1.2 ESD protective measures Operating Instructions SIDEXIS – Intraoral
1.2 ESD protective measures
ESD is the abbreviation for ElectroStatic Discharge.
Connector pins or sockets bearing ESD warning labels
must not be contacted or interconnected without ESD
protective measures.
ESD protective measures include:
• Procedures for preventing electrostatic charges
(e.g. via air conditioning, air moistening, conductive
floor coverings and nonsynthetic clothing)
• Discharging the electrostatic charges of your own
body on the frame of the U
wire or large metallic objects
• Connecting yourself to ground using a wrist band.
We therefore recommend that all persons working with
this system be instructed on the significance of this
warning label. Furthermore, they also should receive
training in the physics of electrostatic discharges which
can occur in the practice and the destruction of electronic components which may result if such components
are contacted by electrostatically charged USERS.
The content of this training is specified in Chapter 1.3.
NIT, the protective ground
1.3 Concerning the physics of electrostatic charges
ESD is the abbreviation for ElectroStatic Discharge.
Electrostatic discharge must be preceded by electrostatic charging.
Static electric charges generally occur whenever two
bodies are rubbed against each other, e.g. when walking
(shoe soles against the floor) or driving a car (tires
against the street pavement). The amount of the charge
depends on several factors:
I.e. the charge is higher with a low air humidity than with
a high air humidity and higher with synthetic materials
than with natural materials (clothing, floor coverings).
The following rule of thumb can be applied to gain an
overview of the compensating voltages resulting from an
electrostatic discharge.
An electrostatic discharge is:
• perceptible at 3000V or higher
• audible at 5000V or higher (cracking, crackling)
• visible at 10,000V or higher (arc-over)
The compensating currents resulting from these discharges have a magnitude of 10 amperes. They are not
hazardous for humans because they last for only several
nanoseconds.

Sirona Dental Systems GmbH 1 Warning and safety information
Operating Instructions SIDEXIS – Intraoral 1.3 Concerning the physics of electrostatic charges
Voltage differences exceeding 30,000 volts per centimenter may lead to a charge compensation (electrostatic discharge, lightning, arc-over).
Integrated circuits (logical circuits and microprocessors)
are used in order to enable a wide variety of functions in
a dental/X-ray/CEREC system. The circuits must be
miniaturized to a very high degree in order to include as
many functions as possible on these chips. This leads to
layer thicknesses with a magnitude of several ten thousandths of a millimeter.
It is obvious that integrated circuits which are connected
to plugs leading outside of the unit via cables are sensitive to electrostatic discharge. Even voltages which are
imperceptible to the user can cause breakdown of the
layers, thus leading to a discharge current which melts
the chip in the affected areas. Damage to individual integrated circuits may cause malfunction or failure of the
system.
To prevent this from happening, the ESD warning label
next to the plug warns of this hazard.

The sensors illustrated are representative of all Sirona
X-ray sensors.
The X-ray sensor is placed according to the known principles of the half-angle or right-angle technique.
Half-angle technique without collimator!
According to the size of the tooth or position of the area
to be exposed, place the X-ray sensor vertically or horizontally into the mouth of the patient. The patient can fix
the sensor by independently holding it as usual.
Right-angle technique
For reasons of dose reduction, for the right-angle technique we recommend using the holder system supplied.
Use of the different sensor holders with guide rods and
sight rings with the right-angle technique is described in
separate operating instructions from Rinn
For reasons of clarity, no hygiene protection is shown in

8.2 Switching the unit on Operating Instructions SIDEXIS – Intraoral
Following buildup of the connection the message "Place
the sensor" is displayed briefly.
After a few seconds the system is ready for the exposure:
The message "Waiting for exposure ..." appears in the
dialog box.
In addition the green indicator in the window starts to
flash.
Readiness for exposure is now signalled on the acquisition unit as well.
The yellow signal LED (4) or (5) assigned to the corresponding sensor lights up in addition to the green signal
LED (3).
Assemble the holder combination for right-angle technique intended for the relevant type of exposure according to the Operating Instructions, fit the required hygiene
protection and place it with the X-ray tube assembly and
the sensor on the patient.
The exposure can now be made with the X-ray tube
assembly.
For exposure times refer to Chapter 11 "Exposure values".
If no radiation is released, the unit status changes after
15 minutes from ready for exposure back to ready for
operation.
If no readiness dialog appears and the display in the dialog does not flash or the signal LEDs on the acquisition
unit do not light up, then no X-ray exposures may be taken on the patient until the cause of this problem is rectified.
After the exposure the LED assigned to the sensor starts
to flash alternatingly with the operating indicator LED (3)
and the data are transferred.
The unit may not be switched off until the data transfer is
completed. This status is shown by the operating indicator LED (3) lighting up continuously.

CAUTION
Operating Instructions SIDEXIS – Intraoral 11.1 Exposure control
11 Exposure control,
adapting exposure data
11.1 Exposure control
The radiation dose acquired by the X-ray sensor as a
result of the exposure data selected affects the image
quality.
The X-ray sensor accepts a wide exposure tolerance.
Thanks to automated image preprocessing, the exposures are displayed with optimized brightness and optimized contrast.
Nevertheless a noisy, unsharp image can result if the
dose is too low. – This is in contrast to an excessive
dose, which results in overmodulation of the sensor and
can thus cause dark fields in the image.
11.2 Adapting exposure data
Image artifacts due to excessively low dose can be compressed in part through subsequent image postprocessing. Image artifacts due to overmodulation of the sensor,
on the other hand, cannot be compensated for!
HELIODENT DS
You can switch over from conventional to digital exposure technique by briefly pressing the D key. The
reduced
exposure time for this is displayed. The Digital indicator
must light up.
For the HELIODENT DS exposure values see page 24.

11.2 Adapting exposure data Operating Instructions SIDEXIS – Intraoral
Changing the basic value:
The basic value can be adapted as follows in the event
of different exposure conditions:
1. Set the large patient symbol to the middle range (upper jaw premolar/lower jaw molar) of the object selection switch (1).
2. Press the D key (approx. 4 sec.), until the ready for
operation LED and Digital flash.
Let go of the D key.
3. The basic value can be
increased + step by step
or decreased – by turning the
object selection switch.
4. Press the D key to save the value.
5. Set the object selection switch (5) back to the start-
ing position. The basic value is displayed 3 steps
higher.
If you do not want to save the value, do not press the D
key.
You must then switch the unit OFF and then ON again.
Adjacent example:
Changing the basic value in digital radiography from 8"
cone to 12" cone (3 steps higher).

for Sirona Full Size / Universal X-ray sensors Only a few exposure values are sufficient for the highly
sensitive Sirona Full Size and Universal X-ray sensors.
The exposure values for X-ray sensors stated in the relevant documentation of the different Sirona intraoral
X-ray units therefore do not apply for the Sirona Full
Size and Universal X-ray sensors.
For other X-ray sensors please use the exposure times
from their operating instructions.
