IDS ( immediate dentin sealing) protocol


-prep tooth according to biomimetic principles

-etch exposed dentin for no longer than 15 seconds.

-gently dry leaving moist dentin

-apply primer  (optibond FL) with microbrush for 15 seconds, evaporate solvent. if needed, apply second coat.

-apply bonding agent (optibond FL) to exposed dentin. DO NOT BLOW THIN, I was doing so as I usually do with composite restorations, and when I use sandblaster during cementation, some of the bonding agent was removed and it caused post-op sensitivity

-light cure

-air block with glycerin

-light cure again.

--scrub sealed dentinal area with fine pumice on cotton pellet to remove remaining oxygen inhibiting layer. rinse off pumice

-remove bonding agent on enamel or margins by oscillating tips, or finishing burs. pack cords to protect gingiva prior to finishing if necessary.  Pack wax to block out undercut where the impression material can get locked and tear upon removal, it usually happens at gingival embrasures with margins away from gingiva

-impression.

it may look complicated, but it does not take much longer. the bonding strength is greatly increased in comparison to delayed bonding at cementation, there are actually a lot of benefits. The main one for me is: no post-op sensitivity!
