在口腔局部使用氯化镧、氟化钠,观察防龋效果中,检测了部份唾液内含物和牙菌斑,发现镧和氟都能提高唾液SIgA和淀粉酶的含量;氯化镧的抑菌谱宽于氟化钠;氯化镧的毒性小,用药安全范围大。 材料和方法 一、唾液生化检测:按双盲法在幼儿园六个涂料组抽20人,在中、小学六个胶姆糖组抽30人,于给药前一周,用药中期(第二个月)各采空腹唾液10毫升送检;①用单向琼脂扩散法检测SIgA、IgG;②淀粉酶;③
In the oral use of lanthanum chloride, sodium fluoride in the oral cavity to observe the anticaries effect, some saliva contents and plaque were detected. It was found that both lanthanum and fluorine could increase the contents of SIgA and amylase in saliva; Antifungal spectrum wider than sodium fluoride; lanthanum chloride toxicity, medication safety range. Materials and methods First, the saliva biochemical tests: According to double-blind method in kindergarten six paint group pumping 20 people, in the primary and secondary six gum group pumping 30 people, in the week before medication, medication in the middle (the second month ) Were taken fasting saliva 10 ml submission; ① unidirectional agar diffusion assay SIgA, IgG; ② amylase; ③
