How the Facts Are Suppressed in Connection with Bone Meal

By Alfred Aslander

Summary: In this circular from the Division of Agriculture, Royal Institute of Technology, Stockholm, Sweden, the author surveys research conducted in Sweden and Switzerland on supplementing the diet with bone meal to prevent dental caries (cavities). He exposes significant design flaws in a study cited by the dental establishment to discredit bone-meal supplementation, and he describes a number of other studies that showed bone meal to be highly effective in preventing tooth decay. He also recounts his thwarted effort to have his own research published by journals beholden to the dental establishment. “At least once upon a time it was considered as an axiom that scientific investigations should aim solely at the pursuit of the truth, and consequently scientific journals should aim at publishing the truth. In this case it seems…[their] aim has been something else.” Note: a year before this article appeared, Dr. Royal Lee introduced a completely raw, cold-processed veal bone meal powder (flour) for use by dentists.

How the Facts Are Suppressed in Connection with Bone Meal

Cohen (1963), apparently as an executive for the FDI [World Dental Federation], states that experiments consistently have failed to demonstrate caries-preventive properties in bone meal. This statement is not true. It is founded on results of experiments that have had nothing to do with the true bone meal method as it has been worked out by the writer (Aslander, 1948, 1958, 1960, 1963). Thus it seems called for to elucidate the problem of caries prevention by a proper tooth nutrition.

The bone meal method as a sure caries prophylaxis is the practical application of the writer’s theory of complete tooth nutrition. [This theory is presented] in the manuscript of this article, which was sent, with the exception of the appendix, to the editor of The Journal of the Dental Association of South Africa, Dr. L.C. Abrahams, Salt River, C.P. However, the manuscript was returned with the explanation that the article could not be printed in the journal.

The manuscript was then sent to the editor of the International Dental Journal, Professor H.H. Stones, Liverpool, because the FDI (see appendix) appears to be behind the attack on the bone meal method. Professor Stones replied that the executive committee of the journal’s editorial board had considered the manuscript but declined to publish it in the journal.

The writer is unable to understand this attitude. Once upon a time, at least, it was considered an axiom that scientific investigations should aim solely at the pursuit of the truth, and consequently scientific journals should aim at publishing the truth. In this case it seems to the writer that the aim has been something else. The reader may judge for himself!

In order to be able to discuss the bone meal method, it is necessary to point out the main features of the nutritional theory. They are as follows. A tooth is a living tissue, not a dead mineral structure. Also, a tooth is an independent individual, which grows out of the mandible in somewhat the same way that a plant grows out of the soil. A plant receives nutrients from the soil solution, the tooth from the bloodstream. The same nutritional laws apply to both.

According to well-known physiological laws, any living and growing individual needs a complete set of nutrients in order to attain a normal development. If one or more of the essential nutrients are lacking or present in too small quantities, then severe deficiency diseases will arise. Such deficiency diseases have been found in agricultural plants, in farm animals, and in human beings. They have been studied—and prevented when the deficient nutrition has been corrected.

Growing healthy teeth is very like growing healthy plants. In both cases a complete set of nutrients is necessary. If a tooth receives a deficient nutrition during the period of growth, then deficiency diseases are bound to appear. The structure of the teeth will be of such poor quality that the tooth cannot withstand the attacks of cariogenic agents; the structure will collapse, and dental caries sets in.

If, on the other hand, a tooth develops under proper nutritional conditions, it will become highly resistant to or immune from dental caries. According to this theory of complete tooth nutrition, the essential tooth nutrients are, in the first place, the minerals that form the tooth structure and the agents that catalyze the formation of the structure (Aslander, 1958).

The writer’s bone meal method was worked out on the assumption that the most conspicuous fault of our common daily fare is its deficiency in tooth-forming minerals. In order to supply a complete tooth nutrition, bone meal was chosen as a food supplement; analyses of the improved brand of bone meal used by the writer (Aslander, 1960) have shown that it contains all the tooth nutrients that up to date have been proved to be essential. In addition, bone meal contains a number of [other] minerals that may in the future be found to be tooth nutrients.

The main rules for the bone meal method are as follows:

  1. Tooth nutrition by bone meal [supplementation] should begin as soon as possible, preferably with the pregnant mother, at least during the second half of the pregnancy and during the months of breast-feeding. The daily dose should be 2 to 3 grams. (It is advisable to begin with small doses.)
  2. Bone meal should be given to the child as soon as the milk is supplemented by other foods. The initial dose should be almost microscopic; by allowing a slow increase, the daily dose should be about 1.5 to 2 grams at the age of two.
  3. The daily dose of about 2 grams must be given continuously until all the teeth are full grown—that is, up to the age of twenty—and thereafter, preferably throughout life.
  4. An improved brand of bone meal must be used. So far, only the brand used by the writer has given perfect results.
  5. Dental care must be natural. If brushing is performed, then only a very soft brush should be allowed. A hard toothbrush and toothpastes must be avoided.

This gentle dental care is based on the theory that the dental plaque is a protective structure that should not be destroyed. The theory introduced by Stratfors (1950), to the effect that the dental plaque is harmful to the teeth because it harbors acid-forming bacteria, must be regarded as somewhat fantastic. It is hardly likely that nature would form a harmful coating on the teeth. Far more probable is the theory that the dental plaque is a protective structure. Dental care should be gentle and aim only at removing food residues that will putrefy and thus produce foul breath.

When the rules above have been strictly observed, it has been proved by more than twenty years of experience that both the deciduous teeth and the permanent teeth will be completely free of dental caries. Thus the main feature of the bone meal method is that it applies to growing teeth, not to full-grown teeth.

Cohen (1963) supports his criticism of the bone meal method with the results obtained in an experiment at Falkenberg, Sweden, (Hal, Lind, and Nystram, 1962) in which 200 schoolchildren were used as guinea pigs. This experiment had the following features:

  1. It started with children at ages of nine to twelve. Thus the experiment started nine to twelve years too late.
  2. The experiment lasted for two school years, with a summer holiday of three months between. Thus the duration of the experiment was negligible.
  3. The daily dose of bone meal—given in crispbread—was only half the normal dose.
  4. The bone meal used was of an unknown quality, not the brand that has given good results.
  5. The degree of dental care is not reported. Probably vigorous brushing with toothpaste was recommended.

If we compare the rules for this experiment at Falkenberg, Sweden, with the rules for the true bone meal method, we find that all the rules governing the true bone meal method have been violated.

It was claimed that the results of the experiment showed that caries activity was not affected. This result is logical. It could have been predicted before the experiment started. The bone meal method must start before the period of tooth formation, not on full-grown teeth. If the deciduous teeth are to be saved, then tooth nutrition must start before or very soon after birth. If the permanent teeth are to grow free of caries, then one must begin at the age of two in order to ensure complete tooth nutrition.

An experiment with children has also been reported from Switzerland (Berner et al., 1959). In this experiment children, in groups of five hundred, were given: a) bone meal tablets b) fluorine tablets, and c) nothing. The experiment started with children five to seven years of age and lasted for three years. The results were as follows: Bone meal reduced dental caries frequency significantly; fluorine tablets were somewhat more protective than bone meal. The results are easily explained.

In this experiment the bone meal gave better results than in the experiment at Falkenberg because it started with younger children and at a period of some active dental growth. Had the experiment started still earlier, say, at the age of two, the permanent teeth of the children would probably have been caries resistant. The action on the deciduous teeth would probably have been negligible at such a late start. That the fluorine tablets gave a better result than the bone meal is also easily explained.

We have here no (or only very little) nutritional action of bone meal and fluorine. We have surface action on more or less full-grown teeth. It is a well-known fact that fluorine, which exerts surface action on the teeth, will to some extent protect the teeth against dental caries. In the fluorine tablet, the fluorine is soluble in water and thus suitable for surface action. In bone meal the fluorine is not soluble in water, which means that bone meal has no (or only very slight) surface activity.

Bone meal contains tooth nutrients that, through the digestive process and via the bloodstream, will reach the teeth and in growing teeth will build up the tooth structure from the core to the surface in such a way that the teeth will be highly resistant to or immune against dental caries. In this way bone meal gives perfect teeth, while fluorine gives only very limited protection against dental caries.

Cohen (1963) also supports his statement with some research reported by Ericsson (1963). However, this paper deals only with the surface action on full-grown teeth by a number of minerals and thus has nothing to do with the bone meal method, which applies only to growing teeth. The distinction between surface action and nutritional action must not be confused.

If we compare the true bone meal method with the experiments at Falkenberg and in Switzerland, it is evident that Cohen (1963) and Leatherman (1963) base their criticism of the bone meal method on results obtained in experiments that have nothing to do with the true bone meal method, which has given very good results, that is to say, 100-percent caries-free teeth.

(At the time of proofreading [this article], a new incident had occurred. In Zahnarztliche Mitteilungen, No. 19, p. 857, 1963, there appears an article by K. Kimmel with the title “Interesante A spekte dermodernen Zahnheilkunde.” In the article it is stated that the bone meal method has failed, just as Cohen and Leatherman have stated. In order to explain the reason for that misstatement, the writer wrote a short article and sent it to the journal, but the editor, Dr. K.M. Hartlemaier, returned the manuscript with the explanation that it could not be printed in the journal. Why this dread of the truth?)

Appendix

Many readers of this article will be unable to find the paragraph in the Newsletter of Federation Dentaire Internationale [FDI, aka the World Dental Federation] attacking the bone meal method that seems to be the foundation of the letter by Cohen (1963) in the Journal of the Dental Association of South Africa. The same may apply to the article by Cohen. For that reason both the paragraph and the article by Cohen are reprinted below.

[Excerpt from Newsletter of Federation Dentaire Internationale, No. 43, p. 1, July 1963:]

Bone Meal as a Caries Preventive

The Commission on Dental Research, in response to a request from the Dental Association of South Africa, recently conducted a survey of current research into the use of bone meal for the prevention of dental caries. After studying the replies received from commission members and other authorities consulted, the commission is of the opinion that there are no major investigations in this field at present time and expert opinion does not favor repetition of experiments that have consistently failed to show caries-preventive properties for humans.

(Writer’s note: This paragraph seems to have been reprinted in a number of dental journals around the world. The writer would be grateful if those journals would also print a paragraph explaining the misleading conclusions drawn by the Commission on Dental Research.)

[Excerpt from the Journal of the Dental Association of South Africa, Vol. 18, No. 9, p. 450, September 15, 1963:]

Bone Meal in Relation to Caries

Stemming from a resolution taken at the 1962 Session of  Federal Council, it was decided to seek information from the Federation of Dentaire Internationale as to whether bone meal plays a part in reducing the incidence of dental caries. A letter with the above title, addressed to the Secretary of the DASA [Dental Association of South Africa], is here reproduced. It puts the matter very clearly. The association is grateful to the FDI for the valuable assistance it has rendered — Editor.

[Letter:]

I have now collated the replies received by this Commission [of Dental Research] in response to your request for information on the above subject. So far as we have been able to ascertain, there is not a great deal of work being carried out in this field at the present time; this is not surprising in view of results from previous investigations, which certainly do nothing to encourage belief in the value of bone meal as an anti-caries measure.

As your request was for information concerning current investigations, I shall make no attempt to provide you with lists of references to previous work on this subject. These, I presume, are available to you through the American Dental Association Index to Dental Literature and through other sources. Nonetheless, in case you have not come across them, I am sure your committee would be interested in a series of reports on bone meal published by the Council on Dental Therapeutics of the ADA. I enclose herewith a copy of one of these, entitled “Bone Meal Preparations Not Acceptable to the Council,” and a photostatic copy of a later report on a commercial preparation of bone meal known as Fluorossteol.

Your committee is no doubt aware of the functions of the Council on Therapeutics of the ADA and the pains that are taken by this organization to discharge them in conformity with the strictest scientific standards. Although the reports to which I have referred were published more than fifteen years ago, the council constantly reviews new developments and new claims, and I am assured by Dr. Sholom Pearlman, Secretary of the Council on Dental Research of the ADA, that no new evidence has been adduced that would call for revision of the opinions expressed in 1947 and 1948.

In fact, the findings of the ADA Council on Therapeutics have recently been corroborated by the results of research carried out in Sweden, where the suggestion that bone meal could act as a caries preventive was recently revived. The renewal of interest arose from beneficial effects produced in rodents. But Ericsson of Stockholm has provided information that could explain why phosphate additives cannot be expected to achieve the same effects in humans as in rodents. This is to be published in a forthcoming Special Supplement to the Archives of Oral Biology.

Ericsson has mentioned a further important point in his letter to me on this subject, vis-a-vis: Specialists on calcium phosphate metabolism and stone formation are divided as regards the possible risks for increased stone formation from calcium phosphate additives in foods. These facts should be borne in mind when considering studies on calcium phosphates or bone meal as caries-preventive food additives.

The most recent large scale experiment on humans is probably that carried out in the town of Falkenberg in Sweden, where more than 200 schoolchildren were served crispbread enriched with 10 to 12 percent of its weight in bone meal; a similar number of children in the population group received the same crispbread without the bone meal supplement. The results of this experiment showed that caries activity was not influenced over a period of two years. The investigation has been reported by Hall, Lind, and Nystrom in Svensk Tandlakare-Tidskrift (Vol. 55, p. 21, 1962).

Investigations in a related field are those concerned with the use of dicalcium phosphate as a dietary additive. As far as I know, the most recent of these was reported by Bibby to the Conference on Oral Biology, held in Bonn last year, and is, I believe, to be published in a forthcoming issue of the Journal of Dental Research. I am given to understand that this study has produced negative results.

I hope that the information provided in this letter will be of use to your committee. If there are any other points that you would like to raise, I know that the members of the commission would be glad to offer their assistance. To summarize the views that I have obtained, I would say that the Commission [of Dental Research] knows of no major investigations in progress in this field at the present time; and none of the experts I have consulted show any enthusiasm for a repetition of experiments that consistently failed to demonstrate caries-preventive properties in bone meal.

Yours sincerely,
Signed: B. Cohen
