Effects of amorphous calcium phosphate containing sealant on demineralization at the enamel-sealant interface

Abstract

The objective of this study was to determine the effects of amorphous calcium phosphate (ACP) containing sealants on demineralization at the enamel/sealant interface Extracted third molars were randomly assigned into four groups (n = 10): 1st and 2nd groups were sealed with Aegis® (ACP containing sealant), 3rd and 4th groups were sealed with Delton® (non-ACP containing sealant). The control groups were immersed in deionized water for 4 days. The enamel mineral loss was evaluated by Vicker’s microhardness. The results showed that Aegis® sealed specimens were statistically significant different from Delton® sealed specimens (p=0.01).This study demonstrated that ACP containing sealant significantly decreased demineralization at the enamel/sealant interface.
