A CO 2 laser (Coherent Medical Model 400) was used to irradiate the gingival tissue of a cynomolgous monkey to determine laser effects on the epithelium and underlying connective tissue. A focal length of 400 mm and a 10‐watt power setting at 0.2‐ and 0.5second exposure was used. Biopsy results indicated that a 0.2‐second duration of CO 2 laser irradiation was inadequate to completely de‐epithelialize the gingival tissue. A 0.5‐second exposure exhibited complete epithelial destruction with little or no disturbance of the underlying connective tissue layer and viable connective tissue 1.0 mm below the impact site.
