Sponsor's own description
Dental restorations should mimic sound tooth structures in terms of color and optical properties especially in the anterior region. However, closely matching natural teeth with a restoration can be one of the most challenging procedure in restorative dentistry. Shade matching includes color determination, color communication with dental lab and color reproduction with dental restoration for indirect techniques or color determination and selection of the appropriate material and application method when using direct techniques. Therefore color selection is the first critical step in the restoration procedures and should be carried out properly. Color determination must be carried out before any of the restorative procedures, isolation or impression. Most of the dental procedures cause dehydration and increase the opacity of the enamel and teeth appear whiter. Few clinical and in vitro studies evaluated the degree of color change after dehydration and rehydration periods. However, inconsistencies exist between studies in terms of color change degree and duration of return to appreciable values. The aim of the present study was to evaluate the degree of color change in half an hour dehydration period of the teeth and to determine if color return to baseline after half an hour or 24 hours. According to the null hypotheses of the study: * There is no perceptible difference occur after tooth dehydration. * Tooth color will not return to baseline values after half an hour or 24 hours rehydration periods.
