Effect of the of Zeolite Containing Silver-Zinc Nanoparticles on the Push out Bond Strength of Mineral Trioxide Aggregate in Simulated Furcation Perforation.

Statement Of The Problem: Recently, zeolite has been regarded to improve the properties of dental materials such as mineral trioxide aggregate (MTA).

Purpose: The aim of the present study was to evaluate the effect of incorporating zeolite/silver/zinc (Ze/Ag/Zn) composite at 2 wt% to MTA powder on the push-out bond strength in simulated furcation perforations.

Materials And Method: Furcal perforations, measuring 1.

Evaluation of the effect of low level laser therapy toothbrush in treatment of dentin hypersensitivity.

Introduction: Dentin hypersensitivity is one of the most common complications that affect patients after periodontal therapy. Recently low level laser therapy has been introduced as a new treatment modality and has produced beneficial results. The purpose of this study is to evaluate the effect of low level laser therapy toothbrushes in reduction of dentin hypersensitivity.
