In serial extraction, the most common order of tooth removal is

Primary canine, primary M1, permanent premolars
Primary M1, primary canine, permanent premolars
Permanent premolars, primary canine, primary M1
Primary canine, permanent premolars, primary M1

The correct answer is: Primary canine, primary M1, permanent premolars

In serial extraction, the most common order of tooth removal is primary canine, primary M1, permanent premolars. This order is chosen because it allows for proper alignment of the remaining teeth and facilitates easier treatment with orthodontics. Removing the primary M1 first would result in shifting of the primary canine and possible crowding of the permanent premolars. Removing the permanent premolars first would result in a longer treatment time with orthodontics due to the presence of the primary canine and primary M1. Removing the primary canine last would also result in a longer treatment time and possible difficulty in proper alignment of the teeth. Therefore, the correct order of tooth removal in serial extraction is essential for efficient and effective orthodontic treatment.
