RESUMEN
Systemic sclerosis (SSC) is a rare, systemic autoimmune disease of unknown etiology, which is characterized by fibrosis of visceral organs, skin and blood vessels. This disorder can be localized or systemic. It is more common in women with estimated prevalence is 250 cases in a million. Oral manifestations include xerostomia, periodontitis, decayed tooth etc. Radiographically generalized loss of bone with resorption of the mandibular angle and coronoid process can be evident in patients with scleroderma. Pressure of fibrous mucocutaneous tissues is thought to be the cause of the resorption. Decreased number of wrinkles due to sclerosis and distinct facial features because of the atrophy of ala nasi are among common clinical characteristics of this condition. The aim of this case series is to present two female patients with scleroderma who presented with signs of oral manifestations along with resorption at the angle of mandible, as well as widening of the periodontal space.
