When enamel alone is etched and is to be bonded with a hydrophobic resin (e.g., bisphenol-A glycidyl dimethacrylate [ bis -GMA]–based resin), it must be dried completely with warm air until it takes on a white, frosted appearance. Dentin, in contrast, cannot withstand such aggressive drying, which would cause bond failure because of the formation of impermeable, collapsed collagen fibers. 酸蝕後，牙本質要用氣槍吹到表面有光澤但無明顯水分，因為太乾燥的話會使得collagen fiber呈現倒下攤平的現象，不利於後續bonding步驟的溶劑進入。
