目的:探讨上颌麻醉注射技术在拔除上颌阻生牙中的麻醉效果及减少腭侧不良反应的有效麻醉方法。方法:选择237例需要拔除上颌阻生牙齿的患者随机分为2组,试验组124例,对照组113例,治疗时分别采用新的上颌局部麻醉方法和传统治疗方法,对麻醉效果进行分析比较。结果:试验组与对照组麻醉注射时的疼痛明显差异有显著性(P<0.05)。试验组与对照组在拔牙手术中疼痛差异无显著性(P>0.05)。结论:采用新的上颌局麻方法具有操作简单易行,避免腭侧注射的疼痛与创伤的特点。
Objective: To investigate the anesthetic effect of maxillary anesthesia in the extraction of maxillary impacted teeth and the effective anesthetic method to reduce the palatal side reaction. Methods: A total of 237 patients with maxillary impacted teeth were selected and randomly divided into two groups. The experimental group (124 cases) and the control group (113 cases) were treated with new maxillary local anesthesia and traditional treatment respectively. The effects of anesthesia were compared . Results: There was a significant difference in pain between the two groups (P <0.05). There was no significant difference between the experimental group and the control group in the extraction of teeth (P> 0.05). Conclusion: The new method of maxillary local anesthesia is easy to operate and avoids the pain and trauma of palatal injection.
