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

Quantitative Evaluation of the Effect of Dehydration and Rehydration Levels on Tooth Color Using Various Measurement Techniques

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.

Study Overview

• Status: Enrolling by invitation
• Conditions: Tooth Discoloration
• Intervention / Treatment: Diagnostic test: Mobile Dental Photography; Diagnostic test: Mobile Dental Photography with cross-polarization filter; Diagnostic test: Mobile Dental Photography with gray reference card; Diagnostic test: Mobile Dental Photography with cross-polarization filter and gray reference card; Diagnostic test: Digital Camera; Diagnostic test: Digital Camera with cross-polarization filter; Diagnostic test: Digital Camera with cross-polarization filter and gray reference card; Diagnostic test: Digital Camera with gray reference card; Diagnostic test: Rayplicker; Diagnostic test: Rayplicker with gray reference card; Diagnostic test: Vita Easyshade; Diagnostic test: Vita Easyshade with gray reference card

Detailed 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.
