OSCE Flashcards
CAUSE OF ANGINA
reversible narrowing of coronary arteries
SYMPTOMS OF STABLE ANGINA
pain during exercise that goes away with rest
unstable sees spontaneous pain
SYMPTOMS OF REVERSIBLE PULPITIS
discomfort to stimuli (cold and sweet) thats goes away within a few seconds once stimuli removed
should resolve once aetiology addressed - caries, deep restoration, exposed dentine
SYMPTOMS OF IRREVERSIBLE PULPITIS (SYMPTOMATIC )
sharp pain to thermal stimuli
pain can also be spontaneous, lingering, referred and accentuated by postural changes
OTC analgesics will not help
RCT indicated
POSITION OF PATIENT FOR EXTRACTIONS
lowers - upright
uppers - 45 degrees - 90 degrees
WHAT HEIGHT SHOULD PT BE AT FOR EXTRACTION
elbow height
TECHNIQUE FOR EXTRACTING MULTI ROOTED TEETH
buccal expansion and figure of 8
apical pressure
TECHNIQUE FOR EXTRACTING SINGLE ROOTED TEETH AND PREMOLARS
rotation
apical pressure
FUNCTION OF LUXATORS AND ELEVATORS
luxators - sever PDLs to create mobility
elevators - create space
HOW TO TELL DIFFERENCE BETWEEN COUPLANDS AND LUXATOR
couplands has sharp edge, luxator round
HOW TO USE COUPLANDS
wedge - downwards + mesial distal
Level - interprox - apical/ coronal
HOW TO USE CRYERS
wheel and axel
HOW TO USE LUXATOR
move from mesial to distal , buccal only
HAND POSITION FOR ELEVATORS AND LUXATORS
grip instrument with thumb and fingers round, index finger on shank for support and control
NAME 3 FUNCTIONS OF DENTAL DAM
moisture control
field isolation
airway protection
WHY MIGHT DENTAL DAM BE CONTRAINDICATED
breathing issues
pre - cooperative
WHAT NERVES INNERVATE UPPER TEETH
posteriors - posterior superior AN
premolars - middle SAN
anteriors - anterior SAN
WHAT NERVES INNERVATE THE PALATAL GINGIVA OF UPPER TEETH
3-3 = nasopalatine
4 back = greater palatine
WHAT NERVES INNERVATE BUCCAL GINGIVA OF UPPER TEETH
same as pulp - posterior, middle and anterior SANs
WHAT NERVES INNERVATE THE LOWER TEETH
all IAN , incisive branch does 1-4
WHAT NERVES INNERVATE BUCCAL GINGIVA OF LOWER TEETH
molars - buccal nerve
1-5 - mental nerve
WHAT NERVE INNERVATES LINGUAL GINGIVA OF LOWER TEETH
all lingual nerve
WHERE SHOULD PT BE SITTING FOR AN IANB
upright at correct height (elbow)
PURPOSE OF CENTRE LINE
incisor teeth set either side
DISTANCE BETWEEN LABIAL OF CENTRAL AND DISTAL INCISIVE PAPILLA
10mm
PURPOSE OF CENTRE OF ALVEOLAR RIDGE LINE
identifies location of lower posteriors
PURPOSE OF RESIDUAL ALVEOLAR RIDGE CONTOUR LINE
displays contour when ridge is covered by base
WHAT IS AN ALMA GAUGE USED FOR
determines vertical and horizontal position of anterior teeth relative to a specific point on the denture base e.g incisive papilla
MAXILLARY SUPPORT FOR DENTURES
palate and tuberosities
MANDIBULAR SUPPORT FOR DENTURES
buccal shelf and residual ridge
MAXILLARY DENTURE RELIEF AREAS
incisive papilla, palatine fovea, crest of ridge
MANDIBULAR DENTURE RELIEF AREAS
mylohyoid ridge, tori,
WHAT SIZE OF RECEPTOR FOR EACH RADIOGRAPH
bitewings and posterior periapical - size 2
anterior periapical - size 0
WHAT RADIOGRAPH SHOULD COTTON WOOL NOT BE USED
bitewings
MINIMUM FSD
200mm
RECOMENDED COLLIMATION
rectangular, lead
WHAT ACTIVE COMPONENTS REQUIRE ID TUBING
roberts retractor and buccal canine retractors
WHAT DIAMETER WIRE FOR AN ADAMS CLASP
0.7mm
WHAT PLIERS FOR AN ADAMS CLASP
number 64 pliers - 2 square tips
(one with one cone is 65’s)
WHAT 2 COMPONENTS WOULD YOU USE TO CORRECT AN ANTERIOR CROSSBITE
z spring and posterior bite plane
5 DISPLACEMENT FORCES
gravity, speech, tongue, mastication, ,active components
