Study suggests there may be no difference between char-free and continuous-wave carbon dioxide lasers for oral mucosal biopsy


Animal studies have suggested that there is less thermal damage when excisional biopsies are performed using a carbon dioxide (CO2) laser in a char-free (CF) mode than in a continuous-wave (CW) mode. The aim of this study was to and compare the clinical and histopathologic characteristics of excisional biopsies performed with CW or CF CO2 [read the full story…]
