Background: This study was aimed to investigate the prevalence of primary malocclusion among school children under 5 years of age in Chennai, Tamil Nadu.

Materials and methods: A total of 814 school children under 5 years were selected from 5 government and 5 private schools in Chennai city, Tamil Nadu, India, and their occlusion was recorded based on the terminal planes. Data were analyzed using SPSS version 16 software. Frequency distribution and Chi-square test were carried out.

Results: The most common occlusion seen in the present study was flush terminal plane (54.05%). Of them, 43.73% had mesial step and 2.08% had distal step. There was no significant difference between males and females.

Conclusion: The signs of future malocclusion are found to be high. Hence, early preventive and interceptive measures are necessary to reduce the prevalence of future developing malocclusion and further adverse effects.
