Abstract:
Objective To investigate the remineralization effects of the Aominqing dental desensitizer and the fluoride dentifrice on the demineralized enamels. Methods Sixty-three teeth were randomly divided into three groups after demineralization , then was remineralized for eight days by using Aominqing dental desensitizer, fluoride dentifrice (1.1 g/L), and deionized water, respectively. The thin sections of teeth were analyzed under the con-focal laser scanning microscope (CLSM). The morphology of the surface of teeth was observed under the scanning electron microscope (SEM). Results Under CLSM, the evaluation parameter area of the fluorescent lesion (A,μm2) processed by Aominqing and by fluoride was (3.19 ± 0.19) × 104, (3.61 ± 0.26) × 104 μm2, respectively. The total fluorescence (TF) was (0.61 ± 0.09) × 106, (0.89 ± 0.15) × 106, average fluorescent of the lesion(AF) was (18.98 ± 1.56), (24.65 ± 2.39), and the above parameters were all less than those in the blank control group [A=(4.89 ± 0.24) × 104 μm2,TF=(1.78 ± 0.21) × 106, AF = 36.29 ± 2.57] (P < 0.01). The evaluation parameters in the Aominqing group were less than those in the fluoride dentifrice group(P < 0.05). Under SEM, the surface of the group processed by Aominqing was the smoothest, compared to the fluoride dentifrice group and the blank control group. Conclusions Both Aominqing dental desensitizer and fluoride dentifrice (1.1 g/L) have the remineralization effects on the demineralized enamels, and the former has a stronger effect.
