Abstract
Objectives :The purpose of this study was to investigate the remineralization effect of bamboo salt containing dentifrice on incipient dental caries lesions using confocal laser scanning microscope by the chemical pH cycling model.
Methods :Specimens of bovine tooth enamel were embedded in resin, polished, exposed to a lactate carbopol buffer system for 44 hours, and divided into 3 groups: (1)control, (2)containing SMFP(0.76% and bamboo salt 2.0% with DCPD abrasive formula), and (3)containing NaF(0.22% and bamboo salt 3.0% with a silica abrasive formula). Each group contained 12 specimens. Surface hardness was compared before and after application of the chemical pH cycling sequences for 20 days. A confocal laser scanning microscope(CLSM) was used for evaluation of remineralization on subsurfaces of enamel lesions.
Results :Remineralization of bamboo salt dentifrice with NaF, silica and bamboo salt 3% was significantly greater than those for the SMFP, DCPD and bamboo salt 2% groups as indicated by surface hardness (p<0.05). Dentifrice with NaF, silica and bamboo salt 3% decreased the fluorescent lesion depth compared to the other groups by CLSM.
Conclusion :Dentifrice with NaF, silica and bamboo salt 3% could be a useful preventive agent against incipient dental caries.
