Dental Caries (Cavities): School-Based Dental Sealant Delivery Programs

CDC

An Evidence-Based Practice

Description

Dental sealants are clear or opaque plastic materials applied to the chewing surfaces of the back teeth to prevent dental caries.

School-based programs provide dental sealants to students in two settings:
-Onsite at schools using portable dental equipment
-Offsite in dental clinics

Programs may target the following:
-Entire schools in low income neighborhoods
-Individuals within a school, based on their risk for tooth decay

Impact

The Community Preventive Services Task Force (CPSTF) recommends school-based programs to deliver dental sealants and prevent dental caries (tooth decay) among children.

Results / Accomplishments

Programs that delivered sealants within school settings increased the proportion of students who received sealants and decreased occurrence of tooth decay.

-Implementing a sealant delivery program led to a 26 percentage point increase in the number of students who received sealants (2 studies). Greater increases were seen among students from low-income families.
-Students who received dental sealants had a median of 50% fewer cavities up to four years later as compared with students who did not receive sealants (interquartile interval [IQI]: 38% to 61%; 2 studies).

In the systematic review of sealant efficacy, dental sealants were shown to reduce dental caries by a median of 81% at 2 year follow up (IQI:74% to 88%; 12 studies).
