DT-08 Beyond the Hype: Three Years of Independent Research on What Laser Irrigation Can and Cannot Do

CE Hours: 1.0

Description: Laser activated irrigation continues to generate excitement in endodontics, but its clinical value requires careful, unbiased evaluation. This session will present three years of independent studies investigating both the advantages and limitations of laser use in root canal treatment. Topics will include the impact of early application during crown down instrumentation, effectiveness in smear layer removal, ability to enhance irrigant penetration into complex anatomies such as isthmuses and lateral canals, its influence on obturation, the potential for irrigant extrusion, and its role in the removal of residual gutta percha during retreatment. By presenting data from a series of independent projects, this session will move beyond speculation and provide participants with a balanced understanding of what laser irrigation can and cannot deliver. Attendees will come away with practical insights to guide evidence based decision making about integrating lasers into endodontic practice, ensuring their use is grounded in science rather than marketing.

Learning Objectives:  

• Identify the advantages of laser activated irrigation in enhancing canal cleaning, including smear layer removal, irrigant penetration into complex anatomies, residual gutta percha removal, and obturation quality.
• Recognize the limitations of laser activated irrigation in achieving these same outcomes and compare its performance with other activation methods.
• Evaluate the risks associated with laser irrigation, including the potential for irrigant extrusion, and integrate this knowledge into evidence based clinical decision making.
