Objective:Through psychological test, projection test, behavior grading test, three ways about children’s dental fear will observe whether the assessment methods of psychological intervention can affect the child dental fear, and compare the fully psychological intervention and the partly psychological intervention on the children’s teeth Section phobia treatment, then get the different effects about it.Methods:180 patients with 5-6 year-old standard untreated caries in deciduous molars of children as experimental subjects were randomly divided into three groups, A group, B group, C group,60 patients in each group, all patients were routinely Molars clinics tamponade. A group was given full psychological intervention (before treatment, during and after treatment); B group given only in the treatment of psychological intervention; C group had no psychological intervention. Before treatment, psychological interventions, including:children’s waiting room, doctor-patient communication, audio-visual education, children’s music background; the treatment of psychological intervention, including:children’s treatment room, tell-show-do measures to guide the imagination, encourage education, the use of role models, the independent treatment Etc.; treatment of psychological intervention, including:children room, in recognition of hugs, good on his word, oral health education. Also assessed using the following three methods of psychological intervention on the treatment of dental fear in children affected:(1) psychological test: Comparison of three groups of children in the experimental TO (triage time), T1 (treatment start), T2 (treatment started 5 minutes), T3 (10 minutes after the start of treatment), TE (treatment end 5 minutes) at different time points blood pressure, pulse the difference between; (2) projective test:Comparison of three groups of children with the fear of self-assessment points Figure Value differences; (3) behavior grading: comparison of three groups of raters score between the behavior of children. All the data were analyzed using statistical package SPSS 13.0.Results:1、the physiological test method results:Three groups of children at the time of the physiological value of TO was no significant difference (P>0.05).When three groups of children in the physiological value of T1 when compared with higher TO, B group and C group increased more significantly, the three groups were significantly different (P<0.05). Pairwise comparison:A group and B group, A group and C group were significant differences (P<0.05), B group and C group no significant difference (P>0.05).Three groups of children at T2, T3 than during T1 when the physiological decline in value, B group decreased more significantly, the three groups were significantly different (P<0.05). Pairwise comparisons: C group and A group, C group and B group were significantly different between (P<0.05), A group and B group have no significant difference (P>0.05).Three groups of children in the TE values when the minimum value of the physiological, A group and B group values lower than the C group, but the three groups there was no significant difference (P>0.05).2、the projection results of the test method: A group, B group, C group were children with the fear of 15%,20%, 46.7%, three groups were significantly different (P<0.05).3、the behavior grading results:A group, B group, C group scores of children with behavior scores were significantly different (P<0.05).4、B group of patients given psychological intervention in the treatment of dental fear being lower than C group, while group A patients received full psychological intervention, dental fear than a sense of group B have declined.5、three kinds of assessment methods have shown that psychological interventions can effectively alleviate dental fear of children, consistency is good.Conclusion:1、the physical test, projective test, assessment of children’s behavior grading dental fear has good consistency, you can choose a practical method to assess children.2、in the course of dental treatment in children with psychological intervention can ease children’s dental fear.Treatment of children with dental visits before treatment, after treatment, the whole psychological intervention can further reduce a sense of children’s dental fear.
