目的:观察ProTaper手用镍钛锉联合EDTA凝胶在老年人磨牙根管治疗中应用的临床效果。方法:老年患者102颗磨牙,随机分为2组,每组51颗牙,实验组(PT)用ProTaper手用镍钛锉联合EDTA凝胶冠根向技术预备根管。对照组(SS)用不锈钢K型锉逐步后退法预备根管。两组均采用侧方加压法充填根管。记录根管治疗期间疼痛发生情况,根据X线片评价根管充填的效果。结果:PT组根管治疗期间疼痛发生率(5.88%)显著低于SS组(27.45%),PT组根管适充率(84.31%)明显高于SS组(62.74%),两组比较差异有统计学意义(P<0.05)。结论:ProTaper手用镍钛锉联合EDTA凝胶在老年人磨牙根管预备中有好的成形效果和较低的治疗间疼痛发生率。
Objective: To observe the clinical effect of ProTaper hand nickel-titanium file with EDTA gel in the treatment of geriatric molar root canal. Methods: 102 molars in the elderly were randomly divided into 2 groups with 51 teeth in each group. The experimental group (PT) was prepared with ProTaper hand nickel-titanium file and EDTA gel crown for root canal preparation. The control group (SS) with stainless steel K-file step by step retrograde preparation of root canal. Lateral compression method was used to fill the root canal in both groups. Record the occurrence of pain during root canal therapy, evaluate the effect of root canal filling according to X-ray. Results: The incidence of pain (5.88%) in PT group was significantly lower than that in SS group (27.45%), and that in PT group was significantly higher than that in SS group (84.31% vs 62.74%) There was statistical significance (P <0.05). CONCLUSIONS: ProTaper hand nickel-titanium files combined with EDTA gels have good formability and lower incidence of inter-treatment pain during root canal preparation in elderly patients.
