The cross-section of lesions on the enamel surface in the artificial caries models. (a–f) MicroCT graphs ( × 50) of the demineralization cross-sections in C8-P-113 (MBC), DPS-C8-P-113 (MBC), 8DSS-C8-P-113 (MBC), 8DSS-C8-P-113 (16 μM mL−1), agarose, and control group. (g) Lesion depth on enamel surfaces. (h) Mineral density of lesion on enamel surfaces. ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001, compared with control group.
