化学-机械与传统车针祛腐法在乳牙活髓保存治疗中的对比研究

目的对比研究化学-机械祛腐法与传统车针祛腐法对深龋近髓乳磨牙治疗后活髓保存率的差异。方法选择就诊于解放军总医院儿童牙病科的192例患儿的192对深龋近髓的乳磨牙,每对乳磨牙随机分为化学-机械祛腐法和传统车针祛腐法两组,去除腐质后,护髓剂Ca(OH)2间接盖髓,含氟玻璃离子水门汀一次性填充,术后1个月~1年内门诊随诊。结果化学-机械祛腐法祛龋活髓保存成功率95.3%;传统车针祛腐法祛龋活髓保存成功率87.0%,二者有显著性差异。结论化学-机械祛腐法在深龋近髓乳磨牙治疗的治疗中可以更大程度地保存活髓,从而减少对后继恒牙发育的影响。

Evaluation of chemomechanical and traditional mechanical caries removal in indirect pulp capping of symmetric primary molars

Objective To evaluate the difference between chemomechanical and traditional mechanical caries removal in indirect pulp capping of the symmetric primary molars.Methods A total of 192 children with deep caries in the two symmetric primary molars were studied.The two symmetric primary molars were divided into two groups for treatment with chemomechanical method with CarisolvTM system or traditional mechanical method.After caries removal,calcium hydroxide agent was placed as the protective base,and glass ionom...
