Abstract

The aim of our study was to compare biolgic effects such as tissue damage and regeneration in rat skeletal muscle after CO₂ laser application with pulses of constant energy density, but with varying power and exposure time. We used three different laser conditions: 20 W by 0.5 s, 10 W by 1.0 s and 5.0 W by 2.0 s, all having the same energy density (10 joules in a constant area). The animals were sacrificed immediately after laser application, and after 1, 4, 7, 15 and 21 days. Tissue damage produced by the CO₂ laser with high power provokes more profound craters with less tissue damage at the margins. As shown by lesser tissue carbonization, fewer foreign body giant cell granulomas and less tissue fibrosis and, on the other hand, an accelerated regeneration of muscle tissue.
