On the Ethiology and History of Wedge-shaped Defects
- Výzkumný ústav stomatologický, Praha, ředitel doc. MUDr. O. Krejsa, CSc.
The contribution contains an overview of former and current theories concerning the ethiology of wedge-shaped defects. Hypothesis attempting to explain these defects as a result of traumatic occlusion is critised. Based on comprehensive study of documents and archaeological material concerning oral hygiene history, it can be concluded that the appearance of dental hard tissues lesions has always been closely linked with the development of oral hygiene implements and cleaning methods. It seems to be evident that a new type of defect with wedge-shaped profile began to occur, since the toothbrush had been invented and has replaced the implements formerly used.
