A 0.5% basic fuchsin-propylene glycol solution was applied to the carious dentin of extracted and vital human teeth, and the depths of the fuchsin-stained dentin and the bacterial invasion were compared on histological sections. Excavation guided by this staining method was always deeper than the bacterial invasion, with differences between the depths being greater in acute decay than in chronic decay. This staining is considered to be a reliable clinical guide for the complete removal of deteriorated dentin without causing failure to remove the infection completely. The depths of the images of dentin caries on the radiographs before treatment and after excavation guided by the fuchsin staining method were also compared. The image on the radiograph was always shallower than the excavated cavity. Dentists must expect to excavate caries cavities somewhat deeper than radiographic images.
将0.5%的碱性品红 - 丙二醇溶液应用于拔除的以及活的人牙的龋坏牙本质上，并在组织学切片上比较品红染色牙本质的深度和细菌侵入的深度。这种染色方法引导的窝洞预备总是比细菌侵入更深，急性龋中两者深度的差异比慢性龋更大。这种染色被认为是一种可靠的临床指导，可确保完全去除龋坏牙本质而不会导致未能完全清除感染。还比较了品红染色法引导下窝洞预备前后X线片上龋坏牙本质影像的深度。X线片上的影像总是比窝洞预备后的洞腔浅。牙医必须预料到窝洞预备的深度要比X线片影像深一些。
