Background: Dental caries is one of the most common infectious diseases and often occurs in the community caused by bacteria. Attached bacteria in the tooth surface for a long time will form a biofilm and will lead to demineralization characterized by damage in the structure of the tooth enamel. The bacteria that cause dental caries and can form biofilms is Streptococcus mutans. The bacteria inside biofilms are more resistant to antibacterial agents. Flavonoids in mangosteen pericarp extract can be a cleaner alternative for the anti-biofilm cavity that has properties against Streptococcus mutans. Purpose: To determine the activity of flavonoids in mangosteen pericarp extract at a certain concentration against Streptococcus mutans bacteria. Methods: This study was a laboratory experimental study with a post-test only control group design. Streptococcus mutans were diluted according to the Mc Farland dilution standard 106 in Tryptic Soy Broth (TSB) medium and put in a flexible U-bottom microtiter plate. Then it was incubated for 5x24 hours and checked using crystal violet simple staining to see the formation of biofilms. Flavonoid extract of mangosteen pericarp performed serial dilution in a concentration of 100%, 50%, 25%, 12.5%, 6.25%, 3.125%, 1.56%, and 0.78% was added, and the incubation process were conducted for 1x24 hours. OD (Optical Density) readings were done with a wavelength of 595 nm. Results: There was a significant difference between the test groups and the positive control group. The concentration of 100% had the anti-biofilm activity and showed the value of the highest percentage of inhibition, whilst the concentration of 0.78% showed a minimum biofilm inhibition concentration. The results were demonstrated by a statistical analysis test. Conclusion: Flavonoid extract of mangosteen pericarp at a certain concentration has anti-biofilm activity against Streptococcus mutans biofilm.

Abstract Background Streptococcus mutans (S. mutans) is one of the main cariogenic bacteria for caries. It was found that the clinical strains of S. mutans isolated from caries active population have stronger cariogenic ability than the isolates from caries-free (CF) people. Previous studies have found that curcumin can inhibit biofilm formation of S. mutans UA159. The objective of this study is to explore the antibiofilm effect of curcumin on the clinical isolates of S. mutans from severe early childhood caries(SECC). Results The isolates from SECC group had more biomass than CF group (t = 4.296, P < 0.001). The acidogenicity and aciduricity of the strains from two groups showed no significant difference. After treatment with curcumin, the viability of biofilm was reduced to 61.865% ± 7.108% in SECC and to 84.059% ± 10.227% in CF group at 24 h (P < 0.05). The net reduction of live bacteria and total bacteria in the SECC group was significantly higher than that of the CF group (live bacteria t = 3.305, P = 0.016; total bacteria t = 2.378, P = 0.045) at 5 min. For 24 h, the net reduction of live bacteria and total bacteria in the SECC group was significantly higher than that of the CF group (live bacteria t = 3.305, P = 0.016; total bacteria t = 2.378, P = 0.045). The reduction of biofilm thickness reduced significantly in 5 min (t = 4.110, P = 0.015) and in 24 h (t = 3.453, P = 0.014). Long-term (24 h) curcumin treatment inhibited the amount of EPS in SECC group from (25.980 ± 1.156) μm3/μm2 to (20.136 ± 1.042) μm3/μm2, the difference was statistically significant (t = 7.510, P < 0.001). The gene of gtfC, gtfD, ftf, gbpB, fruA and srtA in the CF group and the gtfB, gtfC, gtfD, ftf, gbpB, srtA in SECC group were respectively reduced after 5 min curcumin treatment. After 24 h treatment, the gtfB, gtfC, gtfD, ftf, gbpB, fruA and srtA in both two groups were downregulation, all the differences were statistically significant. Conclusions Curcumin has antibiofilm activity on clinical strains of S. mutans, especially for those isolated from SECC.

The chemical composition of propolis varies according to factors that could have an influence on its biological properties. Polyphenols from propolis have demonstrated an inhibitory effect onStreptococcus mutansgrowth. However, it is not known if different years of propolis collection may affect its activity. We aimed to elucidate if the year of collection of propolis influences its activity onStreptococcus mutans. Polyphenol-rich extracts were prepared from propolis collected in three different years, characterized by LC-MS and quantified the content of total polyphenols and flavonoids groups. Finally, was evaluated the antibacterial effect onStreptococcus mutansand the biofilm formation. Qualitative differences were observed in total polyphenols, flavones, and flavonols and the chemical composition between the extracts, affecting the strength of inhibition of biofilm formation but not the antimicrobial assays. In conclusion, chemical composition of propolis depends on the year of collection and influences the strength of the inhibition of biofilm formation.

Streptococcus mutans is a commensal bacteria of the oral cavity, particularly found in dental plaque attached to the tooth surface, and can also found in the saliva, buccal mucosa, tongue, and the gingival sulcus. Clove cigarette contains the clove oil used worldwide as a herbal remedy for a variety of health disorders due to its antibacterial, antifungal, and antiviral properties. The purpose of this study was to determined the antibacterial effect of the clove oil contained in the clove cigarette towards Streptococcus mutans as a cariogenic bacteria. The research was an experimental laboratory, which tested the sensitivity of the Streptococcus mutans bacteria taken from the saliva of 10 clove cigarette smokers towards the clove oil extract of the clove cigarette in-vitro by using the Kirby-Bauer method. The study showed that the clove oil extract of the clove cigarette which contained eugenol has antibacterial towards the growth of Streptococcus mutans, and there was a difference of the antibacterial activity between clove oil extracted from minced and combusted clove cigarette. The conclusion of this study was the clove oil extracted from minced clove cigarette had a better antibacterial effect than the combusted clove cigarette.

Biofilm Community

The current theory for dental decay, the ecological plaque hypothesis, states that the onset of disease follows unfavourable disruption of the dynamic balance between the host and the microbial biofilm community at local sites. Inherent in this theory is the concept that cariogenic bacteria, such as Streptococcus mutans, can be present in health, but at levels that are not clinically relevant and that disease can be controlled not only by targeting pathogens but also by interfering with the factors responsible for driving the deleterious shifts. Such theories require an holistic or Systems Microbiological approach to study disease, as they are not tractable by traditional approaches alone. A 2004 report by the American Academy of Microbiology emphasised the technical bottlenecks associated with the systems? approach, including the need to obtain meaningful quantitative proteome data.
