OBJECTIVE Re-examining the well accepted concept that Zinc-Oxide-Eugenol bases (ZOE) have a negative effect on composite restoration materials microhardness, in light of the advancement in composite materials and newer publications. METHODS Five modern composite restoration materials were used, including hybrid (Xtra-fill and Z250), micro-fill hybrid (G-aenial and Gradia-direct) and methacryl...

In order to evaluate the healing effect of eugenol and other nanofibers, 100 male Wistar rats (200±10 g) were used with 14-15 weeks of age in this study. All of the male rats were transferred in the standard cages under controlled exposure conditions in a 12:12 h light/dark cycle with a constant temperature about 22±2 oC. In addition, the male rats were fed with pellets. Firstly, ane...
