The present investigation was designed to evaluate the long-term effect of root-resective therapy in the treatment of furcation-involved molars. The patient sample included 72 patients, 21-62 years of age, who presented periodontal lesions in the posteriors segments of the mouth including furcation involvement of various degrees. After an initial examination, each patient was subjected to a series of full-mouth scaling and root planing. They were recalled 1-3 months later for a presurgical examination and subsequently underwent the corrective phase of therapy. During the surgical procedure, the furcation-involved teeth were subjected to root-resective therapy in conjunction with osseous recontouring and apically positioned flaps (test sites). A surgical procedure identical to the test procedure was performed in the non-furcation-involved teeth (control sites) with the exception of the root resection. At the completion of the active phase of treatment, 175 test and 175 control sites were available for the study. After a period of 6 months of healing and plaque control supervision following surgical procedures, the patients were recalled for a baseline examination. They were then enrolled in a maintenance program including professional tooth cleaning every 26 months. The patients were re-examined 3, 5 and 10 years post-operatively. The results of the assessments demonstrated that the survival rate, during the 10-year period of observation, reached 93% at test and 99% at control sites. The positive treatment outcome at the root-resected, furcation-involved teeth as well as at non-furcation-involved teeth was probably the consequence of the reestablishment of a tissue morphology favorable for oral hygiene and careful plaque control by the patients.
本研究旨在评估根切除术治疗根分叉病变磨牙的长期效果。患者样本包括72名年龄在21至62岁之间的患者，他们口腔后部出现牙周病变，包括不同程度的根分叉病变。初次检查后，每位患者均接受了一系列全口洁治和根面平整。1至3个月后对他们进行术前检查，随后接受治疗的矫正阶段。在手术过程中，对根分叉病变牙齿进行根切除术，并结合骨修整和根向复位瓣（试验部位）。除根切除术外，对未发生根分叉病变的牙齿（对照部位）进行与试验手术相同的手术。在治疗的活跃期结束时，有175个试验部位和175个对照部位可供研究。在手术后6个月的愈合和菌斑控制监督期后，召回患者进行基线检查。然后让他们参加一个维护计划，包括每26个月进行一次专业牙齿清洁。在术后3年、5年和10年对患者进行复查。评估结果表明，在10年的观察期内，试验部位的存活率达到93%，对照部位为99%。根切除的根分叉病变牙齿以及未发生根分叉病变牙齿的积极治疗结果，可能是由于重建了有利于口腔卫生的组织形态，以及患者认真控制菌斑的结果。
