Gram positive bacteria and their distributions according anatomical site in oral cavity and effects on oral health

A healthy adult's body is thought to contain ten times more microorganisms than human cells. These include a wide variety of bacteria, fungi, viruses, and archaea. The Human Microbiome Project (HMP), recently launched by the National Institutes of Health, emphasizes how critical it is to characterize human microbiota in order to comprehend health and illness. An imbalance in the usual microbiota or alterations in colonization sites may be the cause of the illness. A wide variety of infectious disorders are frequently intimately associated with oral bacteria, as the mouth is home to a complex, diverse, and prolific microbial population. Because they negatively impact people individually, in groups, and throughout society, oral disorders are a significant public health problem.
