Background: Teeth may vary in number, size, and shape. Supernumerary teeth are a developmental anomaly of the number which may involve both primary and permanent dentitions.

Objectives: The objectives of the present study were to determine the prevalence of supernumerary teeth in the pediatric population of Manipur in North East India and to study the characteristics of supernumerary teeth.

Study Design: Observational study.

Materials and methods: The study was carried out in children from 3 to 14 years of age. Four thousand thirty-two children were examined over a period of 6 months who reported to the Department of Paediatric and Preventive Dentistry, Dental College, Manipur. Children with only supernumerary teeth were included whereas children with syndromes which are known to be predisposed to supernumerary teeth were excluded. The clinical and radiographical examination was done for diagnosis. Demographic details (age and sex) of children and characteristics of supernumerary teeth were noted.

Results: Out of 4032 children examined, supernumerary teeth were detected in 36 children (0.9%). Males were affected more than females with a male:female ratio of 2.3:1. Maximum supernumerary teeth were seen in mixed dentition (66.6%). About 86.1% of children had only one supernumerary tooth. 92.7% of supernumerary teeth were located in premaxilla. Conical shape was the most predominant (65.8%). 75.6% supernumerary teeth erupted while 24.3% were impacted. The majority were oriented straight (87.8%) with complete crown and root formation (80.4%).

Conclusion: The prevalence of supernumerary teeth was found to be 0.9% with the most common location being the premaxilla. Maximum supernumerary teeth were erupted and had straight orientation.
