Intentional replantation combined root resection therapy for the treatment of type III radicular groove with two roots: A case report.

Abstract

BACKGROUNDA radicular groove is an anatomic malformation that usually initiates at the central fossa, extending along the root at varying lengths and depths and predisposes the involved tooth to a severe periodontal defect. Severe grooves that extend to the root apex often lead to complex combined periodontal-endodontic lesions. They are a serious challenge for doctors to diagnose and treat. CASE SUMMARYIn this report, we described a patient with a maxillary lateral incisor with a deep palatogingival groove with two roots, which led to complex combined periodontal-endodontic lesions. Suggested treatment modalities included curettage of the affected tissues, elimination of the groove by grinding and/or sealing with a variety of filling materials, and surgical procedures. In this case, a combination of endodontic therapy, intentional replantation, and root resection were used, which resulted in periodontal/periradicular healing after 12 mo.CONCLUSIONIntentional replantation and root resection offer a predictable procedure and should be considered a viable treatment modality for the management of palatogingival grooves, especially for two-rooted teeth.
