    Background: Novel dental materials have created the need for new knowledge, in terms of abrasion both in a quantitative, i.e. how much of the surface that has been abraded as well as in a qualitative way, i.e. the roughness of the surface after brushing. Furthermore, the development of new measuring techniques has created a new interest in this type of research. Objective: To investigate if and how, different filling-materials and an acrylic are affected by brushing with and without tooth pastes. Methods: The following dental materials were used: a cold cured acrylic, a flow composite and three different hybrid composites. The specimens were attached to acrylic plates and were exposed to brushing in a brushing machine using water alone and two different toothpastes: a low abrasive .. View More»
