Exercise No. 429
Subject Code: 430
Pediatric Dentistry

The 15 questions for this exercise are based on the article Caries risk assessment on pages 12-17. This exercise was developed by Edwin T. Batchelor, DDS, FAGD, in association with the General Dentistry Self-Instruction committee.

Reading the article and successfully completing this exercise will enable you to:

  • understand the etiology and progression of dental caries;
  • understand the concepts of Caries Risk Assessment (CRA) and how its utilization can reduce caries; and
  • have a better knowledge of modalities for caries prevention and treatment.

Answers for this exercise must be received by October 31, 2019.
