- Tooth should present
as smooth a surface as possible. Smooth dentin surfaces are more easily
cleaned of debris that can inhibit chemical bonding.
- Avoid contaminating
surface of dentin with wax, oil, varnish or any protein material that
can inhibit chemical bonding.
- Clean tooth surfaces.
Tooth surface should not be dehydrated when cement is applied. Excessive
drying concentrates protein debris and prevents efficient wetting of
tooth surface.
- Never use varnishes
to protect tooth if polyacrylic acid cements are used (prevents bonding
to tooth structure).
- Margins of cement
should be protected with varnish after initial set (5 to 6 minutes).
Under no circumstance should saliva come into direct contact with unset
cement.
