STUDY: Cyclic Fatigue Resistance of WaveOne Gold, ProDesign R and ProDesign Logic Files in Curved Canals In Vitro
Note:
The study refers to Bassi Logic as it’s trade name in Brazil, ProDesign Logic and ProDesign R. It is abbriviated in the article as PDL and PDR respectively.
Summary
About the Study:
This study evaluated the cyclic fatigue resistance of Bassi Logic files compared with Wave One Gold.
Highlights from the study:
“In this study, ProDesign Logic [Bassi Logic] instrumented all canals without fractures.”
“The cyclic fatigue resistance of ProDesign R [Bassi Logic Retreatment] and ProDesign Logic [Bassi Logic] instruments was superior to WaveOne Gold.”
The use of continuous rotational motion in canals with a glide path provided the ProDesign Logic [Bassi Logic] instrument shorter instrumentation time.
