ANTIBACTERIAL EFFECT OF VIRGIN COCONUT OIL ON (ACTINOMYCES SP.) THAT CAUSES DENTAL BLACK STAIN IN CHILDREN
Keywords:Actinomyces sp, Dental black stain, Virgin coconut oil
Â Objective: This study aimed to assess the effectiveness of virgin coconut oil (VCO) as a natural antibacterial agent to reduce the viability of the chromogenic bacteria Actinomyces sp., which causes dental black stains.
Methods: Actinomyces sp. was isolated from the saliva of a child diagnosed with black stain. Each streak of bacteria was cultured on a selective medium Actinomyces agar and confirmed visually and through a gram staining procedure. Each bacterial culture was exposed to VCO in concentrations of 12.5%, 25%, 50%, and 100%. Afterward, viability testing with a methyl-thiazolyl-tetrazolium assay was conducted, and the results were read using an enzyme-linked immunosorbent assay reader.
Results: The reduction of bacterial viability of Actinomyces sp. showed a significant difference between the negative control group and the groups treated with various concentrations of VCO 12.5%, 25%, 50%, and 100%.
Conclusion: The minimum concentration of VCO necessary to kill Actinomyces sp. is VCO 12.5%.
