Introduction: D-galactose (D-gal) is well known as an appropriate agent to induced aging effects in the in vivo and in vitro models. In the present study, we selected crocin, the main constituent of Crocus sativus L. (Saffron), against D-gal cytotoxicity in human neuroblastoma SH-SY5Y cells. Materials and Methods:  Cells were pretreated with crocin (25-500 µM) for 24 h and then expos...

Soft denture-lining materials are an important treatment option for patients who have chronic soreness associated with dental prostheses. Three distinctly different types of materials are generally used. These are plasticized polymers or copolymers, silicones, or polyphosphazene fluoroelastomer. The acceptance of these materials by patients and dentists is variable. The objective of this study ...

introduction: discoloration of dental composite resins is one of the most common reasons for replacement of these restorations. this in vitro study was carried out to evaluate the effect of aging on discoloration of silorane-based filtek p90 and micro-hybrid z250 composite resins. materials and methods:   this experimental study was carried out on 10 disk-shaped filtek p90 and z250 samples, mea...

PURPOSE The purpose of this study was to investigate the effect of different plasticizing aging solutions on wear resistance and hardness of selected universal resin-based dental composites. METHODS Three light cured (one nanofilled, two microhybride) and one hybride chemical cured composites were aged at 37 °C for 48 h in distillated water, ethyl alcohol solution or Listerine mouthwash. Afte...
