What is quadrant of the mouth?

In dentistry, the mouth is divided into four quadrants for the purpose of organizing and describing dental treatments and procedures. Each quadrant is identified by a number and corresponds to a specific region of the mouth. Here are the four quadrants of the mouth:

1. Upper Right Quadrant:

- This quadrant includes the upper teeth on the right side of the mouth, starting with the upper right central incisor and extending back to the upper right third molar.

2. Upper Left Quadrant:

- This quadrant includes the upper teeth on the left side of the mouth, starting with the upper left central incisor and extending back to the upper left third molar.

3. Lower Right Quadrant:

- This quadrant includes the lower teeth on the right side of the mouth, starting with the lower right central incisor and extending back to the lower right third molar.

4. Lower Left Quadrant:

- This quadrant includes the lower teeth on the left side of the mouth, starting with the lower left central incisor and extending back to the lower left third molar.

The quadrant system helps dentists communicate precisely about which tooth or area of the mouth is being referred to during examinations, treatments, and record-keeping. It also allows for efficient documentation and accurate billing for dental procedures performed in each quadrant.
