Digital photograph with Ashur plaque indicatorDigital photographs with the Led lights (365 nm)The QLF (Quantitative Light-Induced Fluorescence- 405 nm) images
Digital photograph with Ashur plaque indicator: Digital photographs will be taken at baseline and post-procedure under the fluorescence light source (Ashur plaque indicator (405 nm). Images will be captured with a Sony Alpha 7iii (Sony, Japan) digital camera equipped with a 90-mm macro lens. Camera settings will be adjusted for the Ashur device (1/125, f/22, ISO 25600). To ensure standardization all images will be captured in a dark room.
Digital photographs with the Led lights (365 nm): Digital photographs will be taken at baseline and post-procedure under the fluorescence light source (Led lights (365 nm). Images will be captured with a Sony Alpha 7iii (Sony, Japan) digital camera equipped with a 90-mm macro lens. Camera settings will be adjusted for the LED lights (1/125, f/22, ISO 8000). To ensure standardization, the LED lights will be stabilized on the flash brackets at a 45° angle on both sides, and all images will be captured in a dark room.
The QLF (Quantitative Light-Induced Fluorescence- 405 nm) images: The images obtained using the QLF (Quantitative Light-Induced Fluorescence- 405 nm) device will be recorded. QLF images will be obtained with its own camera.
Study summary
A cheek retractor will be placed to ensure consistent isolation throughout the procedure. Dehydration will be assessed at baseline, at the 5th minute, and at the 10th minute using three different evaluation techniques. At each time point, digital photographs will be captured under two distinct fluorescence light sources to document changes visually. In addition, fluorescence images will be obtained using the QLF (Quantitative Light-Induced Fluorescence) device to provide objective, quantitative data. All images will be recorded and analyzed digitally to evaluate dehydration-related changes in fluorescence. The aim of our study is to clinically evaluate the changes in the fluorescence properties of natural tooth following dehydration.
