DETERMINATION OF CYCLIC FATIGUE OF A NICKEL-TITANIUM COXO SC PRO FILE USING A SIMULATION ENDODONTIC UNIT.

The use of nickel-titanium instruments during endodontic treatment ensures high-quality treatment of root canals. However, during instrumentation in the curved root canals of nickel-titanium instruments experience cyclic loading, which leads to their breakage. The splinter of the tool in the root canal makes it difficult for high-quality processing and obturation of the root canal, which is a very urgent problem.

[Large intestine microflora of patients with various clinical forms of salmonellosis].

The study of the asporogenic and facultative microflora in the contents of the large intestine in salmonellosis patients has revealed the presence of dysbacteriosis manifested, irrespective of the serovar of the isolated infective agent, by a decrease in asporogenic microflora and an increase in E. coli and staphylococci. Dysbacteriosis develops irrespective of the clinical form of the disease, but it is more pronounced if the disease takes a dysentery-like course.
