Abstract

Background: The objective of this study was to assess the prevalence and morphometric characteristics of the genial tubercle (GT) in a Turkish population using cone-beam computed tomography (CBCT), by classifying the morphology of GTs and evaluating their width, height, and anatomical position, in relation to age and sex.

Methods: A total of 356 CBCT images were collected from the radiology archive at Hacettepe University Faculty of Dentistry, involving 228 female and 128 male patients aged 18 years and older. The GTs were identified and classified using multiplanar reconstruction sections. Measurements taken included the width (GT-w) and height (GT-h) of the GTs, the distance from the GTs to the apex of the mandibular central incisors (I-SGT), the distance to the mandibular base (IGT-M), and the mandibular anterior thickness (MT).

Results: The overall prevalence of GTs was found to be 90.4%, with 9.6% of patients showing no GTs present. The most frequently observed type was GT-3 (33.1%), while the least common was GT-5 (9.6%). A statistically significant relationship was found between GT types and sex, as well as age groups (p = 0.007 and p = 0.017, respectively). Measurements indicated that the GT-w, GT-h, I-SGT, and MT values for males were greater than those for females.

Conclusions: The GTs exhibited significant variation in morphology according to age and sex, with GT-3 being the most common type and detectable GTs present in over 90% of individuals. Male participants demonstrated greater GT-w, GT-h, and MT values than females. The subdivision of Type 4 into 4 A and 4B provided a more detailed radiological characterization, which may serve as a useful reference in future anatomical and clinical research. CBCT images provide detailed information regarding the morphological assessment of GTs.

通过CBCT检测和煦结核的患病率和形态特征：来自土耳其人群的证据。

背景：本研究的目的是利用锥束计算机断层扫描（CBCT）评估土耳其人群中亲切结节（GT）的患病率和形态特征，方法是对GT的形态进行分类，并评估其宽度、高度和解剖位置与年龄和性别的关系。方法：从Hacettepe大学牙科学院放射学档案中收集CBCT图像356张，其中女性228张，男性128张，年龄在18岁及以上。利用多平面重建切片对GTs进行了识别和分类。测量结果包括：截齿宽度（GT-w）和高度（GT-h）、截齿到下颌中切牙尖的距离（I-SGT）、截齿到下颌基的距离（IGT-M）和下颌前壁厚度（MT）。结果：GTs的总患病率为90.4%，其中9.6%的患者未出现GTs。最常见的是GT-3型（33.1%），最不常见的是GT-5型（9.6%）。GT类型与性别、年龄组之间存在显著性相关（p = 0.007、p = 0.017）。测量结果表明，雄性的GT-w、GT-h、I-SGT和MT值大于雌性。结论：根据年龄和性别，GT-3型是最常见的类型，90%以上的个体存在可检测到的gt。男性受试者的GT-w、GT-h和MT值高于女性。将4型划分为4a型和4B型提供了更详细的影像学特征，可为今后的解剖和临床研究提供有用的参考。CBCT图像提供了GTs形态学评估的详细信息。试验注册：不适用。
