4.2 The Dental-Sealant-Application Process

Step 5: Dental Sealant Application

  • Follow the manufacturer’s instructions for mixing the sealant material and applying the dental sealant to the tooth surface.
  • Carefully flow sealant from one end of the fissure to the other to avoid air bubbles. If an air bubble does form, tease it out with an explorer tip or applicator tool before curing.
  • Do not overfill or underfill, and do not cover the marginal ridges with sealant material.

Step 6: Curing

  • For auto-polymerized sealants, allow sufficient time for dental sealants to cure, following manufacturer’s instructions. The temperature of the unused sealant material in the plastic well in which the components were mixed will indicate sealant polymerization. The sealant will become warm during the polymerization reaction. Once the heat subsides, the assistant should be able to remove the hardened sealant from the well. The sealant on the tooth should be set by then, as well.
  • For light-cured sealants, hold the light tip as close as possible to the surface without touching the sealant material.
  • Follow manufacturer instructions for curing time (consider manufacturer recommendations to be the minimum amount of time acceptable for curing).
  • If you are using a light-cured sealant, you must ensure that proper wavelength and intensity for each type of curing light (according to manufacturer instructions) are maintained by checking the light at least monthly for output and intensity with a meter designed for that purpose. Lights may be checked by a dental products supplier and repaired, if needed. Light meters are available for purchase through dental supply companies.
