Nomenclature Flashcards
G.V. Black Classification: Class I
pit and fissure surfaces on:
occlusal surfaces of molar/premolars
occlusal 2/3 of B and L surfaces of molars
lingual surface of incisors
G.V. Black Classification: Class II
proximal surfaces of premolars/molars (posterior)
two surfaces, ie. MO, DO, posterior teeth
G.V. Black Classification: Class III
proximal surfaces of incisors and canines (anterior), not involving the incisal angle
- below the contact
G.V. Black Classification: Class IV
proximal surfaces of anterior teeth involving the incisal angle
G.V. Black Classification: Class V
gingival 1/3 of the facial and lingual surfaces of all teeth not pit and fissure (class I)
G.V. Black Classification: Class VI
incisal edge of anterior teeth or occlusal cusp of posterior teeth
not common, not pit and fissure
Simple Classification
one tooth surface
Compound Classification
two tooth surfaces
Complex Classification
three + tooth surfaces
Line angle
where 2 walls meet
ie. mesiofacial
Point angle
where 3 surfaces meet (mesiobucco-occlusal)
Axial wall
Internal wall: Lateral to pulp
Pulpal wall
Internal wall: floor of the prep, superior to the pulp
External walls
Distal, Mesial, Facial, Lingual, Gingival
G.V. Black “order of procedure”: what is Outline Form?
the area of the tooth surface to be included in the finished preparation (perimeter)
- location and extent of caries, self cleaning areas, restorative materials, esthetics, 2’ factors
G.V. Black “order of procedure”: what is Resistance Form?
shape and placement of restoration walls
- to withstand functional forces and fracture - wall angulation, depth of prep, internal line angles, restorative material
G.V. Black “order of procedure”: what is Retention Form?
shape or form of prepped tooth to resist displacement through tipping/lifting forces
- wall friction, undercuts, retention, bonding - important in amalgams
G.V. Black “order of procedure”: what is Convenience Form?
allows adequate observation, accessibility, ease of operation to prep/restore
G.V. Black “order of procedure”: what is Toilet of Cavity?
remove debris from the walls, dry the tooth and prep, visual assessment and inspection
ICDAS caries Code 0
sound tooth structure
ICDAS caries Code 1
first visual change in enamel, hardly visible on wet surface; need to dry tooth to see
ICDAS caries Code 2
distinct visual change in enamel, visible without air drying
ICDAS caries Code 3
enamel breakdown; no dentin visible
ICDAS caries Code 4
established decay - dentin shadow (NOT cavitated into dentin)
ICDAS caries Code 5
distinct cavity with visible dentin
ICDAS caries Code 6
extensive distinct cavity with visible dentin
