Question 1
According to G.V. Black's classification, a Class II cavity involves
which tooth surfaces?
A. Occlusal surface only
B. Occlusal and smooth surfaces (proximal) of posterior teeth
C. Facial or lingual surface of anterior teeth
D. Incisal edge of anterior teeth
Correct Answer: B (Occlusal and smooth surfaces (proximal)
of posterior teeth)
Rationale: Class II cavities involve the proximal (mesial or distal)
surfaces of premolars and molars, often including the occlusal
1
,surface for access. Class I is pits/fissures, Class III is proximal of
anterior without incisal involvement, Class IV includes incisal
angle.
Question 2
During amalgam condensation, the primary purpose of using a
small condenser is to:
A. Remove excess mercury
B. Adapt amalgam to cavity walls and margins
C. Carve occlusal anatomy
D. Polish the restoration
Correct Answer: B (Adapt amalgam to cavity walls and
margins)
Rationale: Small condensers allow access to line angles and
cavosurface margins to ensure proper adaptation. Large
2
,condensers are for bulk condensation. Carving and polishing are
separate steps.
Question 3
When placing a Tofflemire matrix band for a Class II amalgam
restoration, the band should be contoured to:
A. Fit the buccal and lingual contours of the tooth
B. Be perfectly straight
C. Cover only the gingival floor
D. Extend 5mm below the gingival margin
Correct Answer: A (Fit the buccal and lingual contours of the
tooth)
Rationale: Contouring the band replicates the natural emergence
profile and prevents overhangs. A straight band creates gaps or
ledges at the margins.
3
, Question 4
The "look and feel" of properly triturated amalgam is:
A. Dry and crumbly, no shine
B. Wet and shiny with a homogenous, dough-like consistency
C. Runny and mercury-rich
D. Hard and fully set within 30 seconds
Correct Answer: B (Wet and shiny with a homogenous,
dough-like consistency)
Rationale: Proper trituration produces a homogenous, shiny mix
that is workable. Over-triturated amalgam is dry/crumbly;
under-triturated is mercury-rich and weak.
Question 5
The wedge placed interproximally under a Tofflemire matrix
band serves to:
A. Only separate teeth
