In the modern era, there is still need to get the conditions that can make our world free from the dental disease advert Dental Caries and for this purpose there is need to get the proper diagnostic methods that can help in the detection of Dental Caries at an early stage so that the great damage to the tooth can be minimized by the dentist.
Earlier the methods that were used to diagnose the Dental Caries and also which are the first procedure of diagnosing Dental Caries even in the present time, are known as Conventional Diagnostic Methods but after that there has been so much advancing in this field and the results are the Advanced Diagnostic Methods for detecting Dental Caries.
Advanced Diagnostic Methods
Digital Fiberoptic Transillumination
Digital Fiberoptic Transillumination is a relatively new method of detecting Dental Caries with modern technology. In this technique of detecting Dental Caries, there is make the use of fiberoptic light for detecting caries and the image can be seen with the help of digital camera attached to it. The main principle of detecting Dental Caries by this method was that the sound tooth materials absorbs very minimum amount of light and let the other light to pass through it but that was not true in case of affected tooth as it absorbs maximum amount of light and thus it appears dark.
Electrical Conductance Measurement
In this method of detecting Dental Caries, the main motive is to measure the electrical conductance by the various teeth. In this method the teeth with affected part was supposed to show high electrical conductivity and the other with low. In this method all the teeth are cover with conducting media and then the electrical conductance has to be measured to detect Dental Caries.
But the problems in this method are the differences that come when A.C. Or D.C. current is used.
It has been proved that the induced fluorescence of enamel is lower in areas of reduced mineral content and that is the main principle of detecting Dental Caries by this method.
The scientific basis of this technique is that argon laser is used to illuminate the tooth and the tooth emits yellow light due to auto florescence but the one with Dental Caries reduces the amount of emitted light.
This is the main method of detecting Dental Caries by the advanced technique and the main principle behind detection is that the bacterial metabolites with in the lesion exhibits increased fluorescence when illuminated with diagnodent.
By this method it is easy to find out the residual and minimal caries. A laser diode is used in this method with particular wavelength of 655nm and this causes the stimulation of light of various wavelengths that reaches the control unit and the control unit provides the reading that is compared with the sound enamel reading and thus the damage can be detected.
