468 - Pre-Eruptive Intracoronal Resorption in a 17 Year Old Male

Introduction: Pre-eruptive intracoronal resorption (PEIR) is a rare dental abnormality characterized by a loss of dentin and enamel prior to tooth eruption. This condition presents difficulties for the affected tooth as it weakens its structural integrity. PEIRs are often diagnosed early through panoramic radiographic assessment, in which a provider will identify a well-defined circular radiolucency within the dentinal aspect of a tooth just below or within the most inner aspect of the enamel.

Case Report: This 17-year-old male patient with Joubert syndrome, developmental and cognitive delay, obstructive sleep apnea, and a G-tube presented to CHLA dental clinic. Upon examination, it was noted that the patient had two supernumerary teeth fully erupted in the palate. The treatment plan involved comprehensive dental treatment under general anesthesia, primarily focusing on the extraction of the supernumerary teeth. During the examination under general anesthesia, it was noted that tooth #20 had a radiographically diagnostic PEIR. Further preparation revealed the presence of softened dentin, which felt as soft as pulpal tissue, and irregularly shaped defects within the tooth structure. Early detection and restoration is the ideal treatment for PEIR management, offering a promising solution for affected teeth.
