Mta CEMENT MINIRAL TRIOXIDE

MTA Plus is a specialized dental cement based on Di and Tri-Calcium Silicate, derived from advanced material research in inorganic hydraulic powder technology. MTA Plus is indicated for both vital pulp therapy and Endodontics procedures.

INDICATIONS:

Dental procedures contacting vital pulp tissue such as:

• Pulp capping
• Cavity lining
• Pulpotomies

Dental procedures contacting the periradicular tissues such as:

• Root-end fillings
• Apexification
• Perforation repair
• Root resorption
• Sealing
• Obturation (pulpectomy)

CONTRAINDICATIONS:

Hypersensitivity against caustic (high pH) solutions.

PRECAUTIONS: 

• AVOID contact of unset mixed paste with skin or oral mucosa. After incidental contact, wash and rinse with water.
• Wear suitable gloves and protective glasses during use.
• MTA Plus™ powder and gel must be kept well sealed.
• PROTECT the powder from humidity. Close the container.
• DO NOT contaminate the powder with an unclean or moist instrument.
• DO NOT overfill the root canals when obturating or sealing.

ADVERSE REACTIONS:

Reversible acute inflammation of the oral mucosa if contacted with the unset paste.

INTERACTIONS WITH OTHER DENTAL MATERIALS:

None known.

STORAGE:

Store at room temperature (25°C/75°F); do not refrigerate. Keep bottles tightly closed. Moisture will reduce the shelf life of the powder.

STEP-BY-STEP INSTRUCTIONS:

Dosage and Mixing:

a) Dispense 1 scoop of MTA Plus™ powder on a glass slab or a non-absorbent pad.

b) Dispense one small drop of MTA Plus Gel, OR some of the MTA Plus Liquid from 1 ampoule next to the powder. NOTE: The gel imparts washout resistance (for easier rinsing) and faster setting, which the Liquid does not. NOTE: MTA Plus Liquid ampoules are larger than unit-dose size.

c) Gradually mix the liquid or gel into the powder until the desired putty-like consistency is obtained. For some procedures, a thinner, syrupy, stringy consistency may be desired. Thoroughly mix to hydrate the powder.

d) If the material is not to be used immediately, cover the mixed material with a moist gauze sponge (use sterile water), or a clean cover to prevent evaporation. Extra gel or MTA Plus liquid may be used to rewet the powder before it sets.

MTA Plus™ material may be used for a variety of dental procedures such as:

•  Pulp-capping
•  Cavity lining
•  Pulpotomies
•  Apexification of primary teeth
•  Root-end filling
•  Internal/external root resorption
•  Repair of perforations
•  Obturation/pulpectomy and sealing
