Abstract

The subject of the present invention is a device for demonstrating the effectiveness of fluorine in the prevention of dental caries. A demonstration device comprises a tube 1 containing a solution 2 of dilute acetic acid in which are immersed small tooth-shaped objects, namely A consists of fluorine and B of calcite, the tube being closed by a screw cap 4 provided with a seal 5.

Description

La présente invention a pour objet un dispositif de démonstration de l'efficacité du fluor dans la prévention de la carie dentaire. The present invention relates to a device for demonstrating the effectiveness of fluorine in the prevention of dental caries.

Le dispositif de l'invention comprend un tube 1 contenant une solution 2 d'acide acétique étendue dans laquelle baignent de petits objets 3 (A,B) en forme de dents. The device of the invention comprises a tube 1 containing a solution 2 of extended acetic acid in which are bathed small objects 3 (A, B) in the form of teeth.

Le tube est refermé par un bouchon à vis 4 pourvu d'un joint d'étanchéité 5 ; l'extrémité du tube comportant le bouchon est pourvue d'un capuchon élastique 6,6 coiffant de façon étanche l'extrémité du tube. The tube is closed by a screw cap 4 provided with a seal 5; the end of the tube comprising the stopper is provided with an elastic cap 6,6 sealingly covering the end of the tube.

L'objet en forme de dent A est constitué de fluorine (CaF2), substance minérale inattaquable par l'acide fluorhydrique. The tooth-shaped object A consists of fluorine (CaF2), a mineral substance unassailable by hydrofluoric acid.

L'objet en forme de dent B est constitué de calcite (CaCO ) mais peut aussi comporter
a avantageusement du phosphate de calcium et du plâtre agissant comme liant.The tooth-shaped object B is made of calcite (CaCO) but may also include
advantageously has calcium phosphate and plaster acting as a binder.

La solution d'acide acétique peut lors de son introduction dans le tube être saturée de gaz carboniquc (CO2) ; on peut encore au lieu de cette adjonction d'acide carbonique, placer dans le tube un petit fragment de calcite pure. The acetic acid solution can be saturated with carbon dioxide (CO2) when it is introduced into the tube; one can still instead of this addition of carbonic acid, place in the tube a small fragment of pure calcite.

La présente invention sera mieux comprise à la description qui va être donnée du fonctionnement du dispositif, et de la démonstration en résultant, en relation avec la figure de la planche unique annexée qui montre le dispositif en coupe. The present invention will be better understood from the description which will be given of the operation of the device, and from the resulting demonstration, in relation to the figure of the single sheet appended which shows the device in section.

Fonctionnement
Lorsque I 'on débouche très légèrement le bouchon 1, le gaz contenu au-dessus de la solution 2 s'échappe, la pression diminue au-dessus de cette derniè re, l'equilibre ionique est déplacé et l'anhydride carbonique libéré à la surface de la dent en calcite avec production de bulles 7. Le tube peut être refermé et l'expérience répétée plusieurs fois. Operation
When the plug 1 is slightly opened, the gas contained above the solution 2 escapes, the pressure decreases above the latter, the ionic equilibrium is displaced and the carbon dioxide released to the calcite tooth surface with production of bubbles 7. The tube can be closed and the experiment repeated several times.

DEMONSTRATION
Tandis que la dent en calcite est attaquéc ( < le préférence avec apparition d'une tache noire sous jacente à la couche superficielle de calcite), la dent en fluorine reste intacte, et prouve l'effet bénéfique du fluor en matière de prévention des caries dentaires.DEMONSTRATION
While the calcite tooth is attacked (<the preference with the appearance of a black spot underlying the surface layer of calcite), the fluorite tooth remains intact, and proves the beneficial effect of fluoride in terms of caries prevention dental.

Suivant une autre forme de réalisation, on pourrait rapporter des objets en forme de dents sur une palette en carton, certaines des dents étant en calcite (avec éventuellement plâtre et phosphate de chaux), d'autres dents étant en fluorine (F2Ca) ; le tube ci-dessus décrit est remplacé par un applicateur à embout de feutre contenant la solution diluée d'acide acétique. L'application de l'acide acétique fera apparaitre la carie sur la dent en calcite tandis que la dent en fluorine restera intacte. According to another embodiment, one could bring back tooth-shaped objects on a cardboard pallet, some of the teeth being made of calcite (with possibly plaster and lime phosphate), other teeth being made of fluorite (F2Ca); the tube described above is replaced by a felt tip applicator containing the dilute acetic acid solution. The application of acetic acid will cause cavities to appear on the calcite tooth while the fluorite tooth will remain intact.

Suivant une autre variante, les dents disposées sur la palette sont en calcite avec carie
sous-jacente et on propose deux applicateurs, l'un contenant une solution de fluorure de sodium, 1 'autre contenant une solution d'acide acétique ; l'expérience cons a applique 'abord sur certaines dents la solution de fluorure de sodium, à laisser celle-ci agir un certain temps, puis à appliquer la solution d'acide acétique sur toutes les dents ; celles des dents ayant subi l'application du composé fluoré résisteront beaucoup plus à l'attaque acétique.According to another variant, the teeth arranged on the pallet are made of calcite with decay
underlying and two applicators are proposed, one containing a solution of sodium fluoride, the other containing a solution of acetic acid; experience cons has applied the sodium fluoride solution first to certain teeth, let it act for a certain time, then apply the acetic acid solution to all the teeth; those of the teeth having undergone the application of the fluorinated compound will resist much more the acetic attack.

Bien que l'on ait décrit et représenté une forme particulière du dispositif de l'invention, il doit être compris que cette dernière n'est pas limitée à cette forme mais qu'elle s'étend à tout dispositif comportant les caractéristiques générales sus-énoncées.  Although a particular form of the device of the invention has been described and represented, it should be understood that the latter is not limited to this form but that it extends to any device comprising the general characteristics mentioned above. set out.
