| 目的 评价根管超声冲洗技术对成人磨牙慢性牙髓炎一次法根管治疗术短期疗效的影响。方法 168 颗患牙按掷硬币的方法分为超声冲洗组86 颗和常规组82 颗,局麻下开髓、拔髓和根管预备,根管充填前常规组用2 mL 5.25% 的次氯酸钠溶液冲洗;超声冲洗组用2ml5.25% 次氯酸钠溶液注入根管,15号超声锉荡洗2min,期间不断补充新鲜液体。2组最后均使用17% EDTA 冲洗,吸干热牙胶垂直加压充填根管,窝洞暂封。3 天后复诊完成冠部充填。治疗后观察根管充填质量及侧枝根管充填情况、3天内疼痛发生情况以及1年后的治疗疗效。结果 超声组术后即刻侧支根管充填率提高,两组差异有统计学意义(P<0.05);根管充填后3 天内超声组疼痛发生率明显低于常规组(P<0.05);2 组1 年后疗效差异无统计学意义(P>0.05)。结论 超声冲洗能短期内降低术后疼痛发生率,提高侧支根管充填率,有很好的临床应用效果。 |

| Objective To assess the efficacy of ultrasonic irrigation on the one-visit root canal therapy of the Chronic pulpitis. Methods A total of 168 teeth were randomly divided into two groups (convention group 82, and ultrasonic irrigation group 86) according to the coin. Two groups were placed rubber dam after local anesthesia and instrumented by rotary nickel-titan protaper. Before the filling the ultrasonic irrigation group teeth were irrigated for 2 minutes used 15 ultrasonic file in 5.25% sodium hypochlorite solution; while the convention group teeth were irrigated by syringe as control. Finally the two groups were irrigated by 17% EDTA and filling by hot gutta-percha vertical. The postoperative pain after one-year successful rate were evaluated. The quality of root canal obturation, the number of lateral canals obturated, the postoperative pain during three days, One-year curative effect were obsened. Results The density of the obturation of lateral canals after the ultrasonic inrigation have been improved (P<0.05). There were significant differences between the two groups in postoperative pain after three days (P<0.05). One year later, no significant difference in clinical efficacy (P>0.05). Conclusion Ultrasonic irrigation could obviously decrease postoperative pain and improve the quality of root canal obturation. So the ultrasonic irrigation is a favorable technique for root canal therapy. |
