Figure 5

Examples of results of enamel thickness measurement for the subsequent stages of tooth treatment. It shows: a) enamel thickness before any interference L _da (n,i), b) after polishing with paste L _db (n,i), c) after etching L _dc (n,i), d) after application of the adhesive system L _dd (n,i), e) an orthodontic bracket L _de (n,i), f) after bracket removal L _df (n,i), g) after cleaning off adhesive residue L _dg (n,i). These images then form the basis for the analysis of the impact of treatment methods and choice of orthodontic systems on changes in enamel thickness. The thickness is expressed in pixels for the artificial colour palette (ranges from blue to red, and passes through the colours cyan, yellow, and orange).
