两种去龋方法对儿童牙科焦虑状态影响的对比研究

Comparison of Two Methods of Removing Caries of Children's Dental Anxiety State

目的研究两种去龋方法治疗乳牙龋对儿童焦虑状态的影响。方法对患儿分次治疗两侧龋齿,采用化学机械去龋法的为实验组,采用传统的牙钻去龋法的为对照组。观察儿童治疗过程中焦虑状态。结果首次就诊时,去龋治疗前实验组与对照组患儿焦虑状态无明显差异,P=0.81;去龋过程中,对照组患儿较实验组焦虑,P=0.04(P<0.05);去龋结束及充填结束时,患儿状态无明显差异,P=0.64,P=0.67。第二次就诊时,治疗前实验组患儿较对照组轻松,P=0.04(P<0.05);去龋过程中,实验组患儿焦虑状态也较对照组轻,P=0.03(P<0.05);去龋结束及充填结束时,患儿状态无明显差异,P=0.37,P=0.29。结论化学机械去龋法能明显降低患儿的焦虑状态,尤其适用于儿童的龋齿治疗。

Objective To assess the anxiety of children under two methods of removing caries. Methods Children with caries were randomly divided into experimental group and control group. The experimental group used chemo- mechanical caries removal method,and the control group used conventional bur drill grinding method to caries. The anxiety states of children were observed during the treatment.Results During the first treatment,there was no significant difference between children in the experimental group and control group,P =0. 81. During removing caries,children in the control group were more anxiety than the experimental group,P = 0. 04（ P〈0. 05）. In the end of removing caries and filling,there was no significant difference,P = 0. 64,P = 0. 67. During the second treatment,before the treatment,children of the experimental group were more relaxed than the control group,P = 0. 04（ P〈0. 05）. During removing caries,anxiety state of children in the experimental group were lighter than the control group,P = 0. 03（ P〈0. 05）. In the end of removing caries and filling,there was no significant difference between the two groups,P = 0. 37,P = 0. 29. Conclusion Chemo- mechanical caries removal method can significantly reduce the anxiety of children,especially for the treatment of preschool children.
