Background: A study on prevalence, complications, and possible etiological factors of supernumerary teeth in 6–12-year-old schoolchildren of Rohtak, India. Aim: This study aimed to study the prevalence of supernumerary teeth in Rohtak district, Haryana, India and elucidate the possible etiological factors for their origin and the type of malocclusion caused by their presence. Materials and Methods: Two thousand and sixty school-going nonsyndromic children of 6–12-year age were examined for the presence of supernumerary teeth and referred to the Department of Pedodontics and Preventive Dentistry. Detailed history, clinical and radiographic examinations were done. Chi-squared test was used for statistical analysis. Results: Ninety-four supernumerary teeth were found in 81 children. All supernumerary teeth were found in maxilla. Most of these teeth were erupted, conical, and in the midline. Labial displacement of adjacent teeth was most commonly seen. Birth order of these children was mostly 2nd or 3rd, and majority of them belonged to the Jat community and were born at home by normal delivery. Conclusions: The present study emphasizes the necessity for early detection and appropriate management of supernumerary teeth. We suggest the development of further approaches including family studies to estimate the importance of genetic and possible environmental factors to attain a more precise knowledge of the etiology of hyperdontia.
