A 5-yr follow-up randomized clinical multi-centre data has shown that a less invasive carious removal strategy has a significantly better outcome, than a non-selective carious removal strategy, in terms of preventing pulp exposure (Bjørndal et al. 2017, JDR). In case of a pulp exposure, only 9% of the analyzed capped pulps from the above trial were assessed as successful, indicating a low prognosis for conventional pulp-capping procedures in well-defined deep carious lesions in adults. This raises some questions; was the degree of pulp inflammation too advanced? Was the methodology performed poor? The penetration depths of the carious lesion may be an important prognostic factor? In many of the previous capped teeth, from where we have our current data, surprisingly little information is given about the prehistory of the carious lesion depth. It is well-known that the outcome seems different when pulp capping is performed within an infected environment (i.e. a cariously exposed pulp) as oppose to a traumae scenario. Although, the available evidence is sub-optimal, it seems reasonable to hypothesize that capping an initial infected environment, provides the risk of a lower success than capping a traumatically induced pulpal exposure. High demands of the pulp capping protocol will be required when infected pulps are to be capped versus capping the sound pulp. The standard and principles on when we should avoid or perform pulp invasive treatments is presented following the current Position Statements from European Society of Endodontology on Deep caries management.
