How do dentists mix calcium hydroxide?

Mix the Calcium Hydroxide. Use a stirring motion to mix the two pastes together until a uniform color is achieved; this should not take more than 10-15 seconds. When finished mixing, wipe off the instrument and use the applicator to pick up a portion that is about the size of the prepared cavity.

How do you mix calcium hydroxide powder in dentistry?

Prepare a moderately stiff paste by mixing Calcium Hydroxide Powder with sterile water. 4. Introduce the paste into the canal, packing the paste against the periapical tissue. Close the tooth with a temporary filling material and recall the patient in 2 weeks.

How is calcium hydroxide used in dental?

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.

How do you put calcium hydroxide in a root canal?

Youtube quote:And once it is in the middle of coronal third you use the needle to carry it deeper into the canal. So you inject a little bit in the middle coronal third and then push it deeper.

How do you mix Dycal dental?

Dispense equal volumes of base and catalyst pastes on the parchment paper pad provided. Replace container caps. Using a Dycal® Liner applicator, stir immediately to mix thoroughly until a uniform color is achieved. Do not over-spatulate.

How do you mix calcium hydroxide?

Mix the Calcium Hydroxide.



Either the calcium applicator or the spoon excavator can be used for mixing. Use a stirring motion to mix the two pastes together until a uniform color is achieved; this should not take more than 10-15 seconds.

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

After thorough cleaning of the root canal, the calcium hydroxide is left for longer periods of time to give the root development a chance to continue. The intracanal medicament is usually changed after one month. After that, it is left for at least 6 months when a radiographic check-up is done.

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.

How long can you leave calcium hydroxide in a tooth?

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 does it take calcium hydroxide to work?

Analyzing the pH and the concentration of calcium ions in the periapical area, it is obvious that at least 2 weeks are necessary for calcium hydroxide bactericide activity.

Is Dycal the same as calcium hydroxide?

Dycal Calcium Hydroxide Dental Cement



Description: Dycal is a self-set rigid dental cement based on calcium hydroxide. It is indicated for both direct and indirect pulp coating.

When should calcium hydroxide be set?

Calcium hydroxide cements are used for lining specific areas of deep cavities or for direct pulp capping. The antibacterial action of calcium hydroxide makes these cements useful in indirect pulp-capping procedures involving carious dentin.

What is the difference between Dycal and TheraCal?

TheraCal LC secures a protective physical lining despite contact with dentinal or pulpal fluids. Its solubility is lower than that of Dycal, ProRoot MTA, Angelus MTA, and Biodentine [21, 22], and its water sorption and porosity is similar to ProRoot MTA and Biodentine, and lower than Angelus MTA [21].

Do you etch before TheraCal?

Cover all moist effected surfaces with TheraCal LC, light-cure, and proceed with the bonding procedure (Figure 1). The tooth is then etched with either a total-etch or selective phosphoric-acid technique. A bonding agent is then used before seating the restoration (Figure 2).

What is TheraCal used for?

Description. TheraCal LC is a light-cured, resin-modified calcium silicate filled liner designed for use in direct and indirect pulp capping and as a protective liner under composites, amalgams, cements, and other base materials.

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.

Do you cure Dycal?

Prisma VLC Dycal calcium hydroxide base/liner 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.

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.

Is Dycal a base or liner?

Dycal is a calcium hydroxide rigid-setting material for direct and indirect pulp capping, and a protective liner under dental filling materials, cements and other base materials.

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.

When would you use calcium hydroxide liner?

Calcium hydroxide liners are used for its bioinductive and antimicrobial activity. It should be only used in the deepest spots in the cavity where the RDT is ≤0.5 mm. The placement of calcium hydroxide should be followed by a layer of RMGI to protect it from its drawbacks.

Does Dycal release fluoride?

Dycal is a calcium hydroxide liner that works as well. Vitrebond is nice because of the fluoride releasing property. This should help with sensitivity. This can be used as an indirect pulp cap, if deep and not pulp exposure is noted, or as a direct pulp cap if there is a slight exposure of the pulp horn.

How do you know if pulp capping is successful?

Indication for Direct Pulp Capping:

  1. Immature/mature permanent teeth with simple restoration needs.
  2. Recent trauma less than 24hours exposure of pulp / mechanical trauma exposure (during restorative procedure)
  3. Minimal or no bleeding at exposure site.
  4. Normal sensibility test.
  5. Not tender to percussion.

Do you etch before 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.

On what tooth structure is calcium hydroxide placed?

21 Cards in this Set

silver, tin, copper, zinc makeup of the alloy powder in amalgam
tooth structure that calcium hydroxide is placed dentin
unique characteristics of calcium hydroxide protects the tooth from chemical irritation produces reparative dentin compatible with all restorative materials

What can happen if you desiccate the dentin during a dental procedure?

If a tooth were to be desiccated during this process, you only leave dentinal tubules and virtually nothing for the resin to flow into, basically diminishing the entire hybrid zone.

What is the main ingredient in dental varnish?

What is the main ingredient in varnish? The main ingredient is flouride. The varnish is a gel-like substance that was designed to released fluoride on enamel, root structure, and dentin structure.
