The correct answer reflects the findings in dental research indicating that carious lesions will reach the outer dentin in 61% of cases. This percentage is derived from studies exploring the progression of dental caries, particularly how often they penetrate from the enamel into the underlying dentin.

The significance of this figure lies in its implications for clinical practice and preventative measures. Understanding that caries progress to the outer dentin in this proportion reinforces the need for regular dental check-ups and the importance of early detection and intervention. If cavities are not treated while still confined to the enamel, the likelihood of them reaching the outer dentin increases, which can lead to more extensive damage and the necessity for more invasive treatment options.

This percentage becomes particularly important when considering the implementation of caries management strategies aimed at remineralization and early intervention, thus supporting practitioners in managing dental caries effectively.
