During the one and two years follow up, ICDAS scores of most of the tooth surfaces were stable and only improved tooth surfaces were in a minority.
Form baseline to one year; stable: 2658(91.2%), improved 107 (3.7%), and progressed 148(5.1%).
From baseline to two years; stable: 2644 (91.2%), improved 111 (3.8%), and progressed 158(5.4%).
For the calculation, unerupted teeth at baseline were excluded.
