The tooth should be isolated with a rubber dam and asepsis should be maintained throughout cavity preparation. The cavity should be disinfected using cotton pellets soaked with sodium hypochlorite (0.5–5%). Less invasive carious tissue‐removal techniques are generally carried out using sterile round burs and excavators [79], but other self‐limiting chemomechanical methods (e.g. Carisolv gel) have also been advocated for the management of deep carious lesions [80]. Regardless of the technique employed, carious tissue should be removed from the periphery of the cavity to hard dentine (i.e. nonselective removal), leaving soft or leathery dentine only on the pulpal aspect of the cavity. As RDT over the pulp cannot be accurately assessed clinically, the use of a biologically based biomaterial is recommended. Ideally, an HCSC or a glass ionomer cement (GIC) should be routinely applied to the dentine barrier prior to definitive restoration (Figure 2.3) [1, 27].
