摘要： An interproximal dental tool for use by dental practitioners which contains several significant improvements over prior art interproximal dental tools which has an upper surface extending to a sidewall and a body section which in turn grasps a razor or blade member having a blade extending outwardly from the interproximal dental tool and which is placed between the patient's teeth to grind portions of teeth between two adjacent teeth. The tool is used for professional practice only and not by consumers. The significant improvements over the prior art interproximal dental tools are as follows: The exterior top surface and the exterior side surfaces of the present invention interproximal dental tool are made of grippable material which is primarily made of rubber.

摘要： A dental restorative composition is provided that includes a polymerizable resin, a substantially translucent structural filler, a nanofiller having a mean particle size less than 100 nm, and at least one rheology-modifying additive. In one embodiment, the structural filler has a refractive index substantially similar to that of the polymerizable resin, a coarse particle fraction, and a fine particle fraction having a mean particle size greater than 0.1 μm and smaller than the mean particle size of the coarse particle fraction. The relative ratio of the coarse particle fraction to the fine particle fraction is in the range from about 12:1 to about 2:1 by volume, the particle size distribution of each fraction is essentially monomodal, and the D(90) of the fine particle fraction is less than or equal to the D(10) of the coarse particle fraction.

摘要： A hand held dental instrument for curing light-curable compounds including a housing with a handle portion and a barrel portion configured for being manipulated for positioning a tip end of the barrel portion proximate to a curing site. A plurality of solid state, light-emitting elements are mounted in a collective array to collectively form a beam of light. The array of elements is operable for collectively emitting a beam of light having wavelengths within a band of wavelengths and at a power to cure a dental compound. The array of elements is positioned proximate to the tip end of the barrel portion and the emitted light beam from the array illuminating a curing site. A radiation focusing device is positioned proximate the array of elements at the tip end of the barrel portion to focus the beam of light before it illuminates the curing site.
