目的:探讨ProTaper根管扩大系统联合镍钛K锉在老年磨牙根管治疗中的应用价值。方法:收集2012年2月~2013年10月在我院口腔科就诊的156例急、慢性牙髓炎及根尖周炎的老年患者的临床资料,共发现患牙193颗,随机分为3组,A组60颗,B组64颗,C组69颗。A组采用ProTaper手动根管扩大系统联合镍钛K锉预备根管;B组采用ProTaper机动根管扩大系统联合镍钛K锉预备根管;C组采用不锈钢K锉预备根管。对适充率、填充满意率、急症反应发生率进行评定。结果:A、B、C组的适充率分别为为94.02%(110/117)、93.80%(121/129)、62.22%(89/143);A、B、C组的填充满意率分别为96.58%(113/117)、96.12%(124/129)、58.04%(83/143);A、B、C组急症反应发生率分别为4.27%(5/117)、4.65%(6/129)、26.57%(38/143)。A、B两组在适充率、填充满意率、急症反应发生率方面相比,无统计学差异(P>0.05),但分别与C组相比,均显著高于对照C组,差异有统计学意义(P<0.05)。结论:ProTaper根管扩大系统联合镍钛K锉在老年磨牙根管治疗中的疗效显著。
Objective: To explore the value of ProTaper root canal enlargement system combined with Nitinol K-file in the treatment of geriatric molar root canal. Methods: The clinical data of 156 elderly patients with acute and chronic pulpitis and periapical periodontitis who were treated in our department from February 2012 to October 2013 were collected. A total of 193 teeth were collected and randomly divided into 3 groups Group A 60, B 64, C 69. A group of ProTaper manual root canal expansion system combined with NiTi K file preparation of root canal; B group using ProTaper motorized root canal expansion system combined with NiTi K file preparation of root canal; C group using stainless steel K file preparation of root canal. Appropriate filling rate, filling satisfaction rate, the incidence of emergency response assessment. Results: The filling rates of A, B and C groups were 94.02% (110/117), 93.80% (121/129) and 62.22% (89/143) The incidences of acute illness were 96.58% (113/117), 96.12% (124/129), 58.04% (83/143) respectively. The incidences of acute reactions in groups A, B and C were 4.27% (5/117) and 4.65% (6 / 129), 26.57% (38/143). There was no significant difference between the two groups (P> 0.05), but there was no significant difference between the two groups (P> 0.05), but they were significantly higher than those in C group Statistical significance (P <0.05). Conclusion: ProTaper root canal enlargement system combined with nitinol K file in the treatment of geriatric molar root canal treatment has a significant effect.
