title: The effect of carbon dioxide laser on wound contraction and epithelial regeneration in rabbits.
abstract: This study was undertaken to compare objectively healing rates (in rabbits) of wounds caused by CO2 laser with those caused by scalpel. The rates of contraction and epithelialisation of standard wounds were determined with daily measurement of wound area from the time of wounding until the wound had healed. Our results demonstrate significant delays in both wound contraction (p = 0.0001) and epithelialisation (p = 0.0001) for CO2 laser-created wounds when compared to those seen in scalpel-created wounds. Normal epithelial regenerative capacities were demonstrated in the laser group despite the slow onset of epithelial migration. The appearance of the healed areas appeared comparable for both modalities.
