Exercise No. 322
Subject Code: 017
The 15 questions for this exercise are based on the article, Marginal leakage and microhardness evaluation of low-shrinkage resin-based restorative materials, on pages 46-50. This exercise was developed by Steven E. Holbrook, DMD, MAGD, in association with the General Dentistry Self-Instruction committee.
Reading the article and successfully completing this exercise will enable you to:
- recognize the components of low-shrinkage resin-based restorative materials;
- recognize the factors that contribute to their microhardness;
- identify the advantages of reducing polymerization shrinkage in them; and
- understand how they compare to conventional materials.
