Abstract

Developmental dental anomalies are a common finding in adolescent populations. The objective of this study was to utilize panoramic radiographs to determine the prevalence of dental anomalies and developmental disturbances in a heterogenous adolescent orthodontic patient population seeking care at a North American orthodontic residency program. A total of 1042 panoramic radiographs of 457 male and 585 female orthodontic patients aged 10 to 18 years were evaluated. Developmental and eruption anomalies were recorded and categorized, and chi-square and Fisher exact tests were used for statistical analysis. The evaluation revealed that 40.88% of patients had at least 1 anomalous finding. The most common finding overall was agenesis (12.00%), followed by deviations in eruption path (9.12%), delayed eruption (7.39%), and impaction (7.29%). There was no difference in the prevalence of having any anomalous finding or the prevalence of any specific category of anomalies based on the sex or Angle classification of the patients. Comparison of developmental dental anomalies in 3 age groups (10 to 12, 13 to 15, or 16 to 18 years) revealed no statistically significant difference in the overall prevalence of anomalous findings. Statistically significant differences for some specific categories of anomalies were explainable by correlating dental development with chronologic age, such as a greater frequency of blocked out teeth and eruption path deviation among patients aged 10 to 12 years. Black patients were found to have a significantly greater prevalence of impac-tions (P = 0.030), and Asian patients had a significantly greater prevalence of anomalies categorized as "other pathology," which could not be definitively diagnosed by panoramic radiograph alone (P = 0.007).
