What is the minimum thickness for the placement of MTA for a direct pulp cap?

success, MTA results in more predictable dentin bridging and pulp health. 96 MTA (at least 1.5 mm thick) should cover the exposure and surrounding dentin followed by a layer of light cured resin-modified glass ionomer.

Can MTA be used for direct pulp cap?

MTA was found to be as clinically successful as calcium hydroxide when used for direct pulp capping in both human primary teeth and third molars [7,8].

What is the thickness of the MTA layer used in primary molar pulpotomy?

The increments of MTA should be compacted against the floor and walls of the chamber using a cotton pellet moistened with sterile water. 16 The thickness of the compacted bulk of material should be 3–4 mm and should cover all of the root canal orifices and the floor.

What is used for direct pulp capping?

Calcium hydroxide remains the “gold standard” for direct pulp capping. It has the longest track record of clinical success, is the most cost-effective and is the likely effective component in MTA. Provide a well-sealed restoration immediately after pulp capping.

What is MTA pulp therapy?

MTA was used as pulp-capping material after partial pulpotomy to preserve the vitality of the pulpal tissues in two cases. Follow-up examinations revealed that the treatment was successful in preserving pulpal vitality and continued development of the tooth.

Biodentine Direct Pulp Cap

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.

Can MTA be used for pulpotomy?

MTA may be used as an alternative pulpotomy agent in immature teeth with pulp exposure to stimulate pulp healing with dentin bridge formation and complete root formation. But, discoloration following MTA pulpotomy appears as a major clinical complication.

How is direct pulp capping done?

In direct pulp capping, the protective dressing is placed directly over an exposed pulp; and in indirect pulp capping, a thin layer of softened dentin, that if removed would expose the pulp, is left in place and the protective dressing is placed on top.

When is direct pulp capping done?

Direct pulp capping is used when the pulp is visibly exposed (vital pulp exposure) due to caries, trauma, or iatrogenic insult such as accidental exposure during tooth preparation or caries removal.

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 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.

What is pulp capping and pulpotomy?

Pulp Capping is an operative technique designed to preserve the vitality of a potentially infected pulp. Pulp capping offers an alternative to root canal treatments. If the pulp becomes infected and the tooth dies, a root canal will be needed to save it from a tooth extraction.

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.

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.

What is Apexogenesis and Apexification?

Apexification is a method of inducing a calcified barrier at the apex of a nonvital tooth with incomplete root formation. Apexogenesis refers to a vital pulp therapy procedure performed to encourage physiological development and formation of the root end.

Why is there no direct pulp capping in primary teeth?

One such vital pulp therapy procedure is direct pulp capping (DPC), which has been literally abolished from the repertoire of therapeutic procedures for primary teeth. DPC in primary teeth has had limited application due to dwindling success rates.

Is pulp capping necessary?

Pulp-capping procedures are a critical cornerstone of our philosophy of minimally invasive dentistry. Not every tooth that has symptoms of sensitivity, pain or deep lesions needs the root canal therapy that is often ordered by the dentist.

Why is formocresol used in pulpotomy?

Formocresol and ferric sulfate have been used as protective medicaments for partial or complete pulpotomy procedures, among other techniques, including electrosurgery and laser cautery. Ferric sulfate and formocresol staunch the bleeding pulp, but neither material is bioactive.

When do you use indirect pulp capping?

Indirect pulp capping occurs when the pulp tissue is close to the surface but not completely exposed. It usually includes two treatments spaced six to eight months apart. The indirect pulp capping procedure involves: Removing decay.

What can be used instead of formocresol?

Calcium phosphate cement as an alternative for formocresol in primary teeth pulpotomies. Indian J Dent Res. Jul-Aug 2013;24(4):522. doi: 10.4103/0970-9290.118370.

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.

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.
