Update in Modern Root Canal Instrumentation and Disinfection Techniques. Part 1
You will receive 2 unit(s) of continuing education credit upon successful completion of this course. The purchase price of this course is $82.00

Description:
This course divided in 2 parts is designed for the general practitioner to improve their knowledge and their endodontic skills. In this first part of the course, will start with a review of the basic biologic and instrumentation principles. This part will refresh the basic concepts, canal anatomy, patency, crown down concepts and working length determination.

Upon completion of this course, the participant should be able to:
  1. Understand the biologic objectives of root canal therapy
  2. Describe root canal anatomy, root shapes and apical root anatomy
  3. Know how to use and trouble shoot apex locators
  4. Understand the importance of effective bio-mechanical cleansing
  5. Know the methods for effective bio-mechanical cleansing
  6. Describe the basic concepts of root canal instrumentation



Abstract:
The number of NiTi rotary systems have increased at an astounding rate over the past 10 years. This course is intended to help the practitioner understand how to use mechanical NiTi instrumentation in a safe and efficient way.
