Abstract
This case report represents the clinical management of tooth with palato-gingival groove in a right maxillary lateral incisor with endo-perio lesion leading to dento-alveolar abscess and sinus tract. The right maxillary lateral incisor was examined clinico-radiographically. On clinical examination, the offending tooth revealed localized swelling and an intraoral draining sinus pointing on the labial gingiva without any evidence of caries, discoloration and trauma. The palatal surface of lateral incisor showed a groove with mild calculus embedded in it. The radiographic examination revealed periapical radiolucency. This case provides an evidence of morphological defect of tooth. Complete clinical and radiological examination and adequate knowledge of such morphological/ developmental defects of teeth are necessary for recognition and identification especially because of their diagnostic complexity and further consequences.
Highlights
Maxillary lateral incisors are located in those regions are considered to be the areas of embryological danger.[1]
Patient presented with true endodontic involvement, as an earlier manifestation of palato-gingival groove
Palato-gingival groove is an enigma and it is considered as a silent killer that can pose dilemmas for diagnosis and clinical management
Summary
Maxillary lateral incisors are located in those regions are considered to be the areas of embryological danger.[1]. One more anomaly occurring in that area is palato-gingival groove It is one such morphological defect, most frequently found on the palatal surface of the maxillary lateral incisors.[2] to mild, moderate and complex. The palato-gingival groove is formed and has been speculated to an aborted formation of additional root.[3] The palatogingival groove has the likeness to dens invaginatus Both of them occurs due to an infolding of the epithelium, where the palato-gingival groove resulting in a groove and an invagination resulting in a circular opening.[4] The name of this anomaly has a wide range of diversity like the palato-gingival groove, the radicular lingual groove, the palatoradicular groove, the facial-radicular groove, and the disto-lingual groove.[5]. Based on depth and extention, the palato-gingival groove can be classified in
