Abstract

This cross-sectional study uses radiographs of 908 orthodontic patients with goals: describe some characteristics of the distribution of impacted permanent teeth (except third molars) in these patients. Results: The percentage of impacted permanent teeth (except third molars) in orthodontic patients is 8,59%, the male is higher than female (p<0,05). The youngest patients who are diagnosed having impacted permanent teeth are 6 years old. Impacted teeth are observed more in the upper jaw. The most commonly impacted permanent teeth are impacted upper canines (4,52%) and impacted upper lateral incisors (3,52%). Most of the cases have one impacted tooth. Conclusion: The result of this study brings out a comprehensive view about the distribution of impacted permanent teeth (except third molars) in both jaws, age suggestion, the potential of tooth and segment, provides the foundation for the clinical enhancement of tracking and interventions.
