June 14-20, 2010United Kingdom Edition Flexibility is our Strength D MG (Dental Material Gesellschaft mbH), from Hamburg in Germany organised an international sci- entific symposium on micro- invasive caries management. The event took place in Ham- burg, April 15-16, 2010. A group of 20 researchers and key opin- ion leaders from all over the world were invited to take part, share their opinions and discuss further projects. Presentations about clini- cal studies and in-vitro projects were given by: PD Dr Hendrik Meyer-Lückel and Dr Sebas- tian Paris (Kiel, Germany), Dr Marcio Garcia dos Santos (São Paulo, Brazil), Dr David Manton and Dr Joseph Palamara (Mel- bourne, Australia), Dr Hervé Tassery (Marseille, France), Dr Suchit Poolthong (Bangkok, Thailand, Dr Ferranti Wong (London, UK), Dr Chris Deery (Sheffield, UK), Dr Lyndie Fos- ter-Page (Dunedin, New Zea- land) and Dr Oksana Denga (Odessa, Ukraine). Based on the current paradigms and scien- tific knowledge, new develop- ments in caries management on all intervention levels were discussed, with a particular focus on micro-invasive caries management. Over the last 10 years the caries infiltration approach was developed and researched at the Charité University of Berlin and the University of Kiel by Dr Hen- drik Meyer-Lückel and Dr Se- bastian Paris. Upon having clin- ical evidence of the efficacy and reaching clinical applicability of the new technique, a product for daily practice was launched in 2009 in cooperation with DMG, Hamburg, Germany as their industrial partner. Caries infiltration with Icon® (DMG, Hamburg, Germany) is a novel micro-invasive treatment pro- cedure closing the gap between non-invasive and minimally in- vasive treatment options, aim- ing to preserve as much healthy tooth structure as possible and thus offering a possibility to treat early non-cavitated lesions without drilling. It is an easy to follow three-step-clinical proce- dure to treat lesions on proximal and vestibular surfaces in both, the primary and permanent den- tition. The basic principle is to seal early caries with a specially designed low viscous resin ma- terial that penetrates into the porous structure of the lesion by means of capillary forces using the remaining structures in the lesion as a scaffold. The pore volume of the lesion is made ac- cessible removing the pseudo- intact surface layer using a 15 per cent HCl etching gel (Icon® Etch) for two minutes. After this period, the remaining water in the lesion is removed using 99 per cent ethanol (Icon® Dry). Subsequently, within a three minutes application time, the in- filtrating resin (Icon® Infiltrant) penetrates the caries up to sev- eral hundred micrometers. The ability to penetrate into the pore system of the lesion is driven by capillary forces and determined by the physical and chemical properties of the infiltrant.
