This invention is a classic dental cow horn explorer that has been fitted with dycal style balls on the ends, for a completely new instrument designed to facilitate exacting placement of cavity liners and bases, spreading flowable composite underneath fillings by the Dentist, and placing Interim Therapeutic Restorations (ITR) such as fluoride releasing glass ionomer by the Dentist or Registered Dental Hygienist Expanded Functions (RDHEF).

Doctors then can reach over matrix bands and apply dental bases and liners, or spread flowable composite directly to the axial wall and pulp floor of their preps, and RDHEF's can access hard to reach interproximal, root and furcation areas to apply glass ionomer or other Interim Therapeutic Restorations where incipient caries have been hand excavated.

The high-speed turbine dental handpiece adapted for single safe use comprises a nose, a handle connected to the rear end of the nose, a plug connector disposed at the rear end of the handle, and a clip ring for fixing the handle and the plug connector, wherein the plug connector is provided with a first fixing slot at a side wall, the tail end of the handle is provided with a second fixing slot matched with the first fixing slot, the inner wall of the clip ring is provided with bumps matched with the first fixing slot and the second fixing slot, and when the clip ring is hooped on the plug connector, the bumps are embedded into the first fixing slot and the second fixing slot to limit and fix the handle and the plug connector. The invention effectively prevents the disposable dental handpiece from being reused in various ways, it is simple in structure and convenient to detach and thus can be conveniently detached and destroyed after being used, and in addition, with the disposable light-emitting component, whether the dental handpiece is used can be identified simply and clearly. According to the inventor, the concept of one handpiece for one patient for single use as advocated by the WHO in the field of oral health can be achieved, effectively solving the problem of iatrogenic cross infection in the field of stomatology. The invention is similar to a disposable syringe but with a more complex structure as a dental handpiece.

An interproximal reduction tool and method preferably includes at least one polishing strip; at least one abrasive wheel; and a low speed and high torque dental electric motor. First, the area between two adjacent teeth is manually polished with a plurality of polishing strips. The polishing strip is held between a forefinger and thumb and moved in a horizontal plane. Each abrasive wheel preferably includes an abrasive disc and a shaft. The abrasive disc includes a disc base and abrasive material. The abrasive material is adhered to opposing sides of the disc base. It is preferable to have an annular space between an outer edge of the disc base and an outer perimeter of the annular abrasive material. The low speed/high torque motor preferably utilizes an existing dental motor and modifies the dental motor to have a preferable gear reduction of at least 16:1.

This invention relates to a coolant for cooling a device for use in dentistry, the coolant comprising a Newtonian fluid having a viscosity greater than water. The invention also relates to a method of cooling a device for use in dentistry utilising the coolant, the coolant for use in a method of cooling a device for use in dentistry and an apparatus and kit comprising the coolant.

Devices and methods for dispensing material from a dental handpiece. In one example, the method includes receiving an input that indicates that an amount of the material is to be dispensed from the container of the dental handpiece. The method also includes rotating an electric motor to rotate an imbalanced mass to vibrate a vibration transmission element that vibrates the material in the container. The method also includes dispensing the amount of the material from the container with a piston based on the input.
