【摘要】：目的分析牙冠延长术中牙根暴露量对患牙远期疗效的影响。方法选取2010年8月至2012年10月于遵义医学院附属口腔医院接受牙冠延长术的110例患者,共142颗患牙,其中前牙66颗,前磨牙46颗,磨牙30颗。将所有患牙分为观察组与对照组,两组前牙、前磨牙、磨牙3个牙位的患牙均为33颗、23颗及15颗。观察组术中的牙根暴露量为3mm,对照组为4mm,比较两组术后的临床疗效。结果对照组术后3个月的前牙松动度要明显高于观察组(P0.05);两组其余患牙手术前后松动度比较,差异无统计学意义(P0.05);观察组术后3个月前牙、前磨牙及磨牙的出血指数要明显高于对照组(P0.05);两组其余时间患牙的出血指数比较,差异无统计学意义(P0.05);观察组与对照组所有患牙手术后牙周袋深度及附着丧失比较,差异无统计学意义(P0.05)。结论 3mm与4mm的牙根暴露量均能够在牙冠延长术中获得良好的临床疗效,但从美观的角度出发,前牙的牙根暴露量应取3mm。
[Abstract]:Objective to analyze the effect of root exposure on tooth root exposure on the long-term effect of the affected teeth. Methods from August 2010 to October 2012, 110 patients with 142 teeth, including 66 anterior teeth, 46 premolars and 30 molars, were selected from the Stomatological Hospital Affiliated to Zunyi Medical College. The teeth were divided into the observation group and the control group, and the two groups were divided into the observation group and the control group. The teeth of the anterior teeth, the premolar and the molar of the 3 teeth were all 33, 23 and 15. The root exposure in the observation group was 3mm, the control group was 4mm, and the clinical effect of the two groups was compared. Results the anterior teeth looseness of the control group was significantly higher than that of the observation group (P0.05) after 3 months of operation; the difference of the looseness of the other two groups before and after the operation was not statistically significant. The bleeding index of the teeth, premolar and molar in the observation group was significantly higher than that of the control group (P0.05) 3 months after the operation (P0.05), and there was no significant difference in the bleeding index between the other groups at the rest of the time (P0.05), and there was no significant difference between the observation group and the control group after the operation of the periodontal pocket and the loss of attachment (P0.05). Conclusion the root exposure of 3mm and 4mm can achieve good clinical effect in the crown lengthening, but from a beautiful point of view, the exposure of the root of the anterior teeth should be 3mm.
