Abstract

Aim: To evaluate the effect of oral tissue fluids like saliva and blood on compressive strength of MTA and biodentine. Material and method: The present study was done in the Department of Dentistry. A total of 30 freshly extracted mandibular premolars were collected and used in the study. A total of 30 cylindrical samples were prepared with internal diameter of 4 mm width and 6 mm length using acrylic blocks. Both MTA and biodentine were manipulated based on manufacturer’s instructions. The moulds were coated with saliva or blood according to the group before placement of the material and a glass slab was placed at the base of the material to generate a smooth surfaced base. Finally compressive strength was evaluated. Data were tabulated and examined using the Statistical Package for Social Sciences Version 22.0 (IBM SPSS Statistics for Mac, Armonk, NY: IBM Corp, USA). Results: On contamination with oral tissue fluids like saliva and blood, there was no statistical significant difference in the compressive strength between the three groups i.e., MTA, MTA-S, MTA-B (p>0.05). Also, there was no statistical significant difference between BD, BD-S, BD-B (p>0.05). Conclusion: The results of the present study concluded that the compressive strength of MTA and biodentine was similar in comparison, both under normal as well as in contaminated conditions.
