Ausmaß und Beständigkeit der ästhetischen Verbesserung von Multibrackettherapie-induzierten White-Spot-Läsionen nach Icon-Infiltration -eine prospektive, randomisierte, splitmouth-kontrollierte klinische Studie

TL;DRAbstract

INTRODUCTION: White spot lesions that form during orthodontic treatment are a problem for patients and clinicians. Lesion infiltration with low-viscosity light-cured resin has been proposed as a treatment to inhibit further demineralization. The purpose of this study was to assess the durability of assimilation of white spot lesions and sound adjacent enamel achieved over 6 months with resin infiltration. METHODS: Twenty-one consecutive subjects with 231 noncavitated, unrestored white spot lesions after multibracket treatment were recruited at the Department of Orthodontics, University of Göttingen (Germany), for lesion infiltration. A simple randomized, split-mouth, controlled design was used to allocate subjects to the treatment and control groups. In the treatment group, white spot lesion infiltration of the anterior teeth was performed with low-viscosity light-cured resin after enamel conditioning with a 15% HCl gel. Color and lightness of the white spot lesions and the sound adjac
