The subject is focused on medical chemistry for dentist. Inorganic and organic chemistry concentrated on nutrition, toxicology and especially on stomatologic materials (alloys, amalgams, dental cements, silicates and synthetic materials).
The students should manage the basic work in the chemical laboratory, the inorganic, organic and biochemical analysis and acqaint with the principles of use of dental materials.
