Deck 4: Dentition

Question 1

Tooth #65 is the code for the

A) permanent mandibular right second premolar
B) deciduous mandibular left second molar
C) deciduous maxillary left first molar
D) deciduous maxillary right second molar
E) none of the above

Answer 1

E
In the Federation Dentaire Internationale (FDI)system tooth #65 is the deciduous maxillary LEFT second molar.Note that selection "d" is incorrect because it is on the wrong side of the mouth.All identification systems view teeth as if the practitioner is looking at the face from the outside.

Question 2

In the Universal System,#9 refers to the permanent maxillary left central incisor.In the Universal System,#29 refers to the permanent mandibular first right molar.

A) Both statements are true.
B) The first statement is true;the second statement is false.
C) The first statement is false;the second statement is true.
D) Both statements are false.

Answer 2

B
In the Universal System the maxillary left central incisor is identified as tooth #9.Tooth #29 refers to the permanent right second premolar.The Universal system utilizes numbers 1-32 to identify the permanent teeth.This system begins with the maxillary right third molar as tooth number 1 and proceeds across the arch to the maxillary left third molar,which is tooth number 16.The system then identifies the mandibular left third molar as tooth number 17 and proceeds across the arch to mandibular right third molar,tooth number 32.

Question 3

Permanent first molars are succedaneous teeth.

Answer 3

False
Permanent teeth that replace or succeed the deciduous teeth are called succedaneous teeth.Because permanent molars do NOT have predecessors,and they do NOT succeed or replace deciduous teeth,they are considered nonsuccedaneous teeth.
