Abstract
The purpose of this study was to investigate the effect on carious dentin after topical application of 10% (NH4)2MoO2F4. The following results were obtained.
Firstly, CaF2 formation was found with X-ray microbeam diffraction on the surfaces of both acute (active) and chronic (arrested) caries after the application. In addition, the CaF2 formation was identified through SEM observation.
Secondly, both molybdenum and fluoride had deeply infiltrated into carious lesion, especially in cases of acute caries. These results suggest that one of (NH4)2MoO2F4's caries restraining effects is due to CaF2 formation and infiltration of molybdenum and fluoride into the carious lesion.
