What are dental sealants?

Reset Decrease Increase
Dental sealants are thin plastic coatings that are applied to the grooves on the chewing surfaces

Deep pits and fissures are the source of some 80 % of tooth cavities. This is mainly because food and bacterial plaque lodge in these tight crevasses that are often inaccessible to toothbrush bristles.

Plaque acids and enzymes at the base of these grooves cause the tooth enamel to dissolve, eventually leading to cavities.

Dental sealants and fissurotomy techniques may help protect against these types of cavities. This animation opens by describing the epidemic nature of pit & fissure cavities, and the impetus for their prevention.

Pits and fissures are shown in cross-section, and dissolution of tooth enamel in the inaccessible fissures is illustrated- ultimately progressing to caries in dentin.

Prophylactic odontotomy (fissurotomy) is described as a potentially viable means of eliminating deep fissures, along with use of microabrasion handpieces to debride the grooves.

Sealants are applied, stressing the importance of good moisture control. Microleakage is discussed as a possible consequence of maintaining poor moisture control during placement, followed by caries progression which may be difficult to observe clinically.

Finally, a failing sealant is shown, which illustrates the most common problems associated with sealants.
