Measurement/ ruler in 4.8

Hello
Im a new slicer user, kindly enlighten me.

How can measure distances between two structure ( like measuring the length of a tooth on a CT scan)?

Can someone please provide a link to the tutorial for the same. The documentation provided is too difficult to understand. Is there a module that provides for this specific purpose like drag and drop two points and we get the distance in mm measured?

Thankd

Yes, there is a ruler tool to do exactly what you want to do:
