Root resorption associated with an impacted mesiodens: a surgical and endodontic approach to treatment

This article describes a case of root resorption of a maxillary non-vital immature incisor associated with an impacted and angulated mesiodens. The impacted tooth was surgically removed and the compromised incisor was subsequently endodontically treated. Over a period of 27 months the tooth was medicated with repeated applications of calcium hydroxide. Radiographically after 18 months, an incomplete hard tissue barrier was observed with full apical closure at the conclusion of 27 months of treatment. Once the patient was comfortable after surgical removal of the mesiodens, the tooth was asymptomatic and remained so for the duration of the treatment and after definitive restorative work had been completed.
