The aims of this study were to investigate the efficacy of CPP-ACP containing Tooth Mousse on the remineralization of enamel lesions and to compare its efficacy to that of a fluoride-containing toothpaste.
Permanent teeth were placed in demineralizing solution for 96 hours to produce artificial caries-like lesions 120-200 microm in depth. They were sectioned into 100-150 microm thick samples and randomly assigned to five groups: for Group A, a fluoridated toothpaste (1100 ppm) was used as a positive control and in Group B, a non-fluoridated toothpaste was used as a negative control. Tooth Mousse containing CPP-ACP was tested by three different means: as a toothpaste (Group C); as a topical coating (Group D); and (Group E) as a topical coating after treating the sections with the same fluoridated toothpaste as in Group A.
The lesion depth decreased significantly by 7 per cent in Group A, 10.1 per cent in Groups C and D, and 13.1 per cent in Group E (Paired t- test, p < 0.05), while in Group B the lesion depth increased significantly by 23 per cent.
Based on the data obtained, CPP-ACP containing Tooth Mousse remineralized initial enamel lesions and it showed a higher remineralizing potential when applied as a topical coating after the use of a fluoridated toothpaste.
本研究旨在调查含酪蛋白磷酸肽 - 无定形磷酸钙(CPP - ACP)的护齿泡沫对牙釉质病变再矿化的效果,并将其效果与含氟牙膏进行比较。
将恒牙置于脱矿溶液中96小时,以产生深度为120 - 200微米的人工龋样病变。将它们切成100 - 150微米厚的样本,并随机分为五组:A组使用含氟牙膏(1100 ppm)作为阳性对照,B组使用不含氟牙膏作为阴性对照。含CPP - ACP的护齿泡沫通过三种不同方式进行测试:作为牙膏(C组);作为局部涂层(D组);以及(E组)在使用与A组相同的含氟牙膏处理切片后作为局部涂层。
A组病变深度显著降低了7%,C组和D组降低了10.1%,E组降低了13.1%(配对t检验,p < 0.05),而B组病变深度显著增加了23%。
根据获得的数据,含CPP - ACP的护齿泡沫使初期牙釉质病变再矿化,并且在使用含氟牙膏后作为局部涂层应用时显示出更高的再矿化潜力。
