Abstract
In this study, a tooth-imaging system, in which there is a digital camera used as the acquisition device, was developed to measure tooth colour and various uncertainties in the measurement were investigated, including validity of the LED light source (drift over time and colour rendering ability), accuracy and precision of the characterisation model, influence of variation in the distance from subjects to camera in tooth-imaging trials and drying effects of teeth during image capture. This research was to establish the major source of error in tooth-imaging trials and also to reduce measuring errors as mush as possible to optimize the performance of the tooth-imaging system in practical use.
