Dental Protective Liner

Dental base/liners are useful tools for dental practitioners. The base/liner is composed of a calcium hydroxide paste, which encourages repair of active calcification and provides protection from external stimuli. The high pH of the paste also restricts the growth of microbes and harmful pathogens.

Our dental base/liner, PulpCAL, is easy to use and designed to deliver excellent results. It also comes with a paper parchment pad for mixing the contents before application.

    Radiopaque Calcium Hydroxide Composition

    Radiopaque Calcium Hydroxide Composition is a rigid, self-setting material useful in pulp-capping, and as a protective base/liner under dental filling materials. It will not inhibit the polymerization of acrylic and composite restorations. Calcium hydroxide paste encourages repair of active calcification and acts as a protection to external stimuli. Promotes re-calcification of minerals and high pH of paste has an antimicrobial effect against growth of harmful pathogens.


    Base Paste: 1, 3 butylene glycol disalicylate, calcium phosphate, barium sulphate, zinc oxide, iron oxide, calcium sulphate and titanium dioxide.

    Catalyst Paste: calcium hydroxide, ethyl toluenesulphonate, zinc stearate, titanium dioxide, and zinc oxide.


    1. Applicable to exposed vital pulp tissue.

    2. Application to dentine as protective barrier between restorative barrier between materials and deep vital dentine (indirect pulp capping) or where dentine to restorative material contact is not desired.

    3. Direct pulp capping.


    Avoid prolonged or repeated exposure of liner material with skin, oral soft tissue, and eyes. Irritation and possible corneal damage may result. Skin rash, oral mucosa, or other allergic reactions may result in susceptible individuals. Do not take internally.

    Direction of use:

    1. Direct Pulp capping: Dispense equal volumes of base and catalyst paste (1.17:1 by weight) on parchment paper pad provided. Replace container caps. Using a liner applicator, stir immediately to mix thoroughly until a homogenously uniform mixer is observed. Complete mixing within 10 seconds.

    Using a ball pointed calcium hydroxide liner applicator or similar instrument, place the mix directly on exposed dental pulp and cavity dentine judged to be less than 1.0mm remaining thickness in a thin layer. Avoid placing a liner on enamel or margins of cavity. Allow the liner to set completely. The mixed material will set in approximately 2-3 minutes on the mixing pad under normal room conditions. Set time is shorter in mouth due to moisture and temperature.

    2. In direct Pulp capping, Protective barrier; under suitable isolation, complete cavity preparation and caries removal. Wash the cavity thoroughly with water spray and air dry. Disperse and mix liner components as outlined above.

    Apply mixed material to desired dentine surfaces as outlined above.
