What side (buccal or lingual) is the white dot on based on these two images?
|
Lingual (The 2nd slide is more anteriorly located and the dot moved towards the anterior as well. "Same Lingual")
|
|
Which side (lingual or buccal) is the white dot on?

Buccal (film B is more anterior but the dot is more posterior... opposite buccal)
|
|
Based on these two films, where (buccal or lingual) is the foreign object [indicated by the black arrow] located?
|
Buccal (Film B is more posterior than A [note the coronoid process in the lower right, indicating a more posterior position] yet the object has moved anteriorly. "Opposite Buccal")

|
Lingual (Film on right is more distal and the crown is more distal as well. Same Lingual)

|
Lingual (film B is more mesial and crown is more mesial, same lingual)
|
|
Is point O on the lingual or buccal surface?
|
Buccal (The film is shifted UP and O has shifted DOWN so it is opposite buccal)
|
|

|
Lingual (film more mesial, long canal is mesial, same lingual)
|
|
