Background: A novel technique of sterilization of endodontic files is introduced in this article.
Aims: Newly introduced sterilization unit, named "SteriFast" is compared with autoclave and glass bead sterilizer using biological indicator.
Materials And Methods: Spore strips of were cultured in nutrient broth.
Aim: The aim of this study is to evaluate the effect of alcohol and nonalcohol containing mouth rinses on the color stability of a nanofilled resin composite restorative material.
Materials And Methods: A total of 120 samples of a nanofilled resin composite material (Tetric N-Ceram, Ivoclar Vivadent AG, FL-9494 Schaan/Liechtenstein) were prepared and immersed in distilled water for 24 h. Baseline color values were recorded using Color Spectrophotometer 3600d (Konica Minolta, Japan).
Introduction: The objective of this study was to evaluate dentinal defects formed by new rotary system - Protaper next™ (PTN).
Materials And Methods: Sixty single-rooted premolars were selected. All specimens were decoronated and divided into four groups, each group having 15 specimens.
