Multiple idiopathic cervical root resorption (MICRR) is an aggressive and rare form of external root resorption that occurs at the cervical region of teeth that close to the cementoenamel junction and can affect multiple teeth (a minimum of 3) throughout the entire dentition. However, the etiology of this resorption remains elusive. No obvious clinical manifestation can be observed in the early stage of the disease, but the absorption may progress rapidly in a short time. Patients with this condition avoids biting because of pain and loosening of teeth. The affected crown separates from the root and leads to extraction. Recently, considerable attention has been paid to MICRR. This paper systematically reviews the pathogeny, pathogenesis, clinical manifestations, diagnosis, treatment, and prognosis of MICRR and provides a reference for clinicians.

Key words: root resorption, multiple, idiopathic, cervical root resorption
