What is the purpose of a dental sealant?

1. To make teeth stronger

2. To prevent occlusal caries

3. To improve chewing function

4. To enhance tooth color

The correct answer is: To prevent occlusal caries

The purpose of a dental sealant is primarily to prevent occlusal caries, which are cavities that form on the chewing surfaces of the teeth, particularly the back molars. Sealants are thin plastic coatings that are applied to these surfaces to create a protective barrier against food particles and bacteria that can lead to decay. By filling in the grooves and pits on the occlusal surfaces, sealants help to keep these areas cleaner and reduce the risk of cavities forming, particularly in children and adolescents who are more prone to dental caries. This preventive measure is an important part of maintaining oral health and minimizing the long-term effects of tooth decay.
