].
