ABSTRACT

Background : Medication is the most cause of salivary function impairment in elderly, leading to hyposalivation either with or without xerostomia. There are many consequences of hyposalivation that influence oral health-related quality of life (OHRQoL) by decreasing oral health status. Aim : To investigate whether xerostomia and hyposalivation were risk factors for poor oral health status in Indonesian elderly. Methods : Oral health status of 76 elders in Yogyakarta, Indonesia were determined by conducting intraoral examination comprised of oral hygiene (OH), DMFT index, periodontal tissue status and number of natural occluding pairs. Xerostomia was determined by self-reported responses on the Xerostomia Inventory (XI) and hyposalivation (volume of saliva <0.1 ml/min) was identified by measuring whole unstimulated saliva flow using spitting method. Estimation of Relative Risk (RR) was carried out to identify the risk factor. Results : Periodontal pocket, high DMFT index, poor OH, ≤ 5 natural occluding pairs, xerostomia and hyposalivation were experienced by 12, 38, 2, 42, 37 and 8 of 76 participants, respectively. Relative Risks (RRs) of xerostomia for the occurrence of periodontal pocket, high DMFT index, poor OH, ≤ 5 natural occluding pairs were 0.69 (CI 0.25-1.95), 0.87 (CI 0.58-1.30), 0.97 (CI 0.06-14.82), 1.17 (CI 0.82-1.67), respectively. Whereas, RRs of hyposalivation for the occurrence of those (except for poor OH) were 2.67 (CI 0.94-7.58), 1.50 (CI 1.03-2.19), 1.33 (CI 0.93-1.91), respectively. It appears that Indonesian elderly with hyposalivation has 2.67 fold and 1.50 fold of risk having periodontal pocket and high DMFT, respectively compared to the elderly without hyposalivation. Relevance : By identifying that hyposalivation is the main risk factor for poor oral health status in elderly, this finding can be used as consideration by oral health professional to plan the most suitable management for elderly with hyposalivation, in turn, it can improve the OHRQoL of elderly.
