摘要
OBJECTIVE:To investigate the effect of Galla Chinensis with or without fluoride on demineralization of enamel.
METHODS:Galla Chinensis with or without fluoride and acid buffer were used to treat the samples alternately and the treatment was repeated 8 times. Then the calcium of acid buffer was measured by American PE HTS 7000 plus and the specimens were observed with laser scanning confocal microscope.
RESULTS:Compared with the calcium concentration of control group (deionized water or fluoride), the calcium concentration of all tested groups (except the 1 mg/ml group without fluoride) decreased significantly (P < 0.25). There was marked difference in total fluorescence (TF) and average fluorescence (AF) between the tested groups and control group (P < 0.05). As for the area of lesion, only groups without fluoride and the 4 mg/ml group containing fluoride decreased (P < 0.01). Confocal images showed that the zone of red area of tested groups was narrower than that of control group.
CONCLUSION:Galla Chinensis can reinforce the resistance of enamel to acid, either with or without fluoride.
