摘　　要：目的：探讨STA髓腔麻醉法在乳磨牙牙髓炎无痛治疗中的可行性。方法：将就诊的3~9岁儿童中,同颌对称同名乳磨牙明确诊断为乳磨牙牙髓炎的患儿22名（4-7岁）,共44颗患牙。每个患儿的2颗乳磨牙中,选取1颗采用STA髓腔麻醉,作为第1组（n=22）;另1颗采用STA常规麻醉,其中上颌采用颊侧骨膜上浸润麻醉,下颌采用牙周膜（PDL）麻醉作为第2组（n=22）。结果：髓腔麻醉注射时患儿的疼痛程度明显低于常规麻醉（P〈0.05）;1 min内开髓揭顶时的麻醉效果较高于常规麻醉。髓腔麻醉下治疗结束后均无软组织麻木感及无自伤性溃疡的发生,患儿对髓腔麻醉更易接受。结论：乳磨牙STA髓腔麻醉法镇痛效果优于传统浸润麻醉。Objective： To observe the effect of intrapulpal injection in the pulpectomy of primary molars. Methods： 22 petients with 44 diseased primary molars were divided into 2 groups （n = 22 teeth）. The intrapulpal injection with a computer-controlled local anesthetic delivery system STATM was performed in the experimental Group, and traditional infiltration anesthesia technique was conducted in the control group. Results： During the anesthesia process, the VAS value of the experimental group was lower than the control group（ P 〈 0.05 ）. The pain control in the experimental group was better during pulp removal within 1 min. There was no occurrence of postoper- ative soft tissue numbness and faetitial ulcer in the experimental group. Conclusion： The intrapulpal injection, administered with STATM , is more effective than traditional infiltration anesthesia in pulpectomy of primary molar teeth.
