The purpose of this investigation was to determine the prevalence of the palato-gingival groove in maxillary incisor teeth and the health status of the lingual periodontal tissues adjacent to maxillary incisor teeth with and without the grooves. A total of 531 individuals aged 17 to 35 years were examined for the presence or absence of palato-gingival grooves in their maxillary incisor teeth. A Plaque Index (PII), Gingival Index (GI), and Periodontal Disease Index (PDI) were recorded for the lingual aspect of the four maxillary incisors. Tooth mobility was also recorded. The prevalence of the palato-gingival grooves in the 531 individuals examined was 8.5%. Of the 2,099 maxillary incisor teeth examined, 2.33% had a palato-gingival groove. Most of the palato-gingival grooves (93.8%) were in maxillary lateral incisor teeth. Statistical analyses revealed no differences in groove prevalence on the basis of sex or race. Results of the study also indicate that the palato-gingival groove is associated with poorer periodontal health as measured by the GI and PDI and more plaque accumulation as measured with the PII.
本研究的目的是确定上颌切牙腭龈沟的患病率，以及有和没有腭龈沟的上颌切牙舌侧牙周组织的健康状况。对531名年龄在17至35岁之间的个体进行检查，以确定其上颌切牙是否存在腭龈沟。记录了上颌四颗切牙舌侧的菌斑指数（PII）、牙龈指数（GI）和牙周疾病指数（PDI）。还记录了牙齿松动情况。在接受检查的531名个体中，腭龈沟的患病率为8.5%。在检查的2099颗上颌切牙中，2.33%有腭龈沟。大多数腭龈沟（93.8%）位于上颌侧切牙。统计分析显示，腭龈沟患病率在性别或种族方面无差异。研究结果还表明，根据GI和PDI测量，腭龈沟与较差的牙周健康状况相关，根据PII测量，腭龈沟与更多的菌斑积聚相关。
