- To unlock, pinch the sides of the cap and flip the cap back to expose the dispensing tip.
- Squeeze out the required drops into the disposable mixing well.
- Flip the cap back once finished, to secure by its locking mechanism.
Steps for Direct Light Cure restorations in Enamel and Dentin:
- Cavity Preparation
- Etching: After applying an etchant to enamel and dentine, wait for
some time and rinse. Blot excess water so that the surface should be
moist without pooling of water.
- Adhesive: Apply 2-3 consecutive coats of adhesive to etched enamel
and dentin for 15 seconds gently using a fully saturated applicator,
immediately after blotting
- Restorative placement, cure and finishing
Dental bonding adhesives normally rely on a micromechanical bond for
enamel and dentin adhesion. Prior to adhesion, total etch adhesives
rapidly demineralize the mineral phase of enamel and dentin by an acidic
agent. A gelled phosphoric acid with approximately 35% concentration is
generally used on the enamel which increases the surface area available
for bonding. This process is termed as acid etching. The porosities
formed by etching made it possible for low viscosity, polymerizable
resins to penetrate, thereby forming an interlocking mechanical bonding.
Studies shows that the incorporation of nano filled particles in
adhesives has marginally increased its detin bond strength (0.04MPa)
Few second etch of prepared dentin entirely dissolves the smear layer
and removes the mineral phase. A collagen phase which is resistant to
acid dissolution is present at the surface after washing off the
etchant. Penetration into this collagenous phase and its successive
polymerization offers an interlocking layer known as hybrid layer. The
dentin bond strength of Adper Single Bond when compared to other
Adhesives is much higher.
