TREATMENT MEMBER
Abstract
A member for use in the treatment of caries in the teeth with
fluoride or other chemicals which are carried by a section of the
member which may be detachable. The member is worked between two
teeth at a contact area to place the detachable section in contact
with the teeth. The chemical agent is applied to the detachable
section either before or after it is placed in contact with the
teeth. The detachable section remains between the teeth when the
rest of the member is removed, and preferably dissolves in the
mouth when wet.

Claims
Having thus described my invention, I claim:
1. A dental caries treatment device comprising a thin plastic,
fabric, paper or metal foil strip carrier dimensioned in thickness
to be sufficiently thin to fit between two teeth at a contact area
thereof and slightly separate those teeth from each other, and a
thin caries treatment section which ultimately dissolves when wet
with saliva, said treatment section including absorbent material
affixed with adhesive to said thin strip carrier and covering an
aperture at the bottom edge of the strip, said absorbent material
being dissolvable when wet with saliva, said thin strip carrier
having a linearly extended leading strip edge for entering the
contact area first so that said thin strip carrier can be worked
between the teeth at the contact area to place said treatment
section at the contact area for detachment to remain between the
teeth when said carrier is removed, and said detachable treatment
section remaining between the teeth and carrying a caries treatment
material for treating the teeth particularly at the contact
area.
2. The dental caries treatment device as claimed in claim 1 which
said treatment material comprises fluoride.
Description
BACKGROUND OF THE INVENTION
At the present time, fluoride materials are applied by dentists to
the teeth of their patients usually by painting on a liquid
solution. The liquid may not effectively reach some areas between
teeth, particularly where two teeth are in contact with each other.
Thus, it would be desirable to have a more thorough and effective
way of treating areas between teeth with fluoride or other
chemicals.
SUMMARY OF THE INVENTION
The present invention provides a treatment member for use in
treating contact areas between teeth especially where incipient
carious lesions occur by working the member between the teeth to
place a detachable section of the member between the teeth. The
fluoride or other chemical agent which is to accomplish the
treatment may be applied to the detachable section at the time of
manufacture of the member, or just before or after placing the
member between the teeth. The detachable section remains between
the teeth when the rest of the member is removed and serves to
treat the area between the teeth with fluoride or the like.
Accordingly, it is an object of the invention to provide a member
which is effective in applying fluoride or other chemicals to areas
between teeth.
Another object of the invention is to provide a treatment member
having a detachable section which will remain between teeth when
the member is worked between the teeth and then removed.
A further object of the invention is to provide a treatment member
with a detachable section which dissolves in the mouth when
wet.
Other objects of this invention will appear from the following
description and appended claims, reference being had to the
accompanying drawings forming a part of this specification wherein
like reference characters designate corresponding parts in the
several views.

AS SHOWN ON THE DRAWINGS
The treatment member 10 shown in FIG. 1 includes a rectangular
strip 12 made of metal foil such as gold foil, aluminum foil, or
steel foil or other suitable thin material such as plastic, fabric
or paper. The strip 12 has an aperture 14 which in the embodiment
of FIG. 1 opens at the bottom edge 16 of the strip. The aperture 14
is covered with absorbent material 18 which is the detachable
section of member 10. The absorbent material 18 may be adhered at
20 to the strip edge about the aperture 14 as with adhesive. The
absorbent material 18 preferably comprises material which will
dissolve when wet by saliva in the mouth of the patient. Some forms
of paper are suitable for the absorbent covering 18.
Another embodiment of the invention is shown in FIG. 2. In this
embodiment, the member 22 includes a strip portion 24 and a
detachable section in the form of an absorbent portion 26. The
absorbent material 26 covers an aperture 28 in the foil 24, the
aperture being centered in the strip. The absorbent covering 26 may
be adhered to the strip 24 at the area 30 surrounding the aperture
28. The material of strip 24 and absorbent covering 26 may be the
same as strip 12 and absorbent covering 18 respectively.
The manner in which member 10 or member 22 is used is illustrated
in FIG. 3 and 4. The member 10 is shown in these views, but it will
be understood that member 22 could be used in substantially the
same manner. The treatment member is worked between two teeth as
shown to place the absorbent material 18 at the area between two
teeth where they normally contact each other. The absorbent
material 18 (or 26) carries a chemical agent which is transferred
to the teeth as it comes in contact with them. The member will
normally be used at the present time to apply a fluoride material
to the teeth, but it can be used to apply other chemicals. The
fluoride material may be stannous fluoride, sodium fluoride, or
possibly monofluoro-phosphate. The fluoride or other chemical is
preferably applied to the absorbent material at the time the
treatment member is manufactured. However, it may be possible in
some cases to make treatment members without fluoride impregnated
therein, and apply the fluoride to the absorbent material just
before the treatment member is worked between the teeth.
Alternatively, the treatment member can be worked between the
teeth, and a liquid fluoride solution then applied to the absorbent
material which will spread the liquid to the area between the
teeth.
Ordinarily, when fluoride solution is applied to children's teeth,
interproximal caries are somewhat inhibited. However, in areas
where caries have already begun, and in adult teeth, which do not
absorb fluoride as readily as children's teeth, a concentrated
application of fluoride is desirable directly at the site. A cavity
32 in the enamel 34 of a tooth is shown in FIG. 5, the cavity being
in an interproximal position where it can be treated with the
treatment member of the invention.
The detachable section 18 or 26 should remain between the teeth
when the strip 12 or 24 is removed. An advantage of the treatment
member 10 as compared to treatment member 22 is that since the
aperture 14 opens at the bottom edge 16 of the strip 12, the
absorbent material 18 is more likely to remain between the teeth
when the foil 12 is removed.
FIG. 6 shows an embodiment of the invention wherein the treatment
member 40 consists of a strip 42 having two detachable sections 44
and 46, preferably absorbent material, adhered to the outer surface
of strip 42. A longer strip of this type could be provided with a
plurality of detachable sections and supplied in the form of a
roll. The specific materials of the strip 42 and the sections 44
and 46 may be in accordance with the description of FIG. 1.
FIG. 7 shows a treatment member 50 consisting of a strip 52 having
a detachable section 54 projecting from one end and adhered to the
left end of the strip 52. The strip 52 could be inserted between
the teeth starting at the right end and then worked through until
the detachable section 54 is between the teeth. When the strip 52
is removed, the detachable section 54 detachs from strip 52 and
remains between the teeth. The materials of strip 52 and section 54
may be in accordance with the description of FIG. 1.
FIGS. 8 and 9 show still another embodiment. In this embodiment,
the treatment member 60 consists of multiple layers. There are two
layers 62 and 64 forming a strip with a detachable section in the
form of a layer 66 sandwiched between layers 62 and 64. The layers
62 and 64 and the detachable section 66 may be in accordance with
the description of FIG. 1.
FIG. 10 shows a treatment member 70 consisting of a wedge-shaped
member 72 having a detachable section 74 adhered to its outer
surface. The treatment member 70 is designed to have the left end
portion as viewed in FIG. 10 inserted between the teeth until the
detachable section 74 is in contact with the teeth. Then when the
wedge 72 is removed from the teeth, the detachable section 74
remains between the teeth.
FIG. 11 shows a treatment member 80 have a modified form of wedge
82 carrying a detachable section 84. This embodiment is similar to
FIG. 10, but the lower end of the wedge is designed to be inserted
downwardly or upwardly between two teeth until the detachable
section 84 is between the teeth. Then the wedge 82 may be removed,
and the detachable section 84 remains between the teeth.
In each of the embodiments, the detachable section may have a
tearable joint or a soluble joint or a dissociable joint with the
remainder of the treatment member. For example, if the detachable
section is made of paper, the paper may be flimsy enough so that
when it is wet, it will tear away from the remainder of the
treatment member and remain between the teeth.
The detachable section in each embodiment may have fluoride or
other chemical material incorporated in it at the time of
manufacture of the treatment member. Alternatively, the fluoride or
other chemical may be applied to the detachable section just before
or just after the treatment member is placed between the teeth.
The detachable section preferably dissolves in the mouth as
previously explained. Thus, even though the detachable section
remains in the mouth when the strip is removed, it dissolves when
it is wet by saliva over a moderately extended period of time.
Thus, the invention provides a treatment member which is more
effective in applying fluoride or other chemical agents to areas
between teeth than known treating methods and devices. The
treatment member can be manufactured economically from readily
available materials. It has the further advantage that although the
detachable section remains between the teeth when the rest of the
member is removed, the detachable section ultimately dissolves.
