作者检查小儿糖负荷(用10%蔗糖含漱1分钟)前、后唾液结晶图的变化,研究防龋药物对唾液抗龋力和结晶图的影响,检查10岁～12岁小儿66例,其中给防龋药物51例:乳清酸钾内服12例,0.25g1日3次,10天1疗程,24月间隔6月。甘油磷酸钙内服9例,剂量疗程同上。0.2%氟化钠含漱10例,1日1次,期限同上。氟溶液(1mg/L)含漱10例.氟内服10例,1 mg 10天1次共6月。不给防龋药物15例(对照组):无龋齿8例,有龋齿7例。唾液结晶图检查方法,用吸管取混合唾液滴在载玻片上,放在37℃恒温器内1小时,然后用放大6倍显微镜观察干了的唾液滴的微小结晶图.研究结果糖负荷以前,可看到Ⅰ型和Ⅱ型唾液结晶图,Ⅰ型最多,呈树枝状。Ⅱ型为规则的细丝状几何图形,是唾液抗龋力较低的结晶图,因为多见于对照组有龋齿者。糖负荷以后,唾液结晶图发生变化,出现Ⅲ、Ⅳ、
The authors examined changes in the saliva crystallograms of children before and after infusing sugar (1 minute with 10% sucrose) to study the effect of anti-caries medication on saliva anti-cariogenicity and crystallization patterns. Sixty-six children aged 10-12 years To anti-caries drugs in 51 cases: 12 cases of ovalbuminate orotate, 0.25g1 3 times, 10 days a course of treatment, 24 months interval in June. 9 cases of glycerol calcium phosphate orally, the same dose treatment. 0.2% sodium fluoride gargle in 10 cases, 1 on the 1st, the deadline Ibid. Fluoride solution (1mg / L) gargle in 10. Fluoro-oral administration of 10 cases, 1 mg 10 days a total of 6 months. Do not give anti-caries drugs in 15 cases (control group): 8 cases without caries, caries in 7 cases. Saliva crystallization test method, the mixture of saliva with a straw drop on a slide, placed in a 37 ° C thermostat for 1 hour, and then observed with a magnification of 6 times microscopic micrograph of dried saliva droplets crystallization results before the sugar load, You can see the type Ⅰ and type Ⅱ saliva crystallography, type Ⅰ up, was dendritic. Type II is a regular, filamentous geometry that is a salivary anti-cariogenic crystalline map that is more common in patients with caries in the control group. Sugar load, the saliva crystallography changes, there Ⅲ, Ⅳ,
