Abstract
OBJECTIVES: This retrospective study aimed to investigate the prevalence of pre-eruptive intracoronal resorption (PIR) in unerupted permanent teeth in a Turkish population using cone beam computed tomography (CBCT). METHOD: A total of 1,317 CBCT images were screened. In all the images, the following were recorded: the number of unerupted teeth, number of teeth with intracoronal resorption, affected tooth type and number, and location of radiolucent defects. Demographic data were also obtained. RESULTS: The prevalence of intracoronal resorption in the study group was 15.1%, with a prevalence in teeth of 3.5%. The prevalence of intracoronal resorption using CBCT was much higher than that recorded previously using panoramic or bitewing radiographs intracoronal resorption was more common in males (57%) than females (43%). Twenty-three cases were located in the maxilla (48%), and 25 were located in the mandible (52%). The mandibular third molar was the most affected tooth type, followed by maxillary third molars and supernumerary teeth. CONCLUSION: CBCT can be useful for diagnosing PIR defects because it provides an accurate representation of internal dental anatomy. SCANNING 38:442-447, 2016.
