CRT bacteria

Test for determining mutans streptococci and lactobacilli counts in saliva and plaque

High counts of mutans streptococci and/or lactobacilli indicate a high caries risk status. If protective factors cannot take effect, carious lesions will develop. CRT bacteria provides you with fundamental information before any changes in the tooth structure can be detected. As a result, you have the possibility of introducing adequate counter measures at an early stage. The proven biological test CRT bacteria allows you to clearly identify and semi-quantitatively determine cariogenic bacteria.
