Occlusal
Pronunciation: ok-LOO-zul
Relating to the biting or chewing surface of posterior teeth, or to the contact between upper and lower teeth.
Full Definition
The term 'occlusal' refers to the biting surface of posterior teeth (premolars and molars) where opposing teeth make contact during chewing. It is also used more broadly in relation to occlusal analysis (the study of how teeth meet), occlusal radiographs, and occlusal adjustments. In clinical notes, it appears as a tooth surface notation (e.g., O in charting shorthand for a cavity on that surface). Editors must not confuse the surface-specific meaning with the broader functional meaning, both of which are valid in different document contexts.
Usage
Usage note: For anterior teeth, the equivalent surface to 'occlusal' is 'incisal' (the cutting edge). Do not apply 'occlusal' to incisors or canines without clinical justification.
