Dual-Cured, Calcium and Fluoride-Releasing, Self-Adhesive Base/Liner

TheraBase is a dual-cure, calcium and fluoride-releasing, self-adhesive base/liner. Utilizing the THERA technology, TheraBase chemically bonds to tooth structure, and releases and recharges calcium and fluoride ions.1 TheraBase’s calcium release generates an alkaline PH* which promotes pulp vitality.2 It is a dual-cured material that will polymerize even in deep restorations where light cannot reach.

TheraBase is stronger and more durable than other base materials, glass ionomers and resin-modified glass ionomers.* Additionally, it is radiopaque allowing for easy identification on radiographs, providing a quick and effective diagnosis.

Unique Benefits:

  • Continuous release of calcium and fluoride ions1
  • Self-adhesive, no bonding agents required
  • High compressive strength, absorbs shock and stress from occlusal forces without fracturing
  • Radiopaque, allows for identification on radiographs and effective diagnosis
  • Auto-mix, dual syringe provides a consistent mix for immediate delivery with zero to minimal waste of material
  • Dual-cured material that will cure even in deep restorations where light cannot reach

Clinical Benefits:

  • Generates an alkaline pH (pH=11*) in minutes, which promotes pulp vitality2
  • Contains the adhesion promoting monomer MDP, ensuring reliable and optimal bond to dentin3

TheraBase and TheraCal LC – is there a reason to have both?
Yes. TheraBase is not intended to replace TheraCal LC. TheraBase is a material to be used as a base/liner under restorations while TheraCal LC is indicated for direct and indirect pulp capping and as a liner. They may both be used together in a sandwich technique case for optimum calcium and fluoride release benefits.

How are TheraBase and TheraCal LC different and/or alike?
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. TheraBase and TheraCal LC both utilize THERA technology, a hydrophilic resin matrix that facilitates calcium release. TheraBase and TheraCal LC are both radiopaque and generate an alkaline pH.

How thick can TheraBase be placed?
Bases are typically a thicker placement of material. TheraBase is dual-cured ensuring that your restorations will polymerize even in deep restorations where light cannot reach.

Do I need to bond before placing TheraBase?
Bonding is not required before the placement of TheraBase. TheraBase is a self-adhesive material and the benefits of the calcium and fluoride release are hindered if a bonding agent is placed between TheraBase and the dentin.

How many base applications can you get out of the 8g syringe of TheraBase?
Approximately 27-29 base applications.

What is the storage for TheraBase?
Store TheraBase at room temperature (68°-77° F; 20°-25° C).

How does TheraBase stand out compared to RMGI’s/GI’s base/liner materials?
TheraBase continuously releases both fluoride and calcium*, but GI’s and RMGI’s release only fluoride. TheraBase is offered in an auto-mix dual syringe providing consistent mix and immediate delivery. GI’s and RMGI’s, typically require manual mixing, trituration, or a special dispenser. TheraBase has higher flexural & compressive strength than most GI’s and RMGI’s, making it more durable and less prone to fractures.

What is the working time and setting time of TheraBase?
Working Time: Minimum 1 minute (includes mixing) at 22°C (71.6°F).
Setting Time: Maximum 5 minutes at 37°C (98.6°F).

What is the color of TheraBase?
