- Anomalies were more frequent in the mixed dentition stage and in the maxilla.

## Abstract

The prevalence of developmental dental anomalies among 5,000 school children aged 5-15 years in Ghaziabad, Uttar Pradesh is of
interest. We examined their association with age, sex, dentition stage, jaw location, and socioeconomic status. Data were collected from
school-based screening camps and pediatric outpatients at Santosh Dental College. Enamel hypoplasia was the most common anomaly,
followed by supernumerary teeth and talon cusp, while micro-dontia, fusion, and hypodontia were less frequent. Most anomalies showed no
gender bias, except for enamel hypoplasia and talon cusp. Higher prevalence was observed in children from lower socioeconomic groups, in
the mixed dentition stage, and predominantly in the maxilla.
