MICROANATOMY

Detailed explanation-1: -The mouth is divided into four parts called quadrants. The upper part of your mouth contains the first two quadrants, and the lower portion of your mouth contains the third and fourth quadrants. The right upper part of your mouth is the first quadrant, followed by the top left side (second quadrant).

Detailed explanation-2: -The teeth are arranged in the mouth in 2 arches that contain 2 quadrants each (16 teeth in each arch, 8 teeth in each quadrant in the permanent dentition).

Detailed explanation-3: -Quadrants and Sextants An imaginary midline divides each dental arch into mirror halves. The two arches, each divided into halves, create four sections, which are called quadrants (Figure 4-6).
