All objects which get into the oral cavity of a patient have to be pre-treated to avoid any infection
with any disease.
All objects which directly or indirectly get in touch with the mouth of the patient are regarded as
contaminated. Contaminated objects MUST NOT get in contact with other patients without any
disinfection/sterilization.
Direct unprotected contact with saliva or blood has to be avoided.
For your own safety you MUST, wear suitable protective equipment during the treatment in
accordance with country-specific occupational safety and health regulations, E.g. gloves, goggles
and face mask.
It is extremely important that any patient treatments planned in advance, thus all necessary
objects are available at the beginning of the treatment to save time and reduce the risk of cross
contamination.
To avoid cross contamination clean and dirty instruments must be kept separately.
All objects, which are directly or indirectly in contact with the patient, must be either professionally
disposed of following treatment or they need to be processed for cross infection control

For correct storage of the product please note the storage conditions (see section 5)
The device either has to be stored or transported in outer packaging (original cardboard box) or in
transport packaging (with cover).
For a stackability of several devices additional precautions have to be made.
Before t the DENTALONE, also when relocating from one room into another,
the fresh water tank (4) and the waste water collection tank (7) have to be emptied!
Spilled water can damage the electronic components of the DENTALONE.
The footswitch can be stowed in the space next to the waste water tank.
Before a bigger transport (from location to location) it is recommended to additionally carry out the
following measures:
 Cleaning, disinfection and sterilization as required (see section 9)
 Pull out the plug of the footswitch from the connector socket
 Bring console in transport position and lock
 Place foam insert on the console to protect the instruments and fold down instrument holder
 Stow instrument hoses and accessories in the device and fasten with webbing
 Make sure instruction for use manual is always kept with the DENTALONE
Attention! Before transport at minus temperatures the device has to be completely emptied from
water, which means in addition to the water tank also all internal water ways, until no spray mist escapes
at the hand pieces anymore, as otherwise frost damage may occur.
The same also applies to waste container and suction hose.
All internal waterways MUST be drained completely before any period of disuse, to prevent the formation
and development of germs.
In a final step the cover has to be pushed over the device and locked at 3 points (see fig. 1).

8.2 Preparation / initial operation
First of all the DENTALONE has to be connected to a suitable power supply using the power cord
provided (9) at the power inlet (1).
Please correspondingly consider the regulations for medically used rooms in accordance with DIN VDE
0107.
The instrument tubings and suction hoses have to be taken from the lower storage space and to be
structured in such a way that the loops are not entwined with each other.
Now the power switch (1) at the left side of the device can be switched on. The indicator lamp shows a
green light.
If the DENTALONE is used for the first time or after a long period out of operation, the internal
compressor is working initially until the operating pressure is reached. This process can take up to 20
seconds.
At this stage the console has to be brought into the working position. The procedure is as follows:
In the recessed grips at the left and right side of the console there are unlocking switches (17) and
through the activation of the rocker switches (Fig.10) the console (4) can be electrically unlocked.
(works only when the DENTALONE is turned on and the device has power)
Page 15 of 54
By activating the rocker switches (see illustration (fig.10) and pulling at the recessed grips on both sides
the operating console (4) can manually be moved upwards until it is audibly locked in the working
position, as soon.
After pressing both locking switches (17) and unlocking the console (4) (audible click), the console has to
be lifted within 1.5 seconds to raise it from the lower position into the upper position. Otherwise, the lock
function is activated automatically again. In this case both locking switch (17) must be released again and
process must be repeated. The same applies to lowering the console.
You should remove the moulded foam part (16), which is placed on the console (4) for protecting and
safeguarding the instruments and store it for future transports.
Please check after transport whether the instruments are still placed properly and in the correct order in
the instrument holder (18) (from left to right: Scaler (19); Micro-motor (20); Multifunction syringe (22);
Saliva ejector (23)). Refer to fig.9.
Then swivel the instrument holder (18) by gently pulling on the control panel (21) in a comfortable working
position until it is audibly locked. (fig.10).
There are 2 additional stop positions which facilitate an individual positioning, so that the instruments can
comfortably be taken out and the display i of the control panel (21) can be easily seen (fig.11).
fig.10
fig.11
Please check whether all instruments are completely assembled.
Check your device for completeness in accordance with the delivery notes.
The footswitch (3) is located in a holder mounted side on in the lower part of the device. (fig.7).
Remove the foot switch from its holder and connect it to foot switch socket (2) at the left side of the device
(fig.3 and fig.4).
Before every operation check the device for proper condition.
This concerns the stability of the unit, the two-sided lock in the extended position of the console as well as
the measures described in the following sections of these instructions. All cables, tubings and the suctino
hose should be checked for any damage.
Furthermore , the instrument detection and function of the instruments and also the default settings on
the control panel should be checked. (see section 8.5 and annex A (control panel))
Before the initial operation always check whether there is enough clean water in the water tank and the
suction container (12) is empty.
8.3

After unscrewing the screw cap from the bottle any remaining water should be disposed and the container
has to be thoroughly cleaned according in accordance with applicable guidelines.
The water tank (8) should to be disinfected before refilling in accordance with applicable guidelines.
(Refer to section 9.5)
Only use drinking water quality water suitable for dental equipment must be used.
The maximum capacity of the tank is 500 ml
Before closing the bottle also the screw cover has to be cleaned, disinfected and checked for correct
seating of the lid gasket. Please screw the cap hand-tight. Do not overtighten!
Now the water tank can be attached again to the quick release fitting and the Spray switch (15) can be
switched back on.
The compressor will start again to establish the operating pressure
8.4 Completion and arrangement of instruments
During transport of the device all sterile parts of instruments, i.e. Scaler and Scaler Tips, motor
handpiece; the tips of the syringe and the saliva ejector have to be packed separately and must be fitted
again by the user.
See the detailed instructions in section 8.6.and annex B (Scaler) and annex C (Motor).
The instrument holders, as already described in section 8.2, have been located with functionality and
ergonomic operation in mind
The instruments may not swapped between holders, because this would cause malfunctions!
Each day before the first treatment each instrument should be activated 30 seconds in order to rinse
stagnant water in instrument hoses.
Initial operation and practice interruption of more than 24 hours
 Before the initial operation and before and after each treatment pause (> 10 hours), disinfection,
cleaning, sterilization has to be carried out! (See section 9.)

Observing the rotation speed recommendations leads to optimum performance.
When exceeding the maximum permissible rotation speed some instruments are prone to can
lead to damage or destruction of instruments
In case of work component diameters which are bigger than the shaft strength strong centrifugal
forces can occur which can lead to deflections of the shaft and/or breakage of the instrument. Do
not exceed the maximum permissible rotation speed.
Please refer to manufacturers instructions to ascertain the maximum permissible rotation speed
of respective instrument.
Avoid excessive pressing forces, because this causes damage of the cutting instruments and
generates excessive heat.
Overheating is caused by excessive pressure on the instrument which leads damage of the pulp.
Excessive pressure can also lead to rough surfaces and. breakages of instruments
To avoid unwanted heat generation a sufficient cooling with an air/water spray (at least 50
ml/min) has to be guaranteed.
Insufficient water cooling causes irreversible damage of the tooth and tissue. In case of failure of
the compressed air generation, the treatment must be stopped immediately.
Blunt burs generate excessive heat and cause damage of the pulp.
Bent instruments not running smoothly have to be disposed of immediately.
Disinfection and sterilisation has to performed in accordance with Manufacturers
recommendations and applicable guidelines.
Before the first use and immediately after each use rotating instruments have to be cleaned and
where appropriate sterilized/autoclaved. Until the first use the instruments should be stored in the
original packaging or transport container at room temperature in a dust- und humidity-protected
manner.
Rotating instruments should be stored hygienically on suitable stands or containers. The same
applies to sterilized instruments and instruments in sterilized packaging. Instruments MUST be
stored in a dust-, humidity-free environment with no risk of recontamination.
In case of non-corrosion resistant instruments disinfection and cleaning agents with corrosion
protection (non-corrosive) have to be used.
The contact with H2O2 (hydrogen peroxide) has to be avoided. Hard metal working components
are attacked and damaged. Reduction of lifetime.
Avoid temperature over 180°C. Exceeding 180°Cleads to a reduced lifetime.
Rotating instruments made from metal and non rust-proof instruments are attacked by the
thermo-disinfector. This leads to discoloration and a shortened lifetime.
Advices for use, duration of exposure and suitability of disinfection and cleaning substances for
certain types of instruments can be obtained from the manufacturer of the solution.

Operation principle
The sinusoidal electrical signal, at ultrasonic frequency (f>20 kHz) is generated by the generator. This
signal is applied to the piezoelectric ceramic, located inside the transducer. The piezoelectric ceramic
converts this signal into mechanical vibrations. These vibrations are at the same ultrasonic frequency as
the electrical signal. The mechanical vibrations are propagated towards the distal end of the transducer.
The „Tip“ insert, which is attached at the distal end of the transducer, vibrates at ultrasonic frequencies
and makes it possible to achieve the aimed purpose.

Caution for Tip Usage
Check the tip before use. (Dirt, Damage, Bending or Rust)
Do not exceed Maximum Power Level for tip as this may damage the tooth structure and/or tip.
Do not hit ceramic prosthesis with tip during scaling as this may damage the restoration and/or the tip
Do not touch metal or prosthetic crowns, except for removing them, as tip could break and fall into
patient’s mouth and could be inhaled.
Do not touch gingival, mucosa and/or skin as. It could cause damage and/or burn injury.
Do not sharpen and/or bend the tip. Tip may damage and not generate enough vibration during
scaling.
During use, tip will gradually wear away. As the tip wears the tip movement will change and decrease
operating efficiency. When performance level drops too far change the Tip( Use tip guide check card
for reference)
DO ENSURE when securing tip to use the tip trench as supplied to avoid inefficient performance.
DO ENSURE before attaching tip, cleanliness of the tip thread to avoid inefficient performance.
To avoid personal injury DO ENSURE tip is removed prior to disconnecting the handpiece.
If you feel the tip is not vibrating, remove it from the operative site and press the foot control again. If
this does not improve the condition, Ensure the Tip is secure, turn the power off and restart it.
When attaching a tip, always use gloves and NSK tip wrench as supplied.
Ensure that water volume on the adjuster of the unit must be "0", when you use a tip which does not
require irrigation.
The tip wrench is a consumable item. For reliable operation replace it annually.

Provided Scaler Tips
The end of the Tip is thin and for supragingival fine scaling
and interdental scaling. The round cross-section allows tooth
surfaces to be finished without causing damage. Set the level
less than "Power 5" at G mode.
Apply the top of the Tip on the tooth surface and gently move
it sideways in the same way as G8 Tip. (fig.4)
fig.4
Removal of supra and subgingival calculus. It provides easy
access to interdental spaces and narrow pockets. Set the
level less than "Power 5" at G mode.
Insert the top of the tip into the periodontal pocket and move
it slowly and gently. The top of the tip is sharp so that it could
remove tartar on long crowns and retracted gingival. (fig.5)
Clean periodontal pocket at low power. (Set the level less
than "Power 5" at P mode.)
fig.5
Removal of supragingival and interdental calculus. This tip
can be used in all quadrants and is very useful for the removal
of hard calculus. Set the level less than "Power 7" at G mode.
Apply the top of the tip on the tooth plane and move it
sideways finely along the neck of tooth. (fig.6)
fig.6
Caution
Tips are consumable products and subject to wear and tear. We recommend periodical replacement.
Please use the Varios Tip Card to check when tips need to be replaced.
Page 47 of 54
B6
How to use the “Varios Tip Card“
1) Place the neck of the tip in the cut out.
2) Check wear of the tip.
3) See the green, yellow and red line to check wear of the tip. *See below what each colour means.
To guarantee effective and safe used we recommended to replace tips when they meet the yellow
line (wear of 1 mm)
Tip Card
Green: No wear – Tip is OK
Tip replacement is not necessary
Yellow: Wear of 1 mm – Tip is showing some wear
Tip replacement is recommended
Handpiece
fig.7
Red: Wear of 2 mm – Tip is badly worn
Tip replacement is necessary
* The Varios Tip Card can be used to check the following tips:
G1, G4, G5, G6, G8, P1/P1D, P10 and P20
Caution
Tips are consumable products. The efficiency of
dental scaling degreases approximately 25%, when
the top of the Tip wears 1 mm and approximately
50%, when it is has worn
2 mm. In addition, the vibration condition changes
owing to the wear, which may damage tooth surfaces.
Check the tip wear condition with the
Varios Tip Card periodically and replace tips
frequently.
B7
Use of the optional tip cover S
Grip the tip cover S and put it over the tip.
To remove, grip the tip cover S and the handpiece and pull gently apart. (fig.9)
