It is well known that plaque is the main cause of caries and parodontopathies, which puts the role of toothpastes as an important means of prevention of odontopathies to the foreground. Toothpastes can be more or less oriented towards having a particular effect, such as cleaning, anticaries effect, antimicrobial effect or inhibition of the formation of tartar. Toothpastes contain substances which promote dental health, such as abrasives (silicium dioxide, brushite, calcite, calcite and aragonite, gibbsite etc.), active components (fluorides, triclosan, metal ions, sanguinarine and surface-active substances), substances which motivate the use of toothpaste (sweetening agents, aromatic oil, colours) and components which are necessary for technical reasons, such as moisturizing agents, binders and opacifiers.
