Can you use ZOE with composite?

Their conclusion was that the ZOE base affects the composite microhardness and elastic modulus to a distance of only 100 microns from the interface, and so it can be a suitable material to be used under modern composites.

Is zinc oxide-eugenol compatible with composite?

Zinc oxide–eugenol cements should be used with caution under resin-based composite restorations because the eugenol can inhibit the polymerization of the resin. A glass ionomer cement base may be placed over zinc oxide–eugenol before the placement of resin-based composite in order to avoid polymerization.

Why is zinc oxide-eugenol contraindicated under composite?

... 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.

What liner can be used under composite?

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.

What can we use under composite restoration?

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

ZINC OXIDE EUGENOL CEMENT | DENTAL CEMENTS | SUPER EASY

Can we use Dycal with 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.

What materials Cannot be used under a resin type restoration?

Answer: C. Zinc Oxide Eugenol. Reason: Residual free eugenol interferes with the proper setting of resin-based composites or resin cements.

What dental cement should never be used under a composite restoration?

Zinc oxide–eugenol cements should be used with caution under resin-based composite restorations because the eugenol can inhibit the polymerization of the resin.

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.

Why ZOE is not used as a base under composite?

One of the most accepted and indisputable statements in restorative dentistry is that cavity bases containing Zinc-Oxide-Eugenol (ZOE) have a negative effect on polymerization of conventional composites, yielding weaker restorations.

Why are eugenol based liners contraindicated when using composite restorations?

Eugenol used in cements for fixation of temporary restoration can penetrate into dentin and might affect adhesion of resin cements that are used for fixation of permanent restorations at a later stage.

Is ZOE and IRM the same thing?

IRM is an intermediate restorative material, composed of polymer reinforcement zinc oxide-eugenol (ZOE).

Can ZOE be used as a liner?

They are widely used as luting cements and can also be used as linings with adjustment of the powder/liquid ratio to change the consistency. However, they may have an irritant effect as a liner in deep cavities.

What is ZOE used for in dentistry?

use as dental cement

systems are zinc phosphate and zinc oxide-eugenol (ZOE). Zinc phosphate is typically used for permanent cementation, whereas ZOE is used for temporary cementation. Both can serve as insulating bases to protect tissues from heat or cold passing through highly conductive amalgam restorations.

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.

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.

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.

Does ZOE release fluoride?

The release of fluoride from eugenol can be explained from the setting reaction of ZOE cement. When eugenol is mixed with zinc oxide, a chelation reaction occurs and zinc eugenolate is formed.

Which cement is most irritating to the pulp?

Zinc phosphate cements

May irritate dental pulp, especially when used in cavity lining.

On what mixing surface is ZOE mixed?

On what mixing surface is ZOE mixed? oil-resistant paper pad or a glass slab.

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.

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.
