Root Resorption in the Furcation Area: A Differential Diagnostic Consideration

Abstract

External root resorption can be found in the furcation area of mandibular teeth as a result of chronic inflammation. The radiolucent image is poorly delimited and departs from the well-delimited furcation involvement restricted to bone, which is a consequence of periodontitis. The careful interpretation of the clinical and radiographic signs can assist the clinician to differentiate the diagnosis of root resorption in the furcation area from furcation involvements that result from periodontitis.
