Modern dentistry faces the challenge of meeting the increased need of patients for health, functionality and aesthetics. In this light, it is becoming increasingly important to consider and actively use holistic aspects in diagnostics and therapy. Besides classic artisan dental medicine, biological dentistry also takes into account the basic principles of natural science in its complexity and interaction with regard to the human organism. Under the motto, “The Mouth as a Mirror for Health”, biological dental medicine takes a closer look at the basic principles of chemistry, physics and biochemistry and establishes a connection between the chronic systemic diseases and disorders of the oral cavity.
