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 .
