TheraCal PT and TheraCal LC – is there a reason to have both?
TheraCal PT is not intended to replace TheraCal LC.
TheraCal PT and TheraCal LC share some of the same indications for use, however we recommend you use TheraCal PT for pulpotomies and continue to use TheraCal LC as a liner and for direct and indirect pulp capping. This approach is more cost effective based on the number of applications from 1 box of TheraCal LC (4 - 1g syringes = 40-50 uses depending on application/s) verses TheraCal PT's 1 - 4g syringe (approximately 12 - 15 pulpotomy applications).
What are the indications for TheraCal PT?
Primary indication: Pulpotomies
TheraCal PT can also be used for pulp capping, and as a liner or base.
What is the shelf life of TheraCal PT?
18 Months. TheraCal PT syringe is pouched and should remain so until ready to use. Once pouch is opened, use TheraCal PT within 90 days.
What is the storage for TheraCal PT?
TheraCal PT should be stored at room temperature (68°-77° F; 20°-25° C)
What is the working time?
Minimum of 45 seconds
What is the setting time?
Maximum of 5 minutes
How many applications can you get out of the 4g syringe of TheraCal PT?
Approximately 12 – 15 pulpotomy applications
What is the color of TheraCal PT?
A1/Natural
Do you need to place a bonding agent first?
No. Achieve hemostasis, place TheraCal PT, light-cure for 10 seconds and place desired adhesive, base, and/or restoration following manufacturer’s directions for restoring tooth.
What is the difference between TheraCal PT and Calcium Hydroxide?
One of the known limitations of calcium hydroxide-based materials is their relatively high solubility, which leads to dissolution of the material over time. TheraCal PT is moisture tolerant and will not wash out.
What are the differences and similarities between TheraCal PT and Mineral Trioxide Aggregate (MTA) material?
TheraCal PT is a resin-modified calcium tri-silicate that has enhanced physical properties when compared to MTA material. Essentially, the primary chemical used in both materials are similar but TheraCal PT contains a unique hydrophilic resin, which facilitates calcium release. Similar to MTA material, TheraCal PT has an alkaline pH.
Can disinfectants, desensitizers or wetting agents (i.e. Chlorohexidine, Gluma, Sodium Hypochlorite) be used prior to placing TheraCal PT?
Yes, after hemostatsis, disinfectants, desensitizers or wetting agents can be used.
Please note per the instructions for use: when chlorohexidine and sodium hypochlorite are used together staining may occur. If used together there should be a saline rinse in between.
Does Theracal PT have the same viscosity as TheraCal LC?
No. TheraCal PT is more viscous.
How are TheraCal PT and TheraCal LC different and/or alike?
Unlike TheraCal LC, TheraCal PT is a dual-cured material indicated for pulpotomies. TheraCal PT and LC both use THERA technology which is a unique hydrophilic resin matrix that facilitates calcium release. PT and LC are both radiopaque, moisture tolerant and offer an alkaline pH.
