Cents and sensibility
When preparing a root canal, there seems to be nothing that can’t be achieved by a skilled endodontist. In the right hands, virtually any root canal can be prepared with virtually any file or number of files. The very small curvature radius and large curvature angle in the featured x-ray...Read More

Limiting Torsional Stress on Endodontic Files: Lubrication, Irrigation and/or Technique
I was recently asked if irrigation and lubrication influenced the stresses a file undergoes during instrumentation. Research that I carried out indicated irrigation and lubrication can reduce torque requirements by as much as 400% compared to rotating in a dry canal. However, one can see from the...Read More

Conventional Research: Greater Value than Actuality?
After so many years of research, it is daunting to succumb to the realization that so much of my time was devoted to compiling conventional, or what could be considered useless, data for evaluating endodontic files. Someone once commented, “There is no ox so dumb as...Read More

Direct comparisons of a singular NiTi file design with and without heat treatment
The physical properties of nickel titanium endodontic files that are heat treated for enhancing flexibility differ so widely that definite correlations are difficult to determine. This is particularly true when there are no controls for heat treated files having the same design dimensions....Read More

If a picture is worth a thousand words, then what's that worth?
Most of the time x-rays of tortuous canals are used to demonstrate the capabilities of a file. This begs the question: exactly how much information do we get from an x-ray. Dr. HB Johnson, one of the pioneers of endodontics and the man who coined the term endodontics, is the person that...Read More

What difference does unwinding an endodontic file make if it doesn’t break?
I was recently asked why would it matter if an unwound as long as it didn’t break. First, let us think of a file as not only an instrument that enlarges a canal but one that acts as an auger as well; it conveys debris. When a file unwinds to the extent that its helix augers...Read More
