Which statement accurately describes compomers?

Compomers, or composite resins modified with glass ionomer components, are designed to combine the properties of both materials. They typically exhibit some of the strength and aesthetic qualities of composites while integrating the fluoride-releasing and adhesive properties of glass ionomers. This unique combination allows compomers to bond effectively to tooth structure, providing a reliable restorative option in dentistry.

The fluoride release characteristic of compomers can help in caries prevention, which makes them particularly beneficial in pediatric dentistry and other scenarios where fluoride retention is favorable. This contrasts with the statement that they have no fluoride release, which is inaccurate. Additionally, compomers do bond to tooth structure, meaning that the assertion that they cannot bond is also incorrect.

While they do possess reasonable wear resistance, the statement regarding higher wear resistance than conventional glass ionomer is not entirely accurate. Compomers generally have improved wear characteristics compared to traditional glass ionomer materials but are still not as wear-resistant as some modern composite materials. Hence, the accuracy of the statement identifying compomers as composites with added glass-ionomer components is what establishes it as the correct choice.
