Streptococcus mutans is one of cariogenic microorganisms associated with tooth decay. According with the hypothesis of the ecological plaque, dental caries is the consequence of changes in the. Dental caries and dental plaque are among the most common diseases worldwide, and are caused by a mixture of microorganisms and food debris.

Specific types of acid-producing bacteria, especially Streptococcus mutans, colonize the dental surface and cause damage to the hard tooth structure in the presence of fermentable carbohydrates e.g., sucrose and by: Streptococcus mutans is one of cariogenic microorganisms associated with tooth decay.

According with the hypothesis of the ecological plaque, dental caries is the consequence of changes in the natural balance in the dental plaque microflora (oral. Assessment of Relationship between Streptococcus mutans, Dental Caries and TGF-β Streptococcus mutans is an important species in oral microflora and its components have been found to stimulate production of cytokines in dental caries.

The aim of this study was to evaluate TGF-β in patients with S. mutans. Seventy samples were selected during.

Virulence Factors of Streptococcus mutans Related to Dental Caries. March ; DOI: /intechopen In book: Staphylococcus and Streptococcus Select ion of ou r books. dental plaque in order to determine which species cause it to decay and facilitate formations of dental caries.

Although old hypotheses have been modified and study techniques enhanced, close to all researchers would agree the main species responsible is a bacteria called.

Streptococcus mutans (Figure 2). Figure 1: The structure of the tooth. Early acquisition of mutans streptococci and dental caries Early acquisition of MS is a major risk factor for early child-hood caries14 and future caries experience Alaluusua and Renken15 performed longitudinal assessment for MS and dental caries in children aged 2 to 4 years.

Children who. Nanocatalysts promote Streptococcus mutans biofilm matrix degradation and enhance bacterial killing to suppress dental caries in vivo Biomaterials.

Sep; doi: /erials   Dental caries in very young children may be severe, result in serious infection, and require general anesthesia for treatment.

Dental caries results from a shift within the biofilm community specific to the tooth surface, and acidogenic species are responsible for caries. Streptococcus mutans, the most common acid producer in caries, is not always present and occurs as part of a complex.

In the case of dental caries, replacement Streptococcus mutans and dental caries book has involved construction of an effector strain called BCS3-L1, which was derived from a clinical Streptococcus mutans isolate. Recombinant DNA technology was used to delete the gene encoding lactate dehydrogenase in BCS3-L1 making it entirely deficient in lactic acid production.

Abstract Dental caries is a chronic contagious disease caused by the interaction of oral microorganisms, diet and host factors over time. Streptococcus mutans is considered as the main bacteria involvs in dental decay, while the level of Lactobacillus spp.

is directly related to the presence or onset of caries. Commiphora myrrh is an ancient plant which extracts are used as antiseptic and anti.

Streptococcus mutans (S. mutans) has important virulence factors related to the etiology and pathogenesis of dental caries.

Through mechanism of adhesion to a solid surface, S. mutans is able to colonize the oral cavity and form dental biofilm, which is composed of a matrix of exopolysaccharides that affect the physical and biochemical structure of the : Bojanich María Alejandra, Orlietti Mariano Daniel.

Streptococcus mutans, a major pathogen of dental caries, is regarded as a causative agent of infective endocarditis (IE), which mainly occurs in patients with underlying heart r, it remains unknown whether severe dental caries that extend to pulp space represent a possible route of infection.

dental caries is high and more than 90% of caries is untreated. The level of caries is higher for the primary *Corresponding author: Email [email protected] q The Authors Streptococcus mutans and Streptococcus sorbrinus are important bacteria in the development of dental caries. Both these bacteria readily.

Unfortunately, many children are afflicted with dental caries at an early age, even those as young as 12 months of age. The purpose of this study is to determine the association between Early Childhood Caries (ECC), Streptococcus mutans and genetic sensitivity levels to the bitter taste of, PROP among the children below 71 months of age.

Streptococcus mutans is considered the principle causative organism in the initiation and progression of dental caries due to its acidogenicity, aciduricity, insoluble glucan production and other virulence factors, which have been extensively studied[6–8].

Salivary S. This study aimed to investigate effects of caries activity on composition of mutans streptococci in saliva-induced biofilms formed on bracket materials. Three bracket materials were used as specimens: ceramic, metal, and plastic.

After saliva was collected using a spitting method from caries-active (CA, decayed, missing, filled teeth (DMFT) score ≥ 10) and caries-free (CF, DMFT score = 0. dental caries than the quantity of S.

mutans and indicated that evaluation of the Ss/TS ratio was more useful than the total number of S. sobrinus. Key Words: Dental caries, Streptococcus sobrinus, Epidemiology, Public health Introduction Dental caries is a bacterial infection characterized by the. Dental caries is an infectious oral disease caused primarily by complex interactions of cariogenic oral flora (biofilm) with dietary carbohydrates on the tooth surface over time.

Streptococcus mutans and Streptococcus sobrinus (S. mutans and S. sobrinus) are the most prevalent cariogenic species within the oral biofilm and considered the main. The aim of this in vitro study was to evaluate the surface properties of moderately to severely fluorotic enamel and the adhesion of Streptococcus mutans and Streptococcus sanguinis to enamel, exploring the relationship between dental fluorosis and dental caries.

Streptococcus pneumoniae (a major cause of human pneumonia) and Streptococcus mutans and other so-called viridans streptococci (among the causes of dental caries) do not possess group antigens. Three types of hemolysis reaction (alpha, beta, gamma) are seen after growth of streptococci on sheep blood agar.

Abstract: Although dental caries is a global problem in modern times, no vaccines are available for preventing these diseases. Among the bacterial pathogens that cause dental caries, including Streptococcus mutans, S.

sobrinus, and Lactobacillus acidophilus, and Actinomyces viscosus, S. mutans is the most prominent and prevalent species. 7-Epiclusianone (7-epi), a novel naturally occurring compound isolated from Rheedia brasiliensis, effectively inhibits the synthesis of exopolymers and biofilm formation by Streptococcus the present study, the ability of 7-epi, alone or in combination with fluoride (F), to disrupt biofilm development and pathogenicity of S.

Streptococcus mutans and its correlation with dental caries have been carried out on children [3,10] and a few on adolescents [] while the data on adults are uncommon []. Saliva has been used to screen the oral load of Streptococcus mutans and.

Streptococcus mutans is a facultatively anaerobic, gram-positive coccus (round bacterium) commonly found in the human oral cavity and is a significant contributor to tooth decay. It is part of the "streptococci" (plural, non-italic lowercase), an informal general name for all species in the genus microbe was first described by James Kilian Clarke in Streptococcus mutans is a gram-positive facultative anaerobic bacterium that belongs to a group of mutans streptococci consisting of S.

sobrinus and several other species (Figure 4).The colony morphology of S. mutans is rough when grown on plates with mitis salivarius agar, a selective medium for mutans streptococci, whereas that of S.

sobrinus is smooth (Figure 5).“S. mutans was first described by James Kilian Clarke () after he isolated it from a carious lesion, but it was not until the ’s that real interest in the microbe was generated when researchers began studying dental caries” (Akhaven, ) was re-identified in infection of animal rodents.

All of Koch’s postulates were tested in animal models, but it was difficult.
