Study on the short-term efficacy of one-time root canal therapy for chronic pulpitis in adult posterior teeth using root canal ultrasound irrigation technology
根管超声冲洗技术对成人后牙慢性牙髓炎一次法根管治疗术短期疗效的影响研究

摘要

目的 分析根管超声冲洗技术对成人后牙慢性牙髓炎一次法根管治疗术短期疗效的影响。方法 纳入我院2022年1月~2024年1月内进行一次法根管治疗术的成人后牙慢性牙髓炎患者70例，使用随机数字表法分为对照组（根管常规冲洗）和观察组（根管超声冲洗技术）各35例，对比两组临床疗效。结果 治疗前两组疼痛、牙周情况和咀嚼功能均无统计学意义（P＞0.05）。治疗后3d、7d、14d，观察组疼痛评分均较对照组更低；牙周指标均低于对照组；咀嚼功能指标均优于对照组。上述结果差异均存在统计学意义（P＜0.05）。结论 行根管超声冲洗技术对成人后牙慢性牙髓炎一次法根管治疗术治疗患者能够减轻术后疼痛，优化牙周情况，提高咀 嚼功能。

Abstract

Objective To analyze the effect of root canal ultrasound irrigation technology on the short-term efficacy of one-time root canal therapy for chronic pulpitis in adult posterior teeth.
Methods Seventy adult patients with chronic pulpitis in posterior teeth who underwent root canal therapy in our hospital from January 2022 to January 2024 were included. They were randomly divided into a control group (conventional root canal irrigation) and an observation group (ultrasonic root canal irrigation technique), with 35 cases in each group, using a random number table method. The clinical efficacy of the two groups was compared.
Results There was no statistically significant difference in pain, periodontal condition, and chewing function between the two groups before treatment (P>0.05). On days 3, 7, and 14 after treatment, the pain scores in the observation group were lower than those in the control group; Periodontal indicators were lower than those in the control group; Chewing function indicators were superior to the control group. The above results showed statistically significant differences (P<0.05).
Conclusion   Performing root canal ultrasonic irrigation technology can alleviate postoperative pain, optimize periodontal condition, and improve chewing function in adult patients with chronic pulpitis treated with one-time root canal therapy.
