La resorción intracoronal preeruptiva (RIPE) es un defecto radiolúcido en la dentina coronal adyacente a la unión amelodentinaria de una pieza no erupcionada que solo puede ser diagnosticado mediante radiografías dentales. Este defecto, de ubicación anteroposterior y profundidad variables, afecta frecuentemente a las piezas posteriores, no está asociado al sexo y su etiología no ha sido determinada. La RIPE ha sido estudiada en distintas poblaciones pero aún no se han realizado estudios descriptivos en el Perú por lo que el objetivo del presente estudio fue determinar la frecuencia de RIPE en una muestra de 1897 radiografías panorámicas digitales de pacientes peruanos entre los 3 y 21 años de edad; la asociación estadística se determinó mediante la prueba del Chi cuadrado con un nivel de significancia (valor de p) menor de 0.05. La frecuencia de RIPE encontrada fue de 3.95...

Objective: To determine the frequency of Preeruptive Intracoronal Resorption (PIR) in a sample of digital panoramic radiographs of Peruvian patients between 3 to 21 years of age who attended an oral and maxillofacial radiology center between 2013 and 2021. Material and Methods: This observational study was descriptive, retrospective and cross-sectional. A sample of 1897 digital panoramic radiographs were evaluated to determine the frequency of PIR and its covariates of location, depth, and inclination of the affected teeth. The authors’ calibration was performed before the study. The intraoperator agreement was determined by calculating the Kappa coefficient (0.72, CI 0.67-0.76). The radiographs were evaluated by the study's principal author (IEP), and the data were collected in a form designed for the study. The statistical association was determined using the Chi-square test, with a ...

Preeruptive Intracoronal Resorption (PIR) manifests as a defect located in the dentin of a dental germ, adjacent to the amelodentinal junction in the crown. This defect, which varies in depth and anteroposterior location, can only be diagnosed through extraoral and intraoral x-rays, as well as dental tomography. The etiology of PIR remains undetermined, although histopathological studies suggest it could be a consequence of dental resorption. In this paper, panoramic x-rays and cone beam computed tomography (CBCT) scans of four patients with PIR are presented. The dental defects and enamel discontinuities adjacent to them are identified, highlighting the usefulness of CBCT in diagnosing and planning treatment for PIR cases.

Preeruptive intracoronal resorption (PIRR) is a radiographic phenomenon characterized by the presence of a radiolucent area situated in the coronal dentin near the amelodentine junction within the tooth's germ. Typically, this radiolucent area is singular and shallow, encompassing less than one-third of the chambered dentin. The reported frequency in the literature varies between 0.85% and 27.3%. No association with gender has been identified, and it predominantly affects posterior teeth. While its precise etiology remains undetermined, histological evidence suggests that it results from a sequelae of dentin resorption. RIPE Defects as Caries Lesions: Once the tooth erupts into the oral cavity, RIPE defects should be regarded in a manner similar to caries lesions. Despite the absence of established treatment schemes or clinical practice guidelines, reported treatments are contingent upon...
