Sažetak
Abstract: Diode laser surgery is becoming widely used for oral surgical procedures. In the past, there have been few studies reporting beneficial effects of diode laser therapy. As surgical cutting proceeds, the heat generated seals small blood and lymphatic vessels reducing or eliminating bleeding and oedema. However, healing mechanisms after laser surgery depend on the laser parameters. Irrespective of the laser wavelength all soft tissue healing will be by secondary intention. It is well known that surgical site after laser surgery shows delay in healing, however, this is clinically unimportant as healing after laser surgery starts two days after the procedure. Aim: Aim of this study was to compare diode laser and conventional surgery when surgically treating oral soft tissue lesions regarding specific clinical and patient’s satisfaction parameters. Materiel & methods: Twenty nine participants with oral fibromas were involved in the study. The diagnosis was established based on clinical appearance of the lesion and confirmed by histopathological evaluation. Study group consisted of 5 men and 11 women, (age range 12-80, mean 44.3 ±21.2). Oral fibromas in the study group were treated with diode laser (Hager&Werken, DUISBURG, Germany), wavelength of 975 nm, with Fibroma removal program, power of 5W and continuous mode, using spot size 0.1-0.5 mm. Control group consisted of 6 men and 7 women, (age range 15-67, mean 45.6 ± 16.9). All fibromas in the control group were treated with conventional scalpel excision and silk sutures. Local anestethic was administered to all patients before the procedure. Three days after the surgical procedure oedema, haematoma, postoperative pain and patient’s satisfaction were assessed by the single examiner. Oedema was assessed as the presence of swollen tissue around incision line and was measured in millimetres. Haematoma was defined as the presence of blood extravasation around the incision line and was measured in millimetres as well. Post-operative pain and patient’s satisfaction were assessed using VAS. After three weeks patients were recalled again for delayed postoperative complications evaluation. Statistical analysis was performed with χ2 test for categorical and Mann- Whitney test for numerical variables. P-values lower than 0.05 were considered as significant. Results: No significant differences regarding age and gender of the participants were observed between the groups. Patients in the study group had significantly lower oedema and haematoma scores compared to the patients in the control group (p<0.05). Patients in the study group reported significantly lower pain and higher satisfaction rate compared to the patients in the control group (p<0.05). Conclusion: Based on the results of our and other studies we might conclude that diode lasers should be employed in oral surgical procedures due to coagulation effect, sterilization of the surgical site, minimal or no swelling and significantly reduced postoperative pain.
