Sealant is a flowable composite based resin which is painted into the groves of molars, which have a greater potential to trap food and develop caries. Sealed teeth have fewer areas where food may become lodged and are easier for patients to keep clean.

 

 

Step1: What is a sealant?

  • A sealant is a flowable composite based resin which is painted into the grooves of molars, which have a greater potential to trap food and develop caries.
  • Sealed teeth have fewer areas where food may become lodged and are easier for patients to keep clean

Step 2: Preparation

  • Some teeth might require an initial debridgement of the grooves prior to placing a sealant
  • The deepest areas of the chewing surfaces of the teeth have the highest chance of meeting this criteria
  • This is accomplished with a small round bur which is used to mechanically remove any suspicious areas prior to sealant placement
  • In most situations this can be accomplished with no local anesthetic

Step 3: Isolation and Etchant

  • Sealants are water sensitive and require proper isolation from saliva and other oral contaminants for adhesion
  • After isolation, a 37% phosphoric acid etchant (blue color) is placed on the tooth to prepare the enamel for the sealant.
  • The etchant is painted on the tooth and left for 10-15 seconds prior to be washed off and the tooth dried completely with water and air.

Step 4: Bonding agent

  • After the tooth is completely dried, a clear bonding agent is painted on the surface which will receive the sealant
  • This bonding agent is then receiving a few "puffs" of air to ensure it is spread evenly, and light cured to leave a glossy appearance

Step 5: Placement of sealant

  • The sealant material is then placed onto the surface of the tooth
  • The material will flow into the grooves of the tooth as it is spread by the brush
  • This material is also light cured to leave a hard, shiny, protective coating

Step 6: Checking the sealant

  • The correct placement of a sealant can be checked by taking the fine tip of a dental explorer and moving across the surface of the sealant checking of softness, voids, and/or inconsistencies.
