Avaliação do efeito térmico do laser de diodo de alta potência e do bisturi elétrico após incisões em mandíbula de porco

Abstract

Currently, health care professionals have been using equipment to facilitate the surgery and reduce postoperative complications, being among these equipment lasers and electro cautery. The high power laser diode is used for soft tissue surgery, such as incisions in the gingiva and the oral mucosa, with little or no bleeding, because of the sealing of blood ves sels and the analgesic effect due to the sealing of terminations. The electrocautery used as thermal ablation technique produces heat by an electric current which is passed directly to target tissues, in order to achieve favorable therapeutic effects. The aim of this study was evaluate the temperature variation using such equipment during incisions in pig jaws. Linear incisions were made using a high intensity diode laser and electrocautery. The temperature during surgical incisions, using both equipment, was evaluated by thermographic analyses. The electrocautery produced a greater increase in tissue temperature compared to the high power laser. This study concluded that the use of diode laser is safer because the maximum temperature reached was lower when compared to the electrocautery.
