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 I 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 I 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 I occlusion patients. Out of 4420 patients, 3484 patients had
class I malocclusion. Among 3484 patients, 1942 (55.7%) were males and 1542 (44.3%) were females. Association
between age and gender of class I patients was found to be statistically significant [p<0.05]. The present study
concludes that the prevalence of Class I occlusion in mixed dentition was found to be 78.9%. 10 year old patients
had higher prevalence rates of class I occlusion among mixed dentition and least prevalence of class I
malocclusion was seen in the 6 year old patients.
