Dentamed ® P&B ® III based on alcohol is a light curing priming and bonding system that is easy to use and which does not require mixing prior to application. It was developed for a strong binding of composites and amalgam to tooth enamel and dentin as well as composites of non-precious and precious metals.

It’s strong adhesion to tooth enamel or dentin occurs in a similar manner as with glass ionomer cements. A good, durable adhesive strength and good biocompatibility are achieved with the methacrylic carbon acid ester. Dentamed ® P&B ®  therefore differs significantly from other adhesive systems, with which the adhesion is achieved with phosphate groups, which are however sensitive to hydrolysis and the adhesive strength can therefore become weaker over time. 

Dentamed ® P&B ®  is compatible with all light curing composite materials which are currently available on the market.

Constituents

Mixture of mono and difunctional methacrylates, polyacrylic acids, acetone, photo initiators, accelerators and stabilizers.

Side effects

Avoid contact with the skin, the mucous membranes and the eyes since allergies cannot be ruled out.

Contraindications

Avoid direct contact with the pulpa. Dentamed ® P&B ® is not to be used in persons who are known to react allergic to methacrylate.

Interactions

Materials containing eugenol are not to be used in connection with Dentamed ® P&B ® since thess could influence the curing of the material.

Therapeutic indications

Adhesive of light curing composites and amalgam on tooth enamel and dentin as well as compositions of non-precious and precious metals.

Use

To assure isolation against moisture, the use of a cofferdam is recommended.

1. Preparation of the cavity - Prior to the preparation, the tooth is to be cleansed of residues, concrements etc. The caivty is to be prepared so that as little possible of the healthy tooth material is lost. The cavity margin is to be a little chamfered (0.5 - 1-0 mm) on the tooth enamel so that the adhesive surface of the tooth enamel and thereby the adhsive strength can be increased.

2. Protection of the pulpa - In deep drillings, the cavity floor close to the pulpa must be covered with a thin layer of curing calciumhydroxide underfilling material.

3. Enamel and dentin conditioning - The total etching technique is recommended: ETCHING GEL (REF 5138) is applied to the enamel and dentin surfaces, starting with the enamel margins and allowed to work for 20 seconds. In deciduous teeth or highly flouridated teeth, an etching time of 60 seconds is recommended. Afterwards rinse with water for 20 seconds and dry with water and oil free
air. The dentin should not be overdried, since a slightly damp dentin surface is important for the function of Dentamed® P&B®. The etched enamel margin must have a chalk white appearance.

Precautionary measures during etching: It is important that tooth enamel already etched is not contaminated. Should a contamination occur, the etching must be repeated as described above. Avoid contact of the etching gel with the skin, mucous membranes and eyes. Should accidental contact occur, rinse thoroughly with water.

4. Application of Dentamed® P&B® - A sufficient amount of Dentamed® P&B® is applied to the dentin and enamel surfaces with a brush and the primer is intensively brushed in for 30 seconds. Note is to be taken that the dentin surfaces to be impregnated are kept damp with the primer over the entire prescribed time.
Attention is to be taken that the material is distributed homogenous and over the entire surface. Remove possible excess material. All volatile components are removed afterwards through soft blowing with pressurized air (approx. 15 seconds) and the adhesive
thereby distributed to an even layer. Do not overdry the dentin.
Note: Do not spill Dentamed® P&B®! Close the bottle immediately after the removal of Dentamed® P&B®.
Note: If it is not use immediately, Dentamed® P&B® which has already been removed from the bottle is to be stored under low lighting in order to avoid premature polymerization from light.

5. Curing of Dentamed® P&B® - The Dentamed® P&B® coating is cured with 20 seconds of constant radiation with a suitable dental lamp.
Note Dentamed® P&B®does not cure by itself. It is important that the primed dentin surface and the etched enamel are kept dry and clean before the next application is performed.
6. Application of a second layer of Dentamed® P&B® - The application of a second layer of Dentamed® P&B® is recommended. This is done in the same manner as the first application as described above. After curing of this second layer with a dental lamp, a light curing composite can be applied.
7. Laying the filling, curing and finishing - Please refer to the instructions for the light curing filling material used.
Warning: Dentamed® P&B® contains acetone. Acetone is highly flammable. Keep away from sources of ignition. Do not smoke. Do not inhale fumes. Take measures against electrostatic charging. Keep out of reach of children. Only to be used by the dentist.
