| dc.description.abstract | Streptococcus viridans is the most frequently isolated bacterium from infected root
canals (63%) and the leading cause of life-threatening sub-acute endocarditis (35%). The use of 2.5%
NaOCl as a root canal irrigation material has disadvantages, it is a bad smell and taste, causing allergies,
irritating and toxic, so other alternatives are needed. The green okra fruit extract has secondary
antibacterial metabolites such as flavonoids, alkaloids, saponins, tannins, and terpenoids. Purpose:
This study aims to determine the inhibition of green okra fruit extract against S. viridans. Methods:
This research is an experimental laboratory in vitro with a post-test-only control group design.
Antibacterial test using the disk diffusion method which consisted of 5 research groups (green okra
extract with a concentration of 1,56%, 3,125%, 6,25%, 12,5%, and 2,5% NaOCl) and 4 repetitions.
The result was analyzed using non-parametric statistical tests.
Results: The average diameter of inhibition zone of each concentration of green okra fruit extract is
1,56% (0 mm ), 3,125% (0 mm), 6,25% (14,58 mm), 12,5% (18,19 mm), and 2,5% NaOCl (23,55 mm).
The Kruskal-Wallis test showed a significance value of less than 0.05 which meant that there was a
difference in inhibition in all groups. The Mann-Whitney test showed that there were significant
differences between the study groups (α<0,05), except for the green okra extract with a concentration
of 1,56% with 3,125%.
Conclusion: Green okra fruit extract (Abelmoschus esculentus) has inhibition against S. viridans at
concentrations of 6,25% (14,58 mm) and 12,5% (18,19 mm) including the strong category. | en_US |
