Etiology • Defined as a physiologic wearing of teeth secondary to normal
function/mastication • Can involve all surfaces of teeth including interproximal,
incisal-occlusal, buccal, and lingual • Abnormal occlusal-incisal relationship can predispose to accelerated rates of attrition
Clinical Presentation • Primary and permanent dentitions can be affected. • Flattened occlusal surfaces and reduction of incisal height • The loss of interproximal tooth surface (usually enamel only)
leads to gradual dental arch shortening.

Clinical Presentation • Primary and permanent dentitions can be affected. • Flattened occlusal surfaces and reduction of incisal height • The loss of interproximal tooth surface (usually enamel only)
leads to gradual dental arch shortening.
Diagnosis • Characteristic appearance • Generally proportional to age
Treatment • Usually does not require specific management • Elective restoration of occlusal/incisal surfaces to prevent over-
closure of jaws in function
Prognosis • Excellent
