Dycal® Calcium Hydroxide Liner is a two-component, rigid-setting, self-curing material designed for use in direct and indirect 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.

and as a protective liner under dental adhesives, varnishes, filling materials, cements, and other base materials.

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.

When would you use calcium hydroxide liner?

Calcium hydroxide liners are used for its bioinductive and antimicrobial activity. It should be only used in the deepest spots in the cavity where the RDT is ≤0.5 mm. The placement of calcium hydroxide should be followed by a layer of RMGI to protect it from its drawbacks.

Can you use Dycal under composite?

Further studies are necessary to suggest that Dycal can be used without any inhibitions under composite resin restorations, may be in vivo studies with long-term follow-up of the outcome are required.

Where is Dycal placed?

1.6. Using the ball-pointed Dycal® Liner applicator or similar instrument, place the mix directly on the exposed pulp and cavity dentin judged to be less than 1.0mm remaining thickness in a thin layer. Avoid placing Dycal® Liner on enamel or the margins of the cavity. Avoid placing a large bulk of material.

How to mix and apply Dycal in deep cavities - DENTALKART

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.

When should I use pulp capping?

Direct pulp capping should be used only on a vital pulp that has been accidentally injured and shows no other symptoms. Direct pulp capping should not be performed on a pulp that has been exposed as a result of penetrating caries. A successful pulp cap has a vital pulp and a dentin bridge within 75 to 90 days.

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.

What is considered the best pulp protection?

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 the primary purpose of calcium hydroxide?

What is the primary purpose for placing calcium hydroxide? To promote reparative dentin as a barrier between pulp and restoration.

On what tooth structure is calcium hydroxide placed?

As shown, calcium hydroxide is placed over the deepest portion of the pulpal floor, and only on dentin.

Would cavity varnish be placed under or over calcium hydroxide?

Be sure that if calcium hydroxide is indicated, it is placed prior to cavity varnish, and is set before applying the varnish. 4.

Do you etch before or after liner?

If an RMGI base or liner is to be used, it should be placed and cured before the etching or adhesive steps. For details regarding specifics of adhesive systems, refer to Chapter 40. The preparation should be etched for 15 to 20 seconds with an acid gel.

Can calcium hydroxide be used under composite?

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.

Does Vitrebond need etch?

Use Vitrebond Plus for the initial cervical portion of Class V restorations. It adheres to dentin without phosphoric acid etching while providing fluoride release for future caries control and a dentin shade for esthetics.

Why is a liner used under a filling?

Since the 19th century liners have often been placed in cavities in the teeth under the filling material. The liners are thought to protect the living pulp of the tooth from filling materials themselves and also from their potential to allow more heat or cold through than the natural tooth would.

Can Dycal be used as a cement?

Materials based on zinc oxide eugenol, zinc phosphate, zinc polycarboxylate (ZPC), glass ionomers (GI), or resin can be used as final cements. Calcium hydroxide (Dycal by Dentsply Caulk and Nu-cap by GC America) is a material that generally is not thought of as a temporary cement.

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 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.

When is Dycal used in dentistry?

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 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.

How do you stop pulp from bleeding?

Sodium hypochlorite (NaOCl) at a concentration of 5% can be applied for 30 seconds to stop bleeding as shown by Dammaschke et al. (13) and Asgary et al. (14). In addition, NaOCl demonstrated moderate/high rate of pulp survival.

Why Vaseline is applied over GIC?

Similarly petroleum jelly also impedes the fluoride release, but to a very less extent. We suggest that in situations where the fluoride release property is more important than other properties it is better to coat the GIC with petroleum jelly or leave the restoration without any coating.
