Question 203 · LDEK · Diagnosis
The efficacy of remineralization of a subsurface cavity (white spot lesion) is denoted by:
1) no progression, e.g. no evolution into a cavity;
2) shining surface of the spot;
3) rough, white frosted surface of the spot;
4) “cicatrization of tissue” seen under microscope;
5) microscopically seen full recovering of the hard tissue, i.e. total remineralization.
The correct answer is:
2) shining surface of the spot;
3) rough, white frosted surface of the spot;
4) “cicatrization of tissue” seen under microscope;
5) microscopically seen full recovering of the hard tissue, i.e. total remineralization.
The correct answer is:
- A. 1,2,4.
- B. 1,3.
- C. 1,5.
- D. 1,3,4.
- E. 1,2,5.
Hint
Compare the clinical appearance of active and arrested white spots and what microscopy shows after remineralization.
