Comparative Analysis of the Physical Properties of Three Different Tricalcium Silicate Cements: An In Vitro Study

Calcium trisilicate materials, including biodentine, are popular choices for dental restorations owing to their biocompatibility. However, their compressive strength often falls short of ideal levels for certain restorative procedures. This research investigates the new biodentine formulation in the market, augmented with barium oxide to improve compressive strength and examines its physical characteristics.

Three distinct material groups were subjected to compressive strength testing. Group A comprised mineral trioxide aggregate (white MTA, Angelus, Londrina, Brazil), group B consisted of biodentine (Septodont, Saint-Maur-des-Fossés, France), and group C featured the new commercially available biodentine formulation in the market, Kedo Bio D+ (Kedo Dental, Chennai, India). A universal testing machine was employed to conduct the compressive strength tests under standardized conditions.

Across all time intervals, group C consistently displayed the highest average compressive strength, followed by group B, while group A showed the lowest values. The differences in compressive strength between the three groups were statistically significant (p = 0.001) after 7 days. The new biodentine formulation in group C withstood the highest maximum force, approximately 1,639 N, emphasizing its superior compressive strength compared with the other materials.

This study demonstrated that the incorporation of barium oxide in Bio D+ formulation significantly enhanced its compressive strength compared with conventional biodentine and MTA. Kedo Bio D+ exhibited superior mechanical properties, making it a promising material for dental restorations requiring increased strength and durability.
