The aim of this study was to assess the prevalence of class I,II, III malocclusions in patients with bilateral cleft lip and palate. Cleft lip and palate are the most common congenital defects. Cleft lip and cleft palate can be divided into bilateral cleft lip and palate and unilateral cleft lip and palate. In patients with cleft lip and palate the prevalence of other dental anomalies is very common. Cleft lip and palate patients require a multidisciplinary treatment approach, to correct the cleft and other other associated defects. This study was done in a university based setting on the bilateral cleft lip and palate patients who reported to our hospital. The data was obtained by reviewing case sheets from June 2019 to March 2020 of Saveetha dental college and hospitals. The data was collected and tabulated in the excel sheets and exported to the SPSS software for statistical analysis. The prevalence of Class I was 52%, class III was 28% and Class II had 20% prevalence in bilateral cleft lip and palate patients. There was a difference between the incidence of different types of malocclusions among different genders, with more male predilection, however it was statistically insignificant. The prevalence of Class I malocclusion was more in our Bilateral cleft lip and palate population
