This week I have a case of internal resorption that is small and still possible to treat without extraction. There is a linear radiolucent area over the root of the mandibular right central incisor (#25). Note that the radiolucent area is continuous with the root canal. Treatment to retain the tooth would include endodontic therapy to stop the resorption from continuing to enlarge. Click the image to enlarge.
