Abstract

Abstract The toothpick of the invention is shaped to reproduce faithfully the shape of the interstices between the teeth at the base of the teeth. For this purpose, it exhibits substantially trapezoidal sections decreasing toward the tip, with tapering curved sides. The upper front part (B, E, F) is concave and the lower front part (G, H, B) is curved upward. The base of the tip (HB) is impregnated with antiplaque, antibacterial and scented substances, while the sides (1') are coated with a toothpaste with a base of fluorine and a slight abrasive. The entire unit is protected by a film that is removed mechanically and by the action of saliva when the toothpick is inserted in the interstices between the teeth. The toothpick not only makes possible the removal of residue bodies from mastication, inserted in the interstices between the teeth, but especially removal of bacterial plaque and tartar with the deposition of antiplaque substances, as also brushing of the teeth and administration of fluorine, thus impeding caries.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 123 words
Improved toothpick, characterized by a tip having cross sections (figure 4) such as to reproduce the cross sections of the interstices (2, 2') between the teeth and in that it is coated and impregnated, at least in its lower part (AC, figure 4) with scenting and medicinal substances and on its sides (AB-CB) with dentifrice substances containing fluorine and slightly abrasive, the entire unit, protected by a film, so that the introduction of the tip in the interstices between the teeth automatically, with the aid of saliva, removes the film and deposits a discrete quantity of scenting and/or concentrated medicinal, antiplaque and disinfecting substance, simultaneously, with the sides, performing the administration of fluorine to the neck of the teeth and providing their brushing.
Claim 2
Dependent Claim 123 words
Improved toothpick, characterized by a tip having cross sections (figure 4) such as to reproduce the cross sections of the interstices (2, 2') between the teeth and in that it is coated and impregnated, at least in its lower part (AC, figure 4) with scenting and medicinal substances and on its sides (AB-CB) with dentifrice substances containing fluorine and slightly abrasive, the entire unit, protected by a film, so that the introduction of the tip in the interstices between the teeth automatically, with the aid of saliva, removes the film and deposits a discrete quantity of scenting and/or concentrated medicinal, antiplaque and disinfecting substance, simultaneously, with the sides, performing the administration of fluorine to the neck of the teeth and providing their brushing.
Claim 3
Dependent Claim 59 words
Toothpick as in claim 1, wherein: - the section, in its back part (1) is rectangular and changes into substantially trapezoidal sections (1 1 ) decreasing with the curved sides (AB and CB) toward the tip; - the upper front part (B, E, F, figure 2) is concave and the lower front part (G, H, B) is curved upward.
Claim 4
Dependent Claim 28 words
Toothpick as in claims 1 and 2, wherein at least the base (AC, figure 4) of the tip is impregnated with chlorhexidine as the disinfection and antiplaque agent.
