5
How many roots do the 1.7 and 2.7 have?
3
You have been tasked with charting existing restorations on a new patient, age 20 years old. She had previous orthodontic treatment and only one maxillary premolar is present on each side. How can you tell whether the first or second premolar had been extracted for the orthodontic treatment?
If the remaining tooth has two roots, the 2nd premolars were extracted
In anatomical position the:
