Prevalence of pre-eruptive intracoronal resorptions in children and evaluation of associated factors: A retrospective study

Purpose: This study aimed to determine the prevalence of pre-eruptive intracoronal resorption (PEIR) in children aged 4–14, evaluate the most commonly affected teeth, and identify possible etiological factors.
Methods: In this retrospective study, panoramic radiographs of pediatric patients who applied to the Department of Pediatric Dentistry at Bolu Abant İzzet Baysal University were examined between 2020 and 2023. Radiographs with sufficient diagnostic image quality and at least one unerupted permanent tooth were included in the study. The presence of PEIR, the lesion’s localization, depth, the number of affected teeth, and possible etiological factors were examined.
Results: 2229 panoramic radiographs were examined. 1893 of them were found to meet the study criteria. PEIR was detected in 64 patients, and the number of teeth with PEIR was 88. PEIR was seen at a rate of 3.4% on an individual basis and 0.34% on a tooth basis. It was most frequently detected in mandibular second molars and at Grade 1 level. Lesions were more commonly located in the mandible and on the right side; in most individuals, only one tooth was affected. No significant predisposing factor was found in 90.9% of the cases.
Conclusion: PEIR is a lesion that should be carefully monitored in the early age group and progresses asymptomatically most of the time. Early diagnosis and regular radiographic follow-up are essential to prevent pulpal complications.
