摘　　要：目的评价牙周病患牙在采用不同治疗方法后根面内毒素存在情况及其数量变化。方法选择90个有严重骨吸收的单根牙周病患牙,拔除后随机分成3组。第1组为对照组,不作任何治疗;第2组用Gracey刮治器行刮治及根面平整术;第3组用新型超声装置Vector系统(Duerr Dental)行刮治及根面平整术。术后磨取各组患牙牙根表面物质,溶于水后用鲎试剂法定量检测内毒素浓度。结果对照组内毒素浓度为0.825EU/ml,Gracey组为0.240EU/ml,Vector系统组为0.184EU/ml。结论刮治和根面平整术可有效减少牙周病患牙根面内毒素含量。Objective To evaluate the quantity change of the root-bound endotoxin in periodontally-involved teeth by using different treatment modalities. Methods Ninety periodontally-involved single-root teeth with severe bone absorption were extracted and divided into 3 groups randomly. The first group served as the control group with no treatment. The second group was treated by scaling and root planning with Gracey scalers. Scaling and root planning for the third group was performed by using the Vector^TM system. Substance on the root surface was grounded after the treatment, and solved in water. The concentration of endotoxin was quantitatively measured by horseshoe crab. Results The concentrations of endotoxin were 0.825 EU/ml, 0.240 EU/ml and 0.184 EU/ml respectively for the control group, the Gracey group and the Vector group. Conclusions Scaling and root planning can effectively reduce the root-bound endotoxin in periodontally-involved teeth.
