Abstract
Atendiendo a la localización de la reabsorción radicular, ésta puede ser clasificada en externa o interna. La reabsorción
interna es relativamente poco frecuente,
y su etiología y patogénesis no está todavía del todo clara. Este artículo muestra la complejidad de un incisivo central
superior con una reabsorción interna inflamatoria perforante. El diagnóstico definitivo lo hallamos a través del examen
tridimensional, que confirmó la extensión
y comunicación con la superficie externa
radicular.
Aunque como podremos ver a lo largo de
la exposición del caso clínico, la ayuda
del microscopio nos permitió abordar el
caso con mayor seguridad. En todo momento pudimos eliminar el tejido inflamatorio y preparar el conducto de manera
adecuada. La obturación en este tipo de
casos supone un reto para el endodoncista, siendo éste, mayor cuando se realiza
únicamente de manera ortógrada. Para la
obturación realizamos una técnica descrita en la literatura, sellando la zona apical
a la reabsorción con gutapercha adaptada mediante condensación vertical; la
zona reabsortiva con material biocerámico y, por último, la zona coronal con gutapercha inyectada.
Se realizó un 3D a los 26 meses para una
nueva evaluación de la zona reabsortiva,
y así evaluar el estado óseo alrededor de
la misma. La paciente se presenta totalmente asintomática sin signos clínicos y
con buena salud de los tejidos periapicales.
Based on the location of the root resorption, it can be classified as external or internal. Internal resorption is relatively rare, and its etiology and pathogenesis is not yet entirely clear. This article shows the complexity of a superior central incisor with a perforating inflammatory internal resorption. The definitive diagnosis is found through the three-dimensional examination, which confirmed the extension and communication with the external root surface. Although as we can see throughout the presentation of the clinical case, the help of the microscope allowed us to address the case with greater certainty. At all times we were able to remove the inflammatory tissue and prepare the duct properly. The obturation in this type of cases supposes a challenge for the endodontist, being this one, greater when it is done only in an ortograde way. For the filling, we performed a technique described in the literature, filling the apical area with resorption with gutta-percha adapted by vertical condensation; the resorptive zone with bioceramic material and finally the coronal zone with injected gutta-percha. A 3D was performed at 26 months for a new evaluation of the resorptive zone, and thus evaluate the bone state around it. The patient presents totally asymptomatic without clinical signs and with good health of the periapical tissues.
