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.
Retrospective study.
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.
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.
The prevalence of PG in maxillary incisors in this Indian cohort is 2.88%. Maxillary lateral incisors are the most affected teeth.
本研究旨在使用锥形束计算机断层扫描（CBCT）扫描调查印度人群上前牙腭龈沟（PG）的患病率。
回顾性研究。
对119例CBCT扫描（64例男性，55例女性，平均年龄31.6±13.5岁）进行分析。研究了636颗上前牙（220颗尖牙、212颗侧切牙和204颗中切牙）是否存在PG。记录患者的人口统计学细节以及PG的特征，即位置、范围、深度和类型。
在研究的636颗上前牙中，12颗（1.88%）牙齿检测到PG（3颗[1.47%]中切牙、9颗[4.2%]侧切牙，尖牙未检测到）。所有牙齿均被归类为具有I型（7颗牙）或II型（5颗牙）牙根沟。12处PG中有2处在近中，6处在腭中，4处在牙齿腭面远中部分。
该印度人群中上颌切牙PG的患病率为2.88%。上颌侧切牙是受影响最严重的牙齿。
