The aim of the present study was to determine the facial gingival profiles of teeth with a healthy periodontium in an Asian population.
A total of 51 patients with a healthy periodontium were examined. Gingival thickness (GT) and gingival width (GW) were assessed at the maxillary and mandibular incisors to the first molars. GT was measured by transgingival probing (GT-TGP), and probe visibility through the marginal gingiva (GT-TRAN) was assessed. Results between groups (anterior and posterior, tooth types) were analyzed using one-way analysis of variance and t-test.
The mean age was 30.3±11.4 years, with 27 females and 24 males. The mean GT-TGP was 1.39±52 mm, while the mean GW was 4.59±1.34 mm. Considerable intra-individual and interindividual variation in GT (TGP and TRAN) was noted. GT increased from the anterior to posterior, and was thinnest at the mandibular centrals to the first premolars and maxillary canines. GT-TGP and GW were influenced by tooth type, plaque, recession, and TRAN, but not age, sex, or ethnicity. GW were recorded lowest at the mandibular canines and all premolars. Thin gingiva was recorded at 63.8%-92% (GT-TGP<1.5 mm) and 75%-90% (GT-TRAN) of the anterior teeth.
A high percentage of anterior teeth had thin marginal gingiva. There was poor agreement between GT-TGP and GT-TRAN.
本研究旨在确定亚洲人群中牙周健康牙齿的面部牙龈形态。
共检查了51例牙周健康的患者。对上颌和下颌从切牙到第一磨牙的牙龈厚度（GT）和牙龈宽度（GW）进行评估。通过龈沟内探针法测量GT（GT-TGP），并评估探针透过边缘龈的可视性（GT-TRAN）。使用单因素方差分析和t检验分析组间（前部和后部、牙齿类型）结果。
平均年龄为30.3±11.4岁，女性27例，男性24例。GT-TGP的平均值为1.39±52mm，而GW的平均值为4.59±1.34mm。注意到GT（TGP和TRAN）存在相当大的个体内和个体间差异。GT从前往后增加，在下颌中切牙到第一前磨牙以及上颌尖牙处最薄。GT-TGP和GW受牙齿类型、菌斑、牙龈退缩和TRAN的影响，但不受年龄、性别或种族的影响。GW在下颌尖牙和所有前磨牙处记录最低。在前牙中，63.8%-92%（GT-TGP<1.5mm）和75%-90%（GT-TRAN）的牙龈被记录为薄龈。
高比例的前牙边缘龈薄。GT-TGP和GT-TRAN之间的一致性较差。
