根管治疗患者牙科恐惧症的调查分析

Investigation of dental anxiety on root canal treatment

目的探讨减轻根管治疗中牙科恐惧(DA)的方法。方法将360名牙髓炎患者分为三组,每组120名。A组患者为口头与书面告知根管治疗内容,B组患者书面告知同时进行心理沟通,C组患者进行书面告知、心理沟通并辅以必兰局部麻醉。采用改良牙科焦虑量表(MDAS)测量三组患者不同治疗时期DA水平的变化,并用视觉模拟量表(VAS)评估三组患者对根管预备的恐惧程度,对根管治疗前后测量数据进行统计学分析。结果随着就诊次数的增加,三组患者的DA值均逐渐下降,其中以C组下降最为明显,其次为B组。同一组内治疗前后DA值均有显著性差异(P<0.01)。三组患者根管预备前的DA值及VAS评估结果也具有显著性差异(P<0.05)。结论心理沟通与麻醉同时应用可显著降低根管治疗中的牙科恐惧。

Objective To study the method of decreasing dental anxiety （DA） on root canal treatment. Methods 360 patients were divided into group A, group B and group C. Parol and written not/ce about the content of root canal treatment were given to the patients of group A, written notice and psychological communication to group B, written notice, psychological communication and local anesthesia to group C. The change of DA level were measured in patients of three groups during treatment period. The patient＇s fear degree were evaluated by means of visual analogue scale （VAS）. The data before and after root canal treatment were analyzed. Results The level of DA decreased along with the increasing of treatment frequency. The decreasing of group C was most obviously, next to group B. There were statistical difference before and after root canal preparation in the DA of same group（P〈0.01）. There were statistical difference in DA and VAS among group A, B and C （P〈0.05）. Conclusion Psychological communication and anesthesia can obviously decrease dental anxiety level on root canal treatment.
