Attrition, Eruption, and the Periodontium

Abstract

Features of natural masticatory function, of physiological attrition, both occlusal and approximal, and of continuing tooth eruption in adult life need to be borne in mind in considering how the chronic inflammatory periodontal diseases and dental caries have become so widespread. Evidence is reviewed showing that teeth continue to erupt in adulthood, that natural masticatory function prevented plaque accumulation at the approximal risk site of onset of both CIPDs and caries, that epithelial attachment to cementum may be physiological, and that periodontal attachment studies must be age-related.
