Most Important Operative Dentistry MCQs With Explanations

1. The following chemically bond to the tooth: A. Composite resin. B. Dental sealants. C. Glass ionomer cement. *** D. All of the above. 2. Compomer restorative materials are: A. 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. Loose enamel rods at the gingival floor of a class II amalgam cavity should be removed using : A. Straight chisel...
