Rubber Dam Isolation Flashcards
The anchor tooth should be __ teeth posterior from the tooth being operated on
2
The clamp should contact the tooth at __ points
4
What are the advantages of using a RD
- Enables clean and dry operating field
- Improved visual access
- Possibility to work faster without interruptions
- Comfortable for the patient
- Prevents contamination with saliva, debris, blood and chemicals
- Prevents aspiration
A RD should be used for every __(what kind of) procedure
adhesive
(T/F) There are three RD thicknesses (thin, medium, and thick)
t
For the RD hole punch the hole for the anchor tooth should be
the largest
The first three largest holes are used for what type of teeth
molars
What hole is used for premolars and canines
4th
What hole is used for Max. incisors
5th
What hole is used for Mand. incisors
6th (smallest)
Where on the tooth is the camp place
at the HOC
What in the point of using a RD clamp
- Holds RD in place
- Retracts gingival tissues
- Provides cervical access
The bow of the clamps sites at the (mesial/distal)
distal
A W2 clamp is used for…
Premolars and maxillary incisors (narrow jaws for smaller teeth)
A W3 clamp is used for
Premolars and small molars (flat jaws)
A W8 clamp is used for
Normally erupted maxillary molars
A W7 clamp is used for
Normally erupted mandibular molars
A W8A clamp is used for
Small/partially erupted molars (jaws angled down)
A 212 clamp is used for
Class V isolation of incisors, canines, bicuspids (Jaws are more gingival on the buccal)
(T/F) it is okay to put the jaws of a clamp close to a lesion
F- it may collapse and limits accessibility
When punching a hole for the 212 clamp the ole should be placed slightly….
facial
Why do we punch the hole for a 212 clamp facial
to prevent excess RD material at the facial
In operative dentistry, __ is isolated with a RD verse endo where a __ is isolated
quadrant… single tooth
What are the 3 things you should before RD isolation
- Anesthesia
- Shade selection
- Check occlusal contacts (if restoring an occlusal surface)
Why should you select the shade of the tooth before RD placement
Tooth dehydrates quickly with RD
As mentioned before the Jaws of the clamps contact the tooth in 4 spots, where are these contacts?
2 buccal 2 lingual
What is used to stabalize a RD in the anterior
Wedjet or double floss
What are some reasons why you may not be able to use a rubber dam
- Partially erupted teeth that can’t support a clamp
- 3rd molars
- Malposistioned teeth
- Patients with asthma (difficulty breathing through nose)
- Psychological reasons
- Latex allergy
Alternatives to RD isolation
- Cotton rolls
- 2x2 gauze
- Isoshelid (dry angles) –> block the parotid to keep area dry
- Saliva ejector
- Spandex
- Retraction cord (may be necessary for sub gingival decayer non-retentive crown shape)
