Prevalence of palatogingival groove affecting maxillary anterior teeth in Saudi subpopulation: A cone-beam computed tomographic study with literature review.

Aim: To investigate the prevalence of palatogingival groove (PGG) affecting maxillary anterior teeth, bilateral occurrence, and distribution among sex in the Saudi subpopulation and to review the literature on the prevalence of PGG.

Introduction: Palatogingival groove (PGG) primarily affects maxillary lateral incisors and, when present, may contribute to the pathogenesis of periodontal and endodontic lesions.

Materials & Methods: A total of 509 CBCT scans of Saudi patients with 2747 maxillary anterior teeth were included in the study.
