氢氧化钙用于深龋治疗时,可增加健康牙本质的矿化,软化牙本质的再矿化和消毒曾受感染的牙本质。为避免由于去除最深层的软化牙本质而造成露髓,有人主张采用间接盖髓术,用氢氧化钙封闭洞底残存的软化牙本质,使周围及已脱钙的部位愈合。 Calcium hydroxide for deep caries treatment increases mineralization of healthy dentin, softens dentin remineralization, and sterilizes previously infected dentin. In order to avoid demyelination due to removal of the deepest demineralized dentin, it is advocated that indirect capping be used to seal the softened dentin remaining in the cave bottom with calcium hydroxide to heal the surrounding and decalcified sites.
