Does a Pulsed Mode Offer Advantages Over a Continuous Wave Mode for Excisional Biopsies Performed Using a Carbon Dioxide Laser?

In contrast to previous animal studies, no significant difference was found in the widths of thermal damage zones between the CW and CF groups. The VAS values and analgesic intake were low in the 2 groups. The 2 CO2 laser modes are appropriate for the excision of intraoral mucosal lesions. A safety border of at least 1 mm is recommended regardless of the laser mode used.
