This procedure is carried out when there is gross loss of dentine due to caries, trauma, or previous iatrogenic intervention and a cavity exists where a large portion of the soft tissue of the pulp is exposed and bleeding, suggesting inflammation or contamination, or where it is not possible to obtain haemostasis at a superficial level. Full pulpotomy is defined as complete removal of the coronal pulp to the root canal orifice level, followed by application of a material directly on to the remaining pulp with the aim of producing a positive biological response so that the pulp can protect itself (Figure 2.6).
