Investigation of an Advanced Material for the Infiltration of White Spot Lesions in Orthodontics

Abstract:

In the Romanian population, during the fixed orthodontic treatment, sometimes appear white spot lesions (WSLs). These are areas of demineralized enamel witch untreated lead to the formation of cavited carious lesions. Until now the therapy of choice for such lesions was fluoridation that proved itself inadequate in terms of aesthetics. The innovative solution of the German Firma DMG (Icon®) proposes the filling and reinforcing of the pore system of a WSL with a light-curable resin (Icon-Infiltrant). The purpose of this study was to assess whether the optical coherence tomography (OCT) can evaluate, in vitro, by en face scans the penetration of this advanced new material into natural enamel caries. We applied the classic therapeutic procedures proposed by the German company. After infiltration of the WSL we observed a deep resin penetration. Clinically there was a significant improvement in the aesthetics of the affected tooth surfaces and their evolution was stopped demonstrating that this technique is effective in the therapy of WSLs at patients with fixed orthodontic therapy. Also OCT proved to be a reliable technique for acquiring images of resin infiltrated WSLs recommending this technology for further fundamental studies in the field.
