Severe osteolysis of the mandibular angle and total condylolysis in progressive systemic sclerosis.

Progressive systemic sclerosis is an autoimmune disease characterized by gradual deposition of abnormal collagen which causes fibrous changes of the skin and visceral organs such as lung, heart, and kidney, which lead to serious complication. Microangiopathy and firm skin cause extrinsic pressure and obliteration of the vessels that lead to ischemia and destruction of the underlying bone. Salivary gland fibrosis causes xerostomia that increases risk of dental caries. Therefore, oral hygiene instruction (OHI) and preventive dentistry are recommended for these patients. We present a 36-year-old female that suffers from systemic sclerosis with total lysis of the mandibular condyle.
