目的:对比分析次氯酸钠联合Nd:YAG激光与次氯酸钠单独用于牙髓炎患者根管消毒的临床疗效。
方法:将牙髓炎患者按照随机数字表法分为对照组和观察组。两组均接受根管治疗,对照组给予1%次氯酸钠根管冲洗。观察组采用1%次氯酸钠联合Nd:YAG激光灌注。牙周指数,炎症指数,比较两组患者治疗前和治疗3个月后的生活质量评分和细菌感染清除率。
结果:观察组总有效率为95.35%,高于对照组的79.07%(p<.05)。治疗3个月后,两组牙周指数和炎症水平均下降,观察组低于对照组(p<0.05)。观察组患者的生活质量评分和感染清除率均显著高于对照组(p<0.05)。
结论:与单独使用1%次氯酸钠的根管冲洗相比,合用次氯酸钠联合Nd:YAG激光进行根管消毒可显著提高治疗效果,缓解炎症反应,减少细菌感染。
To compare and analyze the clinical therapeutic effects of sodium hypochlorite combined with Nd: YAG laser and sodium hypochlorite alone for root canal disinfection in patients with pulpitis.
Patients with pulpitis were divided into control group and observation group according to random number table method. Both groups received root canal treatment, while the control group received root canal irrigation with 1% sodium hypochlorite. The observation group was irrigated with 1% sodium hypochlorite combined with Nd: YAG laser. Periodontal index, inflammatory index, life quality score and bacterial infection clearance rate of the two groups were compared before and 3 months after treatment.
The total effective rate of the observation group was 95.35%, which was higher than that of the control group 79.07% (p < .05). After 3 months of treatment, the periodontal index and inflammation level of both groups decreased, and the observation group was lower than that in the control group (p < .05). The life quality score and infection clearance rate of observation group were significantly higher than control group (p < .05).
Compared with root canal irrigation with 1% sodium hypochlorite alone, sodium hypochlorite combined with Nd: YAG laser for root canal disinfection can significantly improve the therapeutic effect, relieve inflammatory reaction, and decrease bacterial infection.
