牙科电子麻醉在窝洞制备和开髓治疗中的应用

The analgesic effect of electronic dental anesthesia in cavity preparation and pulp treatment

目的 :评价牙科电子麻醉在窝洞制备和开髓过程中的镇痛效果。 方法 :对 6 0例窝洞制备患者和 15例开髓患者应用电子麻醉进行局部镇痛 ,另对 6 0例窝洞制备患者和 15例开髓患者应用传统局部麻醉作为对照 ,计算有效率 ,并对所得数值进行统计学处理 (χ2 检验 )。 结果 :窝洞制备组中 ,电子麻醉有效率为 93.33% ,局部麻醉有效率为 98.33% ,二者差异不显著 (P >0 .0 5 ) ;开髓治疗组中 ,电子麻醉有效率为 2 6 .6 7% ,局部麻醉有效率为93.33% ,二者差异显著 (P<0 .0 1)。 结论 :电子麻醉在窝洞制备时有良好的镇痛效果 ,但对开髓的镇痛效果并不理想。

Objectives: To evaluate the analgesic effect of electronic dental anesthesia(EDA). Methods: Sixty patients with dental caries in need of cavity preparation and 15 patients with pulpitis in need of pulp treatment were anesthetized with EDA, another 60 patients with dental caries in need of cavity preparation and 15 patients with pulpitis in need of pulp treatment were anesthetized with traditional local anesthesia(LA). Results: For patients with dental caries in need of cavity preparation, the effective rates in EDA group and LA group were 93.33% and 98.33 % respectively( P >0.05).For patients with pulpitis in need of pulp treatment ,the effective rates in EDA group and LA group were 26.7% and 93.33% respectively( P <0.01). Conclusions: EDA can be an effective analgesic method for cavity preparation, but not for pulp treatment.
