Oklahoma Pit and Fissure Sealants State Practice Exam

What is an ideal condition for applying dental sealants?

1. Upon emergence of permanent molars

2. Only when there is visible decay

3. When teeth are not adjacent to each other

4. Before the age of 18

The correct answer is: Upon emergence of permanent molars

Applying dental sealants is ideally done upon the emergence of permanent molars. This timing is critical because the first molars typically erupt around ages six to seven, when the risk of decay in these newly erupted teeth begins to increase. The placement of sealants at this stage helps to provide a protective barrier against bacteria and food particles, reducing the likelihood of cavities developing in the pits and fissures that are common in molars. Newly emerged permanent molars are more susceptible to decay due to their complex surfaces, which can harbor plaque. By sealing these surfaces early, practitioners can significantly lower the chances of decay during the years when children are most vulnerable to caries. This preventive measure is most effective while the teeth are still in the early stages of eruption and before harmful bacteria have had the opportunity to establish a foothold. The other choices are not ideal conditions for sealant application. Waiting until there is visible decay may allow the decay to progress further, potentially necessitating more invasive treatments later. Applying sealants on teeth that are not adjacent to each other does not inhibit their effectiveness, but the focus should primarily be on sealing molars as they emerge. Lastly, while sealants can be beneficial for patients up to age 18 and beyond, their primary
