| Research Abstract |
In order to exchange conventional dental practice focusing operative treatments into clinical system for dental health beased on findings in cariology research, this study investigated the practical sterategy from viewpoint of (1) early caries detection, (2) caries risk evolution technology, and (3) materials for enhancement of remineralization.
(1) Early detection of dental caries
Electrical caries monitor (ECM) was found to be sensitive and useful enough to detect dematerialized enamel lesions with ld of about 100 μm.
(2) Risk assessment
It was confirmed that caries risk tests newly developed in a medical laboratory is highly useful for individual health care and also for school-based mass screening of high-risk children.
(3) Materials for remineralization enhancement
It was concluded that fluoride slow releasing materials, especially a glass ionomer cement is the most useful material to limit deminaralization and to increase remineralization of surrounding enamel and dentine. In addition, it was found that potato starch induced phosphoryl-oligosaccharides (POs) enhances reminaralization by improving salivary mineral status, and that can be applied as a dietary ingredient.
