What is the difference between MTA and calcium hydroxide?

MTA is more effective and superior comparing the Calcium Hydroxide as a direct pulp capping

pulp capping

Pulp capping is a technique used in dental restorations to prevent the dental pulp from necrosis, after being exposed, or nearly exposed during a cavity preparation, from a traumatic injury, or by a deep cavity that reaches the center of the tooth causing the pulp to die.

Pulp capping - Wikipedia

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 is MTA in pulp capping?

Mineral trioxide aggregate (MTA) is a treatment option that may provide successful outcomes for the capping of carious pulp exposures in adult patients. However, the success measured as pulp survival over a period of one and two years of pulp caps performed by undergraduate dental students may be low.

Is MTA a calcium silicate?

Mineral trioxide aggregate (MTA) is a calcium silicate-based cement (CSC) commonly used in endodontic procedures involving pulpal regeneration and hard tissue repair, such as pulp capping, pulpotomy, apexogenesis, apexification, perforation repair, and root-end filling.

Why do we use calcium hydroxide in direct pulp capping?

Calcium Hydroxide Cavity Liners

Calcium hydroxide cements are used for lining specific areas of deep cavities or for direct pulp capping. The antibacterial action of calcium hydroxide makes these cements useful in indirect pulp-capping procedures involving carious dentin.

What is MTA in dentistry?

The mineral trioxide aggregate (MTA) is a dental material with biocompatibility properties to oral and dental tissues. MTA was developed for dental root repair in endodontic treatment and it is formulated from commercial Portland cement, combined with bismuth oxide powder for radiopacity.

Is MTA calcium hydroxide?

Interestingly, the primary reaction product of MTA with water is Calcium Hydroxide, and so it is actually the formation of calcium hydroxide that provides MTA's biocompatibility [10,24- 27] As a result, many of the advantages and potential mechanisms of action for MTA are similar to Calcium Hydroxide, including its ...

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.

Is MTA used in indirect pulp capping?

Indirect pulp capping accompanying complete caries removal exhibited a satisfactory success rate in the treatment of deep carious lesions. Both Ca(OH)₂ and MTA were found to be clinically effective at 24 months posttreatment.

Can Dycal be used for direct pulp capping?

Dycal® Calcium Hydroxide Liner is a two-component, rigid-setting, self-curing material designed for use in direct and indirect pulp capping and as a protective liner under dental adhesives, varnishes, filling materials, cements, and other base materials.

Is Dycal calcium hydroxide?

Dycal is a self-set rigid dental cement based on calcium hydroxide. It is indicated for both direct and indirect pulp coating. Dycal from denstply forms a protective base under cements, restorative materials and other base materials, stimulating the formation of secondary dentin.

What is calcium hydroxide dental?

Abstract. Calcium hydroxide has a hard tissue inducing effect. It is a powder, that can be mixed with a physiological saline to a paste. The paste is highly alkaline with a pH 12.5 and its application to the pulp results in necrosis of the part of coronal pulp tissue shows no or only a milled inflammatory reaction.

What is calcium silicate used for?

Calcium silicate (Ca2SiO4), also known as calcium silicon oxide, is a product derived from limestone and diatomaceous earth, and is used in the pharmaceutical industry as an anticaking agent. Anti-caking agents absorb moisture and allow products to flow freely during the manufacturing process.

What is calcium silicate cement?

INTRODUCTION. Calcium silicate-based cements {mineral trioxide aggregate (MTA) lookalike materials} are cements or root canal sealers that have been made based on a composition of calcium and silicate.

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.

Can we do obturation with MTA?

It is clear that MTA resists bacterial leakage to a higher degree than gutta-percha and sealer when used as an obturation material. These findings also demonstrate that the placement of MTA is technique-sensitive, and protocols for proper obturation and condensation must be observed.

Do you cure MTA?

Light-curable and dual-cure MTA products contain resins which dilute and inhibit the MTA's bioactivity. Resins never cure 100%. Uncured resin leaves cytotoxic monomers in the MTA-resin matrix and in contact with the pulp. Resins shrink during curing; they are not dimensionally stable.

Why is Biodentine better than Dycal?

The results of the present study showed that pulps that were treated with Biodentine were essentially free of inflammation and led to the formation of a good quality bridge which was more predictable, uniform, thick, continuous, and completely sealed the pulp tissue in comparison to Dycal.

Do you etch before Dycal?

10 The loss of material from Dycal as a result of acid contact is generally regarded as disadvantageous. Therefore, etching procedure should be done before Dycal application.

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.

How long does MTA take 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 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.

How do you remove a set MTA?

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

Can MTA be used as a liner?

Liners and Pulp Capping Materials

4 While MTA has been shown to be a reliable pulp capping, dentin sealing material, and is biocompatible; its formulation and chemical curing make it a less efficient material to use routinely for restoration lining or pulp capping material.

What is MTA made of?

Mineral trioxide aggregate (MTA) is composed of Portland cement, with 4:1 addition of bismuth oxide added so that the material can be detected on a radiograph. The cement is made up of calcium, silicon and aluminium. The main constituent phases are tricalcium and dicalcium silicate and tricalcium aluminate.

What is MTA sealer?

MTA Bioseal is an endodontic root canal sealer based on Mineral Trioxide Aggregate. It is a double paste component that allows complete filling of all root canals including accessory and lateral ones.
