Question 1
In the FDI numbering system, a permanent maxillary right first
molar is:
A) 16
B) 17
C) 26
D) 46
Correct Answer: A
*Rationale: In the FDI (Fédération Dentaire Internationale) two-
digit system, the first digit indicates quadrant (1 = maxillary
1
,right, 2 = maxillary left, 3 = mandibular left, 4 = mandibular
right). The second digit indicates tooth number from midline (1 =
central incisor to 8 = third molar). Therefore, maxillary right first
molar is 16 .*
Question 2
Which tooth numbering system does NOT use letters when
describing primary dentition?
A) Universal System
B) Palmer Notation
C) FDI Numbering System
D) ISO System
Correct Answer: C
*Rationale: The FDI system uses two-digit numbers for both
permanent and primary dentition without letters. Primary teeth in
FDI use quadrants 5-8 (e.g., 51 = maxillary right primary central
2
,incisor). The Universal system uses letters A-T for primary teeth,
and Palmer uses letters for primary teeth .*
Question 3
What is the periodontium?
A) The hard tissue covering the anatomical crown
B) The oral hard and soft tissues that support the teeth
C) The nerve and blood supply to the tooth
D) The visible portion of the tooth in the mouth
Correct Answer: B
Rationale: The periodontium consists of all supporting structures of
the tooth, including the gingiva (free and attached), periodontal
ligament, cementum, and alveolar bone. These tissues work
together to anchor the tooth and maintain its position .
Question 4
When looking into a healthy oral cavity, what will you most likely
see?
3
, A) The anatomical crown
B) The clinical crown
C) The root
D) The cementoenamel junction
Correct Answer: B
Rationale: The clinical crown is the portion of the tooth visible in the
oral cavity above the gingival margin. The anatomical crown
extends from the cementoenamel junction (CEJ) to the
occlusal/incisal edge, but part of it may be covered by gingiva in
a healthy mouth .
Question 5
Which tooth tissue most closely resembles bone?
A) Enamel
B) Dentin
C) Cementum
D) Pulp
