Caries Risk Test

Microorganisms, mutans streptococci and lactobacilli in particular, play a decisive role in the development of caries. They can harm both healthy as well as restored teeth. Consequently, it is very important to gather information about the existence of these microorganisms as early as possible and on a regular basis.

The CRT bacteria caries risk test facilitates the detection of mutans streptococci and lactobacilli in saliva.

CRT (Caries Risk Test)


Microorganisms – A key to caries

Various factors influence dental health. Important is the interaction between harmful and protective factors. Microorganisms, sugar, and unhealthy eating habits are detrimental to dental health, whereas saliva, oral hygiene, and the natural resistance of the teeth represent the protective counterweight. Microorganisms play a key role in the development and progression of caries. Usually, the various types of bacteria in the oral cavity are in equilibrium. The risk of developing disease increases if the number of certain bacteria, i.e. mutans streptococci or lactobacilli, substantially rises, while the protective factors cease to function optimally. Special properties render these bacteria highly cariogenic.
