Atomic Force Microscopy study for assessing the characteristics of news materials sealants

Catalina Iulia Saveanu, Oana Dragos

Abstract :

The degree of finishing for a surface depends on the structural features of the materials used. We proposed the comparative assessment "in vitro" of the topography and roughness for 4 sealing resin composite materials. The materials used were: Fissurit® FX (VOCO, Germany), DEFENSE CHROMA (ANGELUS®, Brasil), WAVE (SDI, Australia), PermaFlow™ (Ultradent, USA). Topography and roughness were analyzed by Atomic Force Microscopy (Park SYSTEMS XE –100) for a 5μm × 5μm with scan rate of 0.5 Hz and a resolution of 256 × 256 pixels. Tridimensional topographic analysis was performed by analysis software (XEI – Image–Processing and Analysis). Surface roughness was measured for each material in nanometers. There were differences in surface roughness among the sealants but their values were significantly different in favor of PermaFlow™ (Ultradent, USA).
