[Effects of inorganic and organic fluorides combined with molybdenum and chlorohexidine upon processes of metabolism, fluoride content, and cariosity of the teeth of Wistar rats (author's transl)]. / Der Einfluss anorganischer und organischer Fluoride in Kombination mit Molybdän und Chlorhexidin auf Stoffwechselprozesse, Fluoridgehalt und Kariesbefall der Zähne von Wistarratten.

A study has been made to determine the inhibitory action upon the progress of dental caries of two trace elements (fluorine and molybdenum) combined with chlorohexidine with the goal of increasing the efficiency of fluoride treatment. However, the results obtained show that the chosen combination of trace elements did not lead to a substantial increase in cariostatic action. Combined use of fluorides and chlorohexidine was seen to exert an inhibitory action on the progress of dental caries.

[Fluoride contents of rat molars following the administration of amine-fluoride-containing caries preventives (author's transl)]. / Der Fluoridgehalt von Rattenmolaren nach der Applikation aminfluoridhaltiger Kariespräventiva.

Experiments on fifty Wistar rats were conducted with the object of studying the incorporation of fluoride into the enamel of molars subsequent to the administration of amine-fluoride-containing caries preventives. - Use of two toothpastes with low fluoride contents of 0.125% and 0.18% F, respectively, and two higher-fluoride (1% F) solutions resulted in a marked increase in the concentration of fluoride in the superficial layers of dental enamel.

[Calcium and phosphorus content and the 45Ca incorporation into the bones and teeth of rats after a 22-day orbital space flight on board the "Cosmos-605" satellite ship]. / Soderzhanie kal'tsiia, fosfora i vkliuchenie 45Ca v kostiakh i zubakh krys posle 22-sutochnogo kosmicheskogo orbital'nogo poleta na korable-sputnike "Kosmos-605"

Examinations of 37 rats flow for 22 days onboard the biosatellite Cosmos-605 revealed no changes in the mineralization coefficient or the Ca and P content in humerus and teeth of the animals on the 2nd and 26th postflight days. Radioisotope studies showed changes in the specific activity of Ca45 incorporation in humerus and incisors. In flight rats the parameter decreased by 37-44%, in synchroneous animals it increased by 102% in bones and by 20% in incisors as compared with the vivarium controls on the 2nd postflight day. The specific activity of Ca45 incorporation was 92.7% in humerus and 44.2% in incisors of flight rats and 72.9% in humerus and 94.7% in incisors of synchroneous rats as compared with the vivarium controls on the 26th postflight day.
