Tracing teeth and time: A mixed-method study on lifecourse perspective of oral health in geriatric populations

Objectives: This study aimed to explore oral health experiences across different life stages among geriatric individuals and to develop a validated questionnaire based on these qualitative insights. Methods: A pilot qualitative study was conducted using in-depth interviews among elderly participants aged 60 years and above. Interviews were audio-recorded, transcribed verbatim, and analyzed thematically using HyperRESEARCH software. Based on emergent themes, a structured questionnaire was developed and administered among geriatric residents of old age homes in Delhi. Results: Five major themes across four life stages were identified, highlighting transitions from traditional oral health practices to reactive dental care and prosthetic dependence. Despite higher socioeconomic background in some participants, perceived cost and undervaluation of oral health emerged as major barriers to care utilization. Conclusions: A lifecourse approach provides meaningful insight into geriatric oral health trajectories and can guide development of age-sensitive oral health policies and service models.
