Psychosocial Determinants of Oral Health Related to COVID-19 Infection in Myanmar Older Adults.

This study aims to investigate and compare the psychosocial and oral health factors among Myanmar older adults with and without a history of COVID-19 infection and assess the association between psychological factors and oral health outcomes among those with a history of COVID-19 infection. A cross-sectional study was conducted among 203 participants in Yangon from 2023 to 2024 using face-to-face interviews and clinical oral examinations. Participants with a history of COVID-19 infection experienced greater psychological distress and poorer oral health outcomes than those without such a history. In those who contracted COVID-19, depression positively associated with decayed teeth; decayed, missing, and filled permanent teeth (DMFT); and oral health impact profile-14 (OHIP-14), whereas negatively associated with present teeth. Anxiety positively related to decayed teeth, DMFT, and periodontal pockets. Stress negatively associated with decayed teeth, but positively with OHIP-14. Implementing oral health promotion programs and providing mental support for this vulnerable population are essential to improve their oral health and well-being.
