UNASSIGNED: Palatogingival groove (PGG) primarily affects maxillary lateral incisors and, when present, may contribute to the pathogenesis of periodontal and endodontic lesions.
UNASSIGNED: A total of 509 CBCT scans of Saudi patients with 2747 maxillary anterior teeth were included in the study. Patients\' information, the tooth type, the presence/absence, the unilateral/bilateral distribution, and the type of PGG according to Gu\'s classification (type I, II, or III) were recorded.
UNASSIGNED: The prevalence of the PGG in maxillary anterior teeth was 1.3%, affecting 32 (6.3%) patients. The PGGs were mostly detected in lateral incisors 25 (2.77%). The PGG was found to be unilateral in most patients (96.9%), with higher frequency in males than in females without significance for sex.
UNASSIGNED: PGG is not a rare anomaly in the Saudi population and is most frequently found in maxillary lateral incisors. Type I Gu\'s classification was mostly detected.
■颊沟(PGG)主要影响上颌侧切牙,当存在时,可能有助于牙周和牙髓病变的发病机制。
■这项研究共纳入了对沙特患者的509例CBCT扫描,其中有2747颗上颌前牙。病人信息,牙齿类型,存在/不存在,单边/双边分布,以及根据顾氏分类的PGG类型(I型,II,或III)被记录。
■PGG在上颌前牙中的患病率为1.3%,影响32例(6.3%)患者。PGG主要在侧切牙25(2.77%)中检测到。在大多数患者中发现PGG是单侧的(96.9%),男性的频率高于女性,对性别没有意义。
■PGG在沙特人口中并不罕见,最常见于上颌侧切牙。主要检测到I型Gu的分类。
