摘要 目的:探讨无痛麻醉注射仪实施牙周韧带(PDL)麻醉开展拔牙术的可行性及效果。方法:收集拔牙病例共224例,以无痛麻醉注射仪实施PDL麻醉开展拔牙手术,了解麻醉效果,并比较上、下颌拔牙PDL麻醉效果的差异以及在炎症、非炎症状态下拔牙PDL麻醉效果的差异、.结果:全部224例拔牙病例PDL麻醉总有效率达到83.48%。上颌拔牙的PDL麻醉有效率89.47%,下颌拔牙的PDL麻醉有效率82.26%.统计学χ2检验(χ2=1.2627,P〉O.25)显示两者PDL麻醉有效率差异无显著意义.炎症拔牙的PDI.麻醉有效率76.92%,非炎症拔牙的PDI.有效率84.91%,统计学χ2检验(χ2=1.0847,P〉0.25)显示两者PDL麻醉有效率差异无显著意义。结论:以无痛麻醉注射仪实施PDL麻醉拔牙,可以取得良好的麻醉效果,具有一定的可行性。但是具体操作时,在注射技巧方面需要加以改进提高,以克服由于病患牙痛变导致的非理想性注射条件而所造成的麻醉不全.
