A new technique of a combined mechanical-chemical root preparation to enhance reattachment of pedicle grafts to previously denuded root surfaces is described. The clinical results of two documented cases are presented. The findings of this pilot study indicate that the technique is well tolerated by the patients, yielding a normal postoperative healing pattern and a clinical gain in the attachment level. These preliminary results may be attributed to: (1) Total elimination of bacterial endotoxin from the root surfaces by instrumentation and topical application of saturated citric acid at pH 1.0 for 3 minutes; (2) chemical exposure of dentin collagen fibrils, into which the graft may reattach; and (3) induction of cementogenesis by the exposed dentin.
本文描述了一种机械化学联合牙根预备新技术，以增强带蒂移植物与先前裸露牙根表面的重新附着。文中介绍了两个有记录病例的临床结果。这项初步研究的结果表明，该技术患者耐受性良好，术后愈合模式正常，附着水平有临床改善。这些初步结果可能归因于：（1）通过器械操作和局部应用pH值为1.0的饱和柠檬酸3分钟，完全清除牙根表面的细菌内毒素；（2）使牙本质胶原纤维发生化学暴露，移植物可重新附着其中；（3）暴露的牙本质诱导牙骨质生成。
