Dysbiosis as a determinant factor of systemic and oral pathology: importance of microbiome

Advances in genetic and epigenetic studies modified some concepts of health and disease that had been kept intact for decades. In this respect, in the last few years, microorganisms that have evolved with superior life forms for millions of years have taken an increased prominence. The genes of organisms and their microbiota constitute a microbiome that intervenes in health maintenance. The oral cavity is inhabited by a variety of microorganisms, their control aids in stabilising oral and systemic disease. The objective of this article is to update some concepts related to oral microbiome and its correlation with general and oral health. (C) 2017 Elsevier Espana, S.L.U. All rights reserved.
