Oral and Systemic Diseases: Critical Relationships Between Human Health, Tooth Decay, Periodontal Diseases and Multidisciplinary Care.

Oral health has long been considered to be on the bangs of systemic health. And yet, as recently as 2024, the World Health Organization stated once again that oral diseases rank first in the world in terms of prevalence. This review aims to highlight data from the literature demonstrating the relationships between oral and systemic diseases. The tissues of the oral cavity, teeth, their bony bases and supporting tissues can each suffer from pathologies, often infectious, whose consequences can be found at local, regional and systemic levels. These disorders affect children and adults of all ages. Their management is a public health issue that involves all medical practitioners.
