Classification of cases of pre-eruptive intra-coronal resorption

Resorption mechanisms triggered in teeth can lead to lesions, especially in impacted dentition. Evidence of these lesions can be detected via radiographic imaging and are often classified as pre-eruptive intra-coronal resorption (PIR). These external 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.
