Knowledge and Attitude of Dentists Towards Obstructive Sleep Apnea

BACKGROUND: Obstructive sleep apnoea (OSA) is the most common sleep-related breathing disorder. Dentists should play an essential role in OSA screening, referral, and management. However, few studies have investigated dentists' knowledge and attitude towards OSA. OBJECTIVE: This cross-sectional survey aimed to assess the level of knowledge and attitude regarding OSA amongst dentists and evaluate whether the level of knowledge affects their attitude towards OSA. METHODS: Using the Google Forms platform, an online questionnaire was distributed via e-mail to all Ministry of Health dentists (N = 352). The questionnaire included 3 sections: demographics, knowledge, and attitude. Participant responses were stratified by professional title (general dentists, specialists, or consultants) and practice sector (primary health care centres or hospitals). Descriptive statistics, independent t tests, one-way analyses of variance, and Pearson's correlation were used to analyse the data. RESULTS: Of the 352 dentists, 191 responded to the questionnaire (54.55%). Although 80.6% of the respondents reported having previous OSA knowledge in the self-assessment question, 65.58% scored below 12 in the total knowledge scores, and 63.35% scored below 3 in the total attitude scores based on Bloom's cutoff. The mean total knowledge score was 9.86, while the mean total attitude score was 2.08. No significant differences between the mean total knowledge and attitude scores were found based on sex, professional title, or practice sector. A positive and statistically significant correlation was found between total knowledge and attitude scores (P value = .001). CONCLUSIONS: This study showed that dentists had a low OSA-related knowledge and a negative attitude towards OSA, and a positive association was seen between knowledge level and attitude. Dental practitioners with high knowledge scores tended to have a positive attitude towards OSA. These findings suggest that dentists in Jeddah require more education and clinical training in sleep medicine to maximise patient benefits and minimise adverse outcomes.
