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.

What is pulpal protection?

Pulp capping is a dental procedure that prevents the tooth pulp from being exposed during a cavity preparation, hence preventing the need for a root canal procedure.

What liner protects the pulp?

4,9 A variety of dental materials have been introduced as liners to provide pulp tissue protection from irritants related to the restorative procedure. The traditional lining materials include calcium hydroxide, glass ionomer, and resin-modified glass ionomers (RMGIs).

What material is used for pulp capping?

Two types of pulp-capping materials, calcium hydroxide and mineral trioxide aggregate, have been most commonly used in clinics, and an adhesive resin has been considered a promising capping material.

Why do we need Pulp protection?

Protecting the pulp is essential when it is exposed in preparations to prevent pain, infection, and the eventual loss of the tooth. Pulp capping can help, which involves sealing materials over the exposure to protect the pulp. There are many options for pulp capping in restorations.

Pulp Protection Simplified | Varnish | Part 1

What are the different classifications of pulp protection?

Two different types of pulp cap are distinguished. 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.

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 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.

Why do we use Dycal?

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 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 we use Dycal under GIC?

CaOH under GIC is redundant and counterproductive. One is placing a hard compressive strength materiral (GIC) on a softer one (Dycal). The rate of reparative dentin is constant and is not determined by the use of Dycal.

What is Dycal composition?

Dycal® is a paste-paste calcium hydroxide dental cement uses as pulp capping and liner in dentistry. First paste (base paste) contains titanium dioxide and barium sulphate in glycol disalicylate and second paste (catalyst paste) contains calcium hydroxide, zinc oxide and zinc stearate in ethyl toluene sulphonamide.

How can pulp be protected when using a composite restorative material?

This light-cured resin modified calcium silicate material uses a hydrophilic resin matrix which allows for the significant release of calcium and hydroxide ions to aid in pulp tissue therapy. Since it is resin based and light-cured, it is an easy solution for pulp protection under all composite restorations.

How does Dycal work?

Our results evidence that pulp capping with Dycal, as well as with Hydrogel, stimulates the formation of reactionary dentin at the periphery of the pulp chamber. Dycal contributes to the partial closure of the pulp exposure, producing a defective reparative dentinal bridge.

How do you control pulp exposure?

Pulp exposures can be managed conservatively through vital pulp treatment procedures such as pulp-capping and pulpotomy, which utilize the regenerative capacity of the pulp.

What is Formocresol used for?

Formocresol is a mixture consisting of formalin, cresol and glycerine used in dentistry. It is used for vital pulpotomy of primary teeth and as a temporary intracanal medicament during root canal therapy.

Is Dycal the same as 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.

Can you use Dycal and Vitrebond together?

Both studies demonstrated that the pulp–dentin complex response to Vitrebond and Dycal indicated acceptable biocompatibility of these materials and there are no statistically significant difference between calcium hydroxide and Resin-Modified Glass Ionomer.

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.

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.

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.

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.

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.
