BACKGROUND
The aim of this study was to compare the ability of MTA and Biodentine to set in the presence of human blood and minimal essential media.
MATERIALS AND METHODS
Eighty 1 x 3 inches plexi glass sheets were taken. In each sheet, 10 wells were created and divided into 10 groups. Odd number groups were filled with MTA and even groups were filled with Biodentine. Within these groups 4 groups were control groups and the remaining 6 groups were experimental groups (i.e., blood, minimal essential media, blood and minimal essential media). Each block was submerged for 4, 5, 6, 8, 24, 36, and 48 hours in an experimental liquid at 370C with 100% humidity.
RESULTS
The setting times varied for the 2 materials, with contrasting differences in the setting times between MTA and Biodentine samples. Majority of the MTA samples did not set until 24 hrs. but at 36 hours all the samples of MTA are set. While for Biodentine samples, all of them had set by 6 hours. There is a significant difference in setting time between MTA and Biodentine.
CONCLUSION
This outcome draws into question the proposed setting time given by each respective manufacturer. Furthermore, despite Biodentine being marketed as a direct competitor to MTA with superior handling properties, MTA consistently set at a faster rate under the conditions of this study.
