Evaluation of UV photofunctionalization effect on ultrastructural properties of SLA titanium disks: An in vitro study.

Background: The success rate of dental implants diminishes over time; the lack of osseointegration and infection are the major causes of most implant failures. One of the effective methods to improve the surface properties is to irradiate ultraviolet (UV) light. This study investigated the effect of UV photofunctionalization on the ultrasuperficial properties of sandblasted, large-grit, acid-etched (SLA) titanium discs.

Study of Cytotoxic and Antibacterial Activity of Ag- and Mg-Dual-Doped ZnO Nanoparticles.

A non-laborious process for the fabrication of silver and magnesium dual doped zinc oxide nanoparticles (Ag/Mg-ZnO NP) is described. The wurtzite ZnO nano-structures and the dual doped NP were analyzed by PXRD. SEM data showed the hexagonal morphology of our product, while the gathered anti-bacterial outcomes towards Streptococcus mutans bacteria through micro-dilution technic affirmed the enhanced performance of doped NP compared to the native ones.

The Evaluation of Debris and Smear Layer Generated by Three Rotary Instruments Neo NiTi, 2Shape and Revo_S: An Scanning Electron Microscopic Study.

Introduction: This study compared the cleaning effectiveness of NeoNiTi, 2Shape and Revo_S rotary instruments.

Materials And Methods: Fifty mandibular molar mesial roots were selected with an angle of curvature less than 20 degrees divided into three groups (=15). Five samples were selected as negative control group.
