Abstract Aim of the Study: The aim of this in vitro study was to evaluate growth inhibitory efficacy of methonolic extract of the marine macro algae plant Padina gymnospora against the dental pathogens, Streptococcus mitis, Streptococcus mutans, Streptococcus salivarius, and Porphyromonas gingivalis. Methodology: A Disc diffusion assay of the extract used in this experiment to evaluate the bactericidal effect. Results: In vitro inhibitory activity of Padina gymnospora extract shows superior antibacterial properties when compared to standard antibiotics. The extracts indicated the highest zone of inhibition (14mm) in P.gingivalis and moderate inhibition zone (10mm) in S.mutans. Conclusion: P.gymnospora ethanolicic extracts posses a broad spec¬trum of activity against the bacterial strains responsible for the most common dental diseases. These primary extracts open the possibility of finding new clinically effective antibacterial compounds. Continued further research is necessary to determine the identity of the antibacterial compounds of these marine algal plants.

Key words: Dental pathogens, Disc diffusion, inhibition zone, marine algae.
