Figure 3

Histological finding of the groups at 10×10 magnification. Group 1: 1W defocused CO₂ laser irradiation. Group 2: 1W defocused CO₂ laser irradiation with absorption media. Group 3: 2W defocused CO₂ laser irradiation. Group 4: 2Wt defocused CO₂ laser irradiation with absorption media. Group 5: 3W defocused CO₂ laser irradiation. Group 6: 3W defocused CO₂ laser irradiation with absorption media. Group 7: Absorption media alone.
