ABSTRACTIntroduction: Dental caries and dental plaque are the most popular global oral health problems. The primary step of dental caries is characterized by damage of tooth surfaces  affected by acids which are by-products of sugar metabolism by a cariogenic bacteria. One of the cariogenic bacteria is Streptococcus mutans. Annona muricata is traditionally applied as an herbal remedy for various illnesses and has been recognized in a previous study as an antimicrobial agent. The aim of this study was to investigate  acid production and adhesion of ethanol extract of Soursop on Streptococcus mutans. Methods: Soursop leaf extracted by maceration using 70% ethanol solvent. The extracts obtained were tested at various concentrations. To examine the effect of ethanol extract of Soursop on acid production by S. mutans, the pH of the culture was determined using a pH meter. Inhibition of adhesion of S. mutans to the saliva-coated hydroxyapatite (S-HA) discs was quantified using colony counting on TYS20B agar plates. Results: The pH of S. mutans cultures in the presence of ethanol extract of Soursop leaf at various concentrations was higher than negative control, but there were no differences in pH value between the various concentrations of ethanol extract of Soursop leaf. Adhesion of S. mutans to S-HA discs was inhibited by various concentrations of ethanol extract of Soursop leaf. Adhesion decreased with increasing concentrations of ethanol extract of Soursop leaf, but there was not significant difference in colony count between the various concentrations of ethanol extract of Soursop leaf. Conclusions: Ethanol extract of Soursop leaf attenuates the acid production and adhesion of S. mutans to hydroxyapatite discs. Keywords: Soursop (Annona muricata); Streptococcus mutans; acid production; adhesion

Dental caries is a pathology of multifactorial origin and currently natural products are an efficient alternative treatment; The work sought to evaluate the antimicrobial activity of the Cymbopogon citratus essential oil and the citral and myrcene components against Streptococcus mutans ATCC UA159, as well as their cytotoxicity on keratinocytes and human fibroblasts. The viability effect against Streptococcus mutans on biofilms was evaluated through exposure to the three substances by using the MBEC technique-high-throughput at concentrations of 1, 0.1, and 0.01 µg/mL and chlorhexidine as positive control. The cytotoxicity of the compounds was evaluated on keratinocytes and fibroblasts through the MTT reduction technique, using 0.5 mM H2O2 as cell-death control (negative control) and ethanol 1% as vehicle control (positive control). The three substances evaluated had effects on the viability of Streptococcus mutans with mortality between 74% and 96%, without significant difference among them (p > 0.393); additionally, no cytotoxicity was evident on keratinocytes and fibroblasts in a 24-h treatment. The substances evaluated showed significant antimicrobial effects; hence, these should be studied further as potential co-adjuvants to prevent dental caries that cause minor adverse effects

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.

Streptococcus mutanspredominantly creates an acidic environment in an oral cavity. This results in dental demineralization and carious lesions. The probiotics are beneficial microorganisms that modulate the bacterial balance in the digestive system. Prebiotics are defined as nondigestible oligosaccharides that are utilized for the selective stimulation of the beneficial microorganisms. The objective of this study was to evaluate the efficacy of the prebiotics, galactooligosaccharides (GOS) and fructooligosaccharides (FOS), for enhancing the probioticLactobacillus acidophilusATCC 4356, for inhibitingStreptococcus mutans(A32-2) for the prevention of dental caries. The growth rate of theS. mutanssignificantly decreased when cocultured withL. acidophilusin the GOS-supplemented medium at 3%, 4%, and 5%. In the FOS-supplemented medium, the growth rate ofS. mutanssignificantly decreased in all concentrations when cocultured withL. acidophilus. There was no significant difference in the growth rate ofL. acidophilusin all concentrations of either GOS or FOS. It can be concluded that the growth rate ofS. mutanswas significantly retarded when cocultured withL. acidophilusand the proper concentration of prebiotics. These prebiotics have potential for a clinical application to activate the function of the naturally intraoralL. acidophilusto inhibitS. mutans.

Dental caries, the most common oral disease, is a major public healthcare burden and affects more than three billion people worldwide. The contemporary understanding of the need for a healthy microbiome and the emergence of antimicrobial resistance has resulted in an urgent need to identify compounds that curb the virulence of pathobionts without microbial killing. Through this study, we have demonstrated for the first time that 5,6,7-trihydroxyflavone (Baicalein) significantly downregulates crucial caries-related virulence phenotypes in Streptococcus mutans. Baicalein significantly inhibited biofilm formation by Streptococcus mutans UA159 (MBIC50 = 200 μM), without significant growth inhibition. Notably, these concentrations of baicalein did not affect the commensal S. gordonii. Strikingly, baicalein significantly reduced cell surface hydrophobicity, autoaggregation and acid production by S. mutans. Mechanistic studies (qRT-PCR) showed downregulation of various genes regulating biofilm formation, surface attachment, quorum sensing, acid production and competence. Finally, we demonstrate the potential translational value of baicalein by reporting synergistic interaction with fluoride against S. mutans biofilms.

Streptococcus mutans has been reported to be a major causative microorganism for oral biofilm associated with dental caries. Jasmine sambac or Arabian jasmine is a species of jasmine native to tropical and warm temperate regions particularly West and Southeast Asia. The antimicrobial activities of essential oil extracted from the flowers of J. sambac have been shown to attract researchers. Objective: To determine the anti-biofilm formation of S. mutans by mouthwash containing jasmine oil. Materials and Methods: S. mutans KPSK2, the cariogenic strain of oral streptococci was used in the study. The 24-h biofilms of S. mutans were formed on polystyrene plates treated with jasmine mouthwash. The 0.2% chlorhexidine gluconate and phosphate buffer saline mouthwash were used as a positive and negative control respectively. The amount of biofilm was quantified by crystal violet staining and spectrophotometry at an optical density of 595 nm. Results: Jasmine mouthwash showed a significant inhibitory effect on S. mutans biofilm formation by decreasing 43% of biofilm whereas that of chlorhexidine showed 71% reduction. Conclusion: The anti-biofilm formation property of jasmine mouthwash was elucidated; therefore it might be another drug of choice that can be used as an adjunct to control the oral health in the prevention of dental caries.
