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.
