The handpiece with the Proxi interchangeable
head creates a black and white image for detect-
ing caries in the approximal region.
The optical element is placed on the row of teeth.
An image is created by actuating the trigger but-
ton. The spacer facilitates the placement of the
optical element on the row of teeth. In addition,
the spacer screens off the image area and min-
imises the penetration of external light.
Two powerful infra-red LEDs are installed in the
optical system. The infra-red light illuminates the
tooth and is reflected with varying intensity
depending on the translucence (light transmis-
sion) of the dental structures. The reflected light
is recorded by the optical element and is anal-
ysed as a black and white image in the VistaSoft
imaging software.
Evaluation
The black and white image shows structures with
varying translucency as different levels of bright-
ness. The lower the translucency, the higher the
reflection of the infra-red light and the brighter the
structure. It is possible to make out to following
structures:
– Healthy enamel appears very dark, high
translucency
– Approximal caries appears bright, low translu-
cency
– Dentine appears bright, low translucency
– Several restorations appears bright, no translu-
cency
Fig. 4: Case example 1 – Lesions in the mesial
area are visible as a wide bright strip up to the
enamel/dentine boundary.
Fig. 5: Case example 2 – Enamel lesions can be
seen as wedge-shaped structures within the
dark translucent tooth enamel. The lesions
reach to the inner half of the enamel.
The system cannot distinguish between struc-
tures with the same amount of translucency.
Thus it is not suitable for the diagnosis of:
– Secondary caries under restorations
– Dentine caries
– Central occlusal caries
