■该研究的目的是通过放射学方法评估不同性别的上颌前牙中东印度人群中的腭沟(PG)的患病率,其单边/双边陈述,根据其射线照相特征进行分类,为了确定不同类型的患病率,这可能有助于未来的治疗计划。
■本研究设计为回顾性研究。
■分析429颗上颌前牙(144颗中切牙,145个侧切牙,和139头犬)在72个锥形束计算机断层扫描中进行了(31个男性和41个女性,平均年龄27.3±7.63)。患者的人口统计细节和PG的特征,即位置,扩展,深度,和类型,被记录下来。注意到存在牙槽骨丢失和根尖周病理。
■发现PG的总体患病率为2.33%(n=10),在2个(1.388%)中切牙中检测到PG,8(5.51%)侧切牙,0(0%)犬。八个病人有一个单方面的存在,虽然一名患者报告有双侧存在,暗示单侧发生的倾向明显更高(P=0.02)。发现女性的患病率较高(n=8)。牙齿被归类为I型(6颗牙齿),II型(3齿),或III型(1齿)。10个PG中有3个存在于中部,6个在腭中段,和一个在腭表面的远端部分。
■上颌切牙中PG的患病率为2.33%。上颌侧切牙是受影响最大的牙齿。单方陈述更为常见。
UNASSIGNED: 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.
UNASSIGNED: The design of the study was a retrospective study.
UNASSIGNED: 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.
UNASSIGNED: An overall prevalence of PG was found to be 2.33% (n = 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 (P = 0.02). The prevalence was found to be higher in females (n = 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.
UNASSIGNED: 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.
