How is the mouth divided into sections?

The mouth is divided into sections primarily by quadrants, which helps dental professionals effectively identify and treat specific areas of the oral cavity. Each quadrant corresponds to a fourth of the mouth, allowing for a systematic approach to dental examinations, diagnosis, and treatment.

The division into quadrants (upper right, upper left, lower right, and lower left) simplifies communication among dental staff and enhances clarity when referring to specific sections during procedures or discussions about patient care. This division is essential for organizing dental charts and for identifying areas that may require attention, such as extractions, cavities, or periodontal treatment.

While arches refer to the two main dental arches (maxillary and mandibular) that hold the teeth, and regions can describe broader anatomical areas, the usage of quadrants provides a more precise and practical method for navigating the mouth in a clinical setting. Lobes are more relevant to the structure of individual teeth, especially in terms of their development and anatomy, rather than the overall organization of the mouth.
