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.

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.

What are the clinical steps for placement of a calcium hydroxide liner?

Can you etch calcium hydroxide?

7 Calcium hydroxide liners should not be acid etched as it might be softened and smeared over the walls of the cavity, which may contaminate acid-etched enamel and produce an inferior bond.

Do you etch before TheraCal?

Cover all moist effected surfaces with TheraCal LC, light-cure, and proceed with the bonding procedure (Figure 1). The tooth is then etched with either a total-etch or selective phosphoric-acid technique. A bonding agent is then used before seating the restoration (Figure 2).

Dycal

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.

Is TheraCal base or liner?

TheraCal LC is a light-cured, resin-modified calcium silicate filled liner designed for use in direct and indirect pulp cap- ping, as a protective base/liner under composites, amalgams, cements, and other base materials.

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.

How do you place a Dycal?

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.

Can you 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 calcium hydroxide be set?

Calcium hydroxide is used in both the preservation of the vital pulp and the disinfection of the prepared root canal system. To achieve success in direct pulp capping a strict aseptic regime must be followed. Various forms of root resorption, their aetiology and treatment, are considered.

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.

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.

Can calcium hydroxide be used under composite?

Studies have shown that calcium hydroxide “softens” under amalgam and resin-based composite restorations. The results are attributed to hydrolysis of the calcium hydroxide by fluid contamination from dentinal tubules and microleakage.

What lining can be used under a composite filling?

In our practice, we have traditionally used resin modified glass ionomer (RMGI) liner/bases for deep cavities and composite procedures. By their nature, RMGI liners are typically fluid materials that can adapt more readily to the internal aspects of a cavity preparation.

When do you use non calcium hydroxide?

Premixed non-setting calcium hydroxide is frequently used as interim root canal dressing in endodontically involved permanent teeth and as obturating paste in deciduous teeth in pediatric dentistry.

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.

Is Dycal setting or non setting calcium hydroxide?

Dycal is a rigid, but self-adjusting self-setting calcium hydroxide based dental cement. It is indicated for both direct and indirect pulp capping.

When should I use pulp capping?

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.

How do you put TheraCal?

Apply TheraCal LC directly to the exposed pulp in incremental layers. Layer is not to exceed 1 mm in depth. Cover all the exposed areas and extend TheraCal LC at least 1 mm onto sound dentin surrounding the exposure. Light cure between layers.

Can TheraCal be used for Pulpotomy?

TheraCal PT is a biocompatible, dual-cured, resin-modified calcium silicate designed for pulpotomy treatment. TheraCal PT maintains tooth vitality by performing as a barrier and protectant of the dental pulpal complex.

Is TheraCal a RMGI?

The light-cured, resin-modified calcium silicate filled material is an alternative to calcium hydroxide, glass ionomer, RMGI, IRM/ZOE, and other restorative materials. TheraCal LC exhibits several properties to help maintain ideal hard-tissue health and to reduce the incidence of postoperative sensitivity.

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 protect pulp from composite restoration?

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.
