为了阐明人类牙髓对FC反应的因素,作者在标准化的实验条件下用组织学及酶组织化学的方法研究了人类牙髓对FC及其主要成份甲醛和甲酚的短期反应。材料和方法:在58个9—15岁儿童因正牙需拔除的健康下颌前磨牙上完成了实验。受试液为:①、新鲜制备的4%和19%甲醛液(缓冲至pH7);②、35%甲酚溶于60%甘油和5%蒸馏水中;③、FC液(布克表氏方);④、丁香油酚。在局麻下作断髓 In order to elucidate the human dental pulp reaction to FC factors, the authors studied the short-term reaction of human dental pulp to FC and its major components formaldehyde and cresol by histochemical and enzymatic histochemistry under standardized experimental conditions. Materials and Methods: Experiments were performed on 58 healthy children aged 9-15 years with mandibular premolar mandibular exclu- sions. The test solution was: ① freshly prepared 4% and 19% formaldehyde solution (buffered to pH7); ② 35% cresol dissolved in 60% glycerol and 5% distilled water; ③ FC fluid ); ④, eugenol.
