✅ Physical and Chemical Characteristics of MTA
° Main components: Tricalcium silicate, tricalcium aluminate, calcium oxide, silica, and bismuth oxide for radiopacity.
° Initial pH: Around 10.2, rising to 12.5 after setting—contributing to its antimicrobial action.
° Setting time: Between 2 to 4 hours, depending on formulation and moisture.
° Biocompatibility: Well-tolerated by periapical tissues and does not provoke significant inflammation.

The video that we share details everything related to pulpectomy: diagnosis, indications and contraindications, procedure, recommended filling materials, and the importance of post-treatment follow-up.✅ Mechanism of Action
MTA promotes dentin bridge formation by stimulating mesenchymal stem cells to differentiate into odontoblast-like cells. Its high pH provides an antimicrobial environment while enhancing mineralization, aiding in pulp healing and hard tissue regeneration.
✅ Clinical Benefits of MTA in Pediatric Dentistry
° Excellent biocompatibility, making it safe for use in primary and immature permanent teeth.
° Superior sealing ability, preventing bacterial microleakage.
° Stimulates pulp regeneration and dentin formation.
° High pH provides antimicrobial effects without the cytotoxicity of other materials.
° Versatile applications in both vital and non-vital pulp therapy.

Recent studies and systematic reviews confirm that MTA outperforms traditional materials such as formocresol and calcium hydroxide in pulp therapy of primary teeth. Although its cost and long setting time have been noted as limitations, newer versions address these issues. MTA offers higher long-term success rates, reduced pathologic root resorption, and superior tissue integration.
In U.S. pediatric dental practice, MTA has become the material of choice for many pulp procedures, especially when long-term tooth preservation is the goal.
💡 Conclusion
MTA is a clinically proven, biologically superior material for managing pulp tissues in pediatric patients. Its biocompatibility, sealing properties, and regenerative potential make it ideal for pulpotomies, apexification, and other endodontic procedures. Although cost may be a consideration, the high clinical success justifies its use as a standard of care in pediatric endodontics.
