Endo for GP's stopped publication within a few months after they decided they could do without Dr. Weathers as editor. At the time they left over 3600 subscribers hanging.
If you were one of those who got, well how should we say it, reamed, filed and backfilled, the original author is still going strong as 'Practical Endodontics'. He publishes eight pages of invaluable info about ten times per year.
Latest word is that it has ceased to exist as a regular publication and is published as a sporadic newsletter when new information has become available, mostly about the techniques taught in the "Root Camp" courses given in Griffin, GA.
