Dental Sealant Material Safety

Allergic Reactions

A small proportion of the population is known to be allergic to acrylate resins, such as those used in some dental sealant materials. Program staff should not use any resin-based sealant materials with children who have known acrylate allergies.

Injury Prevention

Staff and child shown with face protectionFollowing are guidelines for preventing injury:

  • Wear safety glasses (e.g., chin-length face shields, eyewear with side shields) during the sealant-application process (recommended for staff and children), and have an eye wash fountain/bottle available.
  • Do not allow etchant (phosphoric acid) or uncured sealant material to come into contact with the eyes, skin, or oral soft tissues. Transitory contact with soft tissues, such as those adjacent to a buccal or lingual groove, during sealant application is not dangerous.
  • If uncured sealant material inadvertently comes into contact with the skin, rinse immediately with soap and water. If contact with the eyes or prolonged contact with oral soft tissues occurs, flush with large amounts of water. If irritation persists, seek medical attention.
  • If uncured sealant material contacts a glove, remove it, wash hands with soap and water immediately, and re-glove.
  • If etchant contacts the skin or soft tissues, rinse immediately with water. If contact with the eyes occurs, immediately initiate the emergency eyewash procedure, as follows:
    • The injured person should flush his or her eye(s) with eyewash solution or water.
    • When the first bottle of eyewash is emptied, the injured person should begin flushing with the second bottle.
    • As each bottle is emptied, another member of the team should refill the bottle so the wash may be continued for 15 minutes.
    • After the 15 minutes has passed, the injured person should seek medical attention.
    • After an emergency eyewash procedure, supplies must be replenished.
