DIRECTIONS TO USE
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.
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.
Dental procedures contacting vital pulp tissue such as:
- Pulp capping
- Cavity lining
Dental procedures contacting the periradicular tissues such as:
- Root-end fillings
- Perforation repair
- Root resorption
- Obturation (pulpectomy)
CONTRAINDICATIONS: Hypersensitivity against caustic (high pH) solutions.
- 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.
- Store at room temperature (25°C/75°F); do not refrigerate.
- Keep bottles tightly closed.
- Moisture will reduce the shelf life of the powder
