The Effect of Different Application Techniques of Epigallocatechin Gallate on Some Properties of an Etch and Rinse Adhesive

Abstract

Our study aimed to investigate the effect of EGCG different application techniques on the bond strength of dental adhesive to dentin under different aging methodologies. An etch and rinse dental adhesive was used. Also, the dental adhesive degree of conversion was analysed after EGCG application. According to literature, a Matrix metalloproteinases activity was detected after the etching step of etch and rinse dental adhesives. Matrix metalloproteinases were reported to have a collagen degradation ability which would adversely affect the bond strength to dentin. EGCG is one of the natural flavonoids that are reported to have a favourable effect on the dental adhesive bond strength to dentin. This was suggested to be achieved through collagen cross-linking and matrix metalloproteinases inhibitory effect of EGCG.
