| Popis: |
This study was conducted in order to compare clinical and histopathological outcomes for excisional biopsies when using pulsed CO laser versus Er:YAG laser. Patients (n = 32) with a fibrous hyperplasia in the buccal mucosa were randomly allocated to the CO (140 Hz, 400 μs, 33 mJ) or the Er:YAG laser (35 Hz, 297 μs, 200 mJ) group. The duration of excision, intraoperative bleeding and methods to stop the bleeding, postoperative pain (VAS; ranging 0-100), the use of analgesics, and the width of the thermal damage zone (μm) were recorded and compared between the two groups. The median duration of the intervention was 209 s, and there was no significant difference between the two methods. Intraoperative bleeding occurred in 100% of the excisions with Er:YAG and 56% with CO laser (p = 0.007). The median thermal damage zone was 74.9 μm for CO and 34.0 μm for Er:YAG laser (p |
