| Abstract
Objectives: The push‐out bond strength (POBS) of calcium silicate‐based cements
(CSCs) to the dentinal wall is considered one of the essential physical properties for
clinical success. The presence of blood in the treatment area affects the POBS of
these types of cement. This study aimed to evaluate the impact of blood contamination
on the bond strength of CSCs and dentinal walls.
Material and Methods: This systematic review was performed by searching electronic
databases (MEDLINE‐PubMed, Scopus, and EMBASE) to include relevant in
vitro studies published between 1992 and April 2020. Two reviewers independently
evaluated the selected studies and extracted data on the type of studied CSCs,
evaluated area of the teeth, sample size, the dimension of a prepared area, slice
thickness, storage duration, the setting of the universal testing machine (UTM),
effects of blood contamination on POBS of CSCs and their failure modes. The bond
strength of evaluated CSCs in studies was used for network meta‐analysis.
Results: Initial searches identified 292 articles, while only 13 articles met the inclusion
criteria. Full texts of these articles were evaluated, and data extraction was
performed. The effect of blood contamination on bond strength to the dentinal wall
was assessed in various CSCs such as PMTA, Biodentine, and AMTA. The network
meta‐analysis results showed that the bond strength of Biodentine was significantly
higher than other types of cement in blood presence (p < .05).
Conclusions: Based on the current systematic review, despite controversies among
the result of the different articles and the lack of data for some CSCs like bioaggregate,
it could be concluded that the bond strength of Biodentine to the dentinal
wall is better than other evaluated CSCs in the presence of blood. |
