In clinical examination there are distally food impaction in third molar area with incipient caries, the best method to diagnose incipient and recurrent caries before any x-rays is:
a- Visible light.
b- Transillumination fiberoptic light. ***
c- U V light
d- Digital X ray with Transillumination light.
The transillumination before the appearance of the "led technology" was only used for the detection of proximal caries in the incisors.
At present, given the light output of said devices, it can be used for the investigation of proximal and occlusal caries of the posterior dental pieces.
A daylight led lamp (5500 ºK) is used with its optical fiber, as shown in the lower right photograph.
Visible light is sent by means of an optical fiber to the surface of the tooth, where it propagates through the tissue to the opposite surface.
The result is an image that results from the distribution of light a inside the tooth.
A process of tooth decay in enamel and dentin has the particularity of an opaque body to reflect the light, consequently the observation on the opposite surface would generate a dark image.
But this phenomenon that we have just explained is not exclusive to caries, hypoplasias (impaired enamel development) and enamel opacities due to fluorosis and other chemicals, such as tetracycline and metallosis of dental amalgams, can affect the light transmission inside the dental piece, generating opaque figures or images.
In general, transillumination is an ideal complement in the visual diagnosis of enamel caries (sensitivity 96% and specificity 74%) and dentin (sensitivity 89% and specificity 92%).
A well trained eye and clinical practice can complement the visual diagnosis of initial and moderate caries in premolars and molars.
Advantages of transillumination:
- Detects initial caries
- Real time diagnosis
- Does not use ionizing radiation
To standardize the diagnosis of caries through transillumination, there are scales that classify the severity of the lesion in proximal and occlusal:

OPTICAL FIBER TRANSILUMINATION DEVICE:
The following invention is about an optical fiber transilluminator for visible and invisible light ranges as well as its arrangement and arrangement of the optical fiber and its new components that significantly reduce the shadow generated by a groove in the transilluminator head are also reduced the critical levels of heat energy that affect the other end of the optical fiber that is attached to a metal connector when it is introduced to the light generating source, as well as the incorporation of a built-in dark color ring, to the light diffuser head that will greatly reduce residual light that prevents a good definition of scanned areas, this gives the transilluminator versatility and durability in prolonged and constant work cycles .
