[A light-hardened polymeric material for metal-plastic whole-cast fixed dentures].

Self-hardening material for metal plastic permanent dentures, has been developed by the Central Research Institute of Dentistry for the first time in Russia. Its physicomechanical properties are described and the results of toxicological trials are presented. The new material is superior in wear resistance to foreign analogs Kulzer Dentacolor and ESPE Visio-Gem. Toxicological studies demonstrated the biological inertness of the material during long contact with the internal media of human organism and the absence of toxic, sensitizing, and mutagenic action.

[The results of sanitary chemical and toxicological research on the tableted copper amalgam TMAS-01 for pedodontics].

Several modifications of copper amalgams were examined. The findings evidence that of the amalgam constituents only copper passes into saliva, nutrient media, and animal body tissues and accumulates there. The findings of sanitary chemical and toxicologic studies helped select a hygienically optimal copper amalgam sample exerting no detrimental effects on the body.

[The results of sanitary chemical research into denture base materials coated with components from essential-oil plants].

Examinations of the basic material for removable dentures, coated with rose, lavender, sage wax evidence that such coating essentially reduces residual methylmetacrylate migration and its side effect on the denture bed tissues, and improves the hygienic characteristics of dentures. Modification of the basic material by introducing Sklariol into the polymer considerably reduces the residual monomer migration. These results recommend coating of essential-oil plant wax for the prevention of denture bed tissue inflammations.

[Assessment of the biological properties of composite filling materials: determination of indices of their hemolytic activity and cytotoxicity].

Rapid methods for determining the hemolytic activity in 10% suspension of human red cells and the cytotoxicity in human embryo fibroblast and HeLa cell cultures were used to assess the biological characteristics of some experimental composite filling materials and their foreign analogs. The results permit assessing the impact on the biological characteristics of individual components, of the entire composition, of the purity of the initial ingredients and their polymerization ability, this being valuable for the development of materials with the optimal characteristics.

[Operational tests of "MOST", a new membrane oxygenator].

Functional and service characteristics of a Soviet membrane oxygenator are determined and compared with analogous foreign models. Results of hygienic examinations including medico-chemical and toxicological trials made it possible to evaluate oxygenator effects on a living organism.
