What is TheraCal LC used for?
TheraCal LC is a single paste calcium silicate-based material promoted by the manufacturer for use as a pulp capping agent and as a protective liner for use with restorative materials, cement, or other base materials.
What is dental TheraCal?
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. TheraCal LC performs as a barrier and protectant of the dental pulpal complex.
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).
How do you use TheraCal?
Apply TheraCal LC directly to the exposed pulp in incremental layers. Layer is not to exceed 1 mm in depth. Cover all the exposed areas and extend TheraCal LC at least 1 mm onto sound dentin surrounding the exposure. Light cure between layers.
What is LC in dental?
TheraCal LC is a light-cured, resin-modified calcium silicate material that performs as a barrier and protectant to the dental pulpal complex. It is indicated for direct and indirect pulp capping and as a protective base/liner under restorative materials including composite, amalgam and cements.
What is calcium hydroxide dental?
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.
Does TheraCal release fluoride?
TheraBase is a dual-cured, calcium and fluoride-releasing material indicated for base restorations. TheraCal LC may also be used as a base but needs to be placed in 1 mm increments and light-cured between layers.
Do you cure TheraCal?
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 MTA in dentistry?
Abstract. Mineral trioxide aggregate (MTA), composed mainly of tricalcic silicate, tricalcic alluminate, bismuth oxide, is a particular endodontic cement. It is made of hydrophilic fine particles that harden in the presence of dampness or blood.
Why do dentists use calcium hydroxide?
Calcium hydroxide may be used to preserve the vital pulp if infection and bleeding are controlled; to repair root fractures, perforations, open apices and root resorptions. Endo-perio lesions are complex and the correct diagnosis is essential if treatment is to be successful.
Is calcium hydroxide bad?
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.
What is the mechanism of action of TheraCal LC?
TheraCal LC may act as a scaffold for reparative dentin formation. Dentinal fluids are absorbed within it, resulting in the release of calcium and hydroxide ions, and the tooth responds to form apatite and a bond, supporting the natural sealing ability of the product.
