INTRODUCTION
The CariScreen system is intended to provide a fast, easy
screening test for dental caries via the use of an ATP
bioluminescence test.
The CariScreen system consists of two elements: the CariScreen
hand-held Caries Susceptibility Testing Meter and the disposable
CariScreen Caries Susceptibility Testing Swab.
This Operator’s Manual provides a detailed description of how to
use the CariScreen Meter, and how to handle maintenance and
troubleshooting.
For full details on the CariScreen Swab device, please refer to the
CariScreen Swab kit insert.
1
.1 PRINCIPLE OF OPERATION
The CariScreen Swab device uses bioluminescent chemistry
technology to convert an invisible concentration of ATP (present in
the swabbed sample) into a visible light output.
The low-level light output is measured by the CariScreen Meter to
produce both a quantitative and qualitative result.
The quantitative result is a number in the range 0 to 9999,
expressed in terms of Relative Light Units – RLUs.
Although Relative Light Units are not a tangible unit of light
measurement (such as lux), they do provide a real measure of the
amount of light output by the ATP bioluminescent test.
In this application, 1 RLU is roughly equivalent to 1 fmol of ATP.
