Streptococcus mutans

Normal flora is the colonisation of human tissues by a diverse mixture of microorganisms. This colonisation begins at birth with pioneer species, depending on physiochemical factors. The normal flora inhibits the skin, oral cavity, upper respiratory tract, gastrointestinal tract, urogenital and conjunctival membranes. They are commensal bacteria; getting shelter and nourishment from the host without causing harm (Gould, 2012). To a healthy individual, most normal flora is harmless, however some…

acids/neuraminic acid or from non-sugar subunits such as pyruvyl, acetyl and formyl group.Capsules are either synthesized at the level of cell membrane or extracellularly as done by Streptococcus mutans using extracellular enzyme glucosyltransferase in the oral cavity. Individuals infected with capsulated bacteria like Streptococcus pneumonia, Klebsiella pneumonia, Neisseria meningitides, Haemophilus influenza, Bacillus anthracis, Yersinia pestis and others show anti-capsular antibodies in their…

Oral Hygiene Aids AbdulJabar Ali Almani 17 oct, 2016 M011442005 Alwaleed2016@yahoo.com Oral hygiene is a tool used to clean teeth and mouth from dental plaque (material alba) to get excellent hygiene.

In addition, visit dental clinics twice a year There are many types of oral hygiene aids for home care Dental floss Dental floss is the…

Dentistry is ever-changing, ever-advancing. Current dentistry practices halting and possibly reversing dental caries during its early stages of lesion development, rather than aggressively removing the early signs of dental caries by utilization of the drill. As progressive research educates dental professionals about different methods to interrupt demineralization of tooth structure, they are able to implement the use of certain dental products to restore and save natural teeth. MI Paste is a…

Dental Caries: The big culprit Dental caries is a dental terminology which can be otherwise called tooth decay. The tooth is the hardest structure is our human body and is made up of organic and inorganic contents It is approximately 45% inorganic material (mainly hydroxyapatite), 33% organic material (mainly collagen) and 22% water. Dental caries is a complex procedure that involves the combined action of bacterial toxins in an acidic environment that causes loss from the tooth structure. The…

In streptococcus mutans, p.gingivalis and fusobacterium nucleatum, proteome analysis is used to understand the molecular mechanism of invasion, survival and pathogenesis. F.alocis ATCC 35896 and D-62D strain have variation in their protein profile. F.alocis genome…

Bacterial identification is crucial to the healthcare setting in that it helps prevent or reduce disease. Multiple tests were conducted in attempt to identify the unknown microorganism that was swabbed from a cheek, and their materials, methods and results were described. The goal of the unknown lab experiment was achieved by identifying the genus and possible species through interpretation of the results found. Microbiology is the study of microscopic organisms. These organisms are virtually…

Can cavitation bubbles reduce the number of non-pathogenic E. coli on an ice cream scoop and the amount sloughed off into the water around the scoop? The results supported the alternate hypothesis which stated that both the scoop and the water, when subjected to cavitation bubbles, would show a significant reduction or change of E. coli bacteria. All statistical analysis was completed using the results from a Tukey-Kramer test. Overall, the statistical alternate hypothesis (μ≠μ) was supported…

sweetened with a substance called xylitol, sorbitol, and maltitol has been shown to actually reduce cavities and not cause tooth decay. The reason for this is because the material in this sugar free gum does not include the harsh substance of streptococcus mutans, which are bacteria that break down tooth enamel. This is because the food and sucrose take an affect on the teeth causing demineralization, but when added with calcium lactate it reduces this. Many times this calcium lactate is placed…
