English Abstract
Continuous wave (CW) 980nm Laser soft tissue welding has been studied for full thickness incisions on the oral mucosa of the rabbit -in vivo-.
Thirty rabbits were included in the present study, they have been divided into five groups; each group consisted of six rabbits.
The schedule of the postoperative sacrificing for dissection of the groups was according to the healing process stages as follows: Group (a) rabbits were sacrificed immediately postoperatively.
Group (b) rabbits were sacrificed 24 hours postoperatively.
Group (c) rabbits were sacrificed 3days postoperatively.
Group (d) rabbits were sacrificed 10 days postoperatively.
Group (e) rabbits were sacrificed 14 days postoperatively.
Two surgical incisions have been done along the hard palate of each rabbit; the right side incisions were sutured with 3:0 silk suture, while the left side incisions were irradiated with 980nm diode laser, 0.63W as an output power, the power density was 55.681W/cm2 and 27s as an exposure time.
The clinical results of the immediately laser welded incisions showed a hemostasis of the bleeding, a well approximated incision edges and less scar formation than the sutured ones along the healing periods.
While the histopathological examination of all groups’ samples showed comparable results though it revealed a more patent inflammatory response as well as a fastened healing pattern in the irradiated incisions in comparison with the sutured incisions.
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.
