Controlled investigation reveals the significance of cone-beam computed tomography in diagnosing palatogingival groove issues in maxillary incisors, suggesting an interdisciplinary approach.
The palatogingival groove (PGG) was first described by Black in 1908, which originates from the palatal surface of the maxillary anterior teeth, from the cingulum, extending apically along the root surface up to varying lengths and depths. PGG-related disease is influenced by a number of variables, such as groove type, depth, range, and location, necessitating an interdisciplinary approach. Nevertheless, despite the high volume of case reports, no controlled investigations have been carried out. Here, we report such a challenging case of need of cone-beam computed tomography. for the diagnosis located in the maxillary central incisor and review the literature on the clinical and radiographic features of PGG.
