Abstract :
Introduction. The radicular groove is a developmental groove which is usually found on the palatal or lateral aspects of the
maxillary incisor teeth. The present case is a maxillary lateral incisor with a small second root and a deep radicular groove. The
developmental groove caused a combined periodontal-endodontic lesion. Methods. Case was managed using a combined treatment
procedure involving nonsurgical root canal therapy and surgical periodontal treatment. After completion of root canal treatment,
guided tissue regeneration (GTR) was carried out using decalcified freeze dried bone allograft (DFDBA) and a bioabsorbable
collagenous membrane. Tooth also was splinted for two months. Results. After 12 months the tooth was asymptomatic. The
periapical radiolucency disappeared and probing depth did not exceed 3 mm. Conclusion. Combined treatment procedure involving
nonsurgical root canal therapy and surgical periodontal regenerative treatment can be a predictable technique in treating combined
endodontic-periodontal lesions caused by radicular groove.
