Quantitative Evaluation of the Effect of Dehydration and Rehydration Levels on Tooth Color

This study aims to evaluate the dehydration and rehydration changes in teeth over time and the quantitative effect of these changes on natural tooth color in the clinic. In addition, it is aimed to evaluate the effectiveness of different color measuring devices used in color detection in the clinic, the use of cross-polarization filters, and white balance calibration in color evaluation. Clinicians will evaluate the results of the time intervals in which dehydration is effective in detectable levels of color change. Considering the quantitative changes in dehydrated and rehydrated teeth, it will be possible to prevent negative results in restorations.
