In fact, it is a microscope with light source and lens, which can be roughly adjusted and finely adjusted. Generally, mandibular teeth can be directly seen by light source, while maxillary teeth need to be reflected by oral mirror.

Zeiss oral microscope is commonly used. After connecting the monitor, you can see the details of the teeth directly from the screen. Very good stuff.
