Assessment of a New Resin-based Composite Filling Material

Evaluation of a new resin-based composite material. Amalgam and composite are the most commonly used restorative materials in dentistry. Due to the toxicity of mercury and the subsequent environmental problems, the search for alternatives continues and search into new composite restorative materials intensifies. The presently available composites have improved, but shrinkage of the composite during the curing procedure is still a clinical problem. A new composite restorative material has among other advantages demonstrated lower shrinkage in laboratory studies, due to a new formulation of the material. This project aims to study the clinical performance of this new composite compared to a commonly used composite restoration material. 72 patients (158 teeth) are allocated to the project which is carried out at the School of dentistry, University of Aarhus, Denmark.
