摘要
目的 :探讨牙半切术在治疗下颌磨牙重度根分叉病变前后各项客观指标的变化 ,为该治疗方法的进一步应用提供依据。方法 :将 2 8个根分叉病变较为严重的下颌磨牙作为样本 ,进行牙半切术 ,保留相对较好的牙根。分别于术后 6、12、2 4个月对保留的牙根及其牙周指标 (PD、GI、SBI、PLI、PAL)进行测评。结果 :术后 2 8例患牙健侧根牙龈指数 (GI)和牙龈出血指数 (SBI) ,术后 6个月与术前相比有显著性差异 (P <0 .0 5 ) ,术后 6月与术后 12、2 4个月比较 ,牙周袋深度 (PD)有高度显著性差异 (P <0 .0 1) ,其余指标均无显著性差异 ,所保留的半切牙与对照组单根牙相比 ,PD、X线附着丧失有高度显著性差异 (P <0 .0 1)。结论
AIM:To investigate changes of the objective indicators before and after treatment of lesion in root furcation areas of mandibular molars by method of tooth hemisection in order to evaluate the applications of tooth hemi-section in this field.METHODS:28 teeth mandibular molars of serious lesion in root furcation were selected as samples and hemisected.The indicators of PD、GI、SBI、PLI、PAL were respectively tested 6,12 and 24 months after operation.RESULTS:Among the 28 teeth, the GI and SBI we significantly different ( P <0.05) before and 6 months after operation. At 6 months after operation the PD are extremely different ( P <0.01) to 12 months and 24 months after operation.The other indexes at 6 months,12 months and 24 months after operation all have no significant difference. The PD and X-ray attachment loss of hemi-sectioned teeth, compared with the control group, are extremely different ( P <0.01) .CONCLUSION:tooth hemisection is a effective and simple method to treat mandibular molar serious lesions in roots furcation.
