Title : Evaluation of tooth stains caused by coke and orange juice using pH-cycling
Abstract :

This in vitro study investigates if commercial coke (CK) and orange juice (OJ) can cause a tooth stain over 7 days of pH-cycling and whether quantitative light-induced fluorescence-digital (QLF-D) can evaluate a tooth stain. Ten bovine enamel specimens underwent a 7-day pH-cycling model, using CK, OJ, and a remineralizing solution. Before the daily pH-cycling, white-light and fluorescence images of the enamel surface were photographed with QLF-D to evaluate the changes in L*, a*, b* values, color change (ΔE), mean fluorescence loss (ΔF, %), maximum fluorescence loss (∆FMax, %) compared to those at baseline. While the CK group showed significant differences in ∆E, ∆F, and ∆FMax over 7 days of the pH-cycling, the OJ group showed no significant differences. As the days progressed, the teeth L*, a*, b* in both groups tended to become similar to the L*, a*, b* in the drink itself. Significant correlations were found between ∆E, ∆F, and ∆FMax when the correlation analysis was performed excluding missing values for each pair (p<0.05). While OJ did not show a significant difference in ∆E, ∆F, and ∆FMax during the pH-cycling, the CK caused a significant tooth stain. Further, QLF-D can be used as a supplementary tool in checking a tooth stain
