Cents and sensibility
When preparing a root canal, there seems to be nothing that can’t beachieved by a skilled endodontist. In the right hands, virtually anyroot canal can be prepared with virtually any file or number of files.The very small curvature radius and large curvature angle in thefeatured x-ray...  Read More
Is scientific hype replacing scientific evidence?
Many endodontists have devoted a great amount ofvaluable time to endodontic instrumentation research using scientificevidence in an attempt to convey useful information for the advancementof endodontics. Scientific evidence relies on comprehensive data and itis crucial for researchers to ensure...  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 therealization that so much of my time was devoted to compilingconventional, or what could be considered useless, data for evaluatingendodontic files. Someone once commented, “There is no ox so dumb as theorthodox.”For...  Read More
Join Us for a Complimentary Seminar
The Efficient and Productive Endodontic Practice: Dr. JohnT.McSpaddenIf you save a penny and double it every day, it only takes 27 days to become a millionaire. We are familiar with the power of compound returns but sometimes the power of accumulative returns escapes us, particularly in our...  Read More
Direct comparisons of a singular NiTi file design with and without heat treatment
The physical properties of nickel titanium endodontic files that areheat treated for enhancing flexibility differ so widely that definitecorrelations are difficult to determine. This is particularly true whenthere are no controls for heat treated files having the same designdimensions. D&S...  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 thecapabilities of a file. This begs the question: exactly how muchinformation do we get from an x-ray. Dr. HB Johnson, one of the pioneersof endodontics and the man who coined the term endodontics, is theperson that performed the...  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 asnot only an instrument that enlarges a canal but one that acts as anauger as well; it conveys debris. When a file unwinds to the extent thatits helix augers apically rather than...  Read More
Maximizing Efficiency - for what it's worth
Time is the one commodity shared equally with all. No matter who we are or where we are we each get 60 minutes with every hour, 24 hours each and every day and then it is gone forever. One cannot keep time from passing, yet, profoundly, one can save time.Early in my career, I had the good fortune...  Read More

What is the fewest number of endodontic files required for canal instrumentation?
After 35 years of for endo file efficiency vs. file stress, I continue to be puzzled forhow to best answer the frequent question: “How few of your instrumentsare necessary to prepare a canal?” Just as perplexing are the marketingclaims asserting that only 3-5 of their particular files...  Read More

Why different endo files have a different "feel"
The One Endo file's cutting edge extends through its tip allowing it to cut very efficiently. This efficiency, however, may be perceived as having an "aggressive feel".Endodontic files basically have three functions: forming a dentinalchip, dislodging the chip, and transporting...  Read More
