Preeruptive intracoronary resorption: Radiographic finding. Case Report.

Abstract

Abstract: Preeruptive intracoronary resorption is a radiographic finding consisting of the presence of a radiolucent area located in the coronal dentin, close to the amelodentine junction in the germ of a tooth. The literature reports a variable frequency between 0.85% and 27.3%. Its etiology is unknown and a relationship with sex has not been demonstrated. They are considered as caries lesions after tooth eruption. Objective: To describe the radiographic findings of a case of preeruptive intracoronary resorption. Case report: Male patient, 5 years old, in first stage mixed dentition, who attended dental control and evaluation for interceptive orthodontic appliance making. Panoramic radiography was requested to evaluate dental evolution and plan treatment. The x-ray identified a radiolucent area in the intracoronary area of tooth 4.7, which is in intraosseous evolution stage Nolla 4. After analyzing the clinical case with the interdisciplinary teaching team, the diagnosis of preeruptive intracoronary resorption was concluded, and the need to establish a radiological follow-up protocol until the eruption of the tooth was suggested. Conclusion: It is important to request a panoramic radiograph during the dental check-up in order to detect preeruptive alterations and to establish an adequate follow-up and monitoring by the pediatric dentist.
