ABSTRACT

Spirulina is a cyanobacterium or a blue-green algae known to have a wide range of therapeutic properties. It has antimicrobial effects against Streptococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella sp, Proteus sp, and Enterobacter sp. Little has been researched on the beneficial effects of Spirulina on particular periodontopathic organisms. The objective of this study is to evaluate the antibacterial effects of Spirulina Platensis on two periodontopathic bacteria, Porphyromonas gingivalis, and Tannerella forsythia, and to compare its efficacy with that of the gold standard, Chlorhexidine.
