“…The Gram-positive bacterium Streptococcus mutans plays a crucial role in dental caries onset and progression [ 7 ], especially due to its capacity to produce organic acids and to withstand stressful conditions such as low pH. It also has the ability to synthesize large amounts of extracellular polymers from sucrose metabolization, thereby promoting supportive conditions for the adhesion and aggregation of other acidogenic and aciduric microorganisms to the biofilm [ 8 ].…”

Despite the remarkable effects of sodium hexametaphosphate nanoparticles (HMPnano) on dental enamel de-/re-mineralization processes, information on the effects of these nanoparticles on biofilms is scarce. This study assessed the effects of HMPnano, with or without fluoride (F), on the inorganic components and pH of Streptococcus mutans and Candida albicans dual-species biofilms. Solutions containing conventional/micro-sized HMP (HMPmicro) or HMPnano were prepared at 0.5% and 1%, with or without 1100 ppm F. A 1100 ppm F solution and pure artificial saliva were tested as positive and negative controls, respectively. The biofilms were treated three times and had their pH analyzed, and the concentrations of F, calcium, phosphorus, and HMP in the biofilm biomass and fluid were determined. In another set of experiments, after the last treatment, the biofilms were exposed to a 20% sucrose solution, and the biofilm pH and inorganic components were evaluated. The 1% HMPnano solution with F led to the highest biofilm pH, even after exposure to sucrose. The 1% HMPnano solution without F led to significantly higher phosphorus concentrations in comparison to all other groups. It can be concluded that 1% HMPnano and F influenced the biofilm pH, besides affecting most of the inorganic components of the dual-species biofilms.

“…In the current study, the detection of S. mutans in saliva sample was 100%. In the previous study, S. mutans was present in all of the patients with dental caries (Sounah and Madfa, 2020). S. mutans was present in all saliva samples and that there was a statistically significant link between the number of S. mutans and the DMFT score (Kishi et al, 2009).…”

To assess the frequency of streptococcus mutans (S. mutans) and its association with socio-demographic factors in patients having dental caries presenting at a DHQ hospital in rural area of Balochistan. It was a cross-sectional study conducted at the clinical setting or DHQ hospital of a rural area in Balochistan from April 2020 January 2021. About 120 patients of age 18 to 40 years of either gender presenting dental caries were included in the study using non-random consecutive sampling technique. Data regarding age, gender, ethnicity, addictions (like gutka and smoking) pH level and oral hygiene was obtained from all the participants by researcher himself. The number of S. mutans colonies (CFU) was counted using a self-illuminating binocular microscope after plates were incubated for 48 hours at 37°C. All findings were entered into a pre-designed proforma. SPSS version 23 was used to analyze data. The median age of patients with dental caries was 28 years (IQR: 21-35 years) and 83.3% of the patients were males. The median S. mutans count of all the patients with dental caries was estimated as 35 with IQR as 32 to 38. Mann-Whitney statistics showed significant difference between ethnic groups for S. mutans count (p=0.049). A weak correlation was observed between S. Mutans count and pH level (r=0.206) with statistically insignificant difference (p=0.206). Frequency of S. mutans is 100% in individuals with dental caries. S. mutan counts have a significant association with ethnicity and weak correlation with pH in saliva.

“…The bacteriological etiology of tooth decay is commonly due to the presence of S. mutans and lactobacilli microorganisms in dental plaque (1) . It was reported that S. mutans has the responsibility to initiate the carious lesion, while lactobacilli were only responsible for the caries progression (5) . The substance which can act against cariogenic bacteria such as S. mutans and lactobacilli can potentially decrease the incidence of tooth caries (6) .…”

Objectives: This study aimed to evaluate and compare the antibacterial effect of three types of chewing gum on oral streptococcus mutans and lactobacilli in school children, and the effect of them on dental debris accumulation. Subjects and Methods: A sample single blinded randomized control study included 60 healthy children age between 6-12 years with specific inclusion criteria. Three types of chewing gum were used in the present study; sugar-containing "chiclets", sugar-free "xylitol", and sugar-less "mastic". Saliva samples were collected in a sterile plain tube from participating children in the first day before taking chewing gum and then after taking chewing gum in a sterile plain tube for 3 successive days, after three days debris index was recorded. Results: There was a statistically significant reduction in S. mutans and lactobacilli count from baseline to the third day in the three studied groups. Through the intergroup comparison, there was also a statistically significant percentage of reduction of S. mutans and lactobacilli count at different time intervals, there was a statistically non-significant difference between the three studied groups according to debris index score. Conclusion: The use of sugar-free "xylitol" chewing gum has the higher significant effect on the reduction of S. mutans and lactobacilli count at different time intervals followed by sugar-less chewing gum "mastic" when compared to sugar-containing "chiclets" chewing gum.
