Glass ionomer with polymer components B. Resin systems with fluoride containing glasses. *** C. Composite resin for cervical restorations only. Explanation: The composition of compomers is similar to that of a dental composite however it has been modified, making it a polyacid-modified composite. This results in compomers still requiring a bonding system to bond to tooth tissue. Although the name compomer implies that the material possesses a combination of characteristics of both composite and glass ionomers, these materials are essentially polymer-based composites that have been slightly modified to take advantages of the potential fluoride-releasing behavior of glass ionomers. 3.
