In a preferred embodiment, the first section is a hard probe that is configured for probing a patient's teeth for carious lesions.

## Background
TECHNICAL FIELD
The presently disclosed and claimed inventive concept(s) generally relate to an apparatus for probing for carious lesions, and more particularly to a disguised probe for probing for carious lesions.
BACKGROUND
The American Dental Association estimates that there are approximately 183,000 active, licensed dentists in the United States. A large number of dentists in the United States use sharp dental explorers to probe for carious lesions. The probes are also used to distinguish between normal and softened dentin, to identify subgingival calculus, and to evaluate the marginal integrity of restorations. The use of a probe, also known as an explorer or sickle probe in the dental field, is well known throughout the dental field and is taught in dental school and practiced by practicing dentists. The explorer is generally used by running the sharp metal probe over a client's teeth. When the explorer catches or resists removal after the insertion into a pit or fissure with moderate to firm pressure and is accompanied by one or more of a softness at the base of the area, opacity adjacent to the pit or fissure, or soft enamel adjacent to the pit or fissure, the dentist typically recognizes a sign of caries. The dental explorer is typically an elongate metal probe that is maintained by sterilization and sharpening. Further the use of a disposable explorer is possible or an explorer with a disposable tip. The explorers can be made of, for example, a hard metal or a hard plastic. Dental explorers are also used to remove plaque from the examination area of a patient's tooth. The plaque is an indication that the area beneath the plaque needs to be examined for the presence of carious lesions. This is typically performed by a scraping action of the explorer shaft or by use of the explorer's tip to expose the underlying enamel surface. The tip of the explorer is also used to determine the presence or absence of surface roughness on the surface of any noncavitated area. In this process the tip of the explorer is moved gently across the surface of the noncavitated area in search of surface roughness that indicates enamel decay.
SUMMARY OF THE DISCLOSURE
The purpose of the Summary is to enable the public, and especially the scientists, engineers, and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection, the nature and essence of the technical disclosure of the application. The Summary is neither intended to define the inventive concept(s) of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the inventive concept(s) in any way.
The present application discloses a method and apparatus for disguising a dental probe from a patient. This is applicable, for example, in the field of pediatric dentistry, or special needs dentistry. What is disclosed is a dental tool having a first section and a second section. In a preferred embodiment, the first section is a hard probe that is configured for probing a patient's teeth for carious lesions. The second section of the tool has a structure of an object that is familiar to a patient and is used to disguise the presence of the hard probe. For example the second section can be in the shape of a toothbrush, a lollypop, or even a figurine that is familiar to a child. This could be an action figure figurine or similar object. In this way, the dental tool can be used on a child or special needs patient or anyone else and lead to a lower feeling of fear than is experienced with the use of a naked dental explorer. The second section of the dental tool can have a first end and a second end and a length between the first end and the second end. A plurality of bristles is located near the first end and extends outward from the first end. This generally has the shape of the head of a toothbrush. The hard probe is located near the first end in a preferred embodiment. The hard probe can extend outward from the first end either parallel to or in the same direction as the plurality of bristles or in a different direction. Also disclosed is a dental tool in which the hard probe is located within an outer circumference of the plurality of bristles or it can be located on the outer periphery of the plurality of bristles. In a preferred embodiment, the probe is an elongate metal probe. This metal probe can have a rounded section that can be used more efficiently for reaching around a tooth and exploring the back of the tooth. The probe again can be located within the outer perimeter of the bristles, as part of the outer perimeter of bristles, or outside the outer perimeter of bristles.
The dental tool can have a mechanism by which the first end of the dental tool can be removed. This can allow for sterilization or replacement of first end of the dental tool.
The dental tool can have a light in a preferred embodiment for illuminating the working area in which the dental tool is being used. This light can comprise an LED or any other similar light known in the art or discovered in the art. The type of light is not important to the spirit of the invention
The dental tool can have a rechargeable energy source that provides power to the light or it can have a replaceable energy source such as a battery to provide power for the light.
Also disclosed is a method for probing for carious lesions in which the method includes providing a device for probing for carious lesions in a mouth. The device has a first section and a second section. The first section of the device is a hard probe and the second section of the device is a section configured to disguise the dental probe such that the dental tool does not appear to include a hard probe. The dental tool subsequently used to probe a tooth for the presence of carious lesions.
In a preferred embodiment, the second section of the dental tool used in the method has a first end and a second end and a length between the first end and the second end. The dental tool has a plurality of bristles located proximate the first end of the dental tool and extending outward from the first end of the dental tool in a generally normal direction to the dental tool. The hard probe, in a preferred embodiment, is located within the outer perimeter of the plurality of bristles, although it can be located outside the outer perimeter or even directly in the outer perimeter of the bristles.
