Sealants: The Added Link in Prevention

Course Number: 673

Step Eight - Evaluate the Sealant

Immediately after the material has cured the sealant should be evaluated for retention, flaws, and occlusion. Use an explorer to check for retention and flaws. If a sealant is going to fail, it most likely will do so immediately. If there are bubbles, voids, or any portion of the material comes out, more sealant material may be added. It will be necessary to re-isolate and etch before placing the material again. The occlusion of the sealant should be checked with articulating paper (Figures 18‑19). If there is any indication of interference, the excess sealant material should be removed using a round finishing bur in a high or slow speed handpiece.

Some additional recommendations:

  • Treat one quadrant at a time

  • Use of an assistant and four-handed dentistry can expedite the process and help ensure proper technique, particularly when isolation is critical.

  • Patient and clinician should wear safety goggles.
