| 摘 要： | 目的:明确影响术后天然牙根牙龈龈乳头的主要因素,为临床治疗提供依据。方法:需行上前牙翻瓣术的20名患者的46例上前牙龈乳头,记录术前菌斑指数、探诊深度、出血指数、龈乳头指数,记录术中乳头处龈瓣的厚度、邻面骨嵴顶至邻牙切角的距离(残根)/邻面骨嵴顶至邻接点的距离a(天然牙)、两牙根在骨嵴顶水平的近远中向距离、邻面骨嵴顶与唇侧骨嵴顶最根方的垂直距离,骨嵴顶颊舌向宽度和术后6个月修复位点恢复的邻接点与邻牙切角距离、PIS、PLI、PD、BI。单因素分析各临床指标与PIS的关系,Logistic回归分析各临床指标对PIS的影响。结果:随着邻面骨嵴顶至邻接点的距离的增加,龈乳头指数和充满率呈下降趋势,多因素分析显示,调整PD、BI、PLI后,邻面骨嵴顶至邻接点的距离是影响PIS的重要因素(OR=0.43,95%CI 0.184-0.99,P=0.047)。薄生物型的牙龈乳头体积显著小于厚生物型牙龈乳头体积(16.8±7.63 vs 27.96±9.89 mm3P<0.001)。结论:邻面骨嵴顶到邻接点的距离是影响牙龈乳头指数的主要因素,不同生物型牙龈龈乳头体积不同。

| Abstract: | Objective:To analyze the factors affecting the gingival papilla in front of maxillary anterior teeth with natural roots,so as to provide proof for clinical therapy.Methods:46 maxillary anterior papilla of 20 patients underwent flap surgery were studied.In which 26 papilla adjacent to natural intact teeth and 20 to teeth to be restorated.Plaque Index(PLI),probing depth(PD),bleeding index(BI) and papilla index score(PIS) were recorded before surgery.Thickness of gingival papilla were measured with electrical ... |
