Lithuanian dentists' knowledge, attitudes, and clinical practices regarding obstructive sleep apnea: A nationwide cross-sectional study

Objective: To investigate the knowledge, attitudes toward, and aspects of clinical practice regarding obstructive sleep apnea (OSA) among Lithuanian dentists. Methods: A cross-sectional study was carried out during the period from December 2016 to March 2017. A survey instrument was designed and pilot tested prior to full-scale administration. Self-administered questionnaires, including a cover letter, were distributed to 550 dentists during continuing dental education programs. Results: A total of 353 participants (64.2%) completed and returned the questionnaire. Increased years of experience were significantly associated with lesser knowledge about OSA (p < 0.05). However, there were no significant differences between general practitioners and specialists (p = 0.243). Most respondents indicated strong positive attitudes regarding OSA. The majority did not have any clinical experience regarding the management of OSA patients. Discussion: Development of additional education and practical implementation strategies should be considered in order to overcome the examined barriers.
