How long does it take for dycal to set?
Allow the Dycal® Liner to completely set. The mixed material will set in approximately 2-3 minutes on the mixing pad under normal room conditions (70°F with 50% relative humidity). Set time is shorter in the mouth due to moisture and temperature.
What are the side effects of dycal liners?
Avoid prolonged or repeated exposure of the Dycal®Liner material with skin, oral soft tissues, and eyes. Irritation and possible corneal damage may result. Skin rash, oral mucosa irritation, or other allergic reactions (allergic contact dermatitis) may result in susceptible individuals.
Does calcium hydroxide cure light?
Calcium hydroxide cements are supplied in a visible light–cured system (Fig. 21.1A) and a two-paste system (Fig. 21.1B).
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.
Do you etch after 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 difference between Dycal and 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.
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.
Can Dycal be used 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 Dycal a temporary cement?
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 a base or liner?
Dycal radiopaque calcium hydroxide composition is a rigid, self-setting material useful in pulp-capping, and as a protective base/liner under dental filling materials.
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.
What can I use instead of 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.
What is another name for Dycal?
Intervention: drug: Dycal, Other names: Calcium Hydroxide.
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.
What is non setting 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.
What is calcium hydroxide Dycal?
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.
Is Dycal a base or liner?
Dycal radiopaque calcium hydroxide composition is a rigid, self-setting material useful in pulp-capping, and as a protective base/liner under dental filling materials.
What is hard setting calcium hydroxide?
Calcium hydroxide has a hard tissue inducing effect. It is a powder, that can be mixed with a physiological saline to a paste. The paste is highly alkaline with a pH 12.5 and its application to the pulp results in necrosis of the part of coronal pulp tissue shows no or only a milled inflammatory reaction.
What is a dycal?

What is calcium hydroxylide liner?
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. It will not inhibit the polymerization of acrylic and composite restorations.
What is the best way to protect against needles odontoblast injury?
Due to their alkaline nature, they also serve as a protective barrier against irritants from other restorative materials; using calcium hydroxide liners under RMGI is the best way of avoiding needles odontoblas t injury that might result from applying RMGI in deep cavities.53Calcium hydroxide liners are also recommended as a protective layer “subbase” beneath a ZOE temporary restoration.54Similarly, in deep cavities with minimal remaining dentine covering the pulp, calcium hydroxide liners are recommended as a protective layer under zinc phosphate cements – to help reduce the effects of the initial low pH (4.2 at 3 minutes).55
What is a cavity lining?
The definition of liners itself has been a source of confusion in dental literature. Marzouk et al13defined cavity liners as film-forming materials that carry therapeutic agents , which create their greater film thickness (up to 25 µm) and usually applied to dentine only. Ferracane14described a liner as material that is applied in a thin layer to seal the dentine on the floor and walls of the cavity against the influx of bacteria or irritants from restorative procedures. In 1994, The Journal of Operative Dentistrypublished a letter submitted by Summit15in which he enlisted cavity liners, varnishes, and resin-bonding agents as subcategories of cavity sealers. He proposed a definition of a cavity liner as a cement or resin coating with minimal thickness (usually <0.5 mm) to achieve a physical barrier to bacteria or a therapeutic effect (a chemical effect which in some way benefits the health of the pulp of the tooth). Later on, McCoy16submitted a letter to The Journal of Operative Dentistryin which he made changes to the original definitions and structure (based on the feedback from Operative Dentistryreaders) previously made by Summitt.15McCoy stated that pulp protection materials should be classified into categories based on an increase in thickness and viscosity. Hence, liners were categorized in a separate category and maintained the same definition previously proposed by Summitt. Hilton6defined cavity liners as materials placed with minimal thickness (usually <0.5 mm), which act as cavity sealers and provide expanded beneficial functions, such as fluoride release, adhesion to tooth structure, and/or antibacterial action that promotes the health of the pulp. Ten years later, Hilton17defined cavity liner as cement or resin coating of minimal thickness (≤0.5 mm) that acts as a barrier to bacteria, as well as typically providing a therapeutic effect, such as an antibacterial or pulpal anodyne effect. They added that the placement of the liner is often, but not always, limited to the dentine closest to the pulp. Qualtrough et al1defined a cavity liner as an aqueous or volatile organic suspension or dispersion of zinc oxide or calcium hydroxide that can be applied to a cavity surface in a relatively thin film. They included glass ionomer and RMGI cements as materials suitable for use as lining materials. Weiner18defined a cavity liner as a thin layer of material (0.5 mm) placed on the surface of the tooth preparation that, in part, protects the tooth from the restorative material, intra-oral fluids, and ultimately from the outside environment but usually do not have sufficient thickness, hardness, or strength to be used alone in a deep cavity. Similarly, Heymann et al3defined liners as suspensions or dispersions of zinc oxide, calcium hydroxide, or RMGI that can be applied to a tooth surface in a relatively thin film. Anusavice et al19stated that a cavity liner is a material that is used to coat the bottom of a prepared cavity to protect the pulp; it is applied in a thin layer and usually contains calcium hydroxide or mineral trioxide aggregate (MTA); it also includes certain glass ionomer cements used as intermediate layers between tooth structure and composite restorative material.
What are the drawbacks of calcium hydroxide?
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.31,38Calcium hydroxide liners have low thermal conductivity, but they are usually not used in thick enough layers (≤0.5 mm) to provide thermal protection;20therefore, thermal protection should be provided with a separate base. Hence, it is recommended that they should be only applied over the smallest area that would suffice to aid in pulp therapy.2Calcium hydroxide liners must not be left on the margin of the prepared cavity or the margin will not be properly sealed because the liner is soluble in water.19It has high solubility and water sorption,39which may result in softening of the liner and in material loss under poorly sealed tooth–restoration interface where the oral fluids can penetrate through and partially or totally dissolve this pulp-protecting material.9This was previously described in the literature as the “Disappearing Dycal” syndrome.7Calcium 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.40,41Phillips et al40reported that the solubility of calcium hydroxide (paste/paste) liners in phosphoric acid (37%) varies markedly among brands and it is dependent on the commercial preparation. The same study also reported that solubility of calcium hydroxide might be sensitive increase in base/catalyst ratio.
What are the antimicrobial properties of calcium hydroxide?
Calcium hydroxide liners are reported to display antibacterial properties.33The antimicrobial properties of calcium hydroxide come from its dissociation into calcium and hydroxyl ions. The hydroxyl ions create an alkaline pH that is unfavorable for remaining bacteria in the cavity.
Where to use calcium hydroxide liners?
This review underlines the fact that calcium hydroxide liners should only be used in the deepest spots in the cavity where the remaining dentine thickness is ≤0.5 mm. A protective layer of resin-modified glass ionomer should always follow the application of calcium hydroxide liners.
What is a suspension lining?
Liners (previously referred to as low-strength bases or cement liners or subbases) are materials placed in deep portions of the cavity preparations that harden when mixed to form a cement layer (100–500 µm) usually with minimum strength and low rigidity functioning as a barrier to irritating chemicals and providing therapeutic benefit to the pulp. Suspension liners are set by physical means (drying) and upon the evaporation of the volatile solvent form a relatively thin film (20–25 µm) that serves as a protective barrier between dentine and the restorative material and provides some therapeutic effect and provide no mechanical strength, no thermal insulation, and should only be used to line dentine.
What is the purpose of operative dentistry?
One of the aims of operative dentistry is to preserve the pulp vitality in compromised teeth: one method used for this reason is the use of liners and bases. This involves the placement of protective materials on the unexposed pulp to maintain its health and to stimulate defensive repair by tertiary dentine deposition.
