What is Dycal used for?

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.

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.

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 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.

Can Dycal 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.

Can Dycal be used as a cement?

Materials based on zinc oxide eugenol, zinc phosphate, zinc polycarboxylate (ZPC), glass ionomers (GI), or resin can be used as final cements. 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.

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.

What is the pH of Dycal?

between 9.80 to 10.86
The pH of Dycal ® and PCFA ranged between 9.80 to 10.86 and 10.57 to 11.72, respectively.

How long can calcium hydroxide stay in root canal?

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.

How long should calcium hydroxide be left in a root canal?

The duration of dressing with calcium hydroxide is dependent upon the objective of dressing. If used as a routine antibacterial dressing, then 7 days are sufficient. If the objective is to arrest a weeping canal, then it may be necessary to dress with a stiffer paste for a period of at least 14 days.

What is 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.

Does Vitrebond need etch?

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.

When should I use Vitrebond?

Due to its adhesion to set amalgam and its superior masking qualities, Vitrebond is useful as an adhesive masking agent on amalgam with esthetically disturbing surfaces. Several reports support the use of Vitrebond for interim restoration of decayed deciduous and permanent teeth.

What is the critical pH of enamel?

In relation to caries, with the calcium and phosphate concentrations in plaque fluid, the ‘critical pH’ below which enamel dissolves is about 5.5.

What is the critical pH of dentine?

Root dentin is vulnerable to acidic dissolution than enamel because of its higher critical pH for demineralization (6.2 – 6.4) than that of enamel (5.5).

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.

Is calcium hydroxide harmful?

Are there any risks associated with it? Food-grade calcium hydroxide is generally safe. However, if you work with industrial-grade calcium hydroxide, ingesting it can result in calcium hydroxide poisoning. This can lead to severe injury or death.

How long can calcium hydroxide stay in tooth?

Can I use Dycal under composite?

What is dycal made out of?

Dycal® Liner Base paste: disalicylate ester of 1,3, butylene glycol; calcium phosphate; calcium tungstate; zinc oxide; iron oxide Dycal® Liner Catalyst paste: calcium hydroxide; ethyl toluenesulfonamide; zinc sterate; titanium dioxide; zinc oxide; iron oxide.

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?

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. Do not take internally.
