Rubber Dam Isolation Flashcards
What are the three main goals of isolating the operating field?
1) Moisture control
2) Retraction
3) Harm Prevention
Isolation is what?
Isolation is CRITICAL
What is the rubber dam isolating from?
1) Gingival crevicular fluid (sulcular fluid)
2) Saliva
3) Bleeding
4) Water spray
5) Debris
6) Materials/Instruments
What tissues are being depressed/retracted?
1) Gingival
2) Lips
3) Tongue
4) Cheeks
What is the main goal of retraction/access?
To provide maximum exposure of the operating site.
What is the main goal of harm prevention?
1) Prevent excessive saliva and/or moisture pooling
2) Prevents fluids and/or small instruments from being swallowed or aspirated
3) Prevents soft tissues from being cut or damaged.
What are some additional advantages of isolating and operating field?
1) A clean, dry operating field
2) Cleaner cavity preparation walls
3) Better visibility
4) Improved likelihood of restoration success.
What are other methods of isolation and moisture control?
1) High Velocity Evacuation (HVE)
2) Saliva Ejector
3) Cotton Rolls/Gauze
4) Iso-Dry/Iso-Lite
5) Antiosialagogues in conjunction with anesthetics
6) Rubber Dam
What does atropine sulfate do?
Supresses the bronchial and salivary secretions. Rarely used.
What does anesthetics do?
When profound, MAY decrease salivary flow. NO pharmalogical basis.
T or F. High Velocity Evacuation (HVE) removes all debris and moisture?
False. It removes most debris and moisture.
What is HVE usually utilized for?
Fixed prosthodontics procedures (crowns and bridges).
What is an alternative method to the saliva ejector?
The Svedopter.
T or F. Cotton Rolls/Gauze does not improve visibility and may easily obstruct the working area.
True.
What can connect to HVE and has a built in Bite Block?
Iso-Dry/Iso-lite
What are the advantages of Rubber Dam?
1) Effective for long appoinments
2) Dry, clean operating field
3) Improved visibility and access
4) Maximizes patient safety
5) Enhances patient comfort
6) Maximizes operator safety and effieciency
What are the disadvantages of Rubber Dam?
1) Time consumption
2) Patient Objection
3) Cannot be used for all patients
What kind of special conditions can a Rubber Dam not be used?
1) Partial eruption (unable to hold a retainer)
2) Malpositioned teeth
3) 3rd molars
4) Patients with impaired nasal breathing
5) Lesion position/location
What is the advantage of a thin rubber dam material?
Easy to apply and comfortable.
What is the advantage of a heavy rubber dam material?
Improved resistance to tearing and improved retraction.
What is the function of the retainer (clamps)?
To provide a stable anchor for the system at the most distal aspectb
What are the components of a retainer?
1) 4 prongs
2) 2 holes
3) Jaw
4) Bow
5) Wings (not present all the time)
What is the function of the frame?
To hold and stretch the RD material to improve visibility and help create a “space” for access.
What does each number hole in the hole punch correspond to?
#1: primary incisors #2: smallest incisors #3: maxillary central incisors, canines and premolars #4: large premolars/small to normal molars #5: large molars #6: large molars and the tooth to be clamped
