Acid resistance of human dentin after riboflavin/ultraviolet light (RF/UVA) treatment. (A) Preparation of root dentin specimens. (B) Micro-computed tomography profiles of dentin in control (a) and RF/UVA (b) groups before and after pH-cycling. (C–F) Mineral loss (C,E) and lesion depth (D,F) of demineralized dentin. (C,D) Show the results after treatment with a demineralizing cycling (pH 4.5 for 2 min, interval of 3 min, pH 6.8 for 60 min, 6 cycles per day), while (D,E) show the results after remineralizing cycling (pH 4.5 for 2 min, pH 6.8 for 30 min, 3 cycles per day). *Statistically significant differences were detected between the groups. (Student’s t-test, P < 0.05, n = 7)
