传统根尖外科手术与显微根尖外科手术的效果评价

Retrospective Study on the Effectiveness of Root-end Surgery Performed with Traditional and Ultrasonic Instruments

目的:比较传统根尖外科手术与显微根尖外科手术的术后疗效。方法:采集既往实施根尖外科手术病例76例,根据使用手术器械不同分为两组,A组:传统器械组38例:B组:显微超声器械组38例,两组采用同种根尖倒充填材料。根据临床及X线判定标准判定术后疗效,分为完全愈合、不完全愈合、不确定愈合、失败四组,统计术后一年手术成功率。结果:统计结果表明,B组术后成功率显著高于A组(P<0.05)。结论:采用现代显微超声器械术后疗效明显优于传统器械。

Objective： To compare the effects of root-end operations performed with traditional and and ultrasonic instruments.Methods： 76 cases which had received root apical operation were collected.According to the different instruments,these cases were divided into two groups： group A（38 cases）： traditional instrument;group B（38 cases）：microscopic and ultrasonic instrument.The root canals of both groups were filled with the same retrograde filling material.The effects were evaluated by clinical and radiographic checkup. According to the results of the checkups, the cases were divided into four groups： Complete healing, Incomplete healing, Uncertain healing and Failure. After one year. Results： The statistical results indicated that the success rate of group A was significantly higher than that of group B （P 〈 0.05 ）. Conclusion ： The effectiveness of microscopic and ultrasonic instrument is superior to that of traditional one.
