摘要
目的探讨倍骼生在Ⅱ度根分叉病变治疗中的疗效。方法 28例经过牙周基础治疗患者的36颗Ⅱ度根分叉病变患牙,随机分为:试验组18颗,行翻瓣术联合倍骼生植入术;对照组18颗,单纯行翻瓣术。术前及术后3、6、12个月检查牙周临床指标并进行定位根尖片检查。结果试验组牙周袋探诊深度(probing depth,PD)、附着丧失(attachment loss,AL)、根分叉水平探诊深度(horizontal probing depth,HPD)与基线比较,术后3个月(P<0.05)及术后6、12个月差异均有统计学意义(P<0.001);对照组PD、AL与基线比较,术后3、6、12个月差异均有统计学意义(P<0.05),HPD术后虽有改善但无统计学意义(P>0.05)。2组术后各时间点比较,PD(P<0.05)、AL(P<0.05)和HPD(P<0.001)差异均有统计学意义。结论应用倍骼生治疗Ⅱ度根分叉病变可获得比单纯翻瓣刮治更好的治疗效果。
Objective To observe the clinical effects of PerioGlas in the treatment of Grade Ⅱ furcation involvement.Methods Thirty-six teeth with Grade Ⅱ furcation involvement of 28 patients were selected.Four weeks after an initial therapy,they were randomly divided into two groups： PerioGlas group were treated with open flap debridement and graft of PerioGlas,and control group were treated with simple open flap debridement（OFD）.Clinical indicators of periodontal were examinated before operation and 3,6,12 months after operation.At the same time,standardized reproducible periapical films were taken.Results In PerioGlas group,significant improvements of all indexes can be observed in the3 months（P0.05）,even the 6 and 12 months after operation（P0.001）.In control group,PD,AL had significant difference（P0.05） at 3,6 and 12 months after operation,HPD had improved,but without statistically significance（P0.05）.Comparing the two groups after operation,PD,AL and HPD in different time points had significant difference（P0.05,P0.001）.Conclusion Better clinical efficacy was available when using PerioGlas in the treatment of Grade Ⅱ furcation involvement.
