Method and terminal device for managing teeth using oral image

A terminal device, comprising:

• a display unit configured to display a first oral measurement image including tooth measurement images in a tooth shape to measure state information of each of user's teeth;
• a communication unit configured to receive state information of a target teeth of the user measured from a tooth diagnostic device;
• a user interface unit configured to receive a selection signal input for selecting a first tooth measurement image from among the tooth measurement images;
• and
• a controller configured to control to match the state information of the target tooth with state information of the first tooth measurement image, and represent the state information of the first tooth measurement image to be represented in the first oral measurement image,
• wherein the state information of the target teeth is sequentially received by measuring the state information of the target tooth n times,
• wherein, when the state information of the target tooth is matched, worst state information among the state information of the target tooth measured n times is matched with the state information of the first tooth measurement image,
• wherein the first oral measurement image includes first, second, and third measurement image areas,
• wherein upper jaw tooth measurement images corresponding to teeth arranged on an upper jaw of the user among the tooth measurement images are represented in the first measurement image area,
• wherein lower jaw tooth measurement images corresponding to teeth arranged on a lower jaw of the user among the tooth measurement images are represented in the second measurement image area,
• wherein, in the third measurement image area, information related to the target tooth is represented, and
• wherein when the measurement is performed at i times out of the n times, the worst state information among the state information of the target tooth measured at the i times and the state information of the target tooth measured up to the i times is represented in the third measurement image area.
