Abstract Background: A new approach for antimicrobial agent to overcome the antibiotic resistance became the point of interest in dentistry as the occurrence and development of oral diseases. Recently, the clinical and in vitro antibacterial effect of human platelets concentrate (PCs) has been reported against different species of bacteria. Objectives: This study aims to estimate the effects of low level laser therapy on platelets rich plasma (PRP) and leukocytes against S. aureus and E. faecalis .Methodology: S. aureus and E. faecalis were treated with different platelets concentrates which were previously irradiated with 980 nm diode laser of 1.5 j/cm2 energy density. Results: PRP has a significant antibacterial activity and might be a good additive for antibiotic susceptibility. As a novel impact, activated and non-activated PCs antimicrobial properties significantly affected by low level laser treatment. Conclusion: irradiation of PRP by low level laser therapy attenuate its antimicrobial properties against treated Gram-positive pathogen |
