Where Ito and Itend are the intensities
at the beginning and end of the curves. The time of maximum change
(tmax) was calculated by taking the derivative of the
dehydration curve (dI/dt) and identifying the position of maximum
change.
The purpose of this study was to develop and test a more effective
clinical SWIR dehydration probe for use on occlusal surfaces and develop
improved methods for analysis of the acquired dehydration curves that
most effectively differentiate active from arrested lesions.
