METHOD PERFORMANCE TESTING STRUCTURAL hemolytic dental material

摘要

FIELD: medicine.;SUBSTANCE: invention belongs to medicine and can be used in dentistry for constructive prosthetic materials choice. Method for hemolytic testing of constructive dental material is offered. Blood agar with human erythrocytes is poured into 2 Petri dishes. One is inoculated with pure culture of hemolitically active microorganism, typical for microbial population of oral cavity. On the nutritive medium of both dishes are placed patterns of constructive dental materials in form of plates. Dishes are incubated. After incubation dishes are examined. Presence or absence of dental constructive material hemolytic properties is found out by presence of hemolytic zone of erythrocytes close to pattern. Hemolytic zone width correlates with hemolytic activity. If hemolytic zone appears only in blood agar with microbial culture, then dental constructive material hemolytic properties are actual only in the presence of microorganisms in question.;EFFECT: method enlarges performance capability due to detection of dental construction material hemolytic properties in the presence of human oral cavity microbial population with hemolytic activity.;2 tbl
