UNASSIGNED: This
review shows the history of inventions of devices, hygiene products, and methods of dissolution and removal of
pus, sulfur plugs, blood crusts, and plaque.
UNASSIGNED: The search for inventions was carried out in the databases, such as Google Patent, Google Scholar, Scopus, and PubMed. The key words used in this search were as follows: toothbrushes, toothpicks, toothpastes, plaque, cleaning products for teeth and dentures, teeth whiteners and dentures, bleach bruises and blood stains, pus, sulfur plugs, and
pus solvents. A total of 24 inventions were evaluated for
review.
UNASSIGNED: In recent years, hygiene products that quickly dissolve and bleach
pus, sulfur plugs, blood stains, and plaque because of alkaline saponification of protein-lipid complexes and cold boiling inside the biological masses have been invented. Such an action has a heated above 37°C supersaturated sodium bicarbonate solutions containing hydrogen peroxide in moderate concentrations and gaseous oxygen under excessive pressure. Cold boiling inside the dense biological masses occurs under the action of catalase and/or due to the normalization of internal pressure in the solution.
UNASSIGNED: Alkalinity, hyperthermia, and hyperoxygenation of solutions with high internal pressure optimize whitening of teeth and dentures because of alkaline saponification and cold boiling.
