目的:评估口腔无痛麻醉仪(STA)减轻患者疼痛的临床疗效。方法:选择临床病例100例随机分配至实验组和对照组各50例,对照组用传统的注射器采用传统方法注射麻醉,实验组用STA在牙周膜内注射麻醉,麻醉药物均用必兰麻,麻醉4min舌面穿髓治疗。采用疼痛视觉模拟量表(VAS)统计注射时和穿髓时疼痛程度。结果:实验组与对照组注射麻药时的VAS值差异明显(P<0.05),穿髓时VAS值差异不明显(P>0.05)。结论:使用STA无痛麻醉仪在前牙牙髓炎治疗中能有效减轻患者疼痛,值得在临床上推广应用。
Objective: To evaluate the clinical efficacy of oral painless anesthesia (STA) in reducing pain in patients. Methods: A total of 100 clinical cases were randomly divided into experimental group and control group, 50 cases in each group. The control group was anesthetized by traditional injection method with conventional injection method. The experimental group was anesthetized with periodontal ligament injection by anesthesia. , Anesthesia 4min lingual pulp treatment. Pain visual analog scale (VAS) was used to measure the degree of pain at the time of injection and the time of penetration. Results: There was significant difference in VAS between experimental group and control group (P <0.05). The VAS value was not significantly different between the experimental group and control group (P> 0.05). Conclusion: The use of STA painless anesthesia instrument in the treatment of anterior pulpitis can effectively reduce the pain of patients, it is worth in the clinical application.
