心理干预对儿童牙科畏惧症治疗的影响

目的通过生理测试法观察有无心理干预对儿童牙科畏惧症的影响。方法选取90例6~7岁符合标准的乳磨牙中龋初诊患儿为实验对象,随机分为A、B两组,每组45例,所有患儿均进行常规龋洞充填术。A组给予心理干预,B组无心理干预。分别在T0（分诊时）、T1（治疗开始时）、T2（治疗开始后5 min）、T3（治疗结束5 min）不同时间点测患儿的血压、脉搏。结果二组患儿在T0时的各项生理值比较差异无统计学意义（P〉0.05）;二组患儿在T1时生理值均较T0时升高,B组升高较A组更为明显,两组比较差异有统计学意义（P〈0.05）;二组患儿在T2时生理值均较T1时有所下降,A组下降较为明显,两组比较差异有统计学意义（P〈0.05）;二组患儿在T3时的生理值均降至最低值,两组比较差异无统计学意义（P〉0.05）。结论在患儿牙科诊疗过程中进行心理干预可缓解儿童牙科畏惧症。

Effect of Psvchological Intervention on the Treatment of Children's Dental Fear

Objective To observe the impact of psychological intervention in the treatment of children’s dental fear through physiological test method. Methods Ninety children aged from 6 to 7 year with standard untreated caries in deciduous molars were selected as experimental subjects.They were randomly divided into group A and group B(each n=45).All the children were received routine dental caries plombage.Group A was given psychological intervention,while group B had no psychological intervention.Blood pressure and pulse of the children were tested in the different time points,including T0(triage time),T1(treatment start-time),T2(5 minutes after treatment start),and T3(5 minutes after treatment end). Results The physiological values at T0 in children of two groups showed no statistically significant difference(P>0.05).The physiological values at T1 were all higher than those at T0 in children of two groups,group B was significantly increased than group A,and the difference was statistically significant between the two groups(P<0.05).The physiological values at T2 were lower than those at T1 in children of two groups,group A decreased more significantly,and the difference was statistically significant between the two groups(P<0.05).The physiological values at T3 in children of two groups were minimum,and no statistically significant difference was found between the two groups(P>0.05). Conclusions Physiological intervention in the course of dental treatment can ease children’s dental fear.
