Objectives
It was the aim of this study to determine thermal and histologic events resulting
from soft tissue incision with three CO2 lasers: one emitting light energy via a hollow waveguide at 9.3 μm; the others emitting
light energy at 10.6 μm, one via a hollow waveguide, the other through an articulated
arm delivery system.
Study design
Thirty standardized incisions were made in the oral mucosa of pig's mandibles with
three different lasers at actual power levels of 1,4 and 12 W. Thermal events were
recorded with thermocouples, and a histologic examination was performed to determine
vertical and horizontal tissue damage as well as incision depth and width.
Results
Thermal and histologic results were related to parameters and beam characteristics
rather than wavelength.
Conclusion
In addition to wavelength, many variables can contribute to the surgical characteristics
of a laser.
