Ex Vivo Osteogenesis Induced by Calcium Silicate-Based Cement Extracts

Area of Science:

• Biomaterials Science
• Dental Materials
• Regenerative Medicine

Background:

• Calcium silicate-based cements (CSCs) are vital in pulp therapy, promoting tissue mineralization.
• Understanding CSCs' biological effects on bone development is crucial for their clinical application.

Purpose of the Study:

• To compare the osteogenic potential of fast-setting CSCs (Biodentine™, TotalFill® BC RRM™ Fast Putty) versus a slow-setting CSC (ProRoot® MTA).
• To evaluate the ex vivo biological response of embryonic chick bone development to CSC eluates.

Main Methods:

• Organotypic culture of embryonic chick femurs exposed to CSC eluates for 10 days.
• Assessment of osteogenesis and bone formation using microtomography and histomorphometry.

Main Results:

• All CSC eluates increased osteogenesis and tissue mineralization in a dose-dependent manner.
• Fast-setting cements (Biodentine™, TotalFill®) showed superior performance compared to ProRoot® MTA.
• Biodentine™ exhibited the most significant positive impact on bone development in this model.

Conclusions:

• Fast-setting CSCs, particularly Biodentine™, demonstrate enhanced osteogenic properties compared to ProRoot® MTA.
• CSCs effectively stimulate bone mineralization, supporting their use in regenerative endodontics and bone defect treatments.
