Abstract:
Objective To observe effects of rhubarb extract on Ca dissolved quantity in demineralized enmnel. Methods Demineralization was performed after treating tooth facing with rhubarb extract of different concentrations and deionized water. The concentration of Ca was detected by ASCA biochemical analyzer after demineralization. Results Dissolved quantity of demineralized Ca in the rhubarb extract group (2 mg/ml, 4mg/ml) was significantly lower than that of the deionized water group (P<0.01) and the rhubarb extract group (1 mg/ml) (P<0.05), but higher than that of 2% sodium fluoride group (P>0.05). Dissolved quantity of demineralized Ca in the rhubarb extract (1 mg/ml) group was significantly higher thanthat of 2% sodium fluoride group (P<0.01), but lower than that of the deionized water group(P>0.05).Conclusion The rhubarb exwact (2mg/ml, 4mg/ml) can inhibit Ca dissolution in demineralized enamel.The inidal effective concentration of rhubarb extract is 2 mg/ml.
