Microbiome composition of human dental calculus correlates with dietary intake.

Within and beyond our bodies, compromised bacteria, archaea, viruses, and eukaryotes make up our microbiota. Our native microbiota can interact with biology and culture to affect our health and disease, as well as our behavior and quality of life. Microorganisms can colonize a variety of places on and inside the human body, adapting to the unique characteristics of each niche. The oral microbiota, which is vital to the human microbiome and health, interacts with one another and with the host immune system. Microbe-host imbalances can lead to oral disorders, as well as chronic diseases. The microorganisms that live in human digestive tracts are known as gut microbiota which might be regarded as a virtual organ of the body, with several functions that play a critical part in health maintenance. Dietary factors can have an impact on their composition and health. We have done DNA extraction from 42 samples of varying ages and gender to demonstrate the impact of nutrition on the human oral microbiota according to their preferences to use different diet mainly the Mediterranean diet and divided the results into four clusters, each representing a different microbial genus. The systematic review's major finding was an increase in Streptococcus in Cluster 1 as a result of a fiber and vegetable diet, also the result demonstrated the high abundance of the Porphyromonas gingivalis and Tanerella as one of the main periodontal diseases in cluster number 4 that were associated with the animal based products such as meat and dairy products.
