EXISTING METHOD
Quantitative Light-induced Fluorescence (QLF) is a technique currently employed to detect small changes in enamel mineral content.
Its widespread implementation are still hindered by other factors such as cost and complex of operation
PROPOSED METHOD
In this method,we are using the fibre optic displacement sensor to discriminating between different teeth surfaces.
ABSTRACT
There has been a large increase in the number of tooth colored restorations “white fillings” placed in recent years.
An increased demand from the public for more aesthetic dental restorations causes a potential problem for forensic dentists who may find the fillings difficult to identify and hence include in postmortem odontograms.
This has implications for the accuracy of dental identifications, particularly in situations where limited time is available for postmortem identification, e.g., mass casualty incidents.
we introduce a simple intensity modulated fiber optic displacement sensor as a quantitative technique for various dental applications.
The intensity modulated based sensors use the modulation of light power transmitted between the head of the sensor and the target surface.
The sensor is capable of discriminating between different teeth surfaces.
Such results are useful as guidelines for tooth surface related researches such as tooth surface profiling and measurement of tooth surface roughness.
