Oral Microbiology

Oral microbiology is the study of the microorganisms i.e. microbiota of the dental cavity and their interactions between the oral microorganisms or with the host. The environment of human mouth is suitable for the growth of characteristic microorganisms found there. It supplies a good source of water and nutrients, as well as a moderate temperature for growth. Normal micro flora of the mouth adheres to the teeth and gums to survive from mechanical flushing from the mouth to stomach where acid-sensitive microbes are demolished by hydrochloric acid (HCL). Anaerobic bacteria in the oral cavity include: 
Actinomyces, Arachnia, Bacteroides, Bifidobacterium, Eubacterium, Fusobacterium, Lactobacillus, Leptotrichia, Peptococcus, Peptostreptococcus, Propionibacterium, Selenomonas, Treponema, and Veillonella. Genera of fungi that include Candida, Cladosporium, Aspergillus, Fusarium, Glomus, Alternaria, Penicillium, and Cryptococcus are often found in the mouth. Among others, Bacteria assemble on both the hard and soft oral tissues in biofilms. Bacterial adhesion is mainly important for oral cavity.
