Abstract
© 2019, Siriraj Medical Journal. Objective: To identify factors significantly associated with xerostomia in non-radiated patients. Methods: Patients who attended the outpatient otolaryngology clinic at Siriraj Hospital (Bangkok, Thailand) with complaints of dry mouth were invited to join this study. Collected data included age, gender, body mass index, smoking status, alcohol use, underlying disease, and previous medication and/or therapy. Irradiated patients were excluded. Participants were classified into either the diseased or xerostomia group by abnormal oral cavity examination and symptoms, or the no xerostomia group, which was defined as dry mouth symptoms with no presence of abnormal physical findings. Results: Two hundred and two participants with a history of dry mouth were consecutively enrolled. There were 86 patients with physical findings compatible with xerostomia, and 116 symptomatic patients without xerostomia. Multivariate analysis revealed age over 50 years (adjusted odds ratio [aOR]: 3.1, 95% confidence interval [CI]: 1.3-7.9; p=0.012), analgesic and muscle relaxant intake (aOR: 3.6, 95% CI: 1.3-9.7; p=0.012), psychotherapeutic medication (aOR: 7.8, 95% CI: 2.6-23.7; p < 0.001), and radioactive iodine therapy (aOR: 3.7, 95% CI: 1.2-11.8; p=0.015) to be independent predictors of xerostomia. Conclusion: Xerostomia is a condition that can adversely affect quality of life. The results of this study revealed older age (≥50 years), analgesics and muscle relaxants, psychotherapeutic medications, and radioactive iodine therapy to be significantly associated with xerostomia. A thorough understanding of the symptoms, diagnosis, relevant risk factors, and effective management is essential for improving outcomes among patients with xerostomia.
