Interproximal
Relating to the contact surfaces between adjacent teeth, particularly the areas where neighbouring teeth meet.
Full Definition
The interproximal space is the region between the contact areas of adjacent teeth, including the interdental papilla and the proximal tooth surfaces themselves. The term is used extensively in descriptions of caries location, restorative work, and hygiene instruction. Editors should distinguish it from 'interdental', which refers more broadly to the space between teeth rather than the surfaces. 'Interproximal' is consistently written as a single unhyphenated word in contemporary dental literature. It frequently appears as a modifier, as in 'interproximal caries' or 'interproximal brush'.
Usage
Usage note: Do not hyphenate; 'inter-proximal' is an outdated form that should be silently corrected in modern clinical copy.
