What does the term "occlusion" refer to in dentistry?

The term "occlusion" in dentistry specifically refers to the way teeth align and come together when the mouth is closed. This concept encompasses not only how the teeth fit together, but also the relationships between the upper and lower teeth. Proper occlusion is crucial for efficient biting, chewing, and overall oral function. It also plays a significant role in jaw health and can influence the wear and tear on teeth and dental restorations. Understanding occlusion is fundamental for dental practitioners as it affects treatment planning for various procedures, including orthodontics, restorations, and the management of temporomandibular joint (TMJ) disorders.

The other choices pertain to separate aspects of dental care: scaling and polishing involves cleaning procedures for maintaining dental hygiene; the removal of decay is a restorative procedure; and while the alignment of the jaw during chewing is related to occlusion, it does not encompass the full definition, which is primarily focused on the interrelationships of the teeth themselves when the mouth is closed.
