MTA ANGELUS WHITE
Proven efficiency in the perforations treatment
Product description
Bioceramic reparative cement
Indication
Treatment of the root canal perforations or furcation;
Sealing of internal and communicating root resorptions;
Retrofilling in endodontic surgeries;
Pulp capping in treatments;
Pulpotomy;
Apexification;
Apexogenesis
Advantages
- Ions Calcium Release: enhances formation of mineralized tissues; provides biological seal of perforations and total repair of damaged periradicular tissues.
- Capable of inducing neoformation of periradicular cementum: Biological action.
- Hydrophilic: can be used in humid areas without losing properties.
- High alkalinity: antibacterial properties.
- Low solubility: does not allow leakage.
- Calcium oxide: promotes tissue biocompatibility.
- Aggregated oxides: Great compressive strength.
- High radiopacity: higher radiopacity than that of dentin, allowing excellent radiographic visualization.
- Setting time of 15 minutes: shorter setting time than similar cements.
704-0050 MTA Angelus White - 5Gm. Per box
Contains: 5-1 Gm. MTA Glass bottles, 1-3 ml bottle distilled water & 1 plastic measuring scoop
1 - Which are the main properties of MTA?
• CHEMICAL
Release of calcium ions: allows formation of mineralized tissues
Highly alcaline: prevents bacterial growth
• PHYSICAL
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
• BIOLOGIC
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
2 - 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.
3 - 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.
4 - 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.
5 - 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.
6 - 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.
