2. All endodontic operation should be
performed under the rubber dam.
-1-It provides a dry, clean and
sterilizable field.
2-It protects the patient from
possible aspiration or swallowing
of tooth and filling debris, bacteria,
necrotic pulp remnants of
operating materials.
3-It protects the patient from
rotary and hand instruments, drug
and the trauma of repeated
manual manipulation of the oral
tissues.
-4-It is faster, more convenient and
less frustrating than the repeated
changing of cotton rolls or saliva
evacuating devices
3. 5-It eliminates the interference,
annoyance and obscuring of vision by the
tongue and cheeks.
6-Dark color rubber dam material provides
more contrast between the tooth color and
the dam material color, while lighter color
provide more illumination of the operative
field.
7-Prevent talkative patient from wasting
the chair side time
4. I-Rubber dam material
-Rubber dam material is available
in precut squares or in rolls, in
light – or dark colored material
and in a number of
thicknesses.
-The medium weight material can
be adjusted to retract the soft
tissues and it is
recommended.
-This material has the proper
elasticity to hug the tooth
being isolated and providing a
hermetic seal without the use
of floss ligature tied around
each tooth.
5. -Also, it does not tear or rap easily and
provides an unusual degree of protection
from injury for the underlying soft tissues.
-It exerts a greater retracting force on the
lips and cheeks than the thinner materials,
thus, affording greater access and
improved vision.
6. -The lighter weight material tends to tear
easily and the heavy weight dam places too
much tension on the clamp. Often resulting
in dislodgment.
7. II-Rubber dam frames:
-It is used to hold the
dam in a manner that
allows retraction of the
cheeks and providing
unobstructed access
to the tooth to be
treated.
10. -For endodontic therapy
particularly, the use of
clamps with wings allows
a more rapid and efficient
means of applying the
rubber dam.
-The wings allow the dentist
to place the clamp, dam,
and frame in one
operation.

PM.,No.26&No.14 A for M
12. IV-Rubber dam punch
-The rubber dam punch must be
convenient in use and creates
a sharp hole in the dam
material.
-Failure to create a sharp hole
in the dam material, will result
in the contamination of the
field owing to salivary leakage
at the site of the ragged hole
in the dam.
13. V-Rubber dam forceps
-The rubber dam
forceps is used
to carry the
rubber dam
clamps on the
involved tooth
