What is Dycal composition?

Dycal® is two-paste calcium hydroxide compounds that consist of a base containing titanium dioxide in a glycolsalicylate and a catalyst containing calcium hydroxide and zinc oxide in ethyl toluensulfon- amide.

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.

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 is the purpose of 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.

Can dycal be used as root canal sealer?

Dycal was used in combination with gutta-percha points for the filling of root canals of single-rooted teeth. Results showed good adaptation in the dentine wall-gutta-percha cone interphase; Dycal was well tolerated by the apical and periapical tissues and gave little or no postoperative discomfort.

What are the disadvantages of using calcium hydroxide in dentistry?

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.

How long can you leave calcium hydroxide in a tooth?

Calcium hydroxide retains its anti-bacterial properties for about two months when placed under a restoration, after which it degrades to calcium oxide and other less effective calcium salts.

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.

Can Dycal be used as a base?

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.

What is the benefit of calcium hydroxide Dycal liner?

Dycal® Calcium Hydroxide is a radiopaque material used worldwide for cavity lining and pulp capping. Its system prevents small variations in the base to catalyst ratio, affecting the working and setting times of the material.

What is the disadvantage of calcium hydroxide liner?

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.

What are alternatives to Dycal?

JOY-Cal is a radiopaque calcium hydroxide liner product like Dycal®. It is a self-setting cavity liner and pulp capping agent, and it insulates the dentin and pulp from acids found in certain restoratives and cements.

Why should calcium hydroxide not be used excessively?

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!

Which is better pulp capping 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.

Which is better calcium carbonate or calcium hydroxide?

The important difference between calcium hydroxide and carbonate is also their solubility in water. Calcium carbonate is practically insoluble in water (0.013 g L⁻¹ at 25 °C), while calcium hydroxide is more soluble (1.59 g L⁻¹ of saturated solution at 25 °C) [39, 40].

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 are contraindications of Dycal?

When Should Dycal not be taken? (Contraindications) Contraindicated to patients with increased calcium level in blood and/or increased calcium in urine, kidney stone, increased level of vitamin D, and phosphate in blood.

How do you use Dycal under composite?

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 amalgam?

Castle says that 'DYCAL is not able to withstand the condensation pressure of packing the amalgam'.

Do you etch and bond 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.

What is the best base under composite?

A suitable base material for composite resin restorations: zinc oxide eugenol.

Does calcium hydroxide cause root resorption?

However, the usage of calcium hydroxide is not routinely recommended for primary dentition because its application frequently results in the development of chronic pulpal inflammation and internal root resorption.

Does calcium hydroxide cause pulp necrosis?

The initial effect of calcium hydroxide applied to exposed pulp is the development of a superficial three-layer necrosis. The beneficial effect of calcium hydroxide is regarded as the result of the chemical injury caused by the hydroxyl ions.

Does calcium hydroxide affect bone?

These results clearly indicate that skeletal unloading-induced disorder of bone metabolism is partly prevented by oral administration of calcium hydroxide. Calcium ingestion may be useful as a therapeutic tool in the disorder of bone metabolism caused by skeletal unloading.
