Description
Bioceramic reparative cement
MTA is used for root canal perforation, root-end resection, apexification, pulp capping & pulpotomy.
INDICATIONS:
- Treatment of perforations of root canal and furcation caused iatrogenically or by caries lesion.
- Via canal treatment of root perforation due to internal resorption.
- Surgical treatment of root perforation due to internal resorption.
- Periapical surgery with reverse filling.
- Pulp capping.
- Pulpotomy (removal of affected coronal pulp to preserve vitality of remaining pulp tissue).
- Apexogenesis (induction of root development in vital teeth with an inflamed coronal pulp).
- Apexification (induction of formation of a mineralized barrier at the root tip of young permanent teeth with incomplete root development and a necrotic pulp).
Directions For Use
Oral rehabilitation in patients with parafunctional habits Use of the direct core with fiber post should only be indicated to
teeth with a minimum height of 2 mm of coronal dentin Fiber posts should only be cut with water refrigerated high speed diamond burs. Do not use scissors or cutting pliers. Use goggles and a mask to prevent inhalation of particles generated
during cutting Fiber posts must be completely covered by the cementing agent or the composite resin. Exposed fibers absorb water which deteriorates the mechanical properties of the posts.
FAQs
WHICH ARE THE MAIN PROPERTIES OF MTA?
Chemical:
Release of calcium ions: allows formation of mineralized tissues.
Highly alcaline: prevents bacterial growth.
Physics
Low solubility: may be used directly on pulp and periapical tissues.
Compressive strength: 44.2 MPa – may be used as base for restorations.
Expansion after hydration: seals cavities completely.
Setting time (15 minutes): may be used in single appointment.
Radiopaque: allows radiographic control.
Biológicas
Biocompatibility: may be used directly on living tissues.
New formation of cement: only dental material with this capacity.
Remineralization of dentin: allows formation of biologic barrier.
Biologic sealing of perforations: complete healing of periapical tissues.
WHAT IS THE DIFFERENCE BETWEEN GRAY MTA AND WHITE MTA?
White MTA has less iron oxide in its composition. This substance is the responsible for the
darker color of the Gray MTA. Such reduction in the levels of iron oxide does not interfere
with the great properties of the cement MTA.
WHICH ARE THE INDICATIONS OF MTA?
- Treatment of root canal perforation
- Treatment of furcation perforation
- Treatment of root canal resorption
- Retrofilling in periapical surgeries
- Direct pulp capping
- Pulpotomy
- Apexigenesis
- Apexification
- Intracoronal barrier during tooth bleaching
- Apical plug
HOW IS MTA APPLIED?
The consistency of MTA is different when compared to conventional dental materials. Its application may be performed with insertion spatulas, amalgam carriers or instruments specially designed for MTA handling (e.g., MTA Carrier and MAp System). MTA should never be used with a Lentulo spiral because it needs to be directly placed in the area to be repaired.
WHY IS THE SETTING TIME OF MTA ANGELUS FASTER THAN OF THE OTHER BRANDS?
Since 2002, the setting time of MTA Angelus was modified from 2.5 hours to 15 minutes.
This reduced setting time is exclusive of Angelus. The concentration of calcium sulfate, which is the substance responsible for the long setting time, was decreased. MTA Angelus allows final restorative treatment in the same clinical appointment of MTA insertion.
CAN MTA BE USED AS A FINAL ROOT CANAL FINAL FILLER?
MTA does not have a proper consistency (flow) for final root canal filling. Also, after its
setting, removal would be extremely difficult if reentry is necessary.
