BACKGROUND A 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 *** grooves that extend to the root apex often lead to complex combined periodontal-endodontic *** are a serious challenge for doctors to diagnose and *** SUMMARY In 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 *** 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 *** this case,a combination of endodontic therapy,intentional replantation,and root resection were used,which resulted in periodontal/periradicular healing after 12 *** intentional 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.

Maxillary first molar with an O-shaped root morphology:report of a case

引用

International Journal of Oral Science 2013年第4期5卷 242-244页

作者： Yooseok Shin Yemi Kim Byoung-Duck Roh Microscope Center Department of Conservative Dentistry and Oral Science Research CenterCollege of DentistryYonsei University Department of Conservative Dentistry Ewha Womans University

This case report is to present a maxillary first molar with one O-shaped root, which is an extended C-shaped canal system. Patient with chronic apical periodontitis in maxillary left first molar underwent replantation because of difficulty in negotiating all canals. Periapical radiographs and cone-beam computed tomography （CBCT） were taken. All roots were connected and fused to one root, and all canals seemed to be connected to form an O-shape. The apical 3 mm of the root were resected and retrograde filled with resin-modified glass ionomer. intentional replantation as an alternative treatment could be considered in a maxillary first molar having an unusual O-shaped root.
