Abstract：
UNASSIGNED: To investigate the prevalence of palatogingival groove (PGG) affecting maxillary anterior teeth, bilateral occurrence, and distribution among sex in the Saudi subpopulation and to review the literature on the prevalence of PGG.
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.

摘要：
■为了调查影响上颌前牙的腭龈沟（PGG）的患病率，双侧发生，以及沙特亚人群中性别的分布，并回顾有关PGG患病率的文献。
■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。
