Oklahoma Pit and Fissure Sealants State Practice Exam

The fraction of caries that occur on occlusal surfaces is 2/3, which highlights the significance of these surfaces in susceptibility to decay. The occlusal surfaces of molars and premolars are particularly prone to caries due to their complex anatomy, featuring pits and fissures that can retain plaque and food debris more readily than smooth surfaces. This complexity provides ideal conditions for bacterial colonization and acid production, leading to enamel demineralization and the onset of caries.

Understanding that a significant amount of caries occurs on these surfaces emphasizes the importance of preventive measures, such as the application of pit and fissure sealants, which can act as a barrier to protect these vulnerable areas from decay. Monitoring and focusing on the health of occlusal surfaces is essential in dental practice, making this information invaluable for careers in preventive dentistry and oral health education.
