It is well recognized that proper oral hygiene requires the frequent and regular cleaning of the teeth to remove food particles, fibers, plaque and the like. Dental research has also shown that the more efficient removal of plaque, with either chemical or mechanical means, the better the oral hygiene. This is very important in the prevention and treatment of gingivitis and periodontitis.
It is, therefore, an important object of the present invention to provide a method and device which complementing normal dental care will aid in the mechanical cleaning of the teeth and plaque removal.
l-leretofore such mechanical cleaning of teeth has been performed utilizing dental floss or toothpicks formed of balsa wood, plastic or other wood materials, These devices are subject to disadvantages. Toothpicks are relatively weak devices and fracture and splinter upon occasion. A toothpick can also become impacted between tightly adjoining teeth. Dental floss can be accidentally cut by a sharp cusp. Moreover a great deal of force is necessary to force dental floss into the interproximal space between contacting, adjoining teeth. Such force can be sufficient when a tight contact is encountered that the rebound caused by the force used to pass the floss through the contact traumatizes the gingival tissue.
It is, therefore, also an important object of this invention to provide a method and device for cleaning the teeth which will permit access to the inter-proximal space betwen adjoining teeth even in tight contact and which will not be subject to the disadvantages of dental floss and toothpicks described above.
These and other objects of the invention which will become more apparent hereinafter are obtained utilizing an inter-proximal cleaning device in the form of a non-cutting blade having a thickness approximating that of the interproximal spacing of contacting, adjoining teeth. The blade is inserted between adjoining teeth and then is caused to slide back and forth in such space. The thickness of the blade is critical and should be 0.002 inches which is exactly the inter-proximal spacing of contacting, adjoining teeth. The blade, however, can be thinner to a degree and thus can be as thin as 0.0015 inch. The edges of the blade are rounded in order to avoid injury to the gingival tissue, and the blade is preferably made of flexible material, such as hard tempered stainless steel. The width of the blade is on the order of 0.2 inches to 0.3 inches and the working length can be from 0.3 inches to 0.8 inches. Typical materials are readily available in the dental profession as matrix band material. This material is commonly used as a form about the sidewall of a tooth in the interproximal space when filling cavities extending into such sidewall.
In a preferred form of this invention the blade is mounted on a handle having a bowed shape lengthwise the handle. The handle should be rigid and is of a width equal to that of the blade or slightly larger and has thickness so that it can be readily grasped between the thumb and index finger. In accordance with this invention it is important that the handle have distinct bowed shape in order to conform to the shape of the jaw, thus enabling the user to insert the blade in hard to reach places, such as in the molar region. When the handle is viewed edgewise it appears to be arcuate and extends through an arc of about 10 to 45".
For a more complete understanding of the practical application of this invention reference is made to appended drawings in which:
FIG. 1 is an edge view of an inter-proximal cleaning tool in accordance with the present invention showing the manner in which it is grasped between the thumb and index finger;
FIG. 2 is a view of the same blade with the hand rotated showing insertion of the blade in the molar region;
FIG. 3 is an enlarged section taken at line 33 in FIG. 2;
FIG. 4 is a perspective view of the tool shown in FIGS. 1, 2 and 3; and
FIG. 5 is a perspective view of another tool in accordance with this invention.
In the drawings the reference numeral 10 designates an inter-proximal cleaning tool. Cleaning tool 10 includes a handle 11, a blade 12 on one end 16 of the handle and a balsa wood pick 13 on the other end 22 of the handle. Handle 1 1 itself is formed of hard plastic and in the illustrated case is about one and one-fourth inches long, three-eighths of an inch wide and oneeighth of an inch thick. Handle 11 is curved lengthwise, such that it has a bowed form and its lateral surfaces 14 and 15 are portions of coaxial cylinders extending through arcs of approximately 30 each.
In operation, as seen in FIGS. 1 and 2, tool 10 is grasped between the thumb and index finger, which rest on lateral surfaces 14 and 15, respectively. End 19 of blade 12 is then inserted, for example, into the interproximal space between a pair of adjoining molars, and blade 12 is extended through such space. Blade 12 then is caused to slide back and forth and up and down to remove plaque and foreign material in the interproximal space. Such insertion is readily made even when the adjoining teeth are in tight contact.
FIG. 5 shows another embodiment 10' which is essentially the same as tool 10, except that the balsa wood pick 13 is replaced by an intregal extension 22 of the end of handle 11' remote from blade 12 and is pyramidal in shape ending in a point.
