Microscopically-measured evaluation of dead skin and mucosa destruction produced by carbon dioxide laser– animal model-based investigation
Journal Title: Journal of Stomatology (Czasopismo Stomatologiczne) - Year 2010, Vol 63, Issue 11
Abstract
Aim of the study: To assess histopathological effects of carbon dioxide laser pulse of varying power on soft tissues.Material and methods: The study was carried out on pig heads obtained from planned slaughter. Laser Azuryt CTL 1401 was used at energies of 5, 10, 15 W per pulse emitted from two distances (1.5 and 7 cm). After the exposure skin and mucosa were excised and put into formalin. The same procedure was performed after infiltrationofbothsofttissueswith 2% lidocaine. Samples were preserved in 10% formalin, embedded in paraffin,sectionedandstained with H.E. and examined under the light microscope at x40 magnification.Threeparameterswere evaluated in each case: depth and diameter of actual tissue defects and the character of pathology in their proximity.Results: As the intensity of laser increased, histopathological changes were proportionally deeper and more extensive.Conclusions: Diminished distance between laser source and tissue resulted in deeper tissue penetration and shorter diameter of the defect.
