Aim: This study aims to investigate the prevalence of palatogingival groove (PG) in anterior maxillary teeth in an Indian cohort using cone beam computed tomography (CBCT) scans.
Study Design: Retrospective study.
Materials and Methods: Analysis of 119 CBCT scans (64 males, 55 females, and mean age 31.6 ± 13.5 years) was performed. The data of 636 anterior maxillary teeth (220 canine, 212 lateral incisor, and 204 central incisor teeth) were studied for PG's presence. Demographic details of patients and characteristics of PG, i.e., location, extension, depth, and type were recorded.
Results: Out of the 636 anterior maxillary teeth studied, PGs were detected in 12 (1.88%) teeth (3 [1.47%] central incisors, 9 [4.2%] lateral incisors, and 0 canines). All the teeth were categorized as having either type I (Seven teeth) or type II (Five teeth) radicular groove. Two of the 12 PGs were present in the mesial, six in the mid-palatal, and four were present in the distal portion of the palatal surface of the teeth.
Conclusions: The prevalence of PG in maxillary incisors in this Indian cohort is 2.88%. Maxillary lateral incisors are the most affected teeth.
