Can different polymerization times affect the surface microhardness, water sorption, and water solubility of flowable composite resins?

Kazak, Mağrur; Köymen, Safiye Selin; Dönmez, Nazmiye (University Federal de Uberlandia, 2023)

This in vitro study evaluated and compared the effects of different polymerization times on the surface microhardness, water sorption, and water solubility of flowable composite resins. Three flowable composite resins [Es ...
Depth of cure, mechanical properties and morphology of dual-cure bulk-fill composites

Sarıalioğlu Güngör, Ayça; Durmuş, Ali; Zengin Kurt, Belma; Köymen, Safiye Selin; Dönmez, Nazmiye (Universidad de Costa Rica, 2023)

This study evaluated selected structural and physical properties, such as degree of conversion (DC), Vickers hardness (VHN), and compression strength (CS), of three new dual-cure bulk-fill resin-based composites (RBCs; ...
Investigating the cytotoxicity of dual-cure bulk-fill resin materials on L929 cells

Köymen, Safiye Selin; Dönmez, Nazmiye; Yenigün, Vildan Betül; Bahadori, Fatemeh; Koçyiğit, Abdurrahim (MDPI, 2022)

The aim of this in vitro study was to investigate cytotoxic effects of dual-cure bulk-fill resin materials polymerized with a third-generation LED light-curing unit (LCU) on L929 fibroblast cells in terms of morphology and ...
