【摘要】 目的评价非创伤性填充技术(ART)用于治疗儿童乳磨牙龋损的效果和可行性。方法分别采用ART与传统银汞合金修复技术修复3~4岁患儿乳磨牙共354颗,其中ART组180颗,银汞合金组174颗,治疗中采用行为分级法,对患儿在治疗中行为表现进行评估,并于术后1年复查修复体。结果ART组1年成功率为83.33%,银汞合金组成功率为85.06%,经χ2检验,差异无统计学意义。银汞合金组的继发龋发生率高于ART组,差异有统计学意义。ART组行为分级达Ⅲ、Ⅳ度的儿童有70%,而银汞合金组只有20.58%,差异有统计学意义。结论ART是一种简便可行有效的治疗技术,尤其适用于患儿初次作龋损的修复治疗。更多还原

【Abstract】 Objective To evaluate the effect and the feasibility of the ART(Atraumatic Restorative Treatment) restoration in the cavities of young children’s deciduous molars.Methods The ART and conventional amalgam were used to restore the young children’s(from 3 to 4 years old) deciduous molars,and there were 180 in the ART group and 174 in the amalgam group.The children’s behavior in the treatment was evaluated by the Frankl’s method.And the restorative effect was examined after one year.Results The success ratio of the ART group was 83.33%,and the amalgam group was 85.06%.There was no statistically significant difference by χ~2 text.But in the behavior classification,the ART group had 70% in grades Ⅲ or Ⅳ,and the amalgam had 20.58%.The difference was statistically significant.The occurence rate of secondary caries was higher in amalgam group than in the ART group.Conclusion ART was a kind of easy and feasible method,especially for the young children.更多还原
