Objectives: Aim of our study was to assess the occlusal traits of 3-5 year-old preschool children of India in primary dentition and the differences in traits with age. Methods: In present cross-sectional study primary dentition of 662 preschool children aged 3-5 years from preschool of Gandhinagar, India, using a stratified random sampling technique were examined. The study group was assessed for primary molar relationship, primary canine relationship, degree of over jet, degree of overbite and the presence of anterior crossbite, posterior crossbite and scissor bite. Results: The data that were collected was analysed using chi-square test. Results of our study showed that flush terminal plane was more common in age group of 3-4 years old children; mesial step was more common in age group of 4-5 years old children. Majority of children in both the age groups showed the presence of class I primary canine relationship. Both the age group showed the predominance of normal overjet and overbite. 0.2% of children showed presence of anterior crossbite, while no children showed the evidence of posterior crossbite or scissor bite. Conclusion: Mesial step molar relationship is most common molar relationship and it also increases with age. Deciduous molar relationship changes as the age increases. Lower prevalence of anterior open bite and anterior crossbite may be suggestive of lower prevalence of sucking habits. [Tithi A NJIRM 2016; 7(6):101-105]
