Oklahoma Pit and Fissure Sealants State Practice Exam

The effectiveness of dental sealants is primarily observed in which locations of teeth?

1. Front surfaces

2. Occusal surfaces

3. Interproximal surfaces

4. Gingival surfaces

The correct answer is: Occusal surfaces

The effectiveness of dental sealants is primarily observed on the occlusal surfaces of teeth. Occlusal surfaces are the top surfaces of the molars and premolars where chewing occurs. These surfaces contain pits and fissures that are highly susceptible to cavities because they can be difficult to clean thoroughly with regular brushing. Sealants are designed to fill these pits and fissures, creating a smooth surface that is easier to clean and helps prevent the accumulation of plaque and bacteria, which lead to decay. The application of sealants in these areas has been shown to significantly reduce the incidence of dental caries in children and adolescents, making it a critical preventive measure in pediatric dentistry. In contrast, the other surface types listed, such as front, interproximal, or gingival surfaces, do not benefit from sealants in the same way, since these areas are less prone to decay due to their smoother surfaces and different cleaning dynamics. As a result, sealants are specifically indicated for occlusal surfaces to enhance dental health effectively.
