目的：本研究评估了标准化的刮治次数与减少根面内毒素之间的关系。背景：牙周病涉及的牙齿的治疗试图通过刮治和根面平整去除附着物。从病因factors.Methods：24个提取的人类龋齿无单根牙至少5 mm的附着损失所需的机械治疗的量仍然未知。在每颗牙齿的根面上定义一个包含龈下牙石的感兴趣区域（ROI）。使用测力刮匙应用标准化力仪器。对每个ROI施加50个工作冲程。记录施加的力。将力记录从毫伏转换为牛顿（N）。在每5次中风后，评估结石的存在并收集鳞屑。结果中风1-5的内毒素值在统计学上显著大于所有其他中风间隔的值。平均9.3次中风后结石完全清除。内毒素浓度达到最低水平，浓度为0.03-0.306 EU/ml结石remove.Conclusion：这些研究结果表明，结石清除的完成与临床健康牙齿相关的内毒素水平相一致。
Objective: This study assessed associations between the number of standardized scaling strokes and the reduction of endotoxin on the root surface.Background: Therapy of periodontally involved teeth attempts removal of accretions by scaling and root planing. The amount of mechanical therapy required to free the root surface from etiologic factors remains unknown.Methods: Twenty-four extracted human caries-free single rooted teeth with at least 5 mm attachment loss were used. A region of interest (ROI) which contained subgingival calculus was defined on the root surface of each tooth. Standardized force instrumentation was applied using a force-measuring curet. Fifty working strokes were applied to every ROI. Forces applied were recorded. The force recordings were converted from Millivolts into Newtons (N). After every unit of 5 strokes, presence of calculus was evaluated and scaling debris was collected. Endotoxin concentration was determined in the debris samples.Results The endotoxin values for strokes 1-5 were statistically significantly greater than the values from all other stroke intervals. Complete calculus removal occured after a mean of 9.3 strokes. The endotoxin concentration reached a minimal level with concentrations of 0.03-0.306 EU/ml after calculus removal was complete.Conclusion: These findings suggest that completion of calculus removal coincides with endotoxin levels associated with clinically healthy teeth.
