Biocalex / Endocal

What exactly is it ?????


Note: I DO NOT like Biocalex and will never use it again, but the following is general information about it to help you understand what it is, why some dentists use it, and why I will not use it again with my patients.


Biocalex/Endocal is a  root canal medication/filler that uses  Calcium Oxide in  ethyl glycol (ethyl glycol...sound familiar? as in antifreeze and toxic???).  The calcium oxide   combines with water in the tooth and becomes calcium hydroxide which is a well-known and long used and documented excellent root canal material.  It then goes on to  combine with carbon dioxide [CO2] and become essentially Plaster of Paris.

Biocalex  (recently marketed under the new name Endocal) is a system and set of materials  used for  root canal treatment.  Many  "holistic" or "alternative" dentists have long held the  view that root canals are "bad" and should be avoided. They believe that   teeth that have had root canal treatment should best be extracted.

Their views stem mainly from the turn of the century (early 1900's) publications of Dr. Weston Price, in which  he makes startling conclusions from his own research suggesting that infection from root canal teeth can and does cause serious infections  in remote parts of the body.  There is probably some  merit to his claims, but in this author's opinion, his claims are incredibly overstated and, in fact, suspect!   The fact that nobody else has been able to reproduce his findings further pushes me to  that opinion.  For much  more detail about the work of Dr. Price and the controversies resulting from that work, please read my other  articles in the Root Canal section listed on the Topics page.  That  should give you  all the info you  want...perhaps more!

Anyway... while holistic dentists seem to  be almost unanimous about  NO ROOT CANALS...

they have sometimes become convinced that  if the root canal is done using either a Laser or using  Biocalex,  that somehow it's ok. 

There's an article on Laser root canals on this site, too, if you want to know  more about that.


As far as Biocalex goes, I have stated on this  website that  there are several problems with it and that  I will no longer use it (I only used it on about  6 patients and that was enough for me...).  Several years ago, I believe there was more info on Biocalex on the internet but now there isn't much at all.  Most of the research  was written and published in French. I can't read French....Those problems included:

  1. Teeth being split by the Biocalex (while they deny that, of course,  read the comments  in THEIR literature).

  2. Pain and  strange discomfort after using Biocalex (not denied)

  3. The Biocalex becomes invisible in the tooth  making later diagnosis nearly impossible (not denied)

  4. Biocalex becomes very hard inside the canals, making re-treatment difficult or impossible if needed later (not denied)

Many of you have asked about  documentation regarding the "problems I have talked about "  with  Biocalex / Endocal. So, I looked through  the literature I have  collected on  hand and what I think is  most instructive is to show you  the info that was supplied to me from the manufacturer and distributor or Biocalex (now called Endocal, I believe).

Keep in  mind this is THEIR own literature so it's as friendly and supportive  as possible toward their own product.   You'll see I have interjected some comments (in RED) to point out my interpretation of some of their remarks.  I will also include other references if I find any that  I think are instructive.


These sheets were  from the manufacturer and distributor of  Biocalex....

I sincerely apologize for the poor quality of the print, making it difficult to read,  but I didn't want to re-type the whole thing and also I wanted to show a copy of the actual literature that  came with the Biocalex from the manufacturer.

This reference deals with research showing that Biocalex splits teeth. In fact it refers to research that shows that TWENTY PERCENT of the teeth in the study split after the use of Biocalex / Endocal



Just keep in mind that  the info on this  page is  put out by the makers and sellers of Biocalex and they are trying to make it look as  good as they can !

Bottom line:.....(in my opinion)
The  real active  part of the Biocalex technique is, in my opinion, calcium hydroxide, and there are ways to use calcium hydroxide without antifreeze and without  calcium oxide and without it  disappearing and turning into plaster, possibly splitting teeth, and only rarely if ever  causing pain, so to me it's a no-brainer.  For  more info on that, see  the other  root canal articles on this site about calcium hydroxide.


Please note:     You will also find several WebPages on the internet that say Biocalex is the best thing around.  So, read as much as you can and make your own decisions. I have tried to tell it how I see it, but obviously that's just my point of view.  Others have differing views.  In the end, it's up to you..... it's your body, and your tooth...and your money.


I hope this brief discussion has been helpful and informative.  Good luck!

Holism in dentistry is an approach to dental treatment, primarily  caring for  patients' health and safety from both a conventional as well as  "alternative healthcare" point of view.   It is sometimes called "biological" dentistry or "biocompatible" dentistry.  In it's fullest sense, I believe it   acknowledges and deals with  the mind, body and spirit of the patient, not just his or her "teeth".  See Topics / Info.....

Cosmetic dentistry is about doing   quality , esthetic dentistry in a way that looks natural to begin with, and furthermore,   can even  improve  one's  attractiveness through techniques such as bonding, bleaching, veneers, caps, implants and more.  It can   be like "instant orthodontics" in correcting  crooked, twisted or misplaced teeth in many instances.  Dark or misshapen teeth can be restored.   Smiles that lack youthful vigor or beauty can be revitalized! See Topics / Info..

Bleaching, veneers, bonding, caps, bridges, and implants  are cosmetic dentistry treatments that are also  discussed in  Cosmetic Dentistry, and more...
