title: Multiple teeth showing invasive cervical resorption--an entity with little known histologic features.
abstract: Invasive cervical resorption is a relatively uncommon form of external root resorption, characterized by resorption of the cervical region of the root. There is progressive loss of cementum and dentine with replacement by fibrovascular tissue derived from the periodontal ligament, with deposition of cementum-like hard tissue. In most cases, a single tooth is involved. We report a case of invasive cervical resorption that resulted in loss of multiple teeth from two different quadrants. The case highlights the diagnostic difficulty that may arise in this uncommon lesion, the pathologic features of which may be mistaken for a fibro-osseous lesion or a low-grade sarcoma.
