Root Canal Aesthetic: An Update in Modern Root Canal Obturation
You will receive 1 credit(s) of continuing education credit upon successful completion of this course. The purchase price of this course is $41.00
This lecture covers the new modern different sealers, obturation materials, instruments, machines and techniques. This course will go over the warm vertical, continuous wave and carrier-based obturation techniques, using sequential pictures and step-by-step tips.
Upon completion of this course, the participant should be able to:
- Understand the importance of root canal disinfection prior to obturation
- Understand the goals of a root canal obturation
- Describe the different endodontic sealers
- Describe the different obturation materials
- Describe the different modern root canal obturation techniques
- Identify the pros and cons of the different new modern obturation techniques
- Understand how to do the warm vertical and continuous wave obturation techniques
- Understand how to do the carrier-based obturation technique
- Know the tools needed to facilitate endodontic obturation
- Describe post-obturation coronal leakage, the use of intra-orifice plugs and the importance of a well sealing final restoration
The obturation phase of a root canal is the final step of the treatment from which we judge the quality of our disinfection on the radiograph. Thus, the aesthetic part of our treatment comes out in this final step.
