“…However, fluoride is not a food additive so it cannot be directly added to it. There are only few foods that contain large amounts of F 14) but in our previous study 15) , calcified seaweed contains large amounts of Ca, P and F, which may be effective in remineralization process.…”

The incidence of root caries and hyperesthesia in elderly people tend to increase with increasing age. This can be prevented by enhancing the root surfaces against aciduric bacteria. In order to prevent root caries, a chewing gum containing calcified seaweed rich in Ca, Mg, Na, F and P was created. A dentin block was made from the cervical part of the third molar after removing the cementum. The dentin blocks were immersed in remineralizing solution with extract of the gum with or without calcified seaweed for 2 weeks. The dentin blocks were immersed in demineralizing solution for 6 hours and acid resistance was evaluated after. Demineralization was evaluated by CMR image, demineralization depth (Ld) and mineral loss quantity ( Z) by image analysis, qualitative analysis by EPMA and the surface structure with the SEM. CMR image analysis revealed that the region immersed in aciduric solution had less quantity of demineralization than the region which was not immersed. A significant difference in Ld and Z of the demineralization area after the aciduric treatment between the solution with calcified seaweed and the solution without aciduric treatment (p<0.05) was observed. Levels of Ca, P and Mg were detected in EPMA except for F. In SEM, the dentinal tubules of the demineralized region without aciduric treatment was enlarged which was not seen in demineralized region after aciduric treatment. The results indicate that the chewing gum with calcified seaweed is effective in increasing dentinal acid resistance.Journal of Hard Tissue Biology 20[2] (2011) p87-92

Calcified seaweed contains abundant quantities of calcium, magnesium, phosphate, sodium and fluorine ions. The objective of this study was to investigate the effect of chewing gum containing calcified seaweed on the remineralization and aciduric properties of enamel. For intraoral experiments, enamel blocks prepared from third molars were attached to an appliance. Each block was covered with acid-resistant nail varnish, except for a window measuring 6 x 4 mm. A caries-like lesion was artificially prepared in the window. Participants attached the appliance and chewed gum for 20 min, 4 times a day. The intraoral experiment period was 2 weeks. Half of each window was re-covered with nail varnish. In the aciduric experiment, these blocks were immersed in demineralizing solution. After demineralization, the blocks were embedded in polyester resin and prepared in ground sections. Contact microradiograms of these ground sections were obtained. A high degree of remineralization occurred at the surface and at a deep layer in the remineralized enamel area. In the aciduric experiment area, further demineralization was observed beneath the original demineralized layer, and overall depth of demineralization increased. A thin, highly mineralized layer was observed between the two demineralized layers. The degree of remineralization and aciduric rate with calcified seaweed treatment was higher than that with non-calcified seaweed treatment (p<0.05). These results suggest that chewing calcified seaweed-containing gum significantly enhances the remineralization and acid resistance of enamel by exposure to fluorine ions.
