3.3 Pulp protection, tooth conditioning/dentin pre-treatment, adhesive application
Refer to adhesive manufacturer’s Instructions for Use for pulp protection, tooth conditioning and/or
adhesive application. The Dentsply Sirona Xeno
®
adhesives are applied in the self etch technique.
Prime&Bond
®
XP is applied in the etch and rinse technique. Prime&Bond
®
NT in combination with the
Dyract
®
restoratives may be applied in both techniques. Once the surfaces have been properly
treated, they must be kept uncontaminated. Proceed immediately to placement of the material.
3.4 Application
Apply material in increments immediately after the application of the adhesive. The material is de-
signed to be cured in increments up to a 2 mm depth/thickness.
Using Compules
®
Tips
1. Insert Compules
®
Tip into the notched opening of the Compules
®
Tips Gun. Be certain that the
collar on the Compules
®
Tip is inserted first.
2. Remove the colored cap from the Compules
®
Tip. The Compules
®
Tip may be rotated 360° to
gain the proper angle of entrance into the cavity or to the mixing pad.
DO NOT USE EXCESSIVE FORCE.
Indirect use: to prevent Compules
®
Tip from exposure to spatter or spray of body fluids or con-
taminated hands it is mandatory that the Compules
®
Tip is handled offside the dental unit with
clean/disinfected gloves. Dispense the necessary amount of material onto a mixing pad and
protect against light. Apply material into the cavity with a plastic instrument.
- or -
Dispense the material directly into the cavity preparation using a slow, steady pressure.
3. To remove the used Compules
®
Tip, be sure that the Compules
®
Tips Gun plunger is pulled back
completely by allowing the handle to open to its widest position. Apply a downward motion to the
front end of the Compules
®
Tip and remove.
Excessive force.
Injury.
1. Apply slow and steady pressure on the Compules
®
Tips Gun.
2. Do not use excessive force. Compules
®
Tip rupture or ejection from Compules
®
Tips Gun may result.
3.5 Light curing
1. Light cure each area of the restoration surface with a suitable curing light
2
. Minimum light output
must be at least 500 mW/cm
2
. Refer to curing light manufacturer’s Instructions for Use for com-
patibility and curing recommendations.
2. Cure each layer according to the table below.
Insufficient curing.
Inadequate polymerization.
1. Check compatibility of curing light.
2. Check curing cycle.
3. Check minimum irradiance.
4. Cure each area of each increment for the recommended curing time.
2
Curing light designed to cure materials containing camphorquinone (CQ) initiator. Peak of spectrum in the range of
440-480 nm.
