A comparative study on the effect of YAG: Er and 089 nm Diode laser irradiation on the attachment of osteoblast cells on the surface of dental implant fixtures

Abstract

Background and Aim: Nowadays, lasers are the focus of attention as a new treatment in dentistry. One of the applications of lasers is their use in implant dentistry. The present study aimed to compare the effect of YAG: Er and 089 nm Diode laser irradiation on the attachment of osteoblast cells on the surface of dental implant felxtures. Materials and Methods: In the present study, 36 titanium implants were divided into three groups of 12. Twelve implants were irradiated with Er: YAG laser and 12 implants were irradiated with a diode laser, and 12 implants were not irradiated as a control group. Osteoblast cells were cultured on the samples, and the attachment and viability rate of these cells were examined by SEM electron microscopy and MTT test. Results: There was no significant difference between laser irradiated implants groups and the control group in terms of cell viability rate based on the MTT test.
