Starting December 1, 2018, the Self-Instruction program will be exclusively available online. We will still publish Self-Instruction (S-I) exercises at the end of every corresponding General Dentistry article, but now you can pay online, test online, and receive your continuing education (CE) verification online. Earning CE has never been easier.

Exercise No. 408
Subject Code: 430
Pediatric Dentistry

The 15 questions for this exercise are based on the article, Success rates of Hall technique crowns in primary molars: a retrospective pilot study on pages 32-35. This exercise was developed by Kim Capehart, DDS, PhD, MBA, in association with the General Dentistry Self-Instruction committee.

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

  • describe the characteristics of the Hall technique;
  • assess successes and failures from the placement of stainless steel crowns (SSCs); and
  • recognize the differences between the Hall technique and the conventional technique for SSC placement.

Answers for this exercise must be received by August 31, 2018.
