Can MTA be used for obturation?

Abstract. Mineral trioxide aggregate (MTA) has emerged as a reliable bioactive material with extended applications in endodontics that include the obturation of the root canal space.

What is MTA obturation?

MTA canal obturation offers an innovative method to approach challenging endodontically involved teeth that may not respond using traditional filling materials and sealers when extensive pathosis is present.

What is MTA used for in dentistry?

MTA is used for creating apical plugs during apexification, repairing root perforations during root canal therapy, treating internal root resorption, and pulp capping. The objective of this article is to investigate MTA features from a clinical point of view, even compared with other biomaterials.

How do you put a MTA on a root canal?

The MTA powder is mixed with sterile water, and the mixture is placed in contact with the exposure using a Dovgan carrier (Figure 2). Compress the mixture against the exposure site with a moist cotton pellet. Place a moist cotton pellet over the MTA and fill the rest of the cavity with a temporary filling material.

What is the best obturation technique?

MTA Endodontics - Obturating a Canal w/ MTA

What are the different techniques of obturation?

the various techniques used these days for filling internal resorption include warm condensation, vertical condensation, core techniques, thermoplasticized gutta-percha, warm vertical compaction, and cold lateral condensation.

What are obturation techniques?

What The Term “Obturation” Means in Endodontics. Dentists who perform fillings, root canal procedures, and other restorative methods of filling a tooth have to be skilled in obturation. Obturation is the technical term for a method of filling and sealing a tooth with root canal material.

Can MTA be used for pulp capping?

MTA is a new and biocompatible biomaterial used for dental practice. It has been proved to be an excellent material for repairing of root perforations, apexification, root-end filling, repairing of root resorption and pulp capping.

How long does it take MTA to set?

It has been reported that MTA sets slowly approximately 3-4 hours in clinical conditions (3, 25). Long setting time of MTA can cause clinical problems.

Is MTA resorbable?

This condition can occur during a direct contact between extruded MTA and body tissue fluids, which may be partially responsible for MTA resorption. Bismuth oxide, an insoluble radiopacifier, cannot be resorbed in this way and, therefore, the aforementioned mechanism of action is not applicable to this component.

Does MTA bond to tooth?

Nowadays, the material that offers the best sealing characteristic in the field of endodontic treatment is the mineral trioxide aggregate (MTA), nevertheless, this material necessities an adhesive bonding agent to perfectly join to the dental surface.

Is MTA a liner or a base?

MTA provides a higher incidence and faster rate of reparative dentin formation without the pulpal inflammation. MTA Plus material is also indicated for base and liner in vital pulp therapy. In root-end filling after apicoectomy, the anti-washout agent (chitosan or gelatin) is useful to prevent from MTA washout.

Can MTA be mixed with saline?

The high sealing ability of MTA in combination with normal saline has been supported by all these studies. Also our study proved the superiority of the combination of MTA with normal saline compared to 5% CaCl₂ and KY Jelly.

What are the advantages of MTA?

MTA has the advantage of being less soluble than calcium hydroxide and offers an enhanced seal due to its setting expansion which hermetically seals the pulp space, preventing bacterial contamination from the outside.

How do you remove the MTA from a root canal?

Removal of MTA from dentin by applying 37% hydrochloric acid (HCl) to reduce microhardness and push-out bond strength.

What is the pH of set MTA?

pH. Hydrated MTA has an initial pH of 10.2, which rises to 12.5 (similar to calcium hydroxide) 3 hours after mixing and following setting. The high pH is theorized to be responsible for the antimicrobial action and biological activity of the material.

Which is better MTA or calcium hydroxide?

MTA is more effective and superior comparing the Calcium Hydroxide as a direct pulp capping material, showed higher success rate with favorable outcomes in maintaining long term tooth vitality and easier to use in pulp capping. MTA is less toxic, less pulpal inflammation capping compared to Calcium Hydroxide.

What does MTA do to pulp?

The researchers have reported that MTA induces proliferation of pulp cells,41, 42 it stimulates osteoblasts to release interleukins⁴ with formation of hard tissue,⁴³ and an interface with the dentin that is very similar in composition to the hydroxyapatite.

Is Biodentine same as MTA?

Biodentine is comparatively a new biomaterial claimed to have properties comparable to mineral trioxide aggregate (MTA). Biodentine and MTA are effectively used for direct pulp capping (DPC), and they are capable of regenerating relatively damaged pulp and formation of hard dentine bridge.

What are the criteria for obturation?

The radiographic criteria for evaluating obturation include the following categories: length, taper, density, GP and sealer removal to the facial cementoenamel junction in anterior teeth and to the canal orifice in posterior teeth, and an adequate provisional or definitive restoration (Fig. 9.12).

How do you Obturate in RCT?

What is master cone in RCT?

Customized master cones represent a change in concept: rather than instrumenting the root canal to fit the shape of a round, industrial, master cone, a cone is prepared to fit the shape of the ready-to-fill canal.

What is single cone obturation?

The single-cone technique comprises the use of a single gutta-percha point at environment temperature, with a variable cement thickness depending on the adaptation of the point to the root canal walls ².

What is BMP in RCT?

What is BMP in Root Canal Treatment? Biomechanical preparation is the achievement of free access to the apical foramen via the root canal by mechanical means. It is directly related to subsequent disinfection and filling.
