To evaluate the effects of three caries removal methods on children's dental fear by physiological measure.
90 children with caries lesions into dentin in primary molars were divided into three groups randomly: Chemomechanical carious removal group, atraumatic restorative treatment (ART) groups and traditional rotary instrument group. The baseline of blood pressure, pulse was recorded before the treatment. Then the blood pressure and the pulse of each subjects were measured 5, 10 and 15 minutes and at the end of the treatment respectively. The dental fear was evaluated by observing the trend of blood pressure and pulse in the process of the treatment, and the results were analyzed by SPSS11.5 software package, using one-way ANOVA and Student-Newman-Keuls methods to determine the effects of different caries removal methods on children's dental fear.
The degree of dental fear in traditional drilling group was significantly higher than that in chemo-mechanical group and ART group. The difference of each index between rotary instrument group and ART group was significant at the first time-point from the beginning of the treatment (P<0.05), but not significantly between rotary group and chemo-mechanical group (P>0.05), and between ART and chemo-mechanical group. (P>0.05). At the second time-point, the difference of systolic blood pressure was significant between rotary group and chemomechanical group(P<0.05), and the same between rotary group and ART group (P<0.05), but not between ART and chemo-mechanical group (P>0.05), while the difference of the other index among the three groups was not significant(P>0.05). There was no significantly difference of each index among the three groups at the time-point afterwards(P>0.05).
Compared to traditional caries removal method, chemomechanical technique and ART may decrease children's dental fear effectively.
通过生理指标评估三种龋病去除方法对儿童牙科恐惧的影响。
将90例乳牙龋损累及牙本质的儿童随机分为三组：化学机械去龋组、非创伤性修复治疗（ART）组和传统旋转器械组。治疗前记录血压、脉搏基线。然后分别在治疗后5分钟、10分钟、15分钟及治疗结束时测量各受试者的血压和脉搏。通过观察治疗过程中血压和脉搏的变化趋势评估牙科恐惧，结果采用SPSS11.5软件包进行分析，运用单因素方差分析和Student-Newman-Keuls法确定不同龋病去除方法对儿童牙科恐惧的影响。
传统钻牙组的牙科恐惧程度显著高于化学机械组和ART组。治疗开始后的第一个时间点，旋转器械组与ART组各指标差异有统计学意义（P<0.05），但旋转器械组与化学机械组之间差异无统计学意义（P>0.05），ART组与化学机械组之间差异也无统计学意义（P>0.05）。在第二个时间点，旋转器械组与化学机械组收缩压差异有统计学意义（P<0.05），旋转器械组与ART组收缩压差异也有统计学意义（P<0.05），但ART组与化学机械组之间差异无统计学意义（P>0.05），而三组间其他指标差异无统计学意义（P>0.05）。此后各时间点三组间各指标差异均无统计学意义（P>0.05）。
与传统龋病去除方法相比，化学机械技术和ART可有效降低儿童的牙科恐惧。
