| 摘 要： | 目的:评估牙周维护治疗在保持牙周治疗长期疗效中的作用。方法:对在北京大学口腔医院接受过牙周基础治疗的慢性牙周炎患者进行回顾研究,其中未接受维护治疗者22例,接受维护治疗者17例。临床检查包括牙周探诊深度(probing depth,PD)、牙龈出血指数(bleeding index,BI)、缺失牙数,并拍摄全口根尖片评价牙槽骨高度(骨根比值)。未维护治疗组的初诊和最后一次复诊的间隔时间平均为5.09年,维护治疗组平均为7.53年。比较初诊和最后一次复诊的上述各项临床指标。结果:未维护治疗组每人每年缺牙0.28颗,显著高于维护治疗组(0.09颗);复诊与初诊相比,未维护治疗组的PD值差异无统计学意义(4.13 mmvs.4.03 mm,P>0.05),而维护治疗组的PD值明显降低(4.02 mmvs.3.03 mm,P<0.05);未维护治疗组的牙槽骨骨根比由初诊时的59.15%下降到复诊时的54.76%,平均每年下降0.86%(P<0.05),而维护治疗组的牙槽骨骨根比复诊与初诊相比差异无统计学意义(60.51%vs.60.09%,P>0.05)。结论:牙周维护治疗不仅可以降低年缺失牙率、PD、BI,而且能明显减缓牙槽骨的进一步吸收,确保了基础治疗后效果的长期稳定。
