Unusual case of internal resorption in cervical region of maxillary left lateral incisor

We treated an unusual case of internal resorption of the maxillary left lateral incisor seen in a 15-year-old female. The patient was referred to our clinic complaining of repeated cold pain and spontaneous pain in the maxillary left lateral incisor region. An intraoral examination revealed that the tooth was a microdont with a large tubercle, with a pink spot observed in the mesiopalatal area, while radiograph revealed an unusual radiolucent lesion in the cervical area of the affected tooth. Our diagnosis was internal resorption and the affected tooth symptoms ceased after a pulpectomy was performed. Over the next 3 years, periodical examinations performed at 3-month intervals did not reveal further resorption.
