What is the usual order for extraction of teeth if serial extraction is chosen?

  1. Primary canine > Primary first molar > Permanent first molar

  2. Primary first molar > Primary canine > Permanent first molar

  3. Permanent first molar > Primary canine > Primary first molar

  4. Primary canine > Permanent first molar > Primary first molar

The correct answer is: Primary canine > Primary first molar > Permanent first molar

Serial extraction is a treatment approach where the primary canine is extracted first, followed by the primary first molar and then the permanent first molar. This sequence allows for proper alignment of the permanent dentition as the eruption progresses. In this case, option A, which states "Primary canine > Primary first molar > Permanent first molar," is the correct sequence for serial extraction. The other options are incorrect because they do not follow the typical order of teeth extraction in the context of serial extraction.
