Clinical Trial Summary
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.
Description:
According to the criteria determined in our study, 30 individuals were repeated with their
mouths open for 15 seconds, 1 minute, 2 minutes, 3 minutes, and 5 minutes with a camera, MDP
device, and the use of these devices with a cross-polarization filter to determine how
dehydration will affect the tooth color. For white balance calibration, all the shots will be
taken the same way with the gray reference card, and the color measurements of the teeth will
be taken with two different spectrophotometers in the determined parameters. After these
measurements, patients will be kept with their mouths closed and tooth color measurements
will be taken after 30 minutes and 60 minutes of remineralization. The patients will be
called again 24 hours after these procedures the final color measurement will be made and the
basic color parameters will be recorded. Spectrophotometric images will be analyzed according
to the manufacturer's instructions. The spectrophotometer shall be calibrated and used
according to the manufacturer's instructions before each measurement set. In restorative
dentistry clinical applications, color selection errors, which are irreversible errors caused
by the color changes of the teeth due to dehydration, will be determined in detail in a short
time due to dehydration in the teeth, as a result of this clinical study, and with the result
of rehydration, the color change levels will be determined in detail. return will be
determined. In this way, it is aimed to create a clearer template for physicians based on
time in terms of color selection in the clinic. It is aimed to avoid the need for renewal and
avoid unnecessary sessions, as color harmony can be achieved in restorations made by
considering the color changes of the tooth during dehydration and rehydration periods.
Different photographic techniques and colorimeters will also help measure color variations.
In addition, the sensitivity of the color detection methods used in our study will be
evaluated comparatively, ensuring which method gives more accurate and reproducible results
in clinical applications.
