Paget's disease of the mandible — a review and report of a case

Paget's disease is a chronic progressive disease of bone of unknown etiology. Jaw involvement is seen in approximately 17% of cases, and usually it is the maxilla that is involved. This is a report of a case of Paget's disease involving the mandible. An apparently uncommon observation was severe resorption of the roots of the 2nd molar tooth. Clinically the tooth appeared ankylosed. After surgical removal, the tooth was fixed, demineralized and paraffin sections were made. The microscopic evaluation revealed that the root structures had been replaced by osseous tissue by a mechanism of replacement resorption.
