Antibacterial Effectivity Test of Tin Leaf Extract (Ficus Carica Linn.) Towards Streptococcus Mutans Bacteria on Dental Plaque: In-Vitro Study

Dental plaque is the main etiology of periodontal disease, such as gingivitis and periodontitis. Dental plaque contains a variety of bacteria, one of which is Streptococcus mutans. The purpose of this study was to determine the effectiveness of tin leaf extract toward the growth of Streptococcus mutans bacteria on dental plaque. This research is an experimental laboratory study, starting with the production of tin leaf extract in 5 concentrations and followed by an antimicrobial growth test with a disc diffusion technique. Data collection was carried out by measuring the inhibition zone diameter using a caliper by the researchers. After doing a statistical test with the Kruskal-Wallis test, the results obtained ap = 0.002 (p<0.05). This shows that the tin leaf extract is effective in inhibiting the growth of Streptococcus mutans bacteria, where the higher the concentration of the tin leaf extract, the wider the diameter of the inhibitory zone formed.
