摘　　要：目的:应用不同龈壁处理方式及成形系统对龈下深龋行邻面边缘提升术,观察充填后对牙周探诊出血的影响,为龈下深龋充填提供参考。方法:将36例龈下深龋病例分别采用排龈术、电刀切龈术、翻瓣术,将龈下缺损提升至龈上,完成复合树脂直接充填。术后3个月复查牙周探诊出血(bleeding on probing,BOP)。通过单因素分析及最优标度初步判断性别、年龄、牙齿类型、成形片种类、牙髓活力、处理方式对BOP的影响,建立非条件Logistic回归模型筛选影响BOP的因素。结果:成形片种类影响BOP(P=0.009),个性化修剪的Ivory型成形片比分段式成形片的探诊出血率高。年龄、性别、牙齿类型、牙髓活力及处理方式对BOP均无显著影响(P>0.05)。结论:成形片种类影响BOP,排龈术、电刀切龈术、翻瓣术3种龈壁暴露技术未对BOP造成明显影响。Objective:To observe the effect of proximal margin elevation on periodontal probing bleeding in patients with deep subgingival caries by using different gingival wall treatments and matrix systems.Methods:Thirty-six cases with deep subgingival caries were treated with gingival retraction,electrosurgical gingivotomy,and flap surgery,respectively to elevate the subgingival defect above the gingiva and complete the direct filling with composite resin.Three months after the treatments,the patients were examined the bleeding on probing(BOP).The effects of gender,age,tooth type,type of matrixs,pulp vitality,and treatment on BOP were preliminary determined by univariate analysis and optimal scale.Unconditional logistic regression model was established to screen the factors affecting BOP.Results:The type of matrixs affected BOP(P=0.009):the bleeding rate of personalized trimmed Ivory matrix was higher than that of segmented matrix.Age,gender,tooth type,pulp vitality,and treatment had no significant effect on BOP(P>0.05).Conclusion:The type of matrixs affect BOP.Gingival retraction,electrosurgical gingivotomy,and flap surgery had no significant effect on BOP.
