 # Serial extractions are indicated when there is -

a) No skeletal discrepancy with dental crowding > 10 mm

b) No skeletal discrepancy with dental crowding between 5 - 7 mm.

c) Skeletal discrepancy >5°

d) Skeletal discrepancy >10° with dental crowding < 5mm

The correct answer is A. No skeletal discrepancy with dental crowding > 10 mm

 Serial extraction is indicated in cases of severe dental crowding. For this reason, it is best used when no skeletal problem exists, and the space discrepancy is large i.e., >10 mm per arch.

If the crowding is severe, little space will remain after the teeth are aligned, which means there will be little tipping and uncontrolled movement of the adjacent teeth into the extraction sites. If the initial space discrepancy is smaller, more residual space must be anticipated.
