The effectiveness of edamame extract (glycine max l. merrill) against the inhibition of streptococcus mutans in orthodontic material

Abstract

Orthodontic appliances consist of brackets and Elastomeric Chain Generation II (ECG II). Fixed orthodontic appliances can increase the amount of oral biofilm and bacterial colonization on the tooth surface. The bracket enhances bacterial adhesion due to its high surface free energy. The Elastomeric Chain is susceptible to stretching during use which shows the presence of microporosity shaped like a honeycomb pattern due to the release of filaments when stretched. Objective: The objective of this study was to determine the power of edamame extract (Glycine max L. merril) as an antibacterial in inhibiting Streptococcus mutans (S. mutans) on metal brackets and EGC II and to determine the concentration of edamame extract which was effective in inhibiting the growth of S. mutans on metal brackets and EGC II. Research Methods: This type of research is experimental laboratory with post test only control group design. This research is divided into 3 groups, namely control group (sterile distilled water), 50% edamame extract group, and 75% edamame extract group. Observations were made by counting the number of colonies on MHA solid media using the Total Plate Count (TPC) method. Results: The results showed that the control group did not have any inhibition on the growth of S. mutans bacteria. Between the 50% and 75% groups, the one with the greatest inhibition was the 75% group. Conclusion: The conclusion of this study is that the antibacterial power of 75% concentration of edamame (Glycine Max L. merril) extract was effective in inhibiting the number of S. mutans colonies on metal brackets and EGC II
