Abstract: The first article in this two-part series described the properties and use of hydraulic cements for intra-coronal applications, mainly for vital pulp therapy and as a barrier for regenerative endodontic procedures. In Part 2, the intra-radicular and extra-radicular uses are discussed. Hydraulic cements are a unique set of materials that set in the presence of water and, when set, they are resistant to deterioration in a damp environment. The use of hydraulic cements within the root canal (root canal sealer and apical plug) and when used at the periodontal–endodontic interface (perforation repair and root-end filler) is described and illustrated with clinical cases.

Clinical relevance: Hydraulic cements are indicated for a number of procedures in endodontics and this is supported by an extensive and increasing body of evidence with respect to their efficacy.
