目的:观察EXPASYL排龈膏法在不同牙龈指数(gingivalindex,GI)龈下牙体缺损充填修复中的排龈效果及远期疗效。方法:将152例(180颗牙)累及龈下的Ⅱ类洞按照不同GI分级原则,随机分为对照组、G1、G2 3组,对每组排龈临床效果及两年内充填体的脱落率进行对比分析。结果:不同牙龈指数的排龈效果及远期修复效果相同,差异无统计学意义。结论:GI指数≤2时,排龈效果及远期修复效果理想。
Objective: To observe the gingival curative effect and long-term curative effect of EXPASYL gingival crevicular paste in filling and repairing different gingival index (GI) subgingival defects. Methods: 152 cases (180 teeth) involving subgingival class Ⅱ hole according to the principle of different GI grading, were randomly divided into control group, G1, G2 group, the clinical effect of each row of gingival retraction and the filling rate of exfoliation within two years For comparative analysis. Results: The different gingival index of gingival retraction and long-term repair effect the same, the difference was not statistically significant. Conclusion: GI index ≤ 2, the gingival effect and long-term repair effect is ideal.
