Application of Nondestructive Testing in Cyclic Fatigue Evaluation of Endodontic Ni-Ti Rotary Instruments
Nondestructive testing Nickel-titanium Cyclic fatigue
2009/9/14
The purpose of this study was to investigate the application of nondestructive testing in cyclic fatigue evaluation of endodontic ProFile® nickel-titanium (NiTi) rotary instruments. As-received Pr...
Influence of Cyclic Loading on Fiber Post and Composite Resin Core
Fiber post and composite resin core Failure load Cyclic loading
2009/9/11
From a selection of four kinds of post and core systems, including a fiber post and composite resin core, the purpose of this study was to determine the most effective system for the restoration of en...
Influence of lateral-oblique cyclic loading on abutment screw loosening of internal and external hexagon implants
Screw loosening Preload Abutment screw
2009/9/11
To date, there is no evidence that internal anti-rotation configurations are better than external ones. The purpose of this study was to evaluate the effect of eccentric cyclic loading on abutment scr...
Effects of attrition, prior acid-etching, and cyclic loading on the bond strength of a self-etching adhesive system to dentin
Attrition Self-etching adhesive system Microtensile bond strength
2009/9/11
The purpose of this study was to evaluate the effects of dentin attrition, phosphoric acid etching, and cyclic loading on the microtensile bond strength (μTBS) of a self-etching adhesive system to den...
Effect of loading weight on bond durability of composite — type resin cement under cyclic impact test (part 2).Loading with light weight of 100–120 g
Cyclic impact load Adhesive resin cement Bond durability
2009/9/11
The bond durability of composite-type resin cement was evaluated by means of cyclic impact tests using three different loads. In terms of experimental setup, a casting alloy, 12%Au-Pd-Ag, was used as ...
Effects of Cyclic Tension Force on Differentiation in Human Periodontal Ligament Cells
mechanical stress differentiation human periodontal ligament (HPDL) cell periostin Twist
2009/5/20
The periodontal ligament is exposed to mechanical stress such as occlusion, so periodontal ligament cells may have defenses against mechanical stress. We searched for the influence of mechanical stres...
