Is dental plaque visible?
Plaque is the major cause of tooth decay and gum disease (gingivitis). It is hard to see with the naked eye because it is whitish colored, like teeth.
How many bacteria are in dental plaque?
Dental plaque is considered a biofilm adhered to the tooth surface. It is a meticulously formed microbial community, that is organised to a particular structure and function. Plaque is rich in species, given the fact that about 1000 different bacterial species have been recognised using modern techniques.
What is the structure of dental plaque?
Dental plaque is now recognized as a polymicrobial biofilm, defined as a community of microbial cells embedded in an extracellular matrix, that grows on an interface between two phases of matter, for example, the solid tooth surface and liquid saliva or GCF [55].
What does bad plaque on teeth look like?
When plaque isn’t removed from your teeth, it can harden into tartar. In the early stages, tartar is usually a yellow color, but if left untreated even longer, it can result in brown, green, or black tartar.

What bacteria is in dental plaque?

Although many bacterial subspecies have been shown to be associated with caries, Streptococcus mutans is still believed to be the most important bacterium in the initiation and progress of this disease in combination with lactobacilli.
Is plaque a calculus?
Calculus, also known as tartar, is a hardened plaque. When plaque isn’t effectively removed during your oral hygiene routine, minerals from your saliva combine with the plaque to develop tartar.

What microorganisms are present in dental plaque?
What’s the difference between plaque and calculus?
Calculus, also known as tartar, is a hardened plaque. When plaque isn’t effectively removed during your oral hygiene routine, minerals from your saliva combine with the plaque to develop tartar. Unlike plaque, tartar cannot be brushed away.
What is calculus in dentistry?
In dentistry, calculus or tartar is a form of hardened dental plaque. It is caused by precipitation of minerals from saliva and gingival crevicular fluid (GCF) in plaque on the teeth.
How do things appear under a microscope?
Using the microscope,examine the specimen by eye and select the area of interest and magnification required.
What happens to the image under a microscope?
What happens to an image under a microscope? The image is always upside down, so what you see through a microscope shows up as the opposite of what you are doing. When you move an object to the right, it appears to move to the left, and when you move it up, its image moves down. The book also explains how to use microscopes.
How does the letter P appear under a microscope?
Under the microscope the E is upside down and backwards compared to the letter E on the slide. If the E is right side up and forward, under the microscope it is going to be upside down and backwards. Explain why a specimen that you wish to view with a compound light microscope must be very thin. One may also ask, what do you see under a
What does an egg look like under a microscope?
Under a microscope, they are yellow in color and appear to be the shape of a grain of rice. In optimal temperatures, fruit fly eggs hatch into larvae within 30 hours. These larvae ultimately mature into adults that feed, breed and lay their own generation of eggs. The life cycle of some fruit fly species is less than one week.
