“…Seven studies were excluded because of evaluating the effects of blood contamination on cylindrical molds of CSCs without using tooth samples (Adl et al, 2015 ; Bolhari et al, 2020 ; Nekoofar et al, 2010 ; Oloomi et al, 2013 ; Shalan, 2012 ; Sheykhrezae et al, 2018 ; Singla et al, 2018 ; Subramanyam & Vasantharajan, 2017 ).

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.

“…The findings of our study can be correlated well with those of Neekofar et al, 36 Ustun et al, 37 Ratih and Putri, 38 and Subramanyam and Vasanthrajan. 39 According to them, an interfacial gap created between MTA and radicular dentine in the presence of blood is because of air entrainment caused by hemoglobin and blood proteins like albumin which not only have adverse effects on marginal adaptability but also create porous voids, thus reducing the sealability of MTA and disocclusion of MTA and dentinal tubules.…”

Aim and objective The present study was conducted to evaluate the marginal adaptability of mineral trioxide aggregate (MTA) as a root-end filling material when manipulated using two different IV fluids intended for pediatric usage; in the presence of blood and salivary contamination. Materials and methods Sixty single-rooted teeth were selected. Conventional endodontic root canal preparation was performed on all specimens followed by root-end resection and retrograde cavity preparation. The roots were randomly divided into two groups ( n = 30). In the specimens of group I, fresh blood was used as a contaminant and in group II artificial saliva was used as a contaminant. In both groups, MTA (e-MTA, Kids-e-Dental®) manipulated using either Ringer's lactate IV fluid ( n = 15) or Tetraspan IV fluid ( n = 15) was used for root-end filling in blood or artificial saliva-coated retrocavities. Furthermore, these roots were placed in beakers pooled with fresh phlebotomized blood or artificial saliva. After incubating for 48 hours, the roots were divided longitudinally to expose the retrofilled cavities and were then sputter-coated with gold-platinum dust. To assess the marginal adaptation of MTA to radicular dentin “maximum gap width” and “gap perimeter” were measured in images obtained from scanning electron microscopy of root specimens. SPSS 21 was employed for statistical analysis at ( p < 0.05). Mann–Whitney U test and ANOVA were used for analyzing the data obtained. Results The gap width was more among samples exposed to blood ( p < 0.05) than artificial saliva. No significant difference was reported in the gap perimeter when cavities were filled with MTA mixed with either IV fluids ( p > 0.05). Conclusion Exposure to blood during setting had a negative effect on gap width when retrocavities were filled with MTA using Tetraspan. No effect was seen on the arch perimeter in retrocavities filled with MTA mixed with Ringer's lactate or Tetraspan. Clinical significance For avoiding failure, it is critical to select a biocompatible root-end filling material with high sealing ability. Hence, by doing the same, the clinical situation can be simulated. How to cite this article Mody A, Arora R, Chauhan P, et al.

“…Moreover, no changes must occur in physical properties due to acid etching before the placement of composite restoration [ 48 ]. The acid etching process [ 49 ], as well as saliva and blood from the oral cavity [ 50 ], had no negative impacts on Biodentine and ProRoot MTA compressive strength, and these calcium silicate-based cements seem to be better options.…”

Regarding the common use of calcium silicate cements (CSCs) in root canal therapy, their position in the context of past and present dentistry agents can provide a better understanding of these materials for their further improvement. In this context, the present review article addresses a wide range of recent investigations in the field of CSC-based products and describes details of their composition, properties, and clinical applications. The need for maintaining or reconstructing tooth structure has increased in contemporary endodontic treatment approaches. This research thus discusses the attempts to create comprehensive data collection regarding calcium ion release, bond strength, alkalinizing activity and bioactivity, and the ability to stimulate the formation of hydroxyapatite as a bioactive feature of CSCs. Sealing ability is also highlighted as a predictor for apical and coronal microleakage which is crucial for the long-term prognosis of root canal treatment integrity. Other claimed properties such as radiopacity, porosity, and solubility are also investigated. Extended setting time is also mentioned as a well-known drawback of CSCs. Then, clinical applications of CSCs in vital pulp therapies such as pulpotomy, apexification, and direct pulp capping are reviewed. CSCs have shown their benefits in root perforation treatments and also as root canal sealers and end-filling materials. Nowadays, conventional endodontic treatments are replaced by regenerative therapies to save more dynamic and reliable hard and soft tissues. CSCs play a crucial role in this modern approach. This review article is an attempt to summarize the latest studies on the clinical properties of CSCs to shed light on the future generation of treatments.
