How do you apply a dental 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.
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.
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. Dycal by Denstply is used as a protective liner prior to an adhesive, varnish, cement, restorative material or any other base.
What are the clinical steps for placement of a calcium hydroxide liner?

- Moisten the prepared cavity. Using the cotton pliers, pick up a small cotton pellet, wet it and remove the excess water by squeezing it on the gauze.
- Dispense the pastes. Dispense the base first.
- Mix the Calcium Hydroxide.
- Place the cement.
- Allow the cement to set.
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.
Do you light cure Dycal?
Prisma VLC Dycal is a calcium hydroxide base/liner. It is a one component, rigid-setting, visible light cured material designed for use in direct and indirect pulp capping and as a protective base/liner under dental adhesives, varnishes, filling materials, cements, and other base materials.
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 Dycal be used under composite?
What is a disadvantage of calcium hydroxide as a lining material?
Calcium hydroxide has significant drawbacks; the low elastic modulus and low compressive strength of calcium hydroxide cavity liners restricts their usage to thin layers in specific areas, which is not critical to the support of restorations.
Is Dycal a base or liner?
Prisma VLC Dycal calcium hydroxide base/liner is a one-component, rigid-setting, visible light cured material designed for use in direct and indirect pulp capping and as a protective base/liner under dental adhesives, varnishes, filling materials, cements, and other base materials.
How do you use Dycal and composite?

How do you mix Dycal?
Dycal® Liner should be mixed in equal volumes (1.17 to 1.00 by weight) for optimum performance. The mixed material should be homogeneous and streak free prior to application. Variations may affect the radiopacity, strength, and durability of the material.
How do dentists mix calcium hydroxide?
Use a stirring motion to mix the two pastes together until a uniform color is achieved; this should not take more than 10-15 seconds. When finished mixing, wipe off the instrument and use the applicator to pick up a portion that is about the size of the prepared cavity.
What do you mix with calcium hydroxide powder?

Why is Dycal used for in dentistry?
Description: 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.
How long can you leave calcium hydroxide in a tooth?
Therefore, while calcium hydroxide is a very effective intra-canal medicament, it should be used with caution for periods longer than 1 month, especially in traumatized immature teeth with thin root walls, which are more prone to root fracture.
What is the difference between a cavity liner and a base?
Liners do not have the sufficient thickness, hardness, or strength to be used alone in a deep cavity, nor should they be used to achieve thermal protection or as a buildup material in a cavity preparation. In comparison, a base not only provides a barrier to chemical irritation, but can also provide thermal insulation.
What is the purpose of Dycal?
What are the dangers of calcium hydroxide?
Chronic exposure: Calcium hydroxide can cause chronic skin dermatitis, desquamation, vesiculation, and ulceration, as well as coughing, fluid in the lungs, and difficult breathing. WARNING! Transport victims immediately to emergency medical facility!
Do you etch before liner?
Where do we apply base in cavity?
A dental base is a material that is placed on the floor of the cavity preparation in a relatively thick layer. Its purpose is to protect the pulp by providing thermal insulation due to temperature changes and absorbing occlusal forces.
How long can calcium hydroxide stay in root canal?
Ca(OH)2 is a highly alkaline material (pH = 13) that alters the environment of the bacterial that causes root canal failures. The medicine is often left inside the tooth for 2-4 weeks to allow adequate time for the medicine to percolate to all fins, ledges, walls, and extra anatomy within the treated tooth.
What is the role of calcium hydroxide in dentistry?
Calcium hydroxide formulations are also used during treatment of root perforations, root fractures and root resorption and have a role in dental traumatology, for example, following tooth avulsion and luxation injuries.
What is difference between base and liner?
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 the difference between base and liner?
How is calcium hydroxide removed from root canal?
Intracanal calcium hydroxide is usually removed from the root canal by the use of copious manual irrigation with either sodium hypochlorite combined with hand instrumentation and a final rinse with EDTA.
What is the disadvantage of calcium hydroxide?
The creation of physiologic hard tissue barrier using calcium hydroxide has several disadvantages. The treatment requires multiple appointments and takes anywhere from 3 to 18 months. Additional negative factors are susceptibility to fracture,4 coronal microleakage and esthetic demands during the long term treatment.
