What percentage of caries in primary teeth are found in the pits and fissures of molars?

The percentage of caries in primary teeth found in the pits and fissures of molars is indeed significant, and the correct choice reflects substantial evidence from dental studies. Research indicates that about 44% of carious lesions in primary molars are located in these anatomical areas, highlighting the vulnerability of pits and fissures to decay. This high percentage underlines the importance of preventive measures like pit and fissure sealants, as they serve to minimize the risk of caries development in these specific regions. The complexity of the pits and fissures creates an environment where plaque can accumulate more easily, which contributes to the higher caries incidence in these sites compared to the smooth surfaces of teeth. Therefore, the choice indicating 44% aligns with this understanding of dental health and the prevalence of decay in primary teeth.
