4. The Touch 'n Heat Model 5004
probe handle has special features.
The pinvise nut (1) provides a convenient holder for the different
tips. The contact spring (2) on the pinvise nut allows you to
activate the Touch 'n Heat from any direction while wearing
gloves. When you want to heat a tip, depress the spring so that
it contacts the shaft (3).
5. Using the selector button.
Whenever the unit is not being used, it should be put in the
STORE mode with the selector button. The unit is deactivated
in the STORE mode, preventing battery from draining. This
will also prevent the tip from heating in case the touch switch
is activated accidentally. This feature should always be used
when changing tips.
Touch 'n Heat User Guidelines
1. Installing the tip.
Put the unit in the STORE mode using the panel switch.
Loosen the pinvise nut a few turns and insert the tip as far
as it will go. The thicker part of the tip should disappear into
the pinvise. Hand tighten the nut. Adjust the intensity to
your desired setting.
2. Tip life depends on temperature.
The tips have life expectancies which greatly depend on the
operating temperature. At the maximum heat setting, the heat
carrier will run between 1200 and 1400°F . The tip life at this
temperature is short. If the average operating temperature is
lower, the heat carrier's life expectancy dramatically increases.
All tips will gradually lose their heating efficiency over a period
of time.
3. Temperature versus power setting.
The temperature of a certain type of tip depends on its size
and the applied heating power. The smaller the tip, the higher
the temperature will be at a certain power. The following graph
shows the temperature curves for the various tips when they
are operating in open air.

4. Touch mode operation.
The touch mode has the advantage of making it possible for
you to enter the tooth with a cool instrument and then rapidly
heat the gutta-percha inside the tooth. Since the instrument
remains hot, the gutta-percha releases without sticking. The
recommended power setting for the touch mode is in the range
of 6 to 10, depending on the technique used. On the other hand,
if you want to remove gutta-percha, simply use a lower power
setting or let the tip cool down in the canal so that the gutta-
percha adheres to the tip.

Tips and Accessories
All tips are heated using a patented method with the heat
generated close to the tip's point. The accessories available for the
Touch 'n Heat include a flat spoon, two plugger sizes, narrow and
standard anterior or posterior heat carriers plus a hot pulp test tip.
1. Using the pluggers.
The narrow plugger (0.5mm) is similar to the narrow posterior
but has a flat end instead of being pointed. Many practitioners
use this tip in the vertical condensation technique. They claim
it is easier to remove gutta-percha with this tip than with the
narrow posterior tip. The thick plugger (1.0mm) is used to
prepare post space.
2. Using the Hot Pulp Test Tip (HPTT).
The HPTT is used to test for heat sensitivity. It is important to
use some medium to transfer the heat from the pulp test tip to
the tooth. A ball of gutta-percha may be softened and molded
around the tip edges. Dip the gutta-percha ball in talcum
powder or vasoline to prevent it from sticking to the tooth.
Consult the temperature/power chart for your desired power
setting. Place the tip in firm contact with the tooth, making sure
a good contact is established. The black heat shielding tube on
the HPTT minimizes your risk of burning the patient.
Frequently Asked Questions about the Touch 'n Heat
1. What size is the smallest tip?
The smallest tip we have are the narrow posterior and the
narrow anterior tips. They both correspond to a #40 file. The
straight portions of the posterior and the anterior tips are
18 mm and 21 mm, respectively. They are made from material
of the same taper.
2. How hot can a tip get?
At maximum power, a tip in the air can reach 1200 to 1400°F in
approximately 8 seconds. You can adjust the heat down to about
100°F by using the lowest power setting. A chart included in the
instruction guidelines shows how the tip temperatures depend
on the power setting.
3. Isn't this high temperature dangerous?
Like a dental drill, needle or scalpel, the unit should only be
used by a trained professional. You should use the high heat
setting to sear off gutta-percha in the lateral condensation
technique where a cluster of cones are cut through. The high
heat is also useful in preventing gutta-percha from sticking to
the tip in the vertical condensation technique. The idea is to
transfer a relatively large amount of heat in a very short time
(1-2 seconds), so that the tip can be withdrawn while it is still
hot. On the other hand, if you want to remove gutta-percha,
you should use a lower heat setting; i.e., a cooler tip.
4. What is the normal power setting?
The maximum heat setting should be used only when searing
off gutta-percha. For the vertical condensation technique, we
recommend a power setting in the range of 6-8.
