The Frequency of Pre-Eruptive Intracoronal Resorption in Impacted Teeth with Complete Bone Retention: A Cone-Beam Computed Tomography Study: Cross-Sectional Study

Abstract

Objective: The aim of this study was to investigate the frequency of pre-eruptive intracoronal resorptions (PIR) and to determine whether PIR differs according to age and gender in impacted teeth with full bone retention. Material and Methods: A total of 2,434 permanent teeth from 2,365 (1,293 females, 1,072 males) patients between the ages of 18-89 were evaluated in the study. Semi-impacted teeth in eruption process, impacted teeth with jaw pathologies, primary teeth with full bone retention, mesiodens, and supernumerary impacted teeth were not included in the study. Descriptive statistics (mean, standard deviation) were calculated for all parameters in the study. The chisquare test was used to determine the relationships between categorical variables. p<0.05 was considered significant. Results: A total of 276 impacted teeth with bone retention were observed in 207 of 2,365 patients. PIR lesions (6 molars, 4 canines, 1 incisor, 1 premolar) were detected in 12 (4.3%) of the examined impacted teeth. Seven of them were in the maxilla and 5 were in the mandible. Five of the patients with PIR were male and 7 were female (p>0.05) and their mean age was 54.3 (28-75) years. Conclusion: The frequency of PIR in impacted teeth with complete bone retention was 4.3%, and it was most common in molar teeth. If the resorbed impacted tooth is likely to erupt, it should be followed up with restorative or endodontic treatment and tried to be kept in the mouth.
