Abstract: Introduction Resorption mechanisms triggered in teeth can lead to lesions, especially in instances of impacted dentition. Evidence of these lesions can be detected via radiographic imaging and are often classified as pre-eruptive intra-coronal resorption (PIR). These resorptive lesions do not typically present with symptoms of pain or discomfort, however, it is hypothesized that these cases may progress and affect more than ⅔ of the dental width. Methods This case series investigated 15 panoramic radiographs of patients who presented with abnormal radiolucent intracoronal zones or PIR lesions within unerupted teeth. Once the affected teeth were confirmed, an observer with 20 years of experience in oral and maxillofacial radiology scored the PIR lesion according to an established classification system. Results Twenty cases of PIR lesions were observed amongst the 15 subjects investigated with 75% of cases being located in the maxillary teeth. Lesions mostly presented in molars and premolars (70% of cases). Resorption was detected in the dentin or near the pulp of the tooth in 95% of cases with the most common scoring having resulted in lesions affecting more than ⅔ of the dentine, the enamel and between ⅓-⅔ of dentine as well as dentine and less than ⅓ of the root. Conclusion Further understanding of the progression and diagnosis of this defect can assist experts in conceptualizing its aetiology and advice on the most effective treatment plan for patients.
