  • Radiopaque
  • Higher compressive strength
  • Lower solubility
  • Quick set time and excellent handling characteristics

Dycal is a rigid, self-setting material useful in pulp-capping(direct and indirect pulp capping), and as a protective base/liner under dental filling materials. It will not inhibit the polymerization of acrylic and composite restorations. 

Based on the original Dycal formulation, Dycal Radiopaque Calcium Hydroxide Composition provides potential for improved esthetics, as well as clinically proven performance. Dycal offers improved physical properties with higher compressive strength and lower solubility than the original Dycal product that serves as the standard in calcium hydroxide materials. The quick set time and excellent handling characteristics of Dycal have helped make it the #1 selling calcium hydroxide composition.

Dycal stimulates the formation of secondary dentin.

  • 1 x Tube Base Paste- 13g
  • 1 x Tube Catalyst Paste-11g
  • 1 x Mix Pad


  1. Direct Pulp Capping
    1. rubber dam isolation, complete cavity preparation outline using high-speed burs under constant water-cooling.
    1. caries is present, completely excavate using low-speed and/or hand instrumentation.
    2. the cavity and exposure site(s) with 2.6%-5% NaOCl. Heavy bleeding may be controlled with a cotton pellet moistened with sterile saline.
    3. dry preparation with cotton pellet. Avoid desiccation.
    4. 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. Complete mixing within 10 seconds. NOTE: Do not attempt to control the setting time by increasing or decreasing the amount of catalyst dispensed.


    1. the ball-pointed Dycal® Liner applicator or similar instrument, place the mix directly on the exposed pulp and cavity dentin judged to be less than 1.0mm remaining thickness in a thin layer. Avoid placing Dycal®

Liner on enamel or the margins of the cavity. Avoid placing a large bulk of material. Material thickness should be approximately 0.8mm-1mm.

    1. 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.
    2. any set excess from retention areas, enamel, and/or margins with a sharp spoon excavator or a bur.
    3. desired adhesive, base, and/or restoration following manufacturer’s directions.
    1. the next appointment, assess the pulp vitality. Pulp vitality and status should be assessed radiographically every three to six months or as needed.
  1. Indirect Pulp Capping, Protective Barrier
    1. suitable isolation, complete cavity preparation and caries removal. Wash cavity thoroughly with water spray and air dry.
    1. and mix Dycal® Liner components as outlined above in section 1.5.
    2. mixed material to desired dentin surfaces as outlined above in sections 1.6-1.8. Quick application of the mixed material into the cavity takes advantage of the essential flowability of the mass for efficient placement before setting starts. Completely covering all cavity dentin as desired may require carrying additional material from pad to dentin surfaces. NOTE: If subsequent use of a dentin bonding agent is desired, place Dycal® Liner only on the deepest (less than 1mm remaining) dentin, leaving the rest of the cavity surface free for bonding.
    3. completion of set (see section 1.7) remove any set excess from retention areas, enamel, and/or margins with a sharp spoon excavator or a bur.
    4. restoration per restorative material manufacturer’s directions for use.



Tubes and caps may be cleaned by scrubbing with hot water and soap or detergent. Tubes should be wiped, not immersed. Tubes exposed to spatter or spray of body fluids, or touched by contaminated hands or oral tissues, should be disinfected with a hospital-level disinfectant. Acceptable disinfectants are EPA registered as tuberculocidal. Iodophors, sodium hypochlorite (5.25%), chlorine dioxide and dual or synergized quaternaries are approved disinfectants. Do not immerse tubes in disinfectant. Disinfect the tubes by spraying or wiping with any recommended hospital-level surface disinfectant for the contact time recommended by the disinfectant manufacturer for optimum results. Spraying with glutaraldehyde is not recommended. Some phenolic-based agents and iodophor-based products may cause surface staining. Agents containing organic solvents such as alcohol may tend to degrade the tubes and caps. The disinfectant manufacturer’s directions should be followed properly for optimum results. Water-based disinfectant solutions are preferred.
