Mouth infections are most commonly caused by an overgrowth of bacteria that normally populate the oral cavity. [1] In a healthy adult, billions of bacteria, viruses, and fungi reside within the oral cavity and represent more than 500 different species. They are collectively known as the oral microbiome.
Dental cavity, also known as tooth decay, [a] is the breakdown of teeth due to acids produced by bacteria. [6] The resulting cavities may be a number of different colors, from yellow to black. [ 1 ] Symptoms may include pain and difficulty eating.
The species has been implicated in periodontal disease, as well as various tooth cavities. [1] In other cases, A. naeslundii is associated with good oral health. It is one of the first bacteria to occupy the oral cavity and colonize the tooth's surface. It has also been isolated from women with bacterial vaginosis. [2]
It is a meticulously formed microbial community, that is organised to a particular structure and function. [12] Plaque is rich in species, given the fact that about 1000 different bacterial species have been recognised using modern techniques. [13] A clean tooth surface would immediately be colonised by salivary pellicles, which acts as an ...
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]
Tooth pathology is any condition of the teeth that can be congenital or acquired. Sometimes a congenital tooth disease is called a tooth abnormality.These are among the most common diseases in humans [1] The prevention, diagnosis, treatment and rehabilitation of these diseases are the base to the dentistry profession, in which are dentists and dental hygienists, and its sub-specialties, such ...
A. viscosus causes periodontal disease in animals and has been isolated from human dental calculus and root surface caries, as well as the oral cavity of hamsters and actinomycotic lesions in swine, cats, and dogs. [3] [4] Furthermore, it has been shown to cause endocarditis in humans. [5]
Early childhood caries (ECC) is a multifactorial disease, with risk factors including but not limited to, cariogenic bacteria, diet practices and socioeconomic factors. [6] Deciduous teeth begin to erupt at 6 months of age, once visible in the oral cavity they are susceptible to tooth decay or dental caries. [1]
