title: [The epidemiology of wedge shaped defects].
abstract: 23% of a nonselected group of patients showed wedge shaped defects (9-10 of them per person). The number of teeth with these cervical erosions increases with age. Small accumulation of plaque was found. 65% of the patients with wedge shaped defects had parafunctions and 70% had a chronic pain. A complex of causes underlies the wedge shaped defects. A causal relation appears to exist between wedge shaped defects, occlusal disharmony, parafunctions and strong psychological tension of patients.
