The purpose of the study was to radiographically evaluate the prevalence of palatogingival groove (PG) in the East Indian population in the maxillary anterior teeth in different genders, its unilateral/bilateral presentation, classified based on its radiographic characteristics, to determine the prevalence of different types, which could help in future treatment planning.
The design of the study was a retrospective study.
Analysis of 429 maxillary anterior teeth (144 central incisors, 145 lateral incisors, and 139 canines) in 72 cone-beam computed tomography scans was done (31 males and 41 females, mean age 27.3 ± 7.63). Demographic details of patients and characteristics of PG, i.e. location, extension, depth, and type, were recorded. The presence of alveolar bone loss and periapical pathology was noted.
An overall prevalence of PG was found to be 2.33% ( = 10), with PG being detected in 2 (1.388%) central incisors, 8 (5.51%) lateral incisors, and 0 (0%) canines. Eight of the patients had a unilateral presence, while one patient reported with bilateral presence, implying a significantly higher predilection of unilateral occurrence ( = 0.02). The prevalence was found to be higher in females ( = 8). The teeth were categorized as either having Type I (6 teeth), Type II (3 teeth), or Type III (1 teeth). Three of the 10 PGs were present in the mesial, six in the mid-palatal, and one in the distal portion of the palatal surface.
The prevalence of PG in the maxillary incisors in this cohort is 2.33%. The maxillary lateral incisors are the most affected teeth. Unilateral presentation is more common.
本研究旨在通过影像学评估东印度人群上颌前牙腭龈沟（PG）在不同性别中的患病率、其单侧/双侧表现，根据影像学特征进行分类，以确定不同类型的患病率，这有助于未来的治疗计划制定。
本研究为回顾性研究。
对72例锥形束计算机断层扫描中的429颗上颌前牙（144颗中切牙、145颗侧切牙和139颗尖牙）进行分析（31例男性和41例女性，平均年龄27.3±7.63岁）。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。记录牙槽骨吸收和根尖周病变的情况。
发现PG的总体患病率为2.33%（n = 10），其中在2颗（1.388%）中切牙、8颗（5.51%）侧切牙和0颗（0%）尖牙中检测到PG。8例患者为单侧存在，1例患者为双侧存在，这意味着单侧发生的倾向明显更高（P = 0.02）。发现女性中的患病率更高（n = 8）。这些牙齿被分类为具有I型（6颗牙齿）、II型（3颗牙齿）或III型（1颗牙齿）。10个PG中有3个位于腭侧近中，6个位于腭中，1个位于腭侧远中。
该队列中上颌切牙PG的患病率为2.33%。上颌侧切牙是受影响最严重的牙齿。单侧表现更为常见。
