What is a contraindication for the use of resin in dental restoration?

The option that highlights a contraindication for the use of resin in dental restoration is linked to the scenario where there is a high risk for multiple caries. In this context, restorative materials must provide durability and longevity, especially in patients who have a high susceptibility to caries. Resin materials, while esthetic and versatile, may not offer the same level of durability or resistance to breakdown under the forces associated with high caries risk. In such cases, other materials may be preferred to ensure that the restorations can withstand the potential stress and prevent future restorative failures associated with high caries incidence.

Moreover, the other scenarios listed do not present the same level of concern regarding resin utilization. Class I restorations are typically well-suited for resin materials. Pediatric use on first molars, although requiring careful consideration due to the potential wear of resin under biting pressures, does not inherently contraindicate resin use. Likewise, while large Class II restorations present challenges for resin due to possible polymerization shrinkage or stress, they are not automatically contraindicated; they can be placed successfully with appropriate techniques.

Hence, the selection of resin in cases of high caries risk emphasizes the importance of material properties and their alignment with patient needs, ensuring that restorations are effective and
