The aim of the study is to assess the distribution of children based on the type of terminal plane in primary teeth among children of 3 to 5 years of age. A total of 200 children of 3-5 years were included in the study. The data of the children were obtained by analysing the patients records, Saveetha Dental College And Hospital. The molar relation of these children were recorded based on the terminal planes. Data obtained were tabulated in excel and imported to SPSS version 20 software. Frequency distribution and Chi-square tests were carried out to determine statistical significance. From the present study it was found that among the 200 children, 118 were male (59%)and 82 were female children (41%). 25.5% of children included in the study were 3 years,42.5% of children were 4 years, 32% of children were 5 years. Majority of children exhibited flush terminal molar relation by 44.5, 30.5% of children showed mesial step, and distal step was seen in 25% of children. The association between gender and type of malocclusion shows that flush terminal was more prevalent in male genders P value p<0.05. The association between age and gender of the children shows statistical significance P value p<0.05. Flush terminal plane is the most common primary molar relation found in the present study. Flush terminal was more prevalent in boys than girls which was statistically significant.
