Case of the Week: Invasive cervical resorption

This week I am showing a case of a specific kind of external resorption (invasive cervical resorption).  This form of resorption occurs in the cervical region of a tooth.  There have been many different causes for this resorption suggested such as trauma, orthodontic movement, intracoronal bleaching, periodontal root scaling, etc.  While all of these have been suggested and some have been shown to be the cause it is idiopathic in many cases.  This case is on a mandibular central incisor – distal surface.  Note the radiolucent area over the cervical region where the resorption has occurred.

For more information and examples of invasive cervical resorption check out the research performed by Geoffrey S. Heithersay.
