目的

探讨疏通磨牙弯曲钙化根管的治疗方法。

方法

实验组选取70 例患者72 颗磨牙根管中、重度弯曲且下段钙化堵塞的根管136 个,采用C 型先锋锉结合乙二胺四乙酸(EDTA)制剂分次疏通弯曲钙化根管,机动镍钛根管器械扩大并行冷牙胶侧压充填根管。对照组选取70 例患者74 颗磨牙中根管中、重度弯曲且下段钙化堵塞的根管139 个,采用K 锉结合EDTA 制剂分次疏通弯曲钙化根管,机动镍钛根管器械扩大并行冷牙胶侧压根管充填。

结果

实验组136 根管中有114 根管疏通成功并完成根管治疗,弯曲钙化根管疏通成功率为83.8%,无根管偏移、台阶形成、根管壁侧穿及器械折断发生。对照组139 根管中有70 根管疏通成功并完成根管治疗,弯曲钙化根管疏通成功率为50.4%,8 个根管发生根管偏移及台阶形成,未发生根管壁侧穿及器械分离。

结论

C 型先锋锉与EDTA 相结合,采用分次疏通技术,可作为临床上治疗磨牙弯曲钙化根管的有效方法。

Objective

To evaluate the negotiating and shaping ability of C-Pilot files and ethylenediaminetetraacetic acid (EDTA) in molar curved and calcified root canals.

Methods

Experimental group: 72 teeth with 136 moderately or severely curved and calcified canals in 70 patients were negotiated by C-Pilot files and EDTA in multiple visits, and then prepared with ProTaper rotary instruments and obturated with lateral condensation method.Control group: 74 teeth with 139 moderately or severely curved and calcified canals in 70 patients were negotiated by K files and EDTA in multiple visits, then prepared with ProTaper rotary instruments and obturated with lateral condensation method.Pre- and postoperative radiographs were compared to evaluate the treatment outcome.

Results

Experimental group: by using C-Pilot files and EDTA,114/136 moderately or severely curved and calcified canals were successfully prepared and obturated.The original canal curvature were respected and no transportation, ledge, perforation or instrument seperation was recorded.Control group: by using K files and EDTA, 70/139 moderately or severely curved and calcified canals were successfully prepared and obturated.However, 8 canals ended with transportation and ledge.No perforation or instrument seperation was recorded.

Conclusions

Using C-Pilot files combined with EDTA in multiple visits could be an effective way in negotiating curved and calcified root canals in molars.
