【摘要】：目的： 通过测量河南省青年人上前牙区游离龈和牙龈乳头形态的相关参数数值，分析牙形与各牙龈形态参数间的相关关系、同一牙形在不同牙位间的差异以及各牙龈参数间的相关规律，为河南省青年人上前牙区牙龈参数的统一制定提供依据。 方法： 选取河南省青年人115例作为研究对象，采用精细藻酸盐印模材料获取牙列模型，，数显游标卡尺（精度0.01mm)测量与上前牙区牙龈形态相关的牙龈美学参数:牙龈角度（GA）、龈乳头高度(PH)、龈缘水平距离（GZL）、牙龈顶点（GZP）与牙冠长轴（VBM)的距离。根据上中切牙牙体形态，分为方圆形(41)，椭圆形(41)和尖圆形(33)3组,并对其测量结果用SPSS18.0进行统计分析。 结果： 1.测量得出了河南省青年人上前牙区GA、PH、GZL、GZP与VBM距离四组牙龈参数的相关数值。 2.侧切牙的GZL:男性女性；侧切牙的GZP偏向VBM远中的距离:男性女性。 3.三种牙形上前牙区的GA：方圆形椭圆形、尖圆形；PH:尖圆形椭圆形方圆形；GZP:中切牙、侧切牙偏向远中,尖牙在VBM上。 4.上前牙区不同牙位间的GA:尖牙中切牙侧切牙；PH:中切牙(CI－CI)侧切牙(CI-LI)尖牙(LI－CA);GZP偏向VBM远中的距离:中切牙、侧切牙尖牙。 5.方圆形、椭圆形、尖圆形的GA与相应的PH均存在线性相关性。 结论： 1.河南省青年人上前牙区GA、PH与上中切牙牙形密切相关；GZP、GZL与上中切牙牙形关系较小。性别对GZP、GZL的影响较大，对PH、GA影响较小。 2.在同一牙形中,河南省青年人上前牙区GA、PH、GZP在不同牙位间（中切牙、侧切牙、尖牙）中具有显著性的差异；GA与PH呈负性相关性。
[Abstract]:Objective: By measuring the relative parameters of free gingiva and gingival papilla of young people in Henan Province, the correlation between tooth shape and gingival shape was analyzed. The difference of the same tooth shape in different tooth position and the correlation rule among the gingival parameters provide the basis for the unified formulation of the gingival parameters in the premolar region of young people in Henan Province. Methods: 115 young people in Henan Province were selected to obtain dentition model with fine alginate impression material. The aesthetic parameters of gingival related to gingival morphology in anterior teeth were measured by digital display caliper (accuracy 0.01 mm): gingival angle, gingival papilla height, GZL, GZP and VBMs. According to the shape of the upper central incisor teeth, the teeth were divided into three groups, one group was divided into three groups, one group was the square round incisor, the other was the oval shape. The measured results were statistically analyzed by SPSS18.0. Results: 1. The gingival parameters of the four groups of GZP and VBM distance in the anterior teeth of young people in Henan Province were measured. 2. GZL of lateral incisor: male female; GZP of lateral incisor biased VBM distance: male female. 3. GA-: oblong oval, apical orbicular PH3: Apoid oval square round GZP: central incisor, lateral incisor is far away, canine is on VBM. 4. GZP between different positions of anterior incisor: central incisor: Ph: CI-CII) CI-LI) CI-LI) the distance of GZP bias to VBM is: central incisor, lateral incisor canine (CI-CII) CI-LI) the distance of GZP bias to VBM is: central incisor, lateral incisor canines. 5. There was a linear correlation between the square round, oval and pointed round GA and the corresponding PH. Conclusion: 1. There is a close relationship between GAPH and the shape of upper incisor in young people in Henan Province. The relationship between GZPU GZL and the shape of upper incisor is relatively small. Sex had a great influence on GZP GZL, but had little effect on PHG GA. 2. In the same tooth shape, the GZP of GAPH-GZP in the premolar region of young people in Henan Province was significantly different among different tooth positions (central incisor, lateral incisor, canine). There was a negative correlation between GA and PH.
