心理干预加无痛麻醉对降低去髓术患者牙科焦虑症的疗效观察

目的:探讨减轻慢性牙髓炎患者去髓术治疗过程中牙科焦虑症(Dental anxiety,DA)的方法。方法:200例慢性牙髓炎患者,书面告知去髓术方法,疗效以及可能出现的并发症等后,随机分为4组。A组:在碧兰麻醉下行去髓术;B组:无痛麻醉(Single tooth anesthesia,STA)下行去髓术;C组:进行心理干预后在碧兰麻醉下行去髓术;D组:心理干预后在STA无痛麻醉下行去髓术。采用改良牙科焦虑量表(Modified dentalanxiety scale,MDAS)测量4组患者不同治疗时期DA水平的变化,并对去髓术治疗前后测量数据进行统计学分析。结果:复诊时4组患者的DA值均呈下降趋势,其中以D组下降最为明显,其次为B、C组。同一组内治疗前后DA值均有显著性差异(P<0.05)。结论:心理干预与STA无痛麻醉同时应用可显著降低去髓术治疗中的牙科恐惧。

Effect of psychological intervention and single tooth anesthesia on the dental anxiety of patient with pulpectomy treatment

AIM: To explore the method of decreasing dental anxiety(DA) on pulpectomy.METHODS: Two hundred patients with chronic pulpitis were given written notice about the method,effects and complications of pulpectomy.They were then randomly divided into 4 groups.Patients in each group received pulpectomy under anesthesia(group A),under single tooth anesthesia(STA)(group B),psychological intervention plus anesthesia(group C) and psychological intervention plus STA(group D) respectively.Modified dental anxiety scale(MDAS) was used to measure the DA levels before and after pulpectomy.RESULTS: DA levels decreased in all four groups.Group D showed the most decrease,followed by group B,C and A(P<0.05).CONCLUSION: Psychological intervention plus single tooth anesthesia can significantly decrease dental anxiety during pulpectomy.
