[ 1 ] - Effect of UV-Photofunctionalization on Bioactivity of Titanium to Promote Human Mesenchymal Stem Cells
Background and Aim: The present study introduces photofunctionalization as a technique for tackling biological aging and increasing the bioactivity of titanium. This in-vitro study evaluated the effects of ultraviolet (UVC) light treatment of titanium surfaces with different time-related changes on the behavior and function of human mesenchymal stem cells (MSCs). Materials and Methods: MSCs we...
[ 2 ] - In-Vitro Comparative Study of the Effect of Four Finishing and Polishing Tools on Surface Roughness of a Microhybrid Resin Composite
Background and Aim: The complications of unwanted surface roughness of composite restorations are highly common due to the increasing use of this restorative material. Therefore, the present study was designed to compare the effect of four finishing and polishing (F&P) tools on surface roughness of microhybrid resin composites. Materials and Methods: This experimental study was performed on 42...
[ 3 ] - Bacterial Accumulation on Triclosan-Coated and Silk Sutures After Dental Implant Surgery
Background and Aim: The risk of surgical site infection may depend on bacterial attachment and physical and chemical properties of suture materials. This study aimed to evaluate bacterial accumulation on triclosan-coated (Vicryl Plus) and silk sutures placed at different distances from Vicryl Plus after dental implant surgery. Materials and Methods: In this randomized controlled trial, 20 pati...
[ 4 ] - Evaluation of the Effect of Zirconia and Titanium Abutments on Microleakage of Implant-Abutment Interface Under Oblique Cyclic Loading In Vitro
Background and Aim: Oral bacteria can proliferate in the implant-abutment interface (IAI) and cause inflammation in the peri-implant tissues and adjacent bone. This study aimed to assess the effect of zirconia and titanium abutments on the microleakage of the IAI under oblique cyclic loading conditions. Materials and Methods: In this in-vitro study, 12 implant-abutment assemblies with zirconia...
