Description

Technical Field

[0001] The utility model relates to the technical field of dentistry, in particular to a tooth root apex locator. Background Art

[0002] When doing root canal treatment, a hole is first made on the end face of the tooth, and then a root canal preparation machine is used to clean the pulp and dental nerve in the root canal. When the preparation machine cleans the root apex of the root canal, the pulp and dental nerve will remain, causing symptoms such as dental nerve pain in the later stage of root canal treatment. When the preparation machine cleans the root apex of the root canal, the root canal file will pierce the gums, causing gum congestion or inflammation. Therefore, it is particularly important to use the apex locator in root canal preparation.

[0003] When doctors measure the root apex, they need to connect the root measuring line to the root apex locator. The traditional root apex locator has a unique interface for connecting the root measuring line, so the direction of the line is fixed. When placed on the work surface, the direction of the line may be inconvenient for doctors to operate. The display screen of the traditional root apex locator is often fixed. When details need to be displayed, there is often only a single horizontal screen or a single vertical screen, and it is even more impossible to switch between horizontal and vertical screens.
