BDS 2nd Year DADH MCQs: Important Questions & Answers

Tooth numbering systems are used to identify individual teeth based on their position in the dental arch. BDS 2nd Year DADH MCQs on this topic can help students practise identifying teeth using different notation systems.

This practice set covers questions based on the Universal Tooth Numbering System, FDI two-digit system, Zsigmondy-Palmer System, and primary tooth notation. The questions are based on the provided DADH question set.

BDS 2nd Year DADH MCQs on Tooth Numbering Systems

The following questions cover tooth identification using different numbering systems, including permanent and primary teeth.

Q1. In the Universal Tooth Numbering System, which number represents the permanent left maxillary second molar?

(A) 2
(B) 15
(C) 31
(D) 18

Answer: (B) 15

The permanent left maxillary second molar is designated as 15 in the Universal system.

Q2. A tooth is recorded as 36 using FDI notation. What is its corresponding number in the Universal system?

(A) 18
(B) 19
(C) 30
(D) 31

Answer: (B) 19

FDI 36 represents the mandibular left first molar. In the Universal system, the same tooth is numbered 19.

Q3. In the FDI two-digit system, what does the first digit 7 indicate?

(A) Permanent mandibular left quadrant
(B) Primary maxillary left quadrant
(C) Primary mandibular left quadrant
(D) Primary mandibular right quadrant

Answer: (C) Primary mandibular left quadrant

The FDI system uses digits 1 to 4 for permanent teeth and 5 to 8 for primary teeth. The digit 7 represents the primary mandibular left quadrant.

Q4. A patient has pain in the left mandibular posterior region with restricted mouth opening. Which FDI tooth number is most likely involved?

(A) 18
(B) 28
(C) 38
(D) 48

Answer: (C) 38

The solution identifies 38 as the left mandibular third molar, matching the clinical description in the question.

Q5. Which FDI numbers represent the left-side first premolars of the upper and lower arches?

(A) 14, 24
(B) 24, 34
(C) 34, 44
(D) 14, 44

Answer: (B) 24, 34

The left maxillary first premolar is 24, while the left mandibular first premolar is 34 in the FDI system.

Q6. What is the Universal Tooth Numbering System equivalent of FDI tooth 38?

(A) 1
(B) 16
(C) 17
(D) 32

Answer: (C) 17

FDI tooth 38 represents the left mandibular third molar. The corresponding Universal number is 17.

Q7. In the Universal Numbering System for primary teeth, which tooth is designated by the letter N?

(A) Mandibular left central incisor
(B) Mandibular left lateral incisor
(C) Mandibular right central incisor
(D) Mandibular right lateral incisor

Answer: (B) Mandibular left lateral incisor

Primary teeth are labelled from A to T in the Universal system. In the mandibular left sequence, N represents the lateral incisor.

Q8. Which tooth numbering system is also called the “Symbolic System”?

(A) Universal System
(B) FDI System
(C) Zsigmondy-Palmer System
(D) Haderup System

Answer: (C) Zsigmondy-Palmer System

The Zsigmondy-Palmer System as the “Symbolic System” because it uses a grid to represent the quadrants.

Q9. A carious tooth in the upper left posterior region is associated with a periapical infection affecting the maxillary sinus. Which FDI number identifies the affected first molar?

(A) 16
(B) 26
(C) 36
(D) 46

Answer: (B) 26

The upper left first molar is represented by 26 in the FDI notation system.

Q10. According to the FDI tooth notation system, what does 74 represent?

(A) Primary mandibular left first molar
(B) Primary mandibular right first molar
(C) Primary mandibular left second molar
(D) Primary mandibular right second molar

Answer: (A) Primary mandibular left first molar

FDI number 74 represents the primary mandibular left first molar.

Q11. Which FDI number represents the maxillary left central incisor?

(A) 11
(B) 21
(C) 31
(D) 41

Answer: (B) 21

The maxillary left central incisor is designated as 21 in the FDI notation system.

Q12. In the Universal system, which tooth is represented by number 27?

(A) Mandibular right canine
(B) Mandibular left canine
(C) Mandibular right first premolar
(D) Mandibular right lateral incisor

Answer: (A) Mandibular right canine

Universal number 27 represents the mandibular right canine.
