Automatic Tooth Color Tester Device


Teeth have a very meaningful function for humans which is to help chew, cut food. Therefore the teeth must be treated properly. Although treatment has been done but there are still changes in tooth color. This device can reduce human error from medical officers who conduct examinations. Besides these things, this device is also very useful for determining the colors of teeth in accordance with existing parameters. In this module the average percentage of errors in the color of white teeth is + 2.32%, the color of yellow teeth is + 2.53%, while the color of brown teeth is + 2.34%, and the Ua value of the measurement results is 0.01 while the U95 value is 0.04. From the results of voltage measurements on the colors of yellow and brown teeth there is the same voltage, this is due to differences in the thin color of the teeth, the measurement position of the reading and selection of sensors and the light source used.
