Continuous mode of operation (CW)980 nm Laser tissue welding has been studied for full thickness incisions on the oral cavity of the rabbit in vivo. Materials and Methods: Surgical incisions were done on the hard palate of the rabbits; the incisions were irradiated with 980 nm diode laser, 0.63 W as an output power and 27 s as an exposure time. Results: The immediate clinical results have shown a hemostasis of the bleeding, while the histopathological examination showed comparable results though it revealed a fastened healing pattern in comparison with the sutured incisions. Discussion: The immediately laser welded tissues was as a result of the denaturation and coagulation of the tissue proteins via the increase of the tissue temperature due to the laser-tissue photothermal interaction. Conclusion: The use of 980 nm diode laser in soft tissue welding is a successful method of wound closure in oral mucosa with the minimum side effects. |
