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 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.

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.

Which base is contraindicated under composite resins?

... Traditional base materials, such as zinc oxide-eugenol cements, have been contraindicated for composite restorations due to inhibition of resin polymerization by the phenolic hydrogen of eugenol.

TheraCal LC as a liner in a Class II resin based composite restoration

What is the best base under composite?

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

Is Dycal a liner or base?

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 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.

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.

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 calcium hydroxide a base or liner?

Calcium hydroxide is a low strength base that can be used as a liner, intermediary base or pulp-capping agent.

Why is a lining used under a filling?

Dental cavity liners have historically been used to protect the pulp from the toxic effects of some dental restorative materials and to prevent the pain of thermal conductivity by placing an insulating layer between restorative material and the remaining tooth structure.

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.

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.

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.

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.

Can varnish be placed under all restorative materials if not with which materials is it contraindicated?

Can varnish be placed under all restorative materials? If not, with which materials is it contraindicated? NO, because dental varnish interferes with the bonding and setting reaction of composite resins and glass ionomer restorations the use of varnish is contraindicated with these materials.

Does composite bond to Vitrebond?

Vitrebond requires application of a separate bonding agent to adhere composite to Vitrebond. The adhesion between composite and Vitrebond is found to be high with and without an separate acid etching.

Is Vitrebond a liner or base?

Vitrebond™ is a light-cured, resin-modified glass ionomer (RMGI) liner/base material. It is recommended for use as a liner or base under composite, amalgam, metal and ceramic restorations.

Do you etch after Vitrebond?

Vitrebond Plus liner/base can be used with any type of adhesive (light or self cured; separate etch or self-etch, i.e. - 4th, 5th or 6th generation adhesives) on dentin or enamel.

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.

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.
