Intracoronal Radiolucency in An Unerupted Premolar: A Rare Occurrence.

Pre-eruptive Intracoronal Resorption (PIR) is a lesion that mostly occurs within the dentin in the occlusal part of the crown, next to the dentin-enamel junction. Such lesions are usually detected accidentally, on routine intraoral radiographs. This case report highlights a case of PIR detected in the mandibular second premolar of a 10 year old boy. The radiographic finding, size, position and restoration of the defect have been mentioned.
