Dentin Bonding with DenTASTIC UNO
|
A.
Basic Anatomy
Dentin is a fiber reinforced tissue consisting of minerals, collagen and water.
The mineral component is mostly calcium phosphate in the form of hydroxyapatite.
Cutting dentin with a rotary bur produces a smear layer of dentinal debris.

B.
Surface Treatment
Etching dentin removes the smear layer, dissolves the minerals at the surface exposing the collagen fiber matrix,
and slightly opens the dentinal tubules.
All the popular dentin etchants (maleic, nitric and phosphoric acid) achieve the same results.

C.
DenTASTIC UNO
Combines the primer and unfilled resin phases into a single
component adhesive. It forms an interlocking matrix with
the exposed collagen and dentinal tubules, creating a
"hybird layer" which provides extraordinary
micromechanical retention. UNO forms an unfilled resin
layer to which composite and resin cement will chemically
bond with great strength.
