Q1. [Recall]
Which tooth class is primarily specialized for shearing and cutting functions due to its
incisal edge morphology?
A. Molars
B. Premolars
C. Incisors
D. Canines
✅ Answer: C
📝 Rationale: Incisors are characterized by a sharp, flat incisal edge adapted for cutting
food. Their morphology lacks cusps and instead presents a blade-like edge,
distinguishing them functionally and structurally from canines (tearing) and posterior
teeth (grinding).
Q2. [Comprehension]
Which feature best distinguishes canines from other tooth types in terms of crown
morphology?
A. Presence of multiple cusps
B. A single prominent cusp with a long crown
C. Flat occlusal surface with fissures
D. Broad occlusal table for grinding
✅ Answer: B
📝 Rationale: Canines are defined by a single, well-developed cusp and a tall crown,
adapted for piercing and tearing. This morphology distinguishes them from incisors (flat
edges) and premolars/molars (multi-cusped grinding surfaces).
Q3. [Application]
A tooth is recovered with two cusps of nearly equal size and a bifurcated root. Which
tooth type is most consistent with this morphology?
A. Maxillary canine
B. Mandibular incisor
C. Maxillary premolar
D. Mandibular molar
✅ Answer: C
,📝 Rationale: Maxillary premolars commonly exhibit two cusps (buccal and lingual) and
frequently have bifurcated roots. This combination of crown and root morphology is
diagnostic for identifying premolars in fragmentary remains.
Q4. [Analysis]
Which morphological feature provides the most reliable distinction between molars and
premolars in an isolated crown fragment?
A. Presence of an incisal edge
B. Number and complexity of cusps
C. Tooth coloration
D. Enamel thickness alone
✅ Answer: B
📝 Rationale: Molars typically have a greater number of cusps and more complex
occlusal morphology compared to premolars. This includes additional ridges and fissure
patterns, making cusp number and arrangement a key diagnostic feature in
identification.
Q5. [Comprehension]
Which crown surface is defined as facing toward the midline of the dental arch?
A. Distal
B. Buccal
C. Mesial
D. Lingual
✅ Answer: C
📝 Rationale: The mesial surface is oriented toward the midline of the dental arch, while
the distal surface faces away. This directional terminology is fundamental in describing
tooth morphology and position.
Q6. [Application]
During analysis, a ridge connecting two cusps across the occlusal surface is observed.
What is this structure called?
A. Cervical line
B. Marginal ridge
C. Transverse ridge
D. Root trunk
,✅ Answer: C
📝 Rationale: A transverse ridge forms when two triangular ridges from opposing cusps
meet across the occlusal surface. This structure is important in identifying occlusal
morphology and functional anatomy of posterior teeth.
Q7. [Analysis]
Which feature is most indicative of functional occlusal complexity in molars?
A. Smooth enamel surface
B. Absence of fissures
C. Presence of fissures and grooves between cusps
D. Uniform crown thickness
✅ Answer: C
📝 Rationale: Molars exhibit fissures and grooves separating cusps, which increase
occlusal efficiency for grinding. These features reflect complex occlusal anatomy and are
key indicators of functional adaptation.
Q8. [Recall]
Which dental tissue forms the outermost covering of the crown?
A. Dentine
B. Cementum
C. Enamel
D. Pulp
✅ Answer: C
📝 Rationale: Enamel is the highly mineralized outer layer covering the crown. It provides
protection against mechanical wear and is the hardest tissue in the human body.
Q9. [Comprehension]
Which tissue is primarily responsible for transmitting sensory stimuli within the tooth?
A. Enamel
B. Cementum
C. Pulp
D. Dentine
✅ Answer: C
📝 Rationale: The pulp contains nerves and blood vessels, making it the primary tissue
responsible for sensory perception and vitality within the tooth.
,Q10. [Analysis]
Which structural difference best distinguishes cementum from enamel?
A. Enamel is vascularized
B. Cementum covers the crown
C. Cementum is less mineralized and covers the root
D. Enamel contains collagen fibers
✅ Answer: C
📝 Rationale: Cementum is a bone-like tissue covering the root and is less mineralized
than enamel. It serves as an attachment site for the periodontal ligament, unlike enamel,
which is highly mineralized and covers the crown.
Q11. [Fill-in-the-Blank MCQ – Application]
The surface of a tooth facing the cheek is referred to as the ______ surface.
A. Lingual
B. Mesial
C. Buccal
D. Distal
✅ Answer: C
📝 Rationale: The buccal surface faces the cheek in posterior teeth, while anterior teeth
may use the term labial. This directional terminology is essential for anatomical
description.
Q12. [Fill-in-the-Blank MCQ – Recall]
The tissue that forms the bulk of the tooth structure beneath enamel is ______.
A. Pulp
B. Cementum
C. Dentine
D. Enamel
✅ Answer: C
📝 Rationale: Dentine constitutes the majority of the tooth’s structure, providing support
to enamel and housing microscopic tubules connected to the pulp.
,Q13. [Fill-in-the-Blank MCQ – Comprehension]
In the FDI notation system, the first digit represents the ______.
A. Tooth type
B. Quadrant
C. Root number
D. Tooth size
✅ Answer: B
📝 Rationale: The FDI system uses the first digit to identify the quadrant and the second
digit to specify the tooth position within that quadrant, making it useful in forensic and
clinical contexts.
Q14. [Fill-in-the-Blank MCQ – Analysis]
The region where roots diverge in multi-rooted teeth is known as the ______.
A. Apex
B. Cervix
C. Furcation
D. Ridge
✅ Answer: C
📝 Rationale: The furcation is the anatomical area where roots split in multi-rooted teeth,
and it is an important diagnostic feature in identifying molars.
Q15. [True/False – Recall]
Deciduous teeth generally have thinner enamel and dentine layers compared to
permanent teeth.
✅ Answer: TRUE
📝 Rationale: Deciduous teeth are characterized by thinner enamel and dentine, which
contributes to their lighter appearance and faster wear compared to permanent teeth.
Q16. [True/False – Comprehension]
All molars have a single root.
✅ Answer: FALSE
📝 Rationale: Molars typically have multiple roots (e.g., maxillary molars often have
three), which increases anchorage and supports their role in heavy mastication.
, Q17. [True/False – Application]
The periodontal ligament connects the tooth root to the alveolar bone.
✅ Answer: TRUE
📝 Rationale: The periodontal ligament is a fibrous connective tissue that anchors the
tooth to the alveolar bone, allowing slight movement and absorbing mechanical forces.
Q18. [True/False – Analysis]
The Universal notation system is primarily used in international forensic contexts.
✅ Answer: FALSE
📝 Rationale: The Universal system is mainly used in the United States, whereas the FDI
system is internationally recognized and preferred in forensic and global contexts.
Q19. [Scenario-Based – Application]
An isolated tooth fragment shows three distinct roots and a broad occlusal surface with
multiple cusps. Which identification is most likely?
A. Mandibular premolar
B. Maxillary molar
C. Mandibular incisor
D. Maxillary canine
✅ Answer: B
📝 Rationale: Maxillary molars typically have three roots and complex occlusal
morphology with multiple cusps. These features are diagnostic in distinguishing them
from other tooth types in fragmentary assemblages.
Q20. [Scenario-Based – Analysis]
A fragmented tooth shows a single root, a sharp cusp, and a long crown. In a forensic
context, which conclusion is most defensible?
A. It is a molar used for grinding
B. It is an incisor used for cutting
C. It is a canine adapted for tearing
D. It is a premolar with bifurcated roots
✅ Answer: C
📝 Rationale: The combination of a single root, prominent cusp, and elongated crown is
characteristic of canines. These features reflect their functional role in tearing and are
distinct from other tooth classes.
