The demineralization of dental hard tissues can be caused by dental plaque. Dental plaque contains various components, especially bacteria attached to the extracellular matrix. Streptococcus mutans (S. mutans) has extracellular glucan as adhesin that is important in the attachment mechanism of tooth surface. The natural substance can be used for preventing plaque formation by inhibiting the attachment of S. mutans. Soursop plant has been used in treating various diseases. The leaves of the soursop (Annona muricata L.) are used as a material to inhibit potential attachment of bacteria S. mutans. Common surfaces that is used in adhesion testing is hydroxyapatite (HA). The aim of this study was to evaluate the effect of ethanol extract of soursop leaf (EESL) on the adhesion of S. mutans ATCC 35668 to HA discs. Soursop leaves were extracted by the maceration method using 70% ethanol. The experiment was carried out by analyzing the inhibition adhesion of S. mutans ATCC 35668 on HA discs after incubation with different concentrations of soursop leaf extract. The concentrations of extract tested were: 150; 125; 100; 75; and 50 mg/ml. Chlorhexidine 0.2% was used as a positive control while DMSO 5% was used a negative one. Data were evaluated by One Way Anova. This study statistically showed significant differences of S. mutans colony count between groups (p<0.05).The results of a post hoc Dunnett T3 test showed that the 2 highest concentrations of extract (125 and 150 mg/ml) reduced S. mutans adhesion on HA discs.The obtained results showed that ethanol extract of soursop leave inhibits the adherence of S. mutans to the HA disc.

Streptococcus mutans is the major cause of dental plaque and is often associated with biofilm formation. The aim of this study is to evaluate the activity of a hydrosoluble derivative of chitosan against S. mutans biofilms in vitro and in vivo. Strains of S. mutans were isolated from the dental plaque of 84 patients enrolled in the study. The antibacterial activity of chitosan was determined by broth microdilutions. The effect of chitosan at different concentrations and exposure times on S. mutans biofilms at different phases of development was assessed by a clinical study using the classical “4-day plaque regrowth” experiment in adult volunteers. The MIC values of chitosan were between 0.5 and 2 g/L. Compared to distilled water, the chitosan solution significantly decreased the vitality of plaque microflora (p≤0.05). Chlorhexidine, used as a positive control, reduced vitality even further. The results showed that S. mutans in the adhesion phase (4 h) was completely inhibited by chitosan at any concentration (0.1, 0.2, 0.5XMIC) or exposure time investigated (1, 15, 30, 60 min), while S. mutans at successive stages of accumulation (12–24 h) was inhibited only by higher concentrations and longer exposure times. These data confirm the effective action of chitosan against S. mutans biofilms.

Annona muricata L. is widely known throughout Indonesia as having great potentials as an antidiabetic agent. This study aimed to evaluate the antihyperglycemic effectiveness of ethanol extract 96% from soursop leaves and to compare its effects to metformin and insulin aspart injection as antidiabetic agents. This was a cross-sectional experimental study with random sampling approach which was performed at Phytochemistry and Biopharmacy Laboratory, Faculty of Pharmacy, Hasannudin University, Indonesia, from February 17 to March 3, 2020. Twenty-four Mus musculus subjects induced by streptozotocin were divided into six groups, which received 96% ethanol extract from Annona muricata in various doses. The extract was produced using the maceration process. The fasting blood sugar level was measured using the point of care testing (POCT) method, and data collected were then analyzed using a univariate approach. Results showed that the average fasting blood glucose level (FBG) was decreasing with increasing doses (5 g/kgBW=127 mg/dL, 10 g/kgBW =114 mg/dL, and 15 g/kg BW=97.75 mg/dl with a p-value of 0.000 based on repeated ANOVA. When compared to the positive control 1 (metformin), the decrease in FBG level in this control group (70.67 mg/dL) was better than in the group that received ethanol extract from Annona muricata L. In subjects in positive control 2 (insulin aspart), the average FBG level remained high, which was 473 mg/dL. Hence, 96% ethanol extract of Annona muricata L. can effectively lower fasting blood glucose in Mus musculus.

Objectives: To detect the presence of Streptococcus mutans and Streptococcus sobrinus in dental plaque of children from Cartagena and correlate it to dental caries precavity stages, applying a standardized PCR-based technique for epidemiological purposes. Methods: Descriptive study using a non-probabilistic sample of 50 children between 3 and 5 years of age, preschoolers from a Caribbean population in Colombia. Criteria for selection were that children should exhibit plaque accumulations on the surface of the cervical margins of the rearmost molars, and placed in one of two study groups: carious lesions and sound surfaces. Dental plaque samples from both groups were subjected to molecular analysis and statistical analysis was applied to determine the difference between the two groups using the frequencies of presence of S. mutans, S. sobrinus or both in the two groups applying Fisher’s exact test for association between the presence of microorganisms and the state of the tooth surface from where the dental plaque was taken. Results: The frequency of S. mutans in carious lesions was 76% and 24% in healthy surfaces. The frequency of S. sobrinus in carious lesions was 81.9% and 18.1% in caries-free surfaces. There was statistical significance between the presence of S. mutans and the presence of caries (p=0.001) and between the presence of S. sobrinus (p=0.02) and the presence of caries. There was no statistical significance between the presence of caries and the simultaneous presence of both microorganisms (p=0.08). Conclusions: The presence of S. mutans and S. sobrinus in dental plaque samples is highly prevalent and associated to non cavitated carious lesions, being the molecular identification of these microorganisms by PCR a sensitive, fast, and easy to use detection method for the mutans group of oral bacteria.
