One of the limitations of the present study was that it employed an invitro lab based study design Hence the laboratory results need reconfirmation in real life situation further the study tested the anti-microbial effect of ocimum sanctum against only one periodontal pathogen i.e.actinobacillus actinomyctemcomitans however many other microorganisms have been implicated in the causation of periodontal disease including p.gingivalis and prevotella intermedia hence it is also recommended to determine the anti-microbial effct of ocimum sanctum extract against other common periodontal pathogens like p.gingivalis and prevotella intermedia to find out the spectrum of its activity
