Understanding Dentin Bonding Understanding Dentin Bonding � Rationale for Wet Bonding Rationale for Wet Bonding • Dentin contains 15% water • Hydrophilic adhesive monomers are combined with Hydrophilic adhesive monomers are combined with solvents that chase moisture and carry the adhesive resin solvents that chase moisture and carry the adhesive resin into the open collagen and dentinal tubules. into the open collagen and dentinal tubules. • This forms a hybrid layer of collagen and resin with resin This forms a hybrid layer of collagen and resin with resin tags in the dentinal tubules that provides exceptional micro tags in the dentinal tubules that provides exceptional micro­ mechanical retention.

Understanding Dentin Bonding Understanding Dentin Bonding � Basic Anatomy Dentin is a fiber reinforced tissue consisting of minerals, collagen and water. The mineral content is mostly calcium phosphate. Cutting dentin with a rotary bur produces a smear layer of dentinal debris. Smear Layer Smear Layer Dentin Dentin Dentinal Tubules Dentinal Tubules Tubules

Understanding Dentin Bonding Understanding Dentin Bonding � Etching Etching dentin removes the smear Etching dentin removes the smear layer, dissolves the minerals at the layer, dissolves the minerals at the surface exposing the collagen fiber surface exposing the collagen fiber matrix, and slightly opens the dentinal tubules.

DenTASTIC UNO � Two Case Studies

DenTASTIC UNO: Case #1 DenTASTIC UNO: Case #1 Figure 1 Figure 2 Etch all enamel and dentin Rinse thoroughly and remove surfaces for 15 seconds. excess moisture leaving tooth surface slightly moist.

DenTASTIC UNO: Case #1 DenTASTIC UNO: Case #1 Figure 3 Figure 4 Apply 2­3 coats of UNO to Light cure for 10 seconds. all wet enamel and dentin Now you are ready to place surfaces. your preferred composite.

DenTASTIC UNO: Case #2 DenTASTIC UNO: Case #2 Figure 1 Figure 2 Acid etch all enamel and dentin Pulpdent Lime­Lite is placed over surfaces for 15 seconds. near exposure sites and light cured for 20 seconds.
