Malocclusion is the abnormal alignment of teeth within the dental arches. The prevalence of malocclusion varies among populations based on the race, ethnicity, age and gender. Class II malocclusion is one of the most common malocclusion in various populations. Appraisal of distribution of malocclusion in children can facilitate early efforts to prevent developing malocclusion and its consequences and also reduce the complexity of orthodontic treatment. The present aim of this study is evaluate the prevalence of class II malocclusion in mixed dentition. A retrospective study was carried out in patients who visited Saveetha Dental College with mixed dentition. The data were collected from patients records analysed from the data of 86000 patients between June 2019-March 2020. The data recorded were entered and subjected to statistical analysis using SPSS software. Chi square test was done between age and gender among class II occlusion patients. Out of 4420 patients, 3484 patients had class II malocclusion. Among 3484 patients, 1942 (55.7%) were males and 1542 (44.3%) were females. Association between age and gender of class II patients was found to be statistically significant [p<0.05]. The present study concludes that the prevalence of Class II occlusion in mixed dentition was found to be 78.9%. 10 year old patients had higher prevalence rates of class II occlusion among mixed dentition and least prevalence of class II malocclusion was seen in the 6 year old patients.
