摘要
目的比较分析手术显微镜辅助下治疗五种疑难根管的疗效。方法收集2003年7月至2004年12月连续在我院确诊治疗的疑难根管共计359个,根据患者的意愿分为两组,显微根管治疗者为治疗组,计180个;传统治疗者为对照组计179个。对两组中的钙化不通根管、器械折断根管、MB_2根管、"C"形根管和再治疗根管的成功率,从统计学意义和临床意义两方面作以分析比较。结果从统计学意义分析,治疗组钙化不通根管、器械折断根管、MB_2根管、"C"形根管和再治疗根管的成功率分别是68.18%、71.43%、70.00%、83.33%和80.39%,比对照组相应疑难根管的成功率分别为13.33%、16.67%、25.00%、22.73%和38.46%高,差异有统计学意义(X^2分别是21.607、23.572、8.120、19.100和20.488,P分别是0.000、0.000、0.004、0.000和0.000.均P<0.01),从临床意义分析,钙化不通根管,器械折断根管,MB_2根管、"C"形根管和再治疗根管,其RR分别是0.3671、0.3429、0.4000、0.2157和0.3187,均RR<1;RRR分别是0.6329、0.6571、0.6000、0.7843和0.6813,均RRR>0;ARR分别是0.5485、0.5476、0.4500、0.6060和0.4193,均ARR>0,提示显微镜辅助下根管治疗可减少失败率,有利于患者。钙化不通根管、器械折断根管、MB_2根管、"C"形根管和再治疗根管,其NNT分别是1.8232、1.8262、2.2222、1.6502和2.3849,说明应用显微根管治疗.为治疗成功1个上述各种疑难根管,分别需治疗2、2、3、2和3个疑难根管。结论显微镜辅助治疗五种疑难根管成功率比传统治疗高。
Objective To analyze the effect of five kinds of complicated root canals therapy by utilizing surgical microscopes. Methods A total of 359 exactly diagnosed complicated root canals were consecutively treated from July 2003 to December 2004 in department of stomatology, No. 4 Affilicated Hospital of Inner Mongolia Medical College. The complicated root canals observed included calcified blocked root canals,instrument fracture root canals, MB2 root canals, “C” type root canals and retreated root canals. Two groups were randomly departed according to the patients＇ will. 180 complicated root canals were in the therapy group treated with surgical microscopes; in control group, 179 complicated root canals were treated by traditional root therapy methods without surgical microscopes. From two aspects of statistics and clinic, two groups＇ achievement ratios were compared. Results Statistically achievement ratios of five kinds of root canals in the therapy group were 68.18 % , 71.43 %, 70.00 %, 83.33 %, 80.39 % respectively, higher than those in the control group which were 13.33 %, 16.67 % ,25.00 % ,22.73 % and 38.46 % respectively. The differences had obvious statistical significance （X^2 = 21.607,23.572,8.120,19.100, 20.488 ; P=0.000,0.000,0.004,0.000,0.000, P 〈 0.01 ）. Clinical analysis revealed the RR of calcified blocked root canals, instrument fracture root canals, MB2 root canals, “C” type root canals and retreated root canals were respectively 0.3671,0. 3429,0. 4000,0. 2157,0. 3187. All the RR were less than 1. RRR were 0. 6329,0. 6571, 0.6000,0.7843,0. 6813.All RRR were more than 0. ARR were 0. 5485,0. 5476,0. 4500,0. 6060,0. 4193. All ARR were more than 0. It could be inferred that utilizing surgical microscopes could reduce the fail ratios of root therapy and was very helpful for the patients. The NNT were 1. 8232,1. 8262,2. 2222,1. 6502,2. 3849. It revealed that each completely successful case involved the treatment of at least 2 calcified blocked root canals, 2 instrument fracture root canals,3 MB2 root canals,2 “C” type root canals and 3 retreated root canals. Conclusion The achieve-ment ratios of five kinds of complicated root canals by utilizing surgical microscopes were much higher than those with the traditional root therapy methods.
