Isolation and File ID Flashcards
The ________ protects the patent
from swallowing or aspirating
instruments and materials.
rubber dam
• ESSENTIAL FOR ENDODONTICS • Defined as the “STANDARD OF CARE” • ANYTIME YOU DO NOT USE IT YOU ARE SIMPLY LIABLE WITHOUT DEFENSE
Rubber dam
• It is simply impossible to eliminate micro-organisms in the presence of saliva with its multitude of micro-organisms • ONLY a properly applied \_\_\_\_\_\_ can insure the absence of saliva in the surgical field
Dental
Dam
Failure to eliminate salivary leakage by proper
placement of the rubber dam creates _________ which has the potential of turning a
simple, routine, uncomplicated RCT into life threatening
cellulitis by introducing additional micro-organisms
which can greatly complicate the infection.
salivary
contamination
Is it ever okay to leave a tooth open?
NEVER; salivary contamination
If saliva is not effectively sealed by your dam
placement, you can be assured that ______ will leak
into the mouth as you irrigate.
NaOCl
Non-latex \_\_\_\_\_\_\_ is available in the Clinic and is necessary to prevent problems arising from latex allergies
Nitrile
Dam
Select a rubber dam which is radiolucent or radiopaque and
leave it in place when taking radiographs?
radiolucent
How many teeth should be isolated in endo?
only tooth treated
Rubber dam clamp # _____ is designed for an anterior tooth
212
the Clamp should rest at the cervical line ____
the height of contour to be adequately retained.
below HOC
T/F: Even after the Dam is released from the wings of the clamp, it may be
necessary to use some type of sealing agent to caulk around the tooth to
insure isolation.
True
_____ by Ultradent (available in dispensary) is being used to caulk
around the tooth to eliminate salivary contamination.
Oraseal®
T/F: If you cannot place an effective rubber dam, you cannot do a RCT on the tooth.
True
An _______ can be added as a matrix, for strength and to protect
against fracture.
orthodontic band
If patient is a copious saliva producer, you might consider Rx \_\_\_\_\_\_\_\_ 15 mg. (propantholine) ½-1 hour before appointment to control extraordinary salivary flow if not otherwise contraindicated by patient’s med. history
Pro-banthine
\_\_\_\_\_\_\_ file – Takes a sharper edge – Is fairly flexible up to #20 – Can be pre-curved easily to negotiate very curved canals (Retains the shape) – Increases geometrically in stiffness as diameter increases – Efficient when used by hand – Separates if overused or abused, usually with some warning ***
Stainless Steel Hand File
\_\_\_\_\_\_\_ file – Edge not as sharp (Motor-driven for efficient shaping) – Is extremely flexible (super- elastic but difficult to pre-curve) – Has nearly perfect shape memory (will NOT hold a curve) – Works efficiently in engine driven handpieces – Separates if overused or abused, usually with NO warning ***
Nickel-Titanium Motor Driven
\_\_\_\_\_ files: • Made of twisted tapered Stainless Steel Wire having a square, triangular or diamond shaped cross section. Basically are SCREWS
SS K-Type Hand Files
What is the color sequence for files after .10?
White Yellow Red Blue Green Black
Should you use continual clockwise motion for hand files?
No
____ files are basic to endodontic shaping. They are essential for:
- Scouting the canal (#10 or #08)
- Creating a Glide Path (#10 to patency and #15 to WL only)
- Bypassing a ledge, blockage or separated instrument
- Gaining length
Hand Files
As you increase file size up to .60, how much larger does the diameter get?
.05mm
As you increase file size over .60, how much larger does the diameter get?
.1 mm
