The aim of this study was to investigate the effect of human blood exposure on the compressive strength of various calcium silicate‐based cements. Two hundred and eighty‐eight customised cylindrical moulds were randomly divided into three groups according to material used: ProRoot MTA , Biodentine or CEM cement ( n = 96). Each group was divided into two subgroups according to exposure conditions: PBS or blood. Then, the compressive strength of the specimens was measured after 6 h, 24 h, 72 h and 7 days. The compressive strength of CEM cement could not be measured after 6 and 24 h regardless of the exposure conditions nor could the compressive strength of 6 h blood‐exposed ProRoot MTA . The compressive strength of blood‐exposed ProRoot MTA was only significantly lower after 6 h, but no difference was seen at other time intervals. Blood exposed did adversely affected the compressive strength of Biodentine. The compressive strength of all groups significantly increased over time ( P < 0.005).
