What makes a good surgical laser? A good surgical laser for cutting soft tissue must be able to (1) efficiently vaporize soft tissue, and, at the same time, (2) efficiently coagulate surgical margins. Not all laser wavelengths are suitable to comply with both requirements.

How deep does the laser cut? How deep do different laser wavelengths and pulse settings coagulate? Clearly, different settings deliver different laser-tissue effects, which must be efficiently managed and controlled by properly trained and knowledgeable surgeons.

This course focuses on the practical aspects of soft tissue laser surgery, as well as on the fundamental processes involved in the laser-tissue interaction and helps attendees learn how deep the laser beam cuts and how deep the coagulation and hemostasis extend into the surgical margins. Our hands-on participation lab is designed to be second to none in training attendees on what surgical lasers can do safely and efficiently.

Laser Curriculum

Laser Surgery and Safety Basic Knowledge Certification Curriculum for this Course has been developed by the American Laser Study Club (ALSC). The ALSC’s curriculum overcomes the known limitations of many laser dentistry courses, and includes the detailed physics of soft tissue ablation and coagulation with laser and hot tip (non-laser) devices. ALSC will provide lecture note handouts, ALSC online laser-tissue interaction knowledge exam, an option for online laser safety training and examination through the Laser Institute of America. Laser hands-on wetlab on tissue samples will include laser safety instructions and demonstrations.

Course Certificates

Course participants, who successfully complete examination, will be awarded a LASER SAFETY basic knowledge CERTIFICATE from the Board of Laser Safety of the Laser Institute of America (DISCOUNTED cost for the ALSC members), as well as a Laser Dentistry and Laser Surgery Basic Knowledge and Hands-On participation Wetlab CERTIFICATE from the American Laser Study Club (FREE for the course participants).

About the ALSC

The American Laser Study Club was founded by Peter Vitruk, PhD, MlnstP, CPhys to promote science-based laser dentistry, surgery and safety education. The ALSC is proud of its curriculum and its distinguished membership, including our honorary members Gordon J. Christensen, DDS, MSD, PhD and Rella P. Christensen, RDH, PhD, world renowned leaders in dental product research and education, who welcomed ALSC’s mission: “Peter, we congratulate you on starting a laser study club. It is greatly needed, and you are the man to do it.” Other Honorary Members of the ALSC are Charles M. Cobb, DDS, MS, PhD, Professor Emeritus, Department of Periodontics, School of Dentistry, University of Missouri-Kansas City and C. Kumar N. Patel, PhD, MS, the Inventor of the co, Laser; Recipient of National Medal of Science (1996); Member of US National Inventors Hall of Fame 2012; Professor Emeritus, UCLA. The ALSC is proud to have helped many dentists and surgeons.
