Hydraulic Silicate Cement (HSC), a type of Mineral Trioxide Aggregate (MTA), offers significant dental benefits like sealing and sterilization. Further research into its handling and physiological effects is recommended for optimal clinical application.
Area of Science:
- Endodontics
- Biomaterials Science
- Dental Materials
Background:
- Mineral Trioxide Aggregate (MTA) and ordinary Portland cement (OPC) are widely used in endodontics.
- MTA exhibits excellent sealing, sterilizing, mineralizing, dentinogenic, and osteogenic properties.
- Ad hoc modifications to MTA often lack strong scientific justification.
Purpose of the Study:
- To review the current understanding of Portland cement-like endodontic materials (MTA).
- To propose a generic name, Hydraulic Silicate Cement (HSC), for this material class.
- To outline the setting reaction scheme for HSC.
Main Methods:
- Comprehensive literature search from January 2005 to December 2009 using keywords like 'MTA', 'GMTA', 'WMTA', and 'mineral trioxide aggregate'.
- Searched databases including ScienceDirect, SAGE Journals Online, Wiley Online Library, SciELO, JSTOR, and Scopus.
- Cross-referenced articles and searched manufacturer websites for additional information.
Main Results:
- A generic name, Hydraulic Silicate Cement (HSC), is proposed for MTA-like materials.
- An outline of the HSC setting reaction scheme has been deduced.
- HSC demonstrates significant advantages in sealing, sterilization, mineralization, dentinogenesis, and osteogenesis.
Conclusions:
- Hydraulic Silicate Cement (HSC) has a valuable role in dentistry with fewer drawbacks than other materials.
- Improvements in handling and other properties of HSC are desirable.
- Further studies on the mechanisms of HSC's beneficial physiological effects are needed, potentially drawing insights from OPC literature.
