Abstract This in vitro study evaluated the effects of adding chitosan (Chi) to desensitizing agents applied before dental bleaching on enamel properties. Bovine enamel specimens were allocated to seven groups (n = 12): no treatment (negative control), 2% NaF (positive control), 2% NaF + 2% Chi, 2% NaF + 5% Chi, 2% NaF + 5% KNO3, 2% NaF + 5% KNO3 + 2 ...
