| Research Abstract |
The aim of this study is to compare mineral level evaluation with crystal structure analysis of demineralized and remineralized enamel. The specimens were prepared with powdered enamel enclosed by membrane filter. The specimens evaluated mineral loss by CMR and analyzed crystal structure by FTIR and TEM. The results of this study, when there was no significant difference by CMR evaluation, the crystal structure of remineralized enamel and sound enamel was different. The method of this study which was compared mineral level evaluation with crystal structure analysis was appropriate for keeping 4 weeks remineralization time. It was concluded that it is important for evaluate of demineralization and remieralization of enamel, not only use mineral level evaluation but also crystal structure analysis.
