Uso de laTomografia Volumétrica de Haz Cónico en el retratamiento endodóntico

Abstract

The use of Cone Beam Computed Tomography (CBCT) is changing the diagnostic evaluation of endodontically compromised teeth in our daily practice. Two-dimensional (2-D), whether they are conventional film or digital images, cannot accurately offer the full three-dimensional (3-D) representafion of the teeth and supporting structures. The CBCT allows the clinician to view the tooth and pulpal structures in thin slices in all three anatomical planes: axial, sagital, and coronal. The use of this complementary exploration radiographic tool, gives inyaluable information of the pulp system of teeth with persistent apical periodontitis undergoing root canal retreatment. The article presents a clinical example of the value of using Cone Beam Computed Tomography (CBCT) for pulp canal interpretation prior to endodontic retreatment and shows the final treatment.
