The aims of this study were to determine the microbiological and particle size characteristics of particulate bone collected with a piezosurgery device and bone trap, and to reduce bacterial contamination after treatment of debris with rifamycin SV. Samples were taken from 10 patients who underwent surgical extraction of their third lower molars. The ostectomy was performed with a piezosurgery device, and the debris was collected with a surgical aspiration set equipped with a bone trap. Two aliquots were taken from each sample, one of which was treated with rifamycin SV. The second aliquot, used as a control, was treated with a physiological solution. In the samples immersed in antibiotic solution, there was a statistically significant (P<0.005) reduction in bacterial contamination. The stringent protocol followed in this study has proved valid for collection of material, and treatment with rifamycin SV was found to reduce bacterial contamination in collected material.
本研究的目的是确定使用压电手术设备和骨收集器收集的颗粒状骨的微生物学和粒度特征，并在用利福霉素SV处理碎片后减少细菌污染。样本取自10例接受下颌第三磨牙手术拔除的患者。使用压电手术设备进行骨切除术，并用配备骨收集器的手术抽吸装置收集碎片。从每个样本中取出两份等分试样，其中一份用利福霉素SV处理。用作对照的第二份等分试样用生理溶液处理。在浸入抗生素溶液的样本中，细菌污染有统计学意义的降低（P<0.005）。本研究遵循的严格方案已被证明对材料收集有效，并且发现用利福霉素SV处理可减少收集材料中的细菌污染。
