Update in Modern Root Canal Instrumentation and Disinfection Techniques. Part 2
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 is designed for the general practitioner to improve their knowledge and their endodontic skills. In this second part most new rotary systems and reciprocating systems will be presented and discussed with the participants. A review of file separation mechanisms will also be given along with an explanation of file removal techniques used by most endodontists.

Learning Objectives:
Upon completion of this course, the participant should be able to:
  1. Know the difference between endodontic motors available on the market
  2. Know the different NiTi file systems available on the market
  3. Understand effective rotary nickel-titanium file utilization and prevention of iatrogenic events
  4. Know how NiTi file fractures occurs and how to prevent them
  5. Know the separated instrument removal techniques used by endodontists and their limitations
  6. Know how to assess what NiTi file systems works best in your hands


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. This lecture will update dentists with the new NiTi metal treatments, design changes and will review most new endodontic systems.
