To evaluate the gingival phenotypes of healthy young adult Pakistanis attending a dental institution.
A cross-sectional study of gingival phenotype, probing depth (PD), papilla height (PH), gingival width (GW), gingival thickness (GT), crown width (CW) and crown length (CL) of maxillary central incisors was conducted in 510 healthy, Pakistani young adults, aged 20-35 years, attending a regional dental hospital in Pakistan. The K-means clustering technique was employed to delineate clusters based on the characteristics of the periodontal phenotypes. The resultant data was compared with the available international findings.
Three quarters (76 %) of the 510 patients examined exhibited a thick gingival phenotype, and the remainder a thin phenotype. The K-means clustering deployed the individual into three different clusters 1, 2 and 3, with varying ratios of PD, GW, CW/CL, with significant variations across the three clusters (p < 0.05). Our data where a vast majority of the cohort exhibited a thick gingival phenotype is comparable to most of the populations sampled in other regions of the world.
Taken together the current data, a first for a Pakistani population, indicate that healthy, young adult Pakistanis had differing gingival phenotypes and crown forms, with the thick gingival phenotype predominating. These results are similar to reports from most other regions of the world. However, a larger study with a broader swathe of the Pakistani population is required to derive country specific data on the subject.
评估在一家牙科机构就诊的健康巴基斯坦年轻成年人的牙龈表型。
对510名年龄在20 - 35岁、在巴基斯坦一家地区牙科医院就诊的健康巴基斯坦年轻成年人的上颌中切牙牙龈表型、探诊深度（PD）、龈乳头高度（PH）、牙龈宽度（GW）、牙龈厚度（GT）、冠宽度（CW）和冠长度（CL）进行了横断面研究。采用K均值聚类技术根据牙周表型特征划分聚类。将所得数据与现有的国际研究结果进行比较。
在检查的510名患者中，四分之三（76%）表现出厚牙龈表型，其余为薄牙龈表型。K均值聚类将个体分为三个不同的聚类1、2和3，其PD、GW、CW/CL比例不同，三个聚类间存在显著差异（p < 0.05）。我们的数据显示绝大多数队列表现出厚牙龈表型，这与世界其他地区抽样的大多数人群相当。
综合目前的数据（这是针对巴基斯坦人群的首次研究）表明，健康的巴基斯坦年轻成年人有不同的牙龈表型和牙冠形态，厚牙龈表型占主导。这些结果与世界上大多数其他地区的报告相似。然而，需要对更广泛的巴基斯坦人群进行更大规模的研究，以得出关于该主题的特定国家数据。
