Healing of External Inflammatory Root Resorptions and Periapical Lesions without Surgical Treatment in an Operated Oblique Facial Cleft Case

This paper describes an operated oblique facial cleft case with external inflammatory root resorption (EIRR) of the permanent maxillary left incisors and canine in a 12-year old patient. Due to the facial oblique cleft, the plastic surgery department operated on the patient five times and placed her on fixed orthodontic therapy. EIRR treatment of the maxillary left incisors and canine was performed using long-term calcium hydroxide therapy. The permanent root canal fillings of the lateral incisor and canine were performed using conventional gutta percha fillings. Because no sufficient apical barrier stop of the central incisor occurred, it was filled with Mineral Trioxide Aggregate (MTA); the canine crown fracture was restored using a carbon-covered fiberglass post and a light-cured composite resin. Examination after 42 months revealed good esthetics and no periapical pathology.
