Food impaction occasionally occurs in interproximal sites even though the contacts are tight. In this study of 14 patients with food impaction involving tight contacts, the lack of adequate food escape grooves was common to all 14 sites. Uneven marginal ridges and prominent opposing cusps were less common and, together, made up slightly more than half of the contact sites. An occlusal adjustment technique to create adequate food escape grooves, as well as reduce prominent opposing cusps and correct uneven marginal ridges, completely eliminated food impaction in all but one site. This site achieved an 80% reduction in food impaction. Based on the results of this retrospective study, the lack of adequate food escape groves in teeth adjacent to a contact point manifesting food impaction appears to be the primary factor. Creating food escape grooves adjacent to the marginal ridges eliminates, or nearly eliminates, food impaction in tight contact sites.
