Palato-radicular groove is a rare developmental anomaly with prevalence rate of 2.8-8.5%. Most commonly affected tooth is the maxillary lateral incisor (93.8%). Palatoradicular groove may present as a radiolucent para pulpal line, radiographically. Treatment of radicular groove presents a clinical challenge to the operator. Removal of local predisposing factor is of prime importance. This case report presents the management of the periodontal defect associated with palatoradicular groove incorporating periodontal flap surgery with bone graft and GTR.

Introduction Periodontitis is an inflammatory disease primarily induced by bacteria. 1 The periodontal disease classification by the American Academy of Periodontology (AAP) recognizes tooth anomaly as one of the contributing factor. 2 Morphological defects in dental structure such as irregularities in root anatomy, developmental abnormalities, subgingival restoration margins, marginal ridge discrepancies, food impaction, cervical enamel projections, cemental tear, malalignment, furcation involvement, open contacts and overhanging dental restorations play a significant role in plaque trap, maturation, mineralization and byproducts retention leading to onset of inflammatory process in the periodontal and pulp tissues. Inherent anatomic and morphologic features of the teeth present diagnostic, prognostic and therapeutic challenges for the operator. 3 * Corresponding author.

Considering, the clinical significance and rare occurrence of the palato-radicular groove, this paper presents a case of palato-radicular groove on maxillary lateral incisor with associated periodontal and pulpal involvement, managed with a combined treatment protocol. 2. Case Report A 22 years old male patient presented with purulent discharge along the maxillary left lateral incisor which was present for the last one month. She did not give any history of trauma. The medical and family histories were non- contributory. Examination revealed extrusion and grade II mobility of maxillary left lateral incisor which was not associated with dental caries. Examination on distopalatal aspect revealed a localized pocket of 10 mm depth with pus discharge from the pocket (Figure 1). On careful examination and exploration, the palatogingival groove was detected on the distopalatal aspect which was extending into the gingival sulcus. Patient’s oral hygiene was fair. https://doi.org/10.18231/j.ijohd.2022.015 2395-4914/© 2022 Innovative Publication, All rights reserved. 72
