Why is MTA biocompatible?

A study by Nunez et al. [28] stated that both MTA and biodentine are analogous in terms of biocompatibility with potential to provide positive environment for the cell, showing cell proliferation and osteogenic capability.

What is the use of MTA in dentistry?

MTA is used for creating apical plugs during apexification, repairing root perforations during root canal therapy, treating internal root resorption, and pulp capping. The objective of this article is to investigate MTA features from a clinical point of view, even compared with other biomaterials.

Is MTA cytotoxic?

Overall, all four MTA products tested showed severe cytotoxicity at 100% and 50% extracts, while 25% and 12.5% revealed 30∼100% depending on the MTA products during setting. Endocem MTA still showed severe cytotoxicity at 12.5% extract, while others showed relatively higher cell viability compared to Endocem MTA.

Is Biodentine better than MTA?

Biodentine is found to be associated with high pH (12) and releases calcium and silicon ions which stimulates mineralization and create “mineral infiltration zone” along dentin-cement interface imparting a better seal. Caron G et al., have found that Biodentine exhibits superior sealing properties than MTA [24].

Can MTA be used in primary teeth?

MTA as a pulpotomy agent has shown favorable results in case of primary molars. There is limited literature available regarding its use in primary incisors. However, the success of vital pulp therapy with MTA depends on proper case selection and technique of management of the tooth than the material itself.

(FR) SendoSeal MTA | Simple. Sûr. Biocompatible.

Is MTA used in Pulpectomy?

MTA is recommended as an option pulpectomy material for nonvital primary teeth with no permanent successors, but it is important to improve the long-term clinical studies to confirm its benefit in such cases.

Can use MTA with pulpotomy?

MTA may be used as an alternative pulpotomy agent in immature teeth with pulp exposure to stimulate pulp healing with dentin bridge formation and complete root formation.

Is MTA same as Biodentine?

Background: Biodentine is comparatively a new biomaterial claimed to have properties comparable to mineral trioxide aggregate (MTA). Biodentine and MTA are effectively used for direct pulp capping (DPC), and they are capable of regenerating relatively damaged pulp and formation of hard dentine bridge.

Is MTA a bioceramic?

The first-generation bioceramic or hydraulic cement introduced in endodontics is mineral trioxide aggregate (MTA) in the 1990s by Dr. M. Torabinejad. Hydraulic cements refer to a material that needs hydration to set and once set are impervious to dissolution in water.

What is Biodentine used for?

Abstract. Biodentine is a calcium-silicate based material that has drawn attention in recent years and has been advocated to be used in various clinical applications, such as root perforations, apexification, resorptions, retrograde fillings, pulp capping procedures, and dentine replacement.

What are the advantages of MTA?

MTA has the advantage of being less soluble than calcium hydroxide and offers an enhanced seal due to its setting expansion which hermetically seals the pulp space, preventing bacterial contamination from the outside.

How does MTA work?

The MTA will provide structure and strength to the tooth by replacing the resorbed tooth structure. In external resorption, after root canal therapy is performed, the flap is raised over the tooth and the defect removed from the root surface with a round bur.

What is the difference between MTA and calcium hydroxide?

MTA is more effective and superior comparing the Calcium Hydroxide as a direct pulp capping material, showed higher success rate with favorable outcomes in maintaining long term tooth vitality and easier to use in pulp capping. MTA is less toxic, less pulpal inflammation capping compared to Calcium Hydroxide.

Is MTA resorbable?

This condition can occur during a direct contact between extruded MTA and body tissue fluids, which may be partially responsible for MTA resorption. Bismuth oxide, an insoluble radiopacifier, cannot be resorbed in this way and, therefore, the aforementioned mechanism of action is not applicable to this component.

What makes MTA radiopaque?

MTA- Angelus (Angelus, Londrina, Paraná, Brazil) is produced from Portland cement, with bismuth oxide added to increase radiopacity. Its properties, in terms of increasing pH and releasing calcium ions, are similar to Pro Root TM MTA (Dentsply Tulsa Dental, Tulsa, OK), as previously demonstrated by Duarte et al.

What is the main component of MTA?

Mineral trioxide aggregate (MTA) is composed of Portland cement, with 4:1 addition of bismuth oxide added so that the material can be detected on a radiograph. The cement is made up of calcium, silicon and aluminium. The main constituent phases are tricalcium and dicalcium silicate and tricalcium aluminate.

What is the pH of MTA?

pH. Hydrated MTA has an initial pH of 10.2, which rises to 12.5 (similar to calcium hydroxide) 3 hours after mixing and following setting. The high pH is theorized to be responsible for the antimicrobial action and biological activity of the material.

What is the ion for MTA?

Calcium hydroxide, a main by-product of PC, MTA, and CEM cement, has a pH of 12.5 (8,22,24). The antibacterial characteristic of CH is attributed to the release of hydroxyl ions (25).

When do you use indirect pulp capping?

Indirect pulp capping occurs when the pulp tissue is close to the surface but not completely exposed. It usually includes two treatments spaced six to eight months apart. The indirect pulp capping procedure involves: Removing decay.

What is MTA in pediatric dentistry?

Mineral trioxide aggregate (MTA), is unique endodontic cement that was initially introduced as a material for root perforation repair. Over the years its use has expanded to include versatile applications in the field of pediatric dentistry.

Why is pulpotomy not used in permanent teeth?

The issues associated with coronal pulpotomy in permanent teeth are uncertainty on the pulpal status at the time of treatment, lack of predictability, and absence of any scientific and valid evidence on long term follow-up and success rate [13].

What is neo MTA?

NuSmile NeoMTA2 is a stainproof bioactive bioceramic cement that is used universally for vital pulp therapy in primary and permanent teeth. The active ingredient, a blend of tricalcium silicate and dicalcium silicate, triggers the healing process by forming hydroxyapatite on its surface.

Why is formocresol used in pulpotomy?

Formocresol and ferric sulfate have been used as protective medicaments for partial or complete pulpotomy procedures, among other techniques, including electrosurgery and laser cautery. Ferric sulfate and formocresol staunch the bleeding pulp, but neither material is bioactive.

What is the difference between Vitapex and Metapex?

The compositions of Vitapex and Metapex are almost identical, with the main difference being the composition ratio of calcium hydroxide and iodoform.
