Laser-assisted endodontics is emerging as one of the more important technologies in the management of endodontic disease. Much confusion exists as to which lasers are the most efficacious and conflicting ideas have emerged on how to apply the laser energy within root canal systems. To fully comprehend laser-assisted endodontics, a sound knowledge is required of laser physics and safety as well as the mechanism of action of lasers within confined root canal systems. Further understanding is necessary of fluid dynamics within open and closed systems and the consequences of imparting a high velocity to irrigating solutions, with the potential to extrude these irrigants into periapical tissues.
This lecture will review these concepts and apply them to clinical endodontics. An evidence based, laser-assisted treatment protocol will be presented that maximizes deep dentinal cleaning and disinfection, while maintaining foraminal patency, facilitating canal shaping and promoting drainage and decompression of periapical tissues. By re-thinking treatment concepts and putting to rest many of the dogmas that have governed endodontics for generations, the introduction of this innovative treatment paradigm will enhance success while significantly reducing stress and improving productivity for the endodontist.
After completing this course, participants will be able to:
- Discuss the role of biofilms in apical periodontitis and the limitations of current treatment protocols in complex root canal systems.
- Describe how lasers work and their role in Radial Apical Cleansing – a new protocol for the management of root canal systems.
- Explain that laser-assisted endodontics is not just about disinfection but also plays a critical role in the management of other treatment challenges.
- Enhance the endodontic experience for the dentist and identify the benefits of this new treatment paradigm.
