Treatment of endoperio lesion caused by palatogingival groove in maxillary lateral incisor: A case report

Radicular groove are one among the morphologic defects of the teeth, which have been reported as predisposing factors for periodontal disease. Palatogingival grooves may be of varied length and depth and once exposed to oral environment, bacterial plaque and calcified deposits may lodge in it. It acts as a plaque retentive area, and also impairs attachment of periodontal fibers, thus causing periodontal pocket formation. This article describe a case of male patient with palatogingival groove in maxillary lateral incisor, leading to periodontal pocket formation extending to periapical area, thus causing endoperio involvement. Tooth was well treated endodontically followed by periodontal intervention, including open flap debridement followed by regenerative procedure, along with apicocectomy and restoration of palatogingival groove.
