Abstract :Purpose: The purpose of this study was to investigate the impacted supernumerary teeth which were initially detected on panoramic radiographs by using cone beam computed tomography insert ignore into journalissuearticles values(CBCT);. Materials and Methods: In this retrospective study, supernumerary teeth diagnosed on panoramic radiographs taken from patients who had admitted for routine dental treatment were evaluated using CBCT. Patients’ age, gender, systemic conditions as well as number of supernumerary teeth, unilateral-bilateral presence, anatomical localization insert ignore into journalissuearticles values(maxilla, mandible, anterior-premolar-molar, mesiodens-lateral-canine, parapremolar-paramolar-distomolar); shape insert ignore into journalissuearticles values(rudimentary, supplemental, tuberculate, odontoma);, position insert ignore into journalissuearticles values(palatal-lingual-buccal-labial-central);, shortest distance between the tooth and adjacent cortical plate, complications and treatment were assessed. Results: A total of 47 impacted supernumerary teeth in 34 patients were investigated in this study. Of these, 33 insert ignore into journalissuearticles values(70.2%); were unilateral and 14 insert ignore into journalissuearticles values(29.8%); were bilateral. Only 1 supernumerary tooth was found in 27 patients insert ignore into journalissuearticles values(79.4%); whereas 7 patients insert ignore into journalissuearticles values(20.6%); had 2 or more supernumerary teeth. Most of the teeth located in the anterior region insert ignore into journalissuearticles values(74.4%); of the jaws and maxilla insert ignore into journalissuearticles values(74.4%);. Twenty teeth insert ignore into journalissuearticles values(42.5%); were mesiodens, 11 insert ignore into journalissuearticles values(23.4%); were lateral or canine, 14 insert ignore into journalissuearticles values(29.7%); were parapremolar and 2insert ignore into journalissuearticles values(4.4%); were distomolar. Twenty-seven teeth insert ignore into journalissuearticles values(57.4%); were rudimentary, 15 insert ignore into journalissuearticles values(31.9%); supplemental and 5 insert ignore into journalissuearticles values(10.7%); odontoma in shape. The shortest distance between the supernumerary tooth and adjacent cortical plate varied between 0 to 2.5 mm with a mean of 0.66 mm. The most common clinical complaint was the non-eruption of permanent teeth insert ignore into journalissuearticles values(42.5%);. All supernumerary teeth were removed under local anesthesia. Orthodontic traction was performed for those impacted permanent teeth if necessary. Conclusion: Impacted supernumerary teeth are usually in close proximity to cortical bone. Although this may facilitate surgical access, there is a risk of damaging surrounding anatomical structures. Therefore, CBCT evaluation of impacted supernumerary teeth for accurate planning is recommended.
