Summary
Selenium nanoparticles (SeNPs) reduce the alkalinizing potential of Mineral Trioxide Aggregate (MTA HP), making it more suitable for pulpal tissue applications. This study confirms SeNP integration and its impact on MTA HP
Area of Science:
- Biomaterials Science
- Dental Materials
- Nanotechnology
Context:
- Mineral Trioxide Aggregate (MTA HP) is widely used in endodontics and regenerative dentistry.
- Its high alkalinity can sometimes cause tissue irritation.
- Selenium nanoparticles (SeNPs) offer potential for material modification.
Purpose:
- To investigate the effect of incorporating SeNPs into MTA HP on its alkalinizing potential.
- To characterize the morphological and elemental changes in MTA HP after SeNP addition using FE-SEM/EDX.
- To assess the pH changes over time with varying SeNP concentrations.
Summary:
- SeNPs were successfully dispersed and integrated into the MTA HP matrix, confirmed by FE-SEM/EDX.
- MTA HP with increasing SeNP concentrations showed a significant reduction in alkalinizing activity compared to the control.
- pH levels decreased significantly with SeNP incorporation across all tested concentrations and time points (1-30 days).
Impact:
- The addition of SeNPs modulates the high pH of MTA HP, potentially reducing adverse tissue reactions.
- SeNP-modified MTA HP may be more suitable for direct application in pulpal tissue and regenerative procedures.
- This research enhances understanding of SeNP-MTA HP interactions, paving the way for improved dental biomaterials.
