Angelus MTA – 2 Dose

Angelus MTA –  2 Dose

• Ions calcium release
• Hydrophilic
• High alkalinity
• Low solubility

Angelus MTA Indications:

• Treatment of root canal and furcation perforations
• Sealing of internal resorption
• Surgical treatment of root perforation due to internal resorption
• Reverse filling in periapical surgery
• Pulp capping
• Pulpotomy (removal of affected coronal pulp to preserve vitality of remaining pulp tissue)
• Apexigenesis (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)

Features:

• Ions Calcium Release: enhances formation of mineralized tissues; provides biological seal of perforations and total repair of damaged periradicular tissues
• 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

Which are the main properties of MTA?

CHEMICAL:
Release of calcium ions: allows formation of mineralized tissues
Highly alcaline: prevents bacterial growth
BIOLOGICAL
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
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.
