Abstract
AIM: To evaluate the antimicrobial activity of PRP and PRF with and without nanosilver. MATERIALS AND METHODS: The materials were tested in powdered form is nanosilver. The nanosilver particles was mixed to form with PRP and PRF so as to placed in a wells followed the groups are experimental groups; Group I: PRP + nanosilver particles, Group II: PRF + nanosilver and control group: PRP and PRF and normal saline. Silver nanoparticles was tested at concentrations of 50 μ gram per mL. The powder was prepared for each group with identical amount of the powder (milligram/mg) and then mixed with 1 milliliter liquid. The plates are then incubated at 37°C under appropriate atmospheric conditions (80% N(2), 10% CO(2,) 10% H(2)) for 24 hours, 48 hours, and 72 hours under anaerobic conditions in a CO(2) incubator. The diameters of the zones of bacterial and fungal growth inhibition around the wells containing the test substances are then recorded after the period of incubation. The inhibitory zone determined in millimeter by measuring scale the shortest distance between the outer margin of the well and initial microbial as well as fungal growth. The experiments were performed 20 times and the mean and standard deviations of the inhibitory zones were calculated. RESULT: Platelet rich fibrin is mixed with nanosilver particles showed higher antimicrobial efficacy than platelet rich plasma with nanosilver and simple platelet rich plasma and platelet rich fibrin are equivalent when it is placed against the anaerobic bacteria E.faecalis and yeast like fungi Candida albicans, respectively. CONCLUSION: Groups presented with antimicrobial efficacy in this order- Group IV > Group II > Group III > Group I.
