When a mouth is divided into fourths, the parts are referred to as?

When the mouth is divided into fourths, the sections are referred to as quadrants. This terminology is widely used in dentistry to help in the identification and treatment of specific areas within the mouth. Each quadrant corresponds to one-fourth of the mouth: the upper right, upper left, lower right, and lower left sections. Understanding this division is crucial for dental professionals when it comes to planning treatments, conducting examinations, and communicating clearly about patient care.

The other terms, while related to dentistry, refer to different concepts. The term "arch" generally refers to the entire dental arch, encompassing either the upper or lower row of teeth. "Sextant" is used to describe a division of the mouth into six parts, which is more specific and not relevant when discussing the standard four divisions. "Posterior/Anterior" describes the location of teeth relative to the front (anterior) and back (posterior) of the mouth but does not pertain to the division of the mouth into fourths.
