PurposeThe purpose of this study is to analyze the clinical records of all patients evaluated for supernumerary teeth at the University of Illinois, Department of Oral and Maxillofacial Surgery postgraduate clinic from January 1, 2010 to October 31, 2015 in order to determine the demographics of impacted supernumerary teeth among different ethnicities within the city of Chicago, Illinois.Patients and MethodsA retrospective case series was completed on subjects eligible for inclusion in the study who had a diagnosis of at least one full bony impacted supernumerary tooth (D7240). Other variables evaluated included date of surgical intervention, age at time of treatment, gender, ethnicity, location and number of supernumerary teeth present, and family history of supernumerary teeth.ResultsThere were 459 male and 308 female patients, with a 1.5:1 male:female ratio. Patient ages ranged from 4 to 51 years (avg. 13.1) at the time of surgery. 74.7% (573) of the patients were of Hispanic descent. Supernumerary teeth were found most frequently in the maxilla (69.9%), specifically in the central incisor region (526 teeth, 51.2%). In the responding patient sample (258 patients), 53 patients (20.5%) reported a family history of supernumerary dentition. Of these 53 patients that reported a family history of supernumerary dentition, 37 (69.8%) were of Hispanic descent. The majority of these Hispanic patients (83.8%) originated from Mexico.ConclusionsThe incidence of supernumerary teeth is higher among male patients (M:F ratio of 1.5:1), and these teeth are most frequently found in the maxilla (69.9%), specifically the central incisor region (51.2%). A large percentage of patients (20.5%) also have first-degree relatives with a supernumerary dentition, and this fact may warrant further investigation into the possible genetics responsible for the formation of supernumerary teeth.
