Prevalence of Developmental Dental Anomalies of Number and Size in Indian Population According to Age and Gender

INTRODUCTION: Dental anomalies arise due to genetic and environmental factors in the morphodifferentiation stage of odontogenesis lead to alteration in the number and size of the tooth as well as the root.(1–3) The knowledge of their prevalence and the extent of involvement can provide valuable information for phylogenic and genetic studies and also help in the understanding of differences among the population and between various population groups.(4) We aim to identify the prevalence and distribution of such anomalies according to age and gender. The acquired details of cases will further help the dental clinicians to understand their etiology which can further facilitate their diagnosis and effective management. Also, timely intervention can be achieved. MATERIALS AND METHODS: Retrospective study of 4,000 subjects (equal proportion of males and female) of age range from 10 to 40 years were studied. Their radiographs, dental casts, and clinical findings were evaluated for number and size developmental dental anomaly. RESULTS: Incidence of overall 331 cases (8.27%) of number and size developmental dental anomalies were recorded with 173 (8.6%) males and 158 (7.9%) females. Hypodontia was the most frequently found dental anomaly in both males (4.9%) and females (4.4%) followed by hyperdontia and supernumerary roots. Microdontia was the most frequently found size anomaly in both males (1.6%) and females (1.9%). CONCLUSION: Hypodontia (4.7%) is the most frequently found numeral anomaly in both males and females. Intergroup study shows a significant statistical difference in cases of hypodontia in the 10–25 years of age-group (6.2%) with a p value ≤ 0.00001.
