style="font-size:10.0pt">: Nowadays, color matching is one of the most challenging issues in dental restorations and cosmetic dentistry. As natural teeth have a wide range of colors, the proportionality of restoration or prosthesis to the remaining teeth, especially in the anterior region, is important. This study was conducted with the aim of comparing two digital devices in determining the color of ceramic samples based on the reference system of spectroradiometry.</span></span></span><br> <span style="font-size:12pt"><span new="" roman="" style="font-family:" times=""><b>Materials and Methods</b><span style="font-size:10.0pt">: </span><span style="font-size:10.0pt"><span style="color:black"><span style="letter-spacing:-.15pt">This laboratory experimental study was performed on 48 ceramic samples of A1, B1, C1, and D2 feldspathic ceramics, with six disks of each color, according to the Vita classic shade guide with a diameter of 0.12&plusmn;0.5 mm and a thickness of 2&plusmn;0.5 mm. Each of the three digital devices, Vita Easyshade, 3Shape TRIOS3, and CS2000, were calibrated according to the manufacturer&#39;s instructions before starting work. In this color evaluation, each ceramic sample was matched with the reference system of CS2000 based on l, a, and b values. Then, ceramic samples were color matched with Vita Easyshade and 3Shape TRIOS3 devices based on CIE lab and Vita classic. The difference in color determination by the three digital devices compared to the reference system was evaluated by SPSS version 26 software and chi-square test (p<0.05).</span></span></span></span></span><br> <span style="font-size:12pt"><span new="" roman="" style="font-family:" times=""><b>Results</b>:<span style="font-size:10.0pt"> <span style="color:black"><span style="letter-spacing:-.05pt">The 3Shape TRIOS3 group had a 66.7% error rate, while the VITA Easyshade V group had a 25% error rate. The difference in the false measurement rate between the two methods was significant (p<0.005), and using the 3Shape TRIOS3 device increased the chance of error by 2.667 times (O.R=2.667).</span></span></span></span></span><br> <span style="font-size:12pt"><span new="" roman="" style="font-family:" times=""><b>Conclusion</b>: <span style="font-size:10.0pt"><span style="color:black"><span style="letter-spacing:-.05pt">Determining color with the VITA Easyshade V device is better and more accurate than determining color with the 3Shape TRIOS3 device.</span></span></span></span></span><br> <br> &nbsp; اسپکترو رادیومتر, هماهنگی رنگ, تمام سرامیک Spectroradiometer, Color coordinate, All-ceramics 166 173 http://jrds.ir/browse.php?a_code=A-10-1786-1&slc_lang=fa&sid=1 Reza Nahidi رضا ناهیدی 100319475328460020322 100319475328460020322 Yes Azad Islamic University گروه آموزشی پروتز،دانشکده دندانپزشکی آزاد اسلامی تهران،تهران، ایران نگین مشکسار 100319475328460020323 100319475328460020323 No دانشجوی دندانپزشکی، دانشکده دندانپزشکی آزاد اسلامی تهران،تهران،ایران لعیا یعقوب نژاد 100319475328460020324 100319475328460020324 No ۲-دانشجوی دندانپزشکی، دانشکده دندانپزشکی آزاد اسلامی تهران،تهران،ایران مریم فرخزادی 100319475328460020325 100319475328460020325 No
