To assess the prevalence of patients requiring full mouth rehabilitation based on the turner and missirlian classification and assess the choice of the treatment plan. The study was done in the institutional hospital setting of Saveetha Dental College, Chennai. Patients requiring Full mouth rehabilitation were assessed, data was obtained from filtering the college database to obtain 65 patients. The patients were classified by the Turner and Missirlian classification based on their extent of rehabilitation required and the treatment protocol used for them was also assessed. The obtained data was tabulated using an Excel sheet and statistical analysis was performed using Pearson correlation. Prevalence of Category 1 Of turner and missirlian classification was among patients above 60 years (36.8%), For category 2 it's among patients between 50-60 years (33.3%), and category III (36.4%) showed similar results as class I in terms of prevalence. The treatment preferred was mostly tooth supported FMR, Category 1 (52.6%), Category II (47.2%), Category III (54.5%). Full mouth rehabilitation involves extensive rehabilitation of oral structures requiring a meticulous interdisciplinary approach. The study shows the increased requirement of full mouth rehabilitation among elderly patients. Research analysing the prevalence of patients in need for such rehabilitation could give us a ground report on the oral health status of a population, and could prove to be valuable literature which could become the forerunner for research in analysing the treatment protocols.
