objective measures of pulpal inflammation such as carious lesion depth, as well as clinical indicators of activity including progression rate, colour, sensibility tests (ESE, 2019) and potentially pulpal inflammatory biomarkers (Ballal et al., 2021) should perhaps be used as the basis of a more functional classification moving forwar dakin to those used for facial pain (Pigg et al., 2021) or in Periodontology (Papapanou et al., 2018).
