includes static zone (12-2 right handed, 10-12 left handed)
includes the mobile cabinet and large equipment
static zone

transfer zone
basic principles of instrument exchange
team effort (2)
dentist contributes most by standardizing procedure and working in a systematic manner
assistant contributed by anticipating
transfer zone (5)
front of the mouth and at chin level (not over patients head)
dentist must signal
dentist must stay in transfer zone
dentist should not have to move finger rest or eye focus
assistant should always have something ready to transfer
instrument exchange (3)
mirror and explorer at the beginning of each procedure
pick up the air/water syringe to dry tooth, then mirror
dentist in vitiates exchange by moving instrument slight away from the patients mouth

thumb, index and third finger
assistant positions new instrument parallel to the
instrument being used
working end pointed in direction of
use
little finger of the assistants left hand grasps the instrument at the
end opposite to the working end
single handed rotation
rotates used instrument
primary functions (3)
keep the back of the mouth fire from saliva, water and debris
retract the tongue and cheek away from the field of operation
reduce the bacterial aerosol caused by the hand piece
grasp (3)
right hand when assisting a right handed operator
pen grasp
palm-thumb grasp
posterior placement (3)
assistant positions the evacuator tip before the dentist
the opening is parallel to the tooth
posterior to tooth working
anterior placement (2)
top of the opening even with the occlusal/incisal surface
cotton roll placed in the vestibule between the teeth and cheek onto which the tip rests
operative procedures (2 phases)
preparation phase
restorative phase
SKIPPED preparation phase (9)
obtain restorative tray and needed supplies and place on cabinet top
review health and history and select anesthetic
attach handpicks and insert burs
assemble anesthetic syringe, topical, tofflemire matrix, and rubber dam\
seat patient and obtain and record vitals
position chair for field of operation
transfer mirror, explorer and dry the teeth and error with the air water syringe
anesthetic administered
area isolated with cotton products (ie cotton rolls or dry angles) or rubber dam
in preparation phase, tooth prepared with
hand piece and hand instruments
restorative phase (3)
dry prep and reisolate the area (using dry products)
apply bonding materials or desensitizing agents, liners
place matrix and wedges
certified dental assistant (2)
passes the dental assisting national board (DANB)
requires 12 continuing education hours a year to maintain CDA status
ring handed is usually at - oclock
3
left handed is usually at - o’clock
9
DA stool is - to - inches higher than operator
4-6 in
DA hips are at the patient’s
shoulders
feet rest on the — so the thighs are —
ring
parallel
DA stool arm at level of — and cabinet top over —
abdomen
thighs
basic principles of instrument exchange
firm, deliberate movements accomplished with minimum of motion involving only the fingers, wrist and elbow
the instrument is placed into the dentists hand by the assistant slightly rotating their hand and
lowering the instrument into the dentists hand
at the end of instrument transfer, (2)
the assistants hand exits the transfer zone to replace used instrument to tray
or
rotates used instrument into position for reuse (single handed transfer technique)
oral high evacuation (3)
primary functions
placement
grasp
in restorative phase, mix amalgam and load carrier or place composite capsule in extruder, then
transfer carrier/extruder, condensers, and sarvers
in restorative phase remove (2)
remove any matrix and wedge(s) and carve proximal
remove rubber dam or dry products (ie cotton rolls, dry angles)
at the end of restorative phase, (2)
check occlusion and transfer carver
