Abstract: The pre-eruptive intracoronal resorption refers to the abnormal defect of tooth tissue before eruption. The etiology of the disease is not clear, and there are no obvious clinical symptoms. The X-ray shows abnormal and well-defined local transmission images. The prevalence of the disease is 2.2%-4.1%, and most of the cases are accidentally found during imaging examinations. This paper reports a case of the pre-eruptive intracoronal resorption in a permanent maxillary canine, aiming to enrich the case database of this disease and provide reference for clinical diagnosis and treatment.

Key words: pre-eruptive intracoronal resorption, permanent canine teeth, pediatric dentistry
