SECTION 6: INSTRUCTION OF OPERATION
It’s important to keep following points to use this system efficiently and to
avoid any mechanical trouble or dangerous condition.
Before using GP Obturation System, the dentists need to make good root canal
preparation with endo motor.
Requirement for good root canal preparation:
1. All the root canal should be made as straight as possible.
2. Root canals especially small collateral root canals should be cleaned as clean
as possible.
3. The dentists must possess root canal cleaner like sodium hypochlorite and
had better get a ultrasonic root canal cleaning device to make root canal clean
and smooth enough for obturation.
During Operation of vertical condensation with obturation pen:
1. The heat tips should be 4-5mm far from apex point of root canal.
2. The heat tips should be fixed with white slide caliper provided after
determining the length of root canal.
3. The gutta percha points (cone) should be 0.5-1mm shorter than the length
of root canal.
4 Root canal perforation should be avoided when heating. This is very very
important.
5. All heat tips are easily broken although the quality of heat tips is very good!
Heat tips are consumable!
When the dentists use obturation pen, they should be very tender and soft.
During Operation of backfilling with obturation gun:
Injection needles are also very fragile because it is made of silver!

Rev. 02/01/18 VER SMS-DYGP-PLUS-FREEFILL20170828-EN
15
The dentists had better not change angle of needle often, otherwise the needle
is easily broken!
They had better confirm two kinds of angle of needle: one is for upper teeth,
another is lower teeth.
In this way, the needle will be avoided bending to different angles often.
When running out of battery, the obturation gun can be still used directly with
power adapter for heating.
1. Pen tips, gun needles and heat insulators must be sterilized before
application and follow the instructions supplied with autoclave unit.
Sterilization cycle is recommended at 121 ℃(250 ℉) for 30 minutes or 131 ℃
(270℉) for 25 minutes.
2. The temperature of pen is preset at 120-220℃, and pen tip selection mode is
preset at F, FM, M,ML.
Adjust the working temperature and pen tip mode according to working
condition and pen tip size.
The maximum temperature of the gun is preset at 200℃. The dentists are free
to choose 160-200℃as per the requirements of GP bar with different brand.
3. Because pen has the characteristics of fast heating and cooling please
operate is carefully to avoid any accidents caused by burning.
4. The heater of the gun can be burnt out if there is no GP bar in the heating
chamber during the operation of the gun. Make sure to load the GP bar before
operating the gun.
5. It’s recommended to load just one GP bar at a time and to wait some times
for pulling the trigger. Because the warmed gutta percha has a little cushion.
Pulling trigger with excessive power may damage the groove on the plunger
and it maybe the reason that the gutta percha leak from the needle.
A. FreeFill Obturation Gun
The gun is designed to inject warmed gutta percha that is specially
formulated into the root-canal directly. It’s provides easy and fast filling, but it’s
recommended to use the pen to fill the apical part at first to avoid any
overfilling or under filling and the gun can be used for filling the remained part

aField strengths from fixed transmitters, such as base stations for radio
(cellular/cordless) telephones and land mobile radios, amateur radio, AM and
FM radio broadcast and TV broadcast cannot be predicted theoretically with
accuracy. To assess the electromagnetic environment due to fixed RF
transmitters, an electromagnetic site survey should be considered. If the
measured field strength in the location in which the [DY-GP Plus] is used
exceeds the applicable RF compliance level above, the [DY-GP Plus] should
be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the

Recommended separation distances between portable and mobile RF
communications equipment and the [DY-GP Plus]
The [DY-GP Plus] is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of
the [DY-GP Plus] can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the [DY-GP Plus] as
recommended below, according to the maximum output power of the
communications equipment.
