Correct answer: B — 2-1-2-3 / 2-1-2-3
The dental formula for one quadrant of the permanent human dentition is 2-1-2-3 (2 incisors, 1 canine, 2 premolars, 3 molars), giving 8 teeth per quadrant × 4 quadrants = 32 teeth total. The primary dentition formula is 2-1-0-2 (2 incisors, 1 canine, 0 premolars, 2 molars) = 5 per quadrant × 4 = 20 teeth. Note: premolars replace primary molars; permanent molars have no predecessors.
