The author discusses the epidemiology, etiology and prevention of non-cariogenic cervical lesions. From a retrospective epidemiological survey in which participated 50 subjects, mean age 44 years, ensues that important etiological factors include: excessive intake of exogenous acids poor technique of tooth brushing and overburdening of teeth as a result of parafunctions or inadequate state of static and/or dynamic occlusion. The incidence of lesions increases with the patient's age and is maximal during the fourth and fifth decade. Most frequently the first premolars are affected and combined lesions predominate. Based on the epidemiological survey the author recommended principles of primary and secondary preven- tion. In clinical practice it is suitable to use a classification of lesions according to their appearance: dish-shaped, grooved, combined lesion and wedge-shaped defect. The classification is easy for the attending physician, is instructive and points indirectly to etiological factors participating in their genesis.
