STUDY REGARDING THE PROFILE OF FINISHED SURFACES OF SOME DIRECT COMPOSITE RESINS

Abstract

The finishing and adequate polishing of composite restorations represent important aspects of the restoration procedures in terms of esthetics and clinical longevity of the restored teeth. The investigations carried out on the surface quality aimed at showing the surface topography corresponding to three composite diacrylic resins having different sizes of the mineral particles for filling whose final finishing by polishing was made mechanically. The surfaces finished by polishing were subjected to imagistic analysis and experimental measurements at nanometric scale by using Nanosurf easyScan 2 AFM atomic force microscopic system. By analyzing the captured images we may affirm that the specimen made of Natural Elegance commercial product - Henry Schein Inc. shows the most uniform surface
