Background: Oral diseases are often called a neglected epidemic, because they affect virtually the entire population and often not identified as a priority. The aim of this study was to estimate the oral health status and disease burden among adults aged between 18-70 years and to assess the oral health related quality of life (OHRQoL) of these subjects using oral health impact profile (OHIP-14) Methods: A descriptive cross-sectional survey with convenience sampling was executed to study the native Kerala population in the selected locations. A total of 1714 people participated in the study out of which 1552 were taken for data analysis. Variables collected as per the WHO proforma for adults. The OHRQoL of these subjects were recorded using the OHIP 14 questionnaire, Malayalam version. Bivariate analysis of OHIP scores was done and multi variate analysis using binary logistic regression for determining factors responsible for poor OHRQoL. Results: The model showed that presence of caries experience was the most important factor associated with a poor OHRQoL. Presence of oral mucosal lesions was not significantly associated with development of poor OHRQoL. The goodness of fit for the model verified using Hosmer and Lemeshow Test (p <0.05) indicated that the goodness of fit of the model was acceptable with a Nagelkerke R Square value of 0.127. Conclusion: We recommend that a population based study be carried out to exactly assess the oral health burden in the state and an effective oral health policy be formulated accordingly.
