Introduction: Oral cavity contains a plethora of microorganisms. These microorganisms have shown both beneficence and maleficence. The most common disease affecting the oral cavity not only to the human being but also for the animals was dental caries that are proved to have multi-bacterial origin. Bacterial species such as Streptococcus mutans (S.mutans), S.sanguis and Lactobacillus fermentum plays a major role in the pathogenesis of this disease. In this study, the crude extract of sargassum wightii is tested for its antibacterial efficacy against the S.mutants. Materials and Methods: The brown seaweed S. wightii was collected from the Gulf of Mannar. The samples were cut into small pieces and shade dried for five days. After drying, the samples were grounded and stored. Stock solution was prepared using soxhlet apparatus. The organic extract of the seaweed S. wightii was assayed for the antimicrobial activity against S. mutans using agar diffusion method and the result was compared with the positive control sample (Ampicillin). Results: Stock solution of S.wightii used in this study was prepared in the following grades 500, 750, and 1000 μg. It was found that zone of inhibition increased steadily as the concentration of the extract increased. Highest inhibition zone of about 23 mm was found out at the concentration of 1000 μg, whereas the control showed 38 mm. Result showed the definite antibacterial activity of S.wightii even with the crude extract. Conclusion: Majority of the treatment and preventive approaches for dental caries are based on the use of synthetic antibiotics and chemicals. Their excessive use leads to alterations in the oral and intestinal microbiome, development of resistance and other undesirable side effects. The use of natural resources or products has proven to be copious source of biologically active compounds. |
