Abstract
This systematic review focus on the biocompatibility of Portland cement (PC), a material used in direct pulp capping of human teeth. Research was done using MEDLINE, LILACS, BBO, Cochrane Library, SciELO, PubMed and the CAPES thesis data base. A total of 12 publications were selected. Two examiners searched for randomized, non randomized clinical trials, case-control, cohort and transversal studies, focusing on human beings. In vitro studies, studies in animals, literature review, letters and editorials were excluded. Ten studies were excluded because they didn’t meet the inclusion criteria. Thus, only 2 studies made up the sample. The latter showed that PC provided excellent results in direct capping and behaves similarly to Mineral Trioxide Aggregate (MTA) when used in this sort of treatment. This systematic review found that there is still little research on the biocompatibility of PC in direct capping in humans and for that reason, additional studies should be undertaken.
