Multiple idiopathic root resorption is a rare disease in which the roots of multiple teeth are resorbed within a short period of time without any particulr cause. A 55-year-old woman was referred to our clinic with a chief complaint of discomfort in the right maxillary region. The radiographic examination revealed apical root resorption of 6 right maxillary teeth (from the central incisor to the first molar). The patient had no history of trauma. Segmental resection of the right maxillary alveolar bone including 6 teeth was performed. Histologically the soft tissue area showed proliferation of the fibrous connective tissue. The diagnosis was multiple idiopathic root resorption. After the operation, the prognosis was favorable without any sign of recurrence.
