Abstract

Purpose: It has been demonstrated that diode lasers can be an effective alternative in oral soft tissue surgeries. This study aimed to clinically evaluate the tissue healing around the gingival former of dental implants following the uncovery of areas with different diode laser wavelengths. Materials and Methods: This study was conducted on 72 implants (in the Periodontology Department of the Faculty of Dentistry, Jundishapur University of Medical Sciences in Ahvaz, Iran, in 20152016) with two different diode laser wavelengths (940 and 810 nm). The samples were randomly assigned to two groups of 36 implants, including experimental and control. The experimental group was based on the second stage of implant uncovery with a 940nm diode laser, and the control group included the second stage with an 810 nm diode laser. Indicators such as the need for local anesthesia and the amount of anesthesia injected during surgery, the duration of surgery, the amount of bleeding during surgery, pain, inflammation, edema, and the color of the gingiva in the surgical area, were compared in two study groups during surgery. Results: The independent ttest showed no significant difference in the average duration of surgery in the two groups (31.3 and 37.6 seconds in the 940nm and 810nm wavelength of the diode laser, respectively, P=0.073). On day zero and day seven after surgery, pain intensity with 810nm diode laser wavelength was higher than with 940 wavelengths. The average amount of anesthesia injected during surgery of the surgical group with a wavelength of 940 nm was significantly lower than that of the 810nm diode laser. No bleeding was observed in both surgery groups. Conclusion: The 940nm diode laser had better results than the 810nm in the second stage of implant uncover. © 2025 Elsevier B.V., All rights reserved.
