Abstract
Aim: It has been speculated that the prevalence of xerostomia and hyposalivation might be higher among individuals attending oral cancer screening than among members of the general population. Therefore, this study investigated the prevalence of these conditions and their associated factors among individuals taking part in oral cancer screening and residing in the northeastern provinces of Thailand. Materials and Methods: This cross-sectional study recruited convenient individuals aged ≥40 years with at least one oral cancer risk factor. In total, 561 participants were included. Demographic characteristics and relevant oral cancer risk factors were recorded. A questionnaire comprising five items was used to assess xerostomia. Participants were then categorized into two groups based on the absence or presence of xerostomia. Subsequently, the stimulated salivary flow rate was assessed using the spitting technique to identify hyposalivation. Participants were then separated into two groups depending on the absence or presence of hyposalivation. Univariate and multivariate logistic regression analyses were then performed to identify factors associated with xerostomia or hyposalivation. Results: The mean age of participants was 65.62 ± 9.70 years, and approximately 60% of participants were post-menopausal women. The prevalence of xerostomia was 43.85%, and the prevalence of hyposalivation was 61.50%. It was revealed that age ≥65 years (odds ratio [OR] = 1.57, P = 0.02) and burning sensation in the mouth (OR = 5.36, P < 0.001) were strongly associated with xerostomia. Female participants were more likely to exhibit hyposalivation (OR = 2.38, P = 0.001). Oral cancer risk factors were not associated with xerostomia or hyposalivation. Conclusions: In this study, age ≥65 years and burning sensation were identified as risk factors for xerostomia, whereas female sex was a risk factor for hyposalivation. Dentists should be aware of both conditions. Various interventions to alleviate dry mouth symptoms might be useful for individuals with these risk factors.
