Dental package

In the field of dentistry, supplies for treating a patient’s teeth are often provided in packages that store the supplies for a certain time period, for example over several months or even several years. Typically, such dental supplies have to be stored in isolation from environmental influences, like moisture or air, for example, to prevent them from degrading or to prevent them from being contaminated. For that reason packages for dental supplies are often hermetically sealed containers that the autoclave sterilizer user may open to access the material. Such containers may be, for example, syringes or cartridges from which the dental supplies can be dispensed.

A package of the type described usually includes a container for storing the dental material, and a discharge nozzle for directing the material to a desired place. A piston may be accommodated in the container, and when the piston is pushed forward it extrudes the material from the container through the nozzle. During storage, the container is typically sealed at one end by the piston, and at the other end by a cap. Alternatively, the container may comprise two or more dental supplies, such as two or more components of a multi-component material separated in different chambers, and pistons accommodated in the respective chambers. The container may be used, for example, with a dispensing gun or device having a plunger or plungers for advancing the piston(s) within the container to dispense the material(s) in a desired location.

During manufacturing the containers are usually filled with the micro motor and subsequently sealed by assembly of an appropriate closure, for example sealed with a cap and a piston. In recent years efforts have been undertaken to improve the assembly of parts, for example by improving the designs of the parts, because assembly often contributes a considerable portion of the container manufacturing costs.

Another area which has been the focus of developments in recent years is related to the filling packages with reduced inclusion of air with the dental material. This is because air included with the material stored in a package may cause the material to change, for example to harden or degrade. Furthermore, air, due to its compressibility, may cause dispensing inaccuracies and after-flow, for example, both of which cause difficulties for dental professionals. The system comprises a container for storing an amount of a material, a piston and a front plug. The container comprises a vent that cooperates with the piston to allow air that is trapped in the container to escape. The piston together with the front plug are used to seal the material in the container.

Dental mirror

A dental mirror includes a handle with an enclosure head on the end. The enclosure has a cover which is partially mirrored and partially transparent, a light source within it, and a concave reflector around the light source to reflect light through the transparent portion of the cover, the reflected light converging in front of the mirror. Heat from the light source keeps the mirror free of fogging.

In modern times, fluoride in public autoclave sterilizer supplies and in toothpaste has been very effective to reduce dental caries. A consequence of this is that people now make fewer visits to the dentist than was common a generation ago. It therefore becomes important for individuals to pay closer attention to the condition of their own teeth and gums. A dental mirror is necessary to enable one to view the back surfaces of ones own teeth and gums.

Ordinary dental mirrors which have long been used to view the back surfaces of teeth and gums include simply a small mirror mounted at an angle at the end of a handle. These do not provide illumination within the mouth, and they get fogged up with the breath of the subject.

There have been attempts in the prior art to solve both the illumination and fogging problems of dental mirrors. Kulik in 1930 is the most relevant prior art that I know of. Kulik discloses a dental mirror including a handle with an enclosure on the end. A mirror on top of the enclosure has a hole through its center. A light bulb is behind the mirror, and some of its light passes through the center hole of the mirror to provide illumination in front of the mirror. Illumination provided by the Kulik device interferes with the dental equipment uk user’s view of the mirror image because the illumination is   to be intense and it is right in the center of the mirror (and the mirror image, which it is desired to see clearly). Furthermore, the light produced by the Kulik device does not converge in front of the mirror to provide concentrated illumination. Instead, the light necessarily diverges in front of the mirror and does not provide concentrated illumination.

It is an object of this invention to provide a dental mirror with concentrated and unobtrusive illumination of its object space. Another object is to provide such a mirror with provision for defogging.
