Impact of Menopausal Duration on Salivary Flow Rate, Tooth Loss, and Oral Health-related Quality of Life in Indian Communities

Abstract

Background: Diminishing hormonal levels after menopause evoke physiological changes in a woman’s body. Their effects on the oral cavity are noteworthy, considering symptoms of dry mouth, altered taste perceptions, and tooth loss that may be attributed to reduced salivary flow and alveolar density changes. Aim: The purpose of this study was to assess changes in salivary flow rate, tooth loss, and oral health-related quality of life (OHRQoL) as menopausal duration increased. Materials and Methods: A total of 327 women fulfilling the eligibility criteria were chosen from two villages in the Mysuru district, Karnataka. They were categorized into three groups based on menopausal durations. Salivary flow rates, number of teeth lost, and OHRQoL after menopause were assessed and compared at different menopausal durations. Sociodemographic characteristics and oral hygiene practices were recorded to identify potential confounders. Results: Multivariate analysis demonstrated a significant association between menopausal duration and salivary flow rates (adjusted odds ratio = 2.269). However, no such associations were observed with tooth loss and OHRQoL. Conclusion: Menopausal duration significantly affects salivary flow rate. Its influence on tooth loss and OHRQoL is, however, less evident. Although strong associations cannot be established, the inevitability of the menopausal state advocates consideration of other major yet modifiable factors to improve oral health.
