expiration date.
3. STEP-BY-STEP INSTRUCTIONS
Prime&Bond elect Adhesive offers the operator total flexibility to utilize:
• selective phosphoric acid etching of just enamel;
• phosphoric acid etching of both enamel and dentin;
• or no phosphoric acid etching prior to application
3.1 General procedures
Cleaning: Preparation for all adhesive procedures
Clean freshly instrumented enamel and dentin with water spray and then air dry. Clean
uninstrumented enamel and dentin with a rubber cup and pumice or a cleaning paste such 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. NOTE: Prime&Bond elect Adhesive contains phosphate
monomers and has an affinity for zirconium-based restorations following 50µ aluminum oxide
sandblasting.
• Apply Calibra
®
Silane Coupling Agent (available separately) to ceramic restorations designed
to be silanated following manufacturer's instructions.
• Once silanated, resin cement may be placed directly on the silanated surface. Adhesive
placement on the bonding surface of silanated restorations is not necessary.
• For zirconium, metal or other non-silanated restorations, follow adhesive application
instructions below:
A. Light cured cement e.g., veneer cementation
• Apply a single coat of Prime&Bond elect Adhesive to the internal bonding surface of
the restoration. Immediately air dry for 5 seconds.
B. Calibra Ceram Cement e.g., full coverage crown, endodontic post
• Apply a single coat of Prime&Bond elect Adhesive to the internal bonding surface of
the restoration. Immediately air dry for 5 seconds.
C. Dual/Self cured conventional resin cement (other than Calibra Ceram Cement) e.g., full
coverage crown, endodontic post
• Apply a single coat of Prime&Bond elect Adhesive mixed with Self Cure Activator 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.
3.2 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
bonding with Prime&Bond elect Adhesive.
3.3 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/etch & rinse (34% phosphoric acid application to enamel and dentin), Selective-
Etch/etch & rinse (34% phosphoric acid application to enamel only), or Self-Etch (no pre-
treatment with phosphoric acid).

Recommended Enamel & Dentin
Pre-treatment
• Total-Etch/etch&rinse – 34%
phosphoric acid application to enamel
and dentin
• Selective-Etch/etch&rinse – 34%
phosphoric acid application to enamel,
incidental dentin contact
• Self-Etch – No application of
phosphoric acid
NOTE: When using Calibra Cement for
endodontic post cementation, total-
etch/etch&rinse is recommended
3.3.1 Total-Etch/etch & rinse option
• After application of rubber dam or other suitable isolation technique, apply Caulk
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.
3.3.2 Selective-Etch/etch & rinse 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.
3.3.3 Self-Etch option
• No application of Caulk 34% Tooth Conditioner Gel. Following cleaning Section 3.1 General
procedures and Section 3.2 Pulp protection. General procedures, proceed directly to
adhesive application below.
3.4 Prime&Bond elect Adhesive Application
Light Cured Procedures: Prime&Bond elect Adhesive
• Direct, light cured composite and compomer restorative
• Indirect restorations; light cured, resin cemented veneers
• Indirect restorations; Calibra Ceram Cement (dual cure or self cure) cemented inlays, onlays,
crown and bridge retainers
• Composite, ceramic and amalgam repairs
• Cavity varnish for use with fresh amalgam
3.4.1 Application of Prime&Bond elect Adhesive following selected enamel and dentin pre-
treatment option
• 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 Adhesive into a clean well.
Replace cap promptly.
• Using the disposable microbrush applicator tip supplied, immediately apply generous
amounts of Prime&Bond elect Adhesive to thoroughly wet all the tooth surfaces. Agitate the
applied adhesive for 20 seconds. Re-wetting of the microbrush may be required in order to
coat the preparation for the full 20 seconds.
• 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
3.4.2 Cure Prime&Bond elect Adhesive
Cure* Prime&Bond elect Adhesive for 10 seconds using a curing light, spectral output
containing 470nm, minimum light output at least 550mW/cm
completion/restorative material placement.
*Technique Note: When Prime&Bond elect Adhesive is used with Calibra Ceram Cement
for light transmissible ( 2.5mm thick ceramic, composite) indirect restoration cementation,
adhesive curing may be completed with visible light curing of cement through the
restoration following insertion.
