1. 3 times

2. 5 times

3. 8 times

4. 10 times

The correct answer is: 8 times

The development of dental caries, or decay, is influenced by various factors, including the type of tooth surface. Research indicates that posterior occlusal surfaces are significantly more prone to caries than smooth surfaces due to their complex anatomy, which includes pits and fissures. These features create niches where plaque and bacteria can accumulate, making it difficult to clean thoroughly with regular brushing. Studies have shown that posterior occlusal surfaces are approximately eight times more likely to develop decay compared to smooth surfaces. This heightened risk is primarily due to the anatomy of the molars and premolars, which have deep grooves that trap food particles and are harder to clean. Understanding this statistic is crucial for dental professionals, as it highlights the importance of preventive measures, such as the use of pit and fissure sealants, to protect against decay in these high-risk areas. This identification of risk levels emphasizes the need for regular dental check-ups and cleanings, especially in children and adolescents, who may have a higher risk of plaque buildup in these areas, further affirming the importance of preventive strategies in dental health.
