Scleroderma is a rare connective tissue disease of unknown origin. It is characterized by increased collagen deposition leading to fibrosis and degeneration of the skin and sometimes of internal organs. There are two main groups of scleroderma: circumscribed scleroderma and systemic sclerosis. Circumscribed scleroderma is limited to the skin and systemic sclerosis has involvement of internal organs. The main oral manifestation of scleroderma is microstoma, which is a limiting factor in oral selfcare and professional oral health care. A case report is presented of the treatment of a 15-year-old female scleroderma patient with microstoma.
