All of the following can improve the appearance of enamel hypocalcification EXCEPT:
Show answer and explanation
Correct answer: A. Air abrasion
- A. Correct. Air abrasion removes sound tooth structure without addressing the optical difference of the subsurface porous lesion, and it can enlarge the defect. It is not an appropriate management for white spot lesions.
- B. Resin infiltration fills the porous subsurface lesion, matching its refractive index to enamel and visually masking the white spot.
- C. CPP-ACP promotes subsurface remineralization and reduces lesion visibility.
- D. Microabrasion is a recognized conservative technique for superficial enamel discoloration.
