Exercise No. 405
Subject Code: 149
Multi-Disciplinary Topics

The 15 questions for this exercise are based on the article Comparison of the effects of sodium bicarbonate jet prophylaxis on blood pressure in normotensive individuals and patients with controlled hypertension: a controlled clinical trial on pages 19-23. This exercise was developed by Riki Gottlieb, DMD, MS, FAGD, in association with the General Dentistry Self-Instruction committee.

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

  • recognize the potential effect of jet prophylaxis on blood pressure (BP);
  • review the existing physiological pathway of BP changes in response to jet prophylaxis treatment;
  • understand the impact of sodium bicarbonate jet prophylaxis on normotensive and hypertensive patients.

Answers for this exercise must be received by June 30, 2018.
