“…With excess moisture, dentin adhesives will undergo phase separation or lead to limited polymerization in the interface . If the etched surface is too dry, the demineralized soft collagen matrix may collapse to a membrane hampering adhesive’s infiltration. , Matrix metalloproteinase (MMPs) is another factor that affects dentin bonding’s lifespan, which is prone to be activated by water and degrades denuded collagen fibers at the bottom of the hybrid layer, forming a weak zone. , Much effort is dedicated to solving these problems, such as chlorhexidine, carbodiimide, , polyphenol derivatives, and biomimetic remineralization have been used to resist collagen degradation or directly inhibit endogenous collagenolytic activity. − However, these methods cannot deal with the essential problem that dentin collagen fibers remain exposed during the etching process.…”
