Deck 4: Dentition

Question 1

In the Federation Dentaire Internationale (FDI) the symbol 36 represents the __________.

Answer 1

Permanent mandibular left first molar
The Federation Dentaire Internationale (FDI) system assigns a two-digit number to each deciduous or permanent tooth. No letters or duplicate numbers are used. The first digit indicates the quadrant and whether the tooth is permanent or deciduous. Each quadrant is symbolized by a specific first digit. The second digit depends on the position the tooth occupies relative to the midline. The lowest number is assigned to the tooth closest to the midline.

Question 2
