as NUPRO ® Prophylaxis Paste. Wash thoroughly with water spray and blot or lightly air dry.
Do not desiccate dentin.
• Indirect restoration
• Treat surface of restoration according to manufacturers or dental laboratory's
instructions, i.e., etching or mechanical roughening.
• Apply Calibra ® Silane Coupling Agent (available separately) to ceramic restorations
designed to be silanated following manufacturer's instructions.
• A. Light cured cement e.g., veneer cementation
• Apply a single coat of Prime&Bond Elect
surface of the restoration. Immediately air dry for 5 seconds.
• B. Dual/Self cured cement e.g., full coverage crown
• Apply a single coat of Prime&Bond Elect
mixture to the internal bonding surface of the restoration. Immediately air dry for
5 seconds.
• Cure mixed adhesive/activator for 10 seconds.
• Composite, ceramic and amalgam repairs (light cured composite resin and compomers)
• Preparation, Cleaning: Roughen the fractured surface as much as possible with a
diamond bur. Create mechanical retention where possible. For best results, sandblast
the area to be repaired with an intraoral microetcher (50µ alumina). Rubber dam is
recommended with high speed evacuation. Rinse microetched areas for 15-20
seconds with water. Air dry. NOTE: Bevel porcelain margins before etching.
• Etch ceramic restoration repair area with hydrofluoric acid according to
manufacturer's instructions.
• Treatment of the Restoration: Rinse with water for 10 seconds. Air dry. NOTE: Apply
Calibra ® Silane Coupling Agent to porcelain surfaces to be repaired following
manufacturer's instructions.
2. Pulp protection
For direct and indirect pulp capping, cover the dentin close to the pulp (less than 1mm) with
a hard setting calcium hydroxide liner (Dycal
for bonding with Prime&Bond Elect
3. Enamel and dentin pre-treatment
Prime&Bond Elect ® Adhesive offers operators the choice of enamel and dentin pre-treatment
prior to adhesive application:
Total-Etch (34% phosphoric acid application to enamel and dentin), Selective-Etch (34%
phosphoric acid application to enamel only), or Self-Etch (no pre-treatment with phosphoric
acid).

3.1 Total-Etch option
• After application of rubber dam or other suitable isolation technique, apply Caulk
34% Tooth Conditioner Gel. Attach disposable needle to end of syringe, needle tip
may be bent for easy access. Gently extrude conditioner gel to the cavity surfaces
starting at the enamel margins. For best results, condition enamel for at least 15
seconds and dentin for 15 seconds or less.
• Rinsing and Drying: Remove gel with aspirator tube and/or vigorous water spray and
rinse conditioned areas thoroughly for at least 15 seconds. Remove rinsing water
completely by blowing gently with an air syringe or by blot drying with a cotton pellet.
Do not desiccate dentin. Proceed immediately to application of Prime&Bond Elect
Adhesive.
• Once the surfaces have been properly treated, they must be kept uncontaminated. If
salivary contamination occurs, thoroughly clean with vigorous water spray, dry, and
repeat conditioning procedure of enamel for 5 seconds only. Rinse and dry as
described above.
3.2 Selective-Etch option
• Apply Caulk ® 34% Tooth Conditioner Gel as above, gently extruding to the enamel
(margins) only. For best results, condition enamel for 15 seconds. Any incidental
contact of conditioner gel to dentin should be limited to 15 seconds or less.
• Rinse and dry as outlined above.
3.3 Self-Etch option
• No application of Caulk ® 34% Tooth Conditioner Gel. Following cleaning Section 1 of
3.1 General procedures and pulp protection Section 2 of 3.1 General procedures,
proceed directly to adhesive application below.
3.2 Prime&Bond Elect ® Universal Dental Adhesive Application
Light Cured Procedures: Prime&Bond Elect

• Unit Dose Container: Grasp container at each end, placing thumb along center score.
Firmly apply pressure until container separates. Discard separated cap. Unit Dose
container may be placed on the tabletop or held between fingers for convenience.
Insert disposable applicator into opening to saturate applicator tip.
• Conventional Bottle: Place 2-3 drops of Prime&Bond Elect
well. Replace cap promptly.
• Using the disposable microbrush applicator tip supplied, immediately apply generous
amounts of Prime&Bond Elect
the applied adhesive for 20 seconds. Re-wetting of the microbrush may be required in
order to coat the preparation for the full 20seconds.
• Remove excess solvent by gently drying with clean, dry air from a dental syringe for at
least 5 seconds. Recommended technique is to begin drying/evaporation with the syringe
approximately 4-6 inches (10-15cm) away from the surface, gradually bringing the source
to within 0.5 inches (10mm) of the surface. Surface should have a uniform glossy
appearance. If not, repeat application and air dry. Surface should not show areas of
excessive adhesive thickness or pooling. Repeat air drying/evaporation outlined above if
necessary.
Inadequate polymerization due to insufficient solvent evaporation
• Follow evaporation instructions above
• Cure Prime&Bond Elect
containing 470nm, minimum light output at least 550mW/cm
completion/restorative material placement.
Inadequate polymerization due to insufficient curing
• Check compatibility of curing light
• Check curing cycle
• Check curing output before each procedure
• Completion: Place light cured restorative material, light cured resin cement or fresh
amalgam over the cured Prime&Bond Elect
manufacturer's directions. NOTE: When used as a cavity varnish, Prime&Bond Elect
Adhesive is not an amalgam adhesive.
3.3 Prime&Bond Elect ® Dual Cured Adhesive Application
Dual Cured or Self Cured Procedures: Prime&Bond Elect
mixture
• Direct, dual cure or self cure composite restorations and core build-ups.
• Indirect restorations; dual cured and self cured resin cemented inlays, onlays, crown and
bridge retainers.
• Dual cured and self cured resin cemented endodontic post cementation.
• Adhesive bonding of direct amalgam restoration.
• Clean preparation and treat restoration following Section 1 of 3.1 General procedures.
Place Dycal ® Liner if needed following Section 2 of 3.1 General Procedures.
• For direct core build-up, place pin, post or matrix as needed.
• Tooth Conditioning/Dentin pretreatment: See Table 3 for clinical recommendations. Follow
Section 3.1 Total-Etch option,
3.2 Selective-Etch option, or 3.3 Self-Etch option for selected technique.
• Application of Prime&Bond Elect
and dentin pre-treatment option
• Place 1-2 drops of Prime&Bond Elect
Replace cap promptly.
• Place an equal number of drops of Self Cure Activator into the same mixing well.
Replace cap promptly. Mix contents for 1-2 seconds with a clean, unused brush tip.
® • Using the disposable microbrush applicator tip supplied, immediately apply generous
amounts of mixed Adhesive/Activator to thoroughly wet all the tooth surfaces. Agitate
the applied adhesive/activator mixture for 20 seconds. NOTE: For endodontic post
cementation, a paper point pre-wet with the adhesive mixture may aid in bringing the
adhesive mixture down to the deepest portion of the preparation.
• Remove excess solvent by gently drying with clean, dry air from a dental syringe for
at least 5 seconds. Recommended technique is to begin drying/evaporation with the
syringe approximately 4-6 inches (10-15cm) away from the surface, gradually bringing
® the source to within 0.5 inches (10mm) of the surface. Surface should have a uniform
glossy appearance. If not, repeat application and air dry. Surface should not show
areas of excessive adhesive thickness or pooling. Repeat air drying/evaporation
outlined above if necessary. NOTE: For endodontic post cementation, use of clean,
dry paper points may aid in thorough removal of solvent/excess adhesive in post
space.
