Prevest Mta Plus

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.

ADA 57, ISO 6876 and ISO 9917 criteria:-

• Working Time at room temperature: ~12 min when thickly mixed with gel
• Setting Time at 37°C: < 1 hr. when thickly mixed with gel
• Film thickness: 50 µm when mixed 1:1 Powder:Gel, otherwise higher
• Solubility: <2% o Dimensional stability after 30 days: <+0.1% expansion
• Radiopacity: 5 mm equivalent of aluminum
• Compressive strength: 80 MPa after 7 days when mixed 3:1 Powder:Gel
• Pb and As: 2 ppm

This material has been developed for professional dental use. Application should be carried out strictly according to the directions for use. Liability cannot be accepted for damages resulting from failure to observe the instructions of the stipulated area of application. The user is responsible for testing the material for its suitability and use for any purpose not explicitly stated in this instruction sheet. Descriptions and data constitute no warranty of attributes and are not binding.

STEP-BY-STEP INSTRUCTIONS:

Dosage and Mixing:

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