Abstract: There is provided a toothbrush having an elongate body provided with a handle portion at a first end and a utility portion at a second end opposite to the first end, (a) wherein the utility portion is provided with a platform from which a plurality of tufts of cleaning bristles are extended, (b) wherein the cleaning media is provided with a front region, opposite side regions and a rear region which together forming a circumferential area surrounding a middle region of the cleaning bristles, (c) wherein the tufts of cleaning bristles located at the middle region are formed into at least two peaks configured for insertion into adjacent gaps between successive teeth, (d) wherein the tufts of cleaning media forming the peaks are substantially taller than the tufts of cleaning media along the side regions, and (e) wherein distal end of the two peaks are separated by a distance from 8.15 mm to 9.15 mm.

Abstract: A dental measuring device in the form of a caliper includes a pair of elongate jaws, each having an abutment surface. The jaws are movable between a first zero position wherein the abutment surfaces are contiguous with each other and a second position wherein the abutment surfaces are displaced from each other, this displacement defining a measured distance. A distal end of each jaw and includes an arrowhead formation wherein the arrowheads at least partially overlap when the jaws are in the first position.
