Theses cleaning products and methods are covered by two USA Patents:
6,685,474: Aqueous slurries useful for cleaning teeth.
6,861,049: Aqueous slurries useful for cleaning the tongue and throat.
The present inventions generally relate to compositions and methods useful for oral hygiene, and more particularly to such compositions and methods that are self-practicable by a human, or that can be practiced by a human on another human or other warm-blooded animal, for indicating the presence of and removing both plaque and calculus, as well as removing stains, adherent to tooth surfaces and methods that are useful for cleaning the tongue and throat - in all cases, of the human or other warm-blooded animal.
BRIEF SUMMARY OF THE INVENTION 6,685,474 (Aqueous slurries useful for cleaning teeth):
In brief, the present invention is directed to aqueous slurries useful
for removing both plaque and calculus, as well as stains, from affected
tooth surfaces when applied directly thereto so as to contact the calculus,
plaque or stains to be removed, and combined with mechanical removal of
the same. The present invention, in another aspect, is also directed to
methods, self-practicable by individual humans ("individuals"
or "patients") in need thereof or practicable by individuals
on patients or other warm-blooded animals, for removing both plaque and
calculus, as well as stains, from tooth surfaces that use the above slurries
in combination with mechanical application of the same, as well as mechanical
removal of the calculus and/or plaque and/or stains contacted with the
slurries.
In yet another aspect, the present invention is directed to kits, useful
for such removal, that include the above slurries or the components (i.e.,
charcoal and liquid portion) thereof, as well as a means for measuring
and mixing the components, a means for effectively applying the slurries
to affected tooth surfaces, and a means for removing the treated calculus,
plaque or stains.
More specifically, in one embodiment, the present invention is directed
to slurries, useful for removing calculus, plaque or stains adherent or
otherwise attached to tooth surfaces, wherein the slurries are formed
by combining finely-divided charcoal and a liquid portion so as to create
a slurry there from, the liquid portion comprising water, as well as alcohol,
ammonia or hydrogen peroxide. Such slurries have been found to be surprisingly
effective in removing both plaque and calculus adherent to tooth surfaces,
even when self-administered by an individual in need thereof.
In another embodiment, the present invention is directed to a method for
removing calculus, plaque or stains adherent to tooth surfaces, the method
being self-practicable by an individual in need thereof or practicable
by an individual on another individual or another warm-blooded animal
and using the above slurries. The method, as applied, for example, to
the removal of calculus, comprises: coating affected tooth surfaces with
an effective amount of any of the above slurries; then contacting, for
an effective period of time, the calculus to be removed and now having
the aqueous slurry coated thereupon; optionally, repeating the above steps
as necessary or desired; then, mechanically removing the contacted calculus
from the affected tooth surfaces; optionally, repeating the above steps
until a desired extent of removal of the calculus from the affected tooth
surfaces and oral cavity is accomplished; and, finally, mechanically and/or
rinsingly removing any residual slurry and loosened calculus from the
affected tooth surfaces and other tooth surfaces, as well as from other
surfaces of the oral cavity. Basically, the same method can be used to
remove plaque from affected tooth surfaces.
The coating step (i.e., first step), optionally combined with the contacting
step (i.e., second step) of the above method, also provides a method for
visually indicating the presence of calculus or plaque adherent to tooth
surfaces. The method for such indicating is another aspect of the present
invention.
In yet another embodiment, disclosed is a kit adapted for removing calculus, plaque or stains adherent to tooth surfaces in the oral cavity of an individual in need thereof. The kit is intended for use by the individual, with or without the assistance of another. The kit includes a quantity of any of the above aqueous slurries, or quantities of components thereof, namely, a quantity of finely-divided charcoal and quantities of the constituents of a liquid portion or a quantity of the liquid portion. The kit further includes, where the kit contains the components of the aqueous slurry to be used, a container and device adapted to mix quantities of the components in a desired ratio; an applicator for coating affected tooth surfaces with the slurry; a device adapted to cause, by mechanical action, the applied slurry to agitatively and frictionally contact the tooth surfaces and adherent plaque and calculus coated thereby and, further, to coat and contact, as described above, tooth surfaces not coated with the slurry by means of the applicator; a device adapted to mechanically remove the plaque and calculus, thus contacted, from the affected tooth surfaces; and, optionally, a device and/or rinsing agent adapted to mechanically or rinsingly remove any residual portion of the slurry, as well as any loosened plaque or calculus not already removed, from the affected tooth surfaces and other tooth surfaces, as well as the other surfaces of the oral cavity.
BRIEF SUMMARY OF THE INVENTION 6,861,049 (Aqueous slurries useful for cleaning the tongue and throat):
The present invention, in one aspect, is directed to aqueous slurries
useful for cleaning the tongue and throat of a warm-blooded animal, including
a human ("patient"), to remove contaminants, such as pathogens
and other debris, there from. Toward that end, the disclosed aqueous slurries
are applied to surface areas of the tongue and throat in need thereof.
In another aspect, the present invention is directed to methods for cleaning
the tongue and throat of a patient. The methods comprise contacting areas
thereof in need of cleaning with a disclosed aqueous slurry. The present
invention, in yet another aspect, is directed to kits that provide readily
used components for cleaning the tongue and throat of a patient by way
of the disclosed methods and aqueous slurries.
More specifically, in one embodiment, the present invention is directed
to aqueous slurries, useful for cleaning the tongue and throat of a patient,
wherein the slurries are formed by combining finely-divided charcoal and
a liquid portion, the latter comprising water and a biocide. Such slurries
are effective in cleaning areas of the tongue and throat of a patient
in need thereof.
In another aspect, the present invention is directed to methods for cleaning
the tongue of a patient to at least reduce the contamination thereof.
A representative method comprises: contacting an area of the tongue surface
in need thereof with a disclosed aqueous slurry so as to contact contamination
thereon for a period of time; removing at least a portion of the contacted
contamination and used aqueous slurry from the area of the tongue surface;
optionally, repeating the contacting and removing steps so as to effect
a desired degree of cleaning; and, optionally, removing residual amounts
of the aqueous slurry, finely-divided charcoal, liquid portion, and/or
contacted contamination from the tongue, as well as generally from the
oral cavity of the patient. For the disclosed method, the aqueous slurry
used may be formed from the finely-divided charcoal and liquid portion
prior to contacting the area of the tongue surface with the slurry, or
after separately contacting the area of the tongue surface with the finely-divided
charcoal and liquid portion.
In a related embodiment, the present invention is directed to a method
for cleaning the throat of a patient to at least reduce contamination
thereof. The disclosed, representative method therefore comprises the
same basic steps as the above-described, representative method for cleaning
the tongue of a patient, except that areas of the throat, rather than
of the tongue, in need thereof are contacted with a disclosed aqueous
slurry.
Another embodiment of the present invention is directed to yet another aspect thereof, namely, a kit that is useful for cleaning the tongue and/or throat of a patient to reduce contamination thereof, in providing components that can be readily combined and used for that purpose. More specifically, a representative, disclosed kit comprises: a contained quantity of a disclosed aqueous slurry, or a contained quantity of finely-divided charcoal and, separate there from, a contained quantity of the liquid portion, or of the components of the liquid portion of the slurry; optionally, a mixing device adapted to mix the finely-divided charcoal and the liquid portion to form the aqueous slurry; optionally, where the contained quantity of finely-divided charcoal and the contained quantity of the liquid portion, or of the components of the liquid portion, are provided separately, an empty container adapted to provide a reservoir for combining and mixing the quantities of the liquid portion, or components thereof, and of the finely-divided charcoal in desired ratios; optionally, a first contacting device adapted to effect contact of an area of the tongue and/or throat surface with the aqueous slurry and; optionally, a second contacting device adapted to agitatively and frictionally contact the area of the tongue surface with the aqueous slurry; optionally, a removal device adapted to remove the contacted contamination and used aqueous slurry from the area of the tongue surface; and, optionally, a device and/or rinsing agent adapted to remove residual aqueous slurry, components of the liquid portion, finely-divided charcoal and/or contacted contamination from the tongue, throat and other areas of the oral cavity of the patient.
