HOTTEL BASES AND
LINERS
8. dimensional changes
9. lack of marginal seal
Basic function of a sealer? - ANSWERS-1. seal off dentin tubules/
prevent chemical irritation
2. reduces leakage around restoration
3. Do not offer thermal protection
Cavity varnish - ANSWERS-a thin layer placed on the floor and walls of
the preparation to seal the tubules and minimize micro-leakage on
amalgam fillings.
