Biocompatibility of composite resins

open access: yesDental Research Journal, 2011
Dental materials that are used in dentistry should be harmless to oral tissues, so they should not contain any leachable toxic and diffusible substances that can cause some side effects.

Erosion of Composite Resins [PDF]

open access: yesJournal 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.

Processing of Functional Composite Resins Using Deep Eutectic Solvent

open access: yesCrystals, 2020
Deep eutectic solvents (DESs)—a promising class of alternatives to conventional ionic liquids (ILs) that have freezing points lower than the individual components—are typically formed from two or more components through hydrogen bond interactions. Due to
