A patient has a white hypocalcification spot on a canine. All of the following are appropriate treatments EXCEPT:
Show answer and explanation
Correct answer: B. Systemic fluoride (ineffective for existing hypocalcification defect)
- A. Topical fluoride varnish can help remineralize superficial hypocalcified enamel and is an appropriate treatment option.
- B. Correct. SYSTEMIC FLUORIDE is ineffective for EXISTING enamel hypocalcification because the enamel has already formed — systemic fluoride only affects developing teeth. It cannot retroactively mineralize an already-formed enamel defect.
- C. Microabrasion (mild acid + pumice) removes superficial hypocalcified enamel and can improve the appearance of white spots.
- D. Resin infiltration (Icon) fills the porous hypocalcified enamel with resin, masking the white spot — a minimally invasive and effective treatment.
