Objective: to study whether etchant solution containing fluoride could reduce the negative impact of granting etching.
Methods: As many as 40 samples of teeth that have been etched for 30 seconds and then measured the surface roughness (by using the profilometer stylus). After placed in artificial saliva fluid for 7 days teeth are measured using profilometer. Twenty buccal surfaces of premolar teeth were prepared for study. The buccal surfaces were etched using 37% phosphoric acid etchant and 37% phosphoric acid etchant with 1,23% APF gel.
Results: Using the two-way variance analysis test (Anova) and HSD Tuckey multiple comparison, a significant difference in Ra value between the group etched by fluoride-containing etchant and the group etched by nonfluoride-containing etchant, and in remineralization process between the group etched by fluoride-containing etchant and the group etched by nonfluoride-containing etchant (p<0,05). Analysis using Rz value between the group etched by fluoride-containing etchant and the group etched by nonfluoride-containing etchant, yet a significant difference in remineralization between both group.
Conclusions: The are was statistically significant differences between etched enamel surface using fluoride-containng etchants and nonfluoride-containing etchants and also statistically significant difference in both groups after the enamel surface remineralization
