The Effect of Chlorhexidine and Dimethyl Sulfoxide on Long-Term Microleakage of Two Different Sealers in Root Canals
Objective: The aim of root canal obturation is to prevent leakage and inhibit microbial invasion. This study aimed to determine the effect of chlorhexidine (CHX) and dimethyl sulfoxide (DMSO) as final irrigants on microleakage ...
Damage of the Interface Between an Orthodontic Bracket and Enamel – the Effect of Some Elastic Properties of the Adhesive Material
<p>
The aim of this study was to investigate the magnitude of debonding stress of an orthodontic bracket bonded to the enamel with resin systems having different elastic properties. For the same purpose, sixty human ...
Scattering of therapeutic radiation in the presence of craniofacial bone reconstruction materials
<h3>Purpose</h3><p>Radiation scattering from bone reconstruction materials can cause problems from prolonged healing to osteoradionecrosis. Glass fiber reinforced composite (FRC) has been introduced for bone reconstruction ...
Effect of interface surface design on the fracture behavior of bilayered composites
<p>This study aimed to evaluate the effect of different interface designs on the load-bearing capacity of bilayered composite structures (BLS). Cylindrical specimens of BLS were prepared from base composite of 3.5 mm ...
Micro and Nano Structural Analysis of Dental Ceramic and Luting Resin Interface and the Effect of Water Exposure on Integrity of Cement Interface
The current study was aimed to evaluate-by micro and nano-structural analysis-the interface between dental ceramic and resin materials. The degree of resin impregnation into the etched micro patterns, the nano-mechanical ...
Biomaterial and implant induced ossification: in vitro and in vivo findings
Material-induced ossification is suggested as a suitable approach to heal large bone defects. Fiber-reinforced composite-bioactive glasses (FRC-BG) display properties which could enhance the ossification of calvarial ...
Evaluation of intensity of artefacts in CBCT by radio-opacity of composite simulation models of implants in vitro
<p>
Objectives: The aim was to compare the intensity of artefacts in CBCT images caused by different percentages of radio-opacifying material in composite simulation models of implants. Titanium and zirconia models of ...
Effect of solvent/disinfectant ethanol on the micro-surface structure and properties of multiphase denture base polymers
<p>
Conclusion: The present study demonstrated that denture base polymers, especially autopolymerized denture base polymer is prone for surface crazing and dissolving by solvent/disinfectant ethanol. The interphase region ...
Load-bearing capacity of human incisor restored with various fiber-reinforced composite posts
Objectives. The aim of this study was to evaluate the load-bearing capacity and microstrain of incisors restored with posts of various kinds. Both prefabricated titanium posts and different fiber-reinforced composite posts ...
