  2. Oral microbiology - Wikipedia

    en.wikipedia.org/wiki/Oral_microbiology

    Oral microbiology is the study of the microorganisms (microbiota) of the oral cavity and their interactions between oral microorganisms or with the host. [1] The environment present in the human mouth is suited to the growth of characteristic microorganisms found there. It provides a source of water and nutrients, as well as a moderate ...

  3. Oral ecology - Wikipedia

    en.wikipedia.org/wiki/Oral_ecology

    Bacteria were first detected under the microscope of Dutch scientist Anton van Leeuwenhoek in the late 17th century from his own healthy human oral sample. [1] After using this technology on a healthy sample, Leeuwenhoek applied his tool to the decayed tooth matter of his wife, where he noted that the organisms present were highly similar to those found in cheese.

    Dental calculus. Since the 1980s, it has been well known that archeological dental calculus preserves cellular structures and oral bacteria, but a new discovery in the last decade has revealed that dental calculus is a long-term reservoir of DNA and proteins. [1]

  5. Streptococcus mutans - Wikipedia

    en.wikipedia.org/wiki/Streptococcus_mutans

    Different areas of the oral cavity present different ecological niches, and each species has specific properties for colonizing different oral sites. S. mutans is most prevalent on the pits and fissures, constituting 39% of the total streptococci in the oral cavity. Fewer S. mutans bacteria are found on the buccal surface (2–9%). [7]

    The oral microbiota consists of all the microorganisms that exist in the mouth. It is the second largest of the human body and made of various bacteria, viruses, fungi and protozoa. [14] These organisms play an important role in oral and overall health. Anthony Van Leeuwenhoek was the first to view these organisms using a microscope he created ...

    Saccharibacteria, formerly known as TM7, [1] is a major bacterial lineage. It was discovered through 16S rRNA sequencing . [2]TM7x from the human oral cavity was cultivated and revealed that TM7x is an extremely small coccus (200-300 nm) and has a distinctive lifestyle not previously observed in human-associated microbes. [3]

    en.wikipedia.org/wiki/Dental_plaque

    These bacteria, as well as leukocytes, neutrophils, macrophages, and lymphocytes, are part of the normal oral cavity and contribute to the individual's health. [1] Approximately 80–90% of the weight of plaque is water. While 70% of the dry weight is bacteria, the remaining 30% consists of polysaccharides and glycoproteins. [7]
