为提高防龋效果,需确定个体防龋适应症,判断牙齿易患龋病的素质,包括评定卫生指数,测定乳杆菌值,混合唾液的性质,釉质的抗酸性等。作者利用釉质抵抗力试验(T(?)P)——根据用规定剂量的酸腐蚀后釉质的染色强度,评定釉质的抗酸性。对釉质抗酸性指标较低的小学生,集中采取积极的防龋措施,即选择性防龋法,已获得明显效果。
In order to improve the effect of caries prevention, it is necessary to determine individual anti-caries indications and to judge the quality of teeth susceptible to caries, including the assessment of hygienic index, determination of lactobacilli, mixed saliva, and acid resistance of enamel. The authors used the enamel resistance test (T (?) P) - to evaluate the acid resistance of enamel based on the staining intensity of the enamel after acid etching with the prescribed dose. For enrolled pupils with low enamel anti-acidity index, they adopted a positive measure of anti-caries, that is, the selective caries control method, and achieved significant results.
