Instructions for use KEY Laser III 1243

4 Operation

4.9 Modes

Three modes are available to the user:

▪ Standard therapy mode

▪ DETECT (detection mode)

▪ FEEDBACK (feedback mode)

Note

Foreign light sources can cause problems with the detection/feedback system by

illuminating the optical applicators. This is identified by a broad spread of MOMENT

values. These outside disturbances must be identified and eliminated.

Tools for finding plaque can generate an elevated fluorescence signal; teeth should

therefore be carefully cleaned beforehand.

Fluorinated toothpastes can change the fluorescence signal. The measurements

should hence be taken before using fluorinated toothpastes.

Seals, amalgam and composite fillings can also change the fluorescence signal.

Detection and feedback modes use the fluorescent radiation emitted by altered tooth

substance on exposure to a specific light wavelength. This radiation is detected and

evaluated.

When the following points are not taken into consideration, the detection and feed‐

back values can be misinterpreted:

▪ Soiling

▪ Composite fillings that are fluorescent

▪ Composite fillings with contaminated edges

▪ calculus/concretions

▪ Instances of higher values have been observed close to the pulp

▪ Food residue in the fissures

▪ Prophylaxis pastes

▪ remineralised caries

▪ discoloured teeth that are naturally highly fluorescent

▪ patients who have been exposed to radiation

The mode (DETECT or FEEDBACK) whose key appears bright with dark inscription

is activated.

To change to another mode, press the corresponding key.
