Laser-Tissue Interaction Short Video Review – Soft-Tissue Laser Education

Peter Vitruk, Ph.D., founder of the American Laser Study Club (ALSC), presents a short review of laser-tissue interaction as it applies to laser surgery in vascular tissue, including dentistry and other soft-tissue surgeries.

The video is a valuable resource for dentists and medical professionals interested in performing frenectomy (tongue-tie release) and other soft-tissue procedures. It delves into the nuances of laser-tissue interaction and showcases side-by-side video comparisons of different laser types, including Near-IR diode, Nd:YAG, Mid-IR Erbium, and IR CO2 lasers, performing a frenectomy. This comparative approach provides a practical perspective on the effectiveness and application of each laser type in soft-tissue surgeries.

Some of the questions answered in this presentation include:

  • What defines a GOOD soft-tissue surgical laser?
  • What defines the differences between ABLATIVE and NON-ABLATIVE lasers?

Surgical and dental laser wavelengths discussed in this presentation include:

  • Near-IR diode and Nd:YAG lasers (circa 1,000 nm)
  • Mid-IR Erbium lasers (circa 3,000 nm)
  • IR CO2 lasers (circa 10,000 nm)

Side-by-side laser frenectomy comparison in this video:

  • Diode laser: Slowest, good for deep hemostasis, but limited cutting ability.
  • Nd:YAG laser: Slow, painful, but good for hemostasis.
  • Erbium laser: Fastest, but poor hemostasis.
  • CO2 laser: Excellent balance of fast, precise cutting and effective hemostasis.


The best laser in soft-tissue dentistry depends on the desired outcome:

  • Fast cutting: Erbium laser (but requires additional hemostasis measures)
  • Balanced cutting & hemostasis: CO2 laser
  • Controlled bleeding: Diode and Nd:YAG lasers (slowest and limited cutting)
