Abstract
|
|
|
The object of this study was to investigate caries preventive effect of chewing gum containing xylitol, funoran, calcium hydrogen phosphate and casein phosphopeptide´ by examining Vickers´ hardness and surface roughness with confocal laser microscope.
Early caries-like lesions were created using 0.1 M-lactic acid sodium hydroxide buffer(pH 4.0). 8 pieces of 3-mm diameter bovine enamel specimen with early caries-like lesions were mounted into the recesses of lingual surface of the acrylic mandibular removable appliance. 13 subjects were the appliance for. daytime and chewed control and experimental gums 7 times in a day, for 3 days. In order to evaluate the remineralization effect of chewing gum on specimens, we measured Vickers´ hardness number after chewing gum, I day, 2 days, 3 days after and calculated surface roughness immediately after chewing gum.
Vickers´ hardness number of experimental chewing gum was significantly higher than control in 2 and 3 days after. Surface roughness of experimental chewing gum was significantly lower than control immediately after chewing gum.
These results showed that experimental gum has more effective in remineralization of bovine tooth enamel, and it is more effective at immediately after chewing.
