ABSTRACT
PURPOSE:
To compare the biomodulatory effects of LED and ultrasound combined with semipermeable dressing in the repair of cutaneous lesions.METHODS:
Eighty-four Wistar rats were submitted to surgical injury (2.5 cm) and divided into four groups (n=21) Group I (control), Group II (LED therapy, LED), Group III (LED therapy + dressing, LED+D) and Group IV (ultrasound + dressing, US+D). At seven, 14 and 21 days, the animals were euthanized, and the specimens of interest removed for histological analysis.RESULTS:
Histological and histomorphometric analysis revealed a greater percent wound regression in animals receiving the dressing (group III 55.97; group IV 53.06), as well as a greater reduction in the inflammatory infiltrate (group III 29.14; group IV 31.71) since day 7. A later effect, with progression of the tissue repair process only after 14 and 21 days, was observed in the LED group intense fibroblast proliferation and greater collagen fiber production and organization were seen in the LED+D and US+D groups compared to the other groups.CONCLUSION:
LED combined with a dressing was more effective at accelerating in the repair of cutaneous lesions. .
