Oklahoma Pit and Fissure Sealants State Practice Exam

During which age range are sealants particularly effective for preventing caries?

1. 0-5 years

2. 6-15 years

3. 16-20 years

4. 21-30 years

The correct answer is: 6-15 years

Sealants are particularly effective for preventing caries in individuals aged 6 to 15 years. During this age range, children and adolescents are at an increased risk for dental caries due to several factors: the eruption of permanent teeth, dietary habits that often include high sugar intake, and the developmental stages of oral hygiene practices. The molars, which are prominent targets for sealant application, typically emerge in this age group. By sealing the grooves and pits of these teeth, the risk of decay is significantly reduced because the sealants act as a physical barrier against food particles and bacteria that contribute to cavities. Furthermore, in younger individuals, the likelihood of partially brushing or flossing these difficult-to-reach areas makes sealants an invaluable preventative measure. While sealants can still provide benefits outside of this age range, their primary effectiveness is concentrated during the development of permanent dentition when the risk of caries is high. This understanding underlines the critical window for intervention, making it clear why this specific age range is emphasized for sealant application.
