In order to make sure that everyone in the dental field is talking about the same thing, we use a standard method of naming and numbering quadrants.

There are 4 quadrants:

Maxillary Right (quadrant 1)

Maxillary Left (quadrant 2)

Mandibular Right (quadrant 4)

Mandibular Left (quadrant 3)

divided by a midline

Let's see how you do with a question on quadrants: Toggle open/close quiz question

Value: 1
Which quadrant is the mandibular left?


I'm wondering.... did you notice that quadrant 1 starts in the upper right with quadrant 4 ending in the lower right? This quadrant 1 - 4 pattern will actually come into play when we talk about tooth numbering.
