Abstract: The present invention relates to a dental device which detects the color of a damaged tooth and automatically determines the proper restorative dental material to be used to repair the damaged tooth. The device illuminates the tooth with light and detects the various color components of light reflected off the tooth. Signals indicative of the various color components are then processed and compared against known reference signal values indicative of the color of various restorative materials in order to determine which of the plurality of restorative dental materials best matches the color of the tooth. The device then displays a message indicative of the chosen material. The detector is preferably a lightweight, hand-held, battery powered device, which includes a wand assembly which is placed against the tooth. A disposable, replaceable, protective sheath is placed over the wand to ensure the health and safety of the patient. The sheath includes a light absorbing dark material which reduces, and preferably eliminates, the amount of ambient light which is reflected off the tooth and detected by the device when the wand is being used.

Abstract translation: 本发明涉及一种检测损伤牙齿的颜色并自动确定用于修复受损牙齿的适当的修复牙科材料的牙科装置。 设备用光照亮牙齿，并检测从牙齿反射的光的各种颜色分量。 然后对指示各种颜色成分的信号进行处理，并与指示各种修复材料的颜色的已知参考信号值进行比较，以便确定多种修复牙科材料中的哪一种最佳地匹配牙齿的颜色。 然后，设备显示指示所选材料的消息。 检测器优选地是轻量级的手持式电池供电装置，其包括抵靠牙齿放置的棒组件。 将一次性，可更换的护套放置在魔杖上方，以确保患者的健康和安全。 护套包括光吸收暗材料，其减少并优选地消除当使用魔杖时从牙齿反射并被装置检测到的环境光的量。
