Tomografia computadorizada de feixe cônico na avaliação da reabsorção radicular externa

Abstract

The external root resorption (ERR) is a consequence triggered and maintanined by biological and multifactorial mechanisms and, despite being widely debated in the literature, is still not well understood. Sometimes diagnosis of these lesions is difficult due to the absence of characteristics clinical signs or symptoms. As radiographic images are two-dimensional, it could overlap of anatomical structures. Theses overlaps, in certain situations, limit the observation of images suggesting external root resorption as they show themselves very small and in areas in wish visualization is difficult. The development of TC scans small appliances along with computer technology improved the diagnosis of a resorption external to the root by images acquired by Cone Beam (FC). Three dimensional images provided by these devices made early detection of lesions easier, giving precise location and measurements giving the professional chances to develop a more efficient and appropriate plan to treat the lesions, thus directly influencing tissue repair and a more favorable prognosis for dental maintenance.
