STA髓腔麻醉法在乳磨牙牙髓摘除术中的应用

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.

Clinical application of the intrapulpal injection with STATM anesthetic delivery system in pulpectomy of primary molars

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 postoperative soft tissue numbness and factitial ulcer in the experinental group.Conclusion:The intrapulpal injection,administered with STATM,is more effective than traditional infiltration anesthesia in pulpectomy of primary molar teeth.
