“…Tosun et al [30] compared the antimicrobial effect of Er:YAG, diode, and CO 2 lasers in the decontamination of titanium disks infected with Staphylococcus aureus (S. aureus). The CO 2 laser has eliminated 100 % of the bacteria in the power of 6.0 W and frequency of 20 Hz with pulse duration of 10-ms application for 10 s using a tip with 0.8 mm in diameter.…”

Temperature evaluation of dental implant surface irradiated with high-power diode laser

The prevalence of peri-implantitis and the absence of a standard approach for decontamination of the dental implant surface have led to searches for effective therapies. Since the source of diode lasers is portable, has reduced cost, and does not cause damage to the titanium surface of the implant, high-power diode lasers have been used for this purpose. The effect of laser irradiation on the implants is the elevation of the temperature surface. If this elevation exceeds 47 °C, the bone tissue is irreversibly damaged, so for a safety therapy, the laser parameters should be controlled. In this study, a diode laser of GaAsAl was used to irradiate titanium dental implants, for powers 1.32 to 2.64 W (real) or 2.00 to 4.00 W (nominal), in continuous/pulsed mode DC/AC, with exposure time of 5/10 s, with/without air flow for cooling. The elevation of the temperature was monitored in real time in two positions: cervical and apical. The best results for decontamination using a 968-nm diode laser were obtained for a power of 1.65 and 1.98 W (real) for 10 s, in DC or AC mode, with an air flow of 2.5 l/min. In our perspective in this article, we determine a suggested approach for decontamination of the dental implant surface using a 968-nm diode laser.

“…We also believed that the lack of calibration in the Leja research [30] has led to this difference. Some authors do not give the necessary attention for the temperature limit to be respected, or the laser calibration, which can be dangerous [21].…”

“…91 In vitro studies indicate that several lasers have the ability to achieve 100% bacterial elimination without damaging the implant surface. 92 However, nonsurgical laser therapy has been shown to be minimally successful (decreases in clinical attachment level and pocket depths generally less than 1 mm) in a systematic review. 93,94 When used appropriately, nonsurgical laser therapy is beneficial in reducing mucosal inflammation, and to some extent, PD around implants diagnosed with peri-implantitis.…”

“…The application of laser systems has been suggested as a potential adjunctive or alternative to conventional treatment approaches [6,7]. CO 2 lasers have been shown to effectively remove bacterial plaque from titanium surfaces and can restore its biocompatibility without damaging these surfaces [8,9]. Tuson et al [8] demonstrated that the CO 2 laser eliminated 100 % of the bacteria at 6 W, 20 Hz, and a 10-ms exposure time/pulse with a 10-s application period (0.8-mm spot size).…”

Bacterial biofilms have been identified as the primary etiological factor for the development and progression of peri-implantitis. Lasers have been shown to remove bacterial plaque from titanium surfaces effectively and can restore its biocompatibility without damaging these surfaces. Therefore, the aim of this study was to evaluate the responses (i.e., the cell viability and morphology) of human osteoblast-like SaOs-2 cells to sandblasted, large grit, and acid-etched (SLA) titanium surfaces irradiated by CO2 lasers at two different power outputs. A total of 24 SLA disks were randomly radiated by CO2 lasers at either 6 W (group 1, 12 disks) or 8 W (group 2, 12 disks). Non-irradiated disks were used as a control group (four disks). The cell viability rates of the SaOs-2 cells in the control and study groups (6 and 8 W) were 0.33 ± 0.00, 0.24 ± 0.11, and 0.2372 ± 0.09, respectively (P < 0.6). Cells with cytoplasmic extensions and spreading morphology were most prominent in the control group (141.00 ± 29.00), while in the study groups (6 and 8 W), the number of cells with such morphology was 60.40 ± 26.00 and 35.20 ± 5.40, respectively (P < 0.005). Within the limits of this study, it may be concluded that the use of CO2 lasers with the aforementioned setting parameters could not be recommended for decontamination of SLA titanium surfaces.
