Evaluation of Optical Properties of Different Restorative Composite Resins
Revista da Faculdade de Odontologia de Porto Alegre, 2008 The esthetic demands of patients have encouraged the search for restorative materials increasingly similar to natural teeth. This requires knowledge on the optical properties of dental structures and restorative materials.

Erosion of Composite Resins [PDF]
Journal of Dental Research, 1980 The surface degradation of composite resins caused by accelerated aging was studied. Accelerated aging for 900 hours caused erosion of the resin matrices and exposure of filler particles. Differences in surface profiles after aging suggest that the materials eroded at different rates. Accelerated aging may model erosive wear of composites.

Journal of the Formosan Medical Association, 2014 Polymerization shrinkage is one of the main causes of dental restoration failure. This study tried to conjugate two diisocyanate side chains to dimethacrylate resins in order to reduce polymerization shrinkage and increase the hardness of composite ...
