Many lasers are available in the dental arena including ND/YAG, Erbium, CO2, and diodes. Each laser has a purpose and “niche” in dental treatment. “Evidence based” studies that have been done and are in progress to save teeth and implants from gum disease. The primary protocol in use today is LANAP. (Laser Assisted New Attachment Procedure). This strict protocol is the best evidence-based laser treatment available today. Studies on human volunteers using microscopic evaluation have shown LANAP to be superior to traditional techniques in promoting bone regeneration. The use of LAPIP is also a technique to save failing implants.
Multi-center human trials are in progress to compare LANAP to traditional modes of gum treatment. Plans are in the works for animal studies to evaluate the effect of the ND/YAG laser on failing dental implants and histologically (microscopically) to observe the efficacy of the LAPIP protocol in promoting bone regeneration, compared with traditional techniques.
I am currently moderating a discussion on WebMD to enhance understanding of how dental lasers work, which laser is appropriate and safe to use in dentistry, and which is the proper laser for the intended “target” tissue.
