Clinically, there are more than 12 types of root resorption. Although most dental resorption defects appear radiolucent at their advanced disease stages, they differ widely in etiology, histopathology, diagnosis, treatment and prognosis.
Most dental resorption problems are caused by dental treatments. Each dental specialty has its own encounter with the problem of resorption and found appropriate treatment and prevention methods. Unfortunately, such advanced specialty information is not taught to the dental student. A sampling of this information indicates that some of dental resorption pathologies lead to accelerated tooth loss and are best treated early and aggressively; some types of cervical resorption contraindicate endodontic treatment. How does the clinician distinguish? Dr. Abou-Rass sheds clinical light on the topic from the perspective of the critical complexities and necessity of accurate diagnosis.
External Endodontic Root Resorption occurs with every endodontic lesion, PA radiographs show 20% incidence. CBCT show 100%.
Unfortunately, without research since 1957, Bering and Lepp drawings of radiographic diagnosis of internal and external resorption have been dominating the dental school teaching on the subject of dental resorption
