Avoid contamination of the shade guide.
To prevent the shade guide from exposure to spatter or spray of body fluids or con-
taminated hands it is mandatory that the shade guide is handled offside the dental
unit with clean/disinfected gloves. For shade selection, remove individual tabs from
shade guide holder.
3.2 Cavity preparation
1. Clean the tooth surface with a fluoride free prophylaxis paste (e.g. Nupro
®
prophylaxis paste).
2. Prepare cavity (unless not necessary, e.g. cervical lesion).
3. Use adequate isolation such as rubber dam.
4. Rinse surface with water spray and carefully remove rinsing water. Do not desiccate the tooth
structure.
3.2.1 Matrix placement and wedging (Class II restorations)
1. Place a matrix (e.g. AutoMatrix
®
matrix system or Palodent
®
matrix system) and wedge. Burnish-
ing of the matrix band will improve contact and contour. Pre-wedging or BiTine
®
ring placement
is recommended.
