Dentists are regularly faced within their profession with patients who have white discoloration on their front teeth. This is often experienced aesthetically disturbing by patients making treatment desired. Recently a new treatment called ICON (ICON, DMG, Hamburg, Duitsland) was introduced. The advantage of this method is the non-invasive camouflaging character. The camouflage-effectiveness might be improved if the relative depth of penetration of ICON-infiltrate (ICON-infiltrant, DMG, Hamburg, Duitsland) is increased. This research examined if a longer etching time had an influence on the relative penetration depths. The hypothesis was that the infiltrated white spot lesions would have a greater relative infiltration depth after a longer etching time. An in- vitro study was performed on 40 extracted teeth and divided into 4 groups: 1 x 2 (group 1), 2 x 2 (group 2), 3 x 2 (group 3), 4 x 2 (group 4). Afterwards the ICON-protocol was applied, subsequently, the elements were sliced and measured under the fluorescence microscope. The maximum relative infiltration depths were analysed with the Kruskal-Wallis Rank Sum test. The result showed a significant difference in relative infiltration depths between the groups. The post-hoc Dunn test with Holm correction showed a significant bigger relative infiltration of ICON in the group of 4 x 2 minute etching comparing the group of 2 x 2 minute etching. No significant difference was found between the other groups. Within the limitations of this in-vitro study, it was concluded that a longer etch time might lead to a greater depth of infiltration.
