Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. Difficulty cleaning teeth
The essential Orthodontics principle supports Difficulty cleaning teeth; it is the option that most directly explains the image characteristic, safe modality choice, or oral-health finding described.
Option by option
A. Difficulty cleaning teeth (correct)
Correct. Difficulty cleaning teeth matches the decisive detail in this sample.
B. Improved airway
Improved airway can be useful elsewhere but is not the best answer here.
C. Loss of salivation
Loss of salivation is unsupported by the imaging or dental information provided.
D. Automatic caries prevention
Automatic caries prevention does not fit the stated orthodontics feature.
