Periodontitis is defined as the microbial infection of the periodontal membrane leading to pyorrhea, and resulting in the teeth falling out if left untreated. It is the inflammation of the periodontium. Periodontitis can occur from the penetration of the periodontal membrane by pathogenic bacteria or the activation of resident oral bacteria in the mouth. Prior
Gingivitis is simply defined as the inflammation of the gum (gingivae) caused by microbial activity. It is the redness and swelling of the gingival tissues or gum as a result of bacterial infection. Gingivitis is mediated by oral bacteria including Fusobacterium species, Bacteroides, Entamoeba gingivalis, Prevotella species, Bacillus intermedius, Capnocytophaga species, Veillonella speciesand Actinomyces species.
Dental plaque is defined as the tenacious microbial deposit that forms on the hard tissue of the tooth surface. It comprises of living, dead and dying bacteria and their metabolic products as well as the components from the host saliva. Plaque formation also occur on restorations and other prosthetic appliances fixed in individuals who may
Dental caries is simply defined as the decaying of the teeth. It can also be called dental decay. Dental caries or dental decay is a gradual disintegration of the teeth beginning from the tooth surface and progressing inwards. And it is usually initiated by microbial activity going on around the tooth surface. Dental caries include
The microbiota of dental diseases describes the microorganisms (inclusive of normal flora of the oral cavity and other pathogenic microorganisms) that cause several pathological conditions in the oral cavity – especially as it pertains to the teeth and its associated vessels or structures. The diseases of the teeth include dental plaque, periodontitis, dental caries or

The first investigation into the world of oral bacteria was first made by the father of microbiology Anthony von Leeuwenhoek (1632-1723) – who was the first microbiologist to observe and describe microorganisms accurately. Leeuwenhoek observed his mouth washings under his amateur microscope and discovered small living creatures which he called animalcules. Leeuwenhoek opined in his
