Abstract
<h3>Objectives</h3> This experimental study aimed to evaluate the effects of 660 nm laser photobiomodulation, ozone therapy, and ozonized oil on the thermal coefficient of the tissue through infrared thermography in cutaneous wounds of rats. <h3>Study Design</h3> This research was approved by the Ethics Committee (67/2019). Forty rats were distributed in 4 groups of 10 rats each, including control, laser, ozone gas, and ozone oil groups. Each group was divided into subgroups of 5 rats, which were photographed with infrared thermography on days 5 and 10 after skin surgery. <h3>Results</h3> There was a reduction in the mean temperature in the wounded area of the control group, with greater variation in the groups submitted to therapies on the first day. On day 5, the groups treated with biomodulative therapies had lower average temperatures than the control group, especially the ozone gas group (<i>P</i> < .05). Ten days after surgery, there was no significant difference in the thermal coefficient between the groups (<i>P</i> > .05), except for the ozone gas group, which had an average higher temperature (35.1°C). <h3>Conclusions</h3> The use of thermograms can be useful to monitor the microcirculation pattern during tissue repair.
