In vitro Evaluation of the antibacterial activity of Platelet-rich Plasma against Selected Oral and Periodontal Pathogens

Despite the availability of a wide range of antibiotics, bacterial infections are among important challenges for the healthcare system. Therefore, the introduction of new antimicrobial preparations such as platelet-rich plasma (PRP) could be suggested theoretically as a preventive measure for bacterial infections. We aimed to evaluate the in vitro antibacterial activity of PRP against three common oral bacteria.
In vitro antibacterial activity of PRP against Streptococcus Mitis, Streptococcus Mutans, and Neisseria Lactamica as three common oral/dental bacteria was determined by disc diffusion method. Baseline antibacterial activity was assessed by measuring the diameter zone of inhibition after 24 hours of incubation at 37 °C.
PRP had strong in vitro antibacterial activity against Streptococcus Mitis, Streptococcus Mutans and Neisseria Lactamica with the mean zone of inhibition diameters of 6.73±0.52, 5.8±0.43 and 6.67±0.43 mm, respectively.
PRP is an effective antibacterial agent along with conventional antibiotic treatments against oral and periodontal infections.
