Abstract
Oral health-related quality of life (OHRQoL) using the oral impact on daily performance (OIDP) instrument among secondary school teachers in India is of interest. Hence, a cross-sectional survey of 1600 teachers aged 24-57 participated in interviews and oral health examinations. About 59.5% reported oral health issues affecting daily activities, with eating and sleeping most impacted. The OIDP showed high reliability (Cronbach's alpha = 0.87) and significant validity (p<0.05). Thus, OIDP is a reliable tool for evaluating OHRQoL in this population.
