How does Streptococcus produce dental caries?

Streptococcus mutans, which causes dental caries, splits the sucrose in food and uses one of the sugars to build its capsule, which sticks tightly to the tooth. The bacteria that are trapped in the capsule use the other sugar to fuel their metabolism and produce…

What bacteria initiates caries?

The mouth contains a wide variety of oral bacteria, but only a few specific species of bacteria are believed to cause dental caries: Streptococcus mutans and Lactobacillus species among them.

Why is extracellular polysaccharide significant to S mutans?

Extracellular polysaccharides (PS) synthesized by oral bacteria constitute one of their major virulence factors. The PS, synthesized from sucrose, facilitate adhesion and colonization by bacteria to tooth surfaces. mutans was measured by [3H]-thymidine incorporation into the bacteria.

How does the glucosyl transferase play a critical role in pathogenesis of dental caries?

Bacteria-derived glucosyltransferases (Gtf) (EC 2.4. 1.5), through synthesizing glucan polymers from sucrose and starch hydrolysates, play an essential role in the etiology and pathogenesis of caries. There was a strong correlation between mutans streptococci populations in saliva and caries activity.

What kills Streptococcus mutans?

First, A12 makes hydrogen peroxide, a chemical weapon that kills S. mutans. Yes, hydrogen peroxide- the same stuff we use to disinfect wounds! Hydrogen peroxide is highly reactive and can kill most germs.

What color is Streptococcus mutans?

Streptococcus mutans can be identified by a chalky white spot on the surface of the tooth indicating an area of demineralization of enamel, which is commonly referred to as a carious lesion.

Which vitamin is necessary for tooth formation?

Vitamin D. Vitamin D is doubly important because not only does it boost mineral density, it also helps absorb, carry, and deposit calcium in the bones that support your teeth.

Who discovered Streptococcus mutans?

S. mutans was first described by James Kilian Clarke (1886-1950) after he isolated it from a carious lesion, but it was not until 1960s that real interest in this microbe was generated when researchers began studying dental caries (8). S.

Does Listerine reverse cavities?

Did you know, if found early enough, you can sometimes reverse certain tooth decay by brushing twice a day with a fluoride toothpaste, and rinsing with a fluoride-containing mouthwash such as LISTERINE ULTRACLEAN® ENAMEL PROTECTION or LISTERINE TOTAL CARE®? This repeated practice can help re-mineralize tooth enamel.

Does Listerine fight cavities?

Mouthwash freshens bad breath, can help reduce plaque and gingivitis, as well as fight tooth decay and prevent cavities. Mouthwash can really help improve your oral health. Mouthwashes containing fluoride can even help remineralize your teeth.
