Abstract

Introduction: The aim of this study was to investigate the effect of two types of diode lasers with wavelengths 980 nm and 810 nm and Er: YAG laser on the level of surface roughness of Sandblasted, large grit, acid-etched (SLA) titanium discs.
Materials and Methods: In this in vitro experimental study, in the 2017 - 2018 years at the research center of Professor Tarabinejad and the central laboratory of Isfahan University,17 SLA titanium discs with a diameter of 2.5 and a height of 2 mm were used. The samples were divided into three groups of five for three lasers and one group of two as the control group. The first group was irradiated with Er: YAG laser, the second group with diode laser 810 nm, and the third group with diode laser 980 nm; and no intervention was done for the control group. The surface roughness was then investigated using an SPM microscope and Ra and Rq parameters. The obtained data were compared using one analysis of variance (ANOVA) and Tukey's post-hoc test. The significance level was set at α= 0.05.
Results: Analysis of the obtained data showed that there was no statistically significant difference in the mean values of Ra and Rq parameters among four groups.
Conclusion: Irradiation of diode lasers 810 and 980 and also Er: YAG, decontaminated the SLA titanium disc surfaces without damage. However, additional clinical trials will be needed to verify the results of the present study.
