인공 탈회된 법랑질 표면의 CPP-ACP와 nano-sized carbonated apatite 함유물질의 재광화효과 = CPP-ACP of artificially demineralized enamel surface and remineralization of material containing nano-sized carbonated apatite

다국어 초록 (Multilingual Abstract)

This study compared tooth`s remineralization using enamel surface artificially demineralized with 0.1M lactate and HCL solution using Vicker`s Hardness Number(VHN) to compare CPP-ACP and remineralization of nano-sized Carbonate Apatite`s initial caries. Using pH circulation models divided into 0% nano-CA, 5% nano-CA, 10% nano-CA, 10% CPP-ACP and D.W. they were treated for 5 minutes, three times a day for 14 days to get the following results. 1. There were no significant differences among the initial surface hardness of samples demineralized surface of front tooth in 5 groups, and all 5 groups` surface hardness reduced significantly after demineralization of enamel. 2. When inquiring into hardness changes through pH circulation model, the highest hardness change was in 5% nano-CA group. Also, 10% nano-CA and 10% CPP-ACP groups increased significantly, but there was no significant difference statistically. In generalizing the above experiment results, nano-sized Carbonate Apatite showed remineralization, and compared to 10% CPP-ACP group, 5% nano-CA had remineralization to artificial caries, thus implies that when we develop method to contact with tooth of nano-CA in the future, it is expected to gain synergy effect on function of saliva, a natural remineralization material.
