Abstract Numerous studies in the past have been conducted to determine the prevalence of malocclusion in different populations. These show extreme variations and it is only right to determine the prevalence in a referred population. Class III malocclusion even though it is the least common, treatment planning and treatment is quite difficult, thus characteristics of class III malocclusion need to be studied in detail.The aim of the study is to evaluate the prevalence of crowding among patients with class III malocclusion visiting Saveetha dental college and hospitals. A retrospective study was done using case sheets of patients visiting the university hospital from June 2019- February 2020. About 100 case sheets of patients visiting the department of orthodontics containing information on malocclusion type and crowding was retrieved and analysed using SPSS 20.0. The study included 100 patients out of which 74% were males and 26% were females.Crowding was observed in 51% of the patients with class III malocclusion. Out of which 62.75% of the patients were reported to have minimal crowding ,31.37% had moderate crowding and 5.88% had severe crowding of the mandibular incisors. There was no statistically significant association between age, gender, and severity of crowding as determined by pearson's chi-square tests.Within the limits of the study, it can be concluded that mild mandibular crowding was the most common finding in class III malocclusion patients.
