Effects of Xylitol on Remineralization of Artificial Demineralized Enamel

Abstract

: This is a morphological investigation of the influence of xylitol on remineralization in experimen tally demineralized dental enamel . Materials were human third molars , the dental surfaces of which had been demineralized. The samples were immersed at 37℃ for 2, 4, and 8 weeks in either a remineralizing solution (Ca: 1mM, P: 2mM, F: 0.2PPm) containing 10% xylitol or a remineralizing solution without xylitol . Specimens were then prepared as ground sections (100μm) and contact-microradiograms were obtained . Degrees of mineralization were measured by Multipurpose Image Processor . Results showed that, in the no-xylitol group, remineralization had occurred in the surface layer but not in the intermediate and deep layers.
