Oklahoma Pit and Fissure Sealants State Practice Exam

For newly erupted teeth, the highest risk for decay is within which time frame?

1. 1-2 years

2. 2-3 years

3. 3-4 years

4. 4-5 years

The correct answer is: 3-4 years

The correct answer indicates that the highest risk for decay in newly erupted teeth occurs within the 3-4 year time frame following their eruption. This period is particularly critical because newly erupted teeth, such as molars, have not yet fully mineralized and may still have relatively shallow pits and fissures that are more susceptible to bacterial colonization and plaque accumulation. During this phase, the enamel is also undergoing a maturation process which makes it more vulnerable to acid attack from the bacteria responsible for caries. Additionally, children may not have fully developed their oral hygiene practices, leading to an increased risk of decay as they may not effectively clean these hard-to-reach areas. Hence, the 3-4 year time frame serves as a crucial window for the implementation of preventive measures such as topical fluoride application and dental sealants to protect these vulnerable newly erupted teeth from dental caries.
