The diseases which spread from one person to another. The diseases which are not transmitted from one person to another. They are caused by pathogens, e. They are caused by deficiency of nutrients, allergy, abnormal proliferation of cells etc.
Leeuwenhoek, a Dutch scientist, performed many experiments testing and observing bacteria. Biofilms are communities of bacteria, or micro-organismsattached to surfaces in the body. Oral biofilms are more commonly referred to as plaque. Biofilms form almost everywhere bacteria are.
In the mouth, they naturally form on any stationary surface, namely teeth, gums, and the tongue. Ecology and types[ edit ] The human mouth contains around to 1, different types of bacteria with various functions as part of the human flora and oral microbiology.
About to species may live in them at any given time. Streptococci make up a large part of oral bacteria. Streptococcus mutans make up a large majority of what affects our mouths. For example, some of these bacteria produce organic acids that kill the organisms that cause intestinal problems.
Bacteria are also needed to control the growth of fungus. These bacteria are transmitted to a human early in their childhood through their contact with their caretakers by kisses or food premastication. To grow and flourish in the mouth, biofilms go through four main stages of growth.
Then the bacteria, or micro-organisms, grow and replicate. Since bacteria can grow exponentially in short periods of time, it can quickly and easily create biofilms.
Third, the biofilm matures and accumulates more mass on the surface. Bacteria can continue to divide and grow by binary fission until nutrients begin to run out or their growth is inhibited. Bacteria can then reattach and start to grow and the cycle continues.
Bacteria and its growth are two of the principal components of oral ecology. Saliva keeps the ecosystem of the mouth in balance. It contains its own bacterial enzymes that are beneficial to our health. An example of these are lysozomes. These antibacterial agents in saliva kill bacteria in our mouths and protect from potentially dangerous diseases.
Some of the proteins provide nutrients for bacteria, while others cause bacteria to clump together so they are unable to stick to any surface and are washed away.
The main function of saliva is to flush out all of the micro-organisms that could potentially threaten our health. Many harmful micro-organisms, therefore, are unable to attach quick enough to a surface before they are caught in saliva and swallowed. Many diseases are related to oral bacteria.
Proper oral care and habits can protect against and reduce the effects of some harmful bacteria. Some examples of the milder diseases passed through saliva include herpes simple virus cold sores or canker soresflu virus, cold virusand various bacteria that cause periodontal disease inflammation or infection of gum tissuevenereal diseasesand candida albicans fungus.
It is a contagious viral disease in the herpes virus family. Diseases related to oral hygiene[ edit ] Other serious and possibly life-threatening diseases have been found to be connected to oral hygiene. Streptococcus mutans, a common oral bacteria discussed above, is a pathogen that causes pneumonia, sinusitis, otitis mediaand meningitis.
Brushing and flossing teeth regularly are the most basic ways to reduce these risks. These two fundamental hygiene tips help to get rid of bacteria that try to stick to surfaces in our mouth to form plaque oral biofilms.
The less you brush your teeth, the better chance that bacteria will form plaque and potentially cause serious oral and health issues. This is true because much of the bacteria in our mouths are nourished by simple sugars and carbohydrates.Times have changed.
The past 5 to 10 years have seen ballooning interest in possible links between mouth health and body health. "Physicians are taking a more holistic approach to their patients’ overall health," says Sally Cram, DDS, PC, consumer advisor for . A Healthy Mouth is a Gateway to a Healthy Body Studies are continuing to show a strong correlation between oral health and general health, so it should come as no surprise that a healthy mouth is important for more than just a pretty smile.
