ISOLATION METHODS Flashcards
GOALS OF ISOLATION
→ moisture control
→ retraction and access
→ harm prevention
→ safe and aseptic operating field
→ prevent accidental swallowing of materials and instruments
→ bacterial contamination from saliva
→ local anesthesia
→ comfort
→ protecting from swallowing or aspirating foreign bodies
→ protection of soft tissues
ADVANTAGES OF ISOLATION
FOR THE PATIENT
→ dry and clean operative field
→ infection control
→ increased accessibility to the operative site
→ improved properties of restorative material
→ improved visibility
→ prevention of contamination of tooth preparation
ADVANTAGES OF ISOLATION FOR THE OPERATOR
used in endodontics for root canal treatment but also in
operative dentistry
RUBBER DAM ISOLATION
RUBBER DAM ISOLATION is made by?
made in 1864 by Sanford C. Barnum

OPTRA DAM
can be placed in all labial, buccal and lingual areas being
worked on except the frenum area
COTTON ROLL
→ mainly placed on the cheek side
→ not to be placed on lingual side
ABSORBENT PADS OR CELLULOSE WAFER
used to dry a cavity preparation especially in deep cavities
that are sensitive to air drying
COTTON PELLETS
serves as a catch or net for restorative materials
THROAT SHIELDS
able to remove not just moisture but also aerosol
HIGH VOLUME EVACUATORS (HVE)
→ can be autoclavable or disposable
→ placed opposite to the handpiece/working instrument
HIGH VOLUME EVACUATORS (HVE)
only good for moisture (saliva) and not aerosols
SALIVA EJECTORS
→ used to separate marginal gingiva from tooth preparations
→ prevent trauma to gingiva
RETRACTION CORDS
not for patients with TMJ concerns
MOUTH PROPS
