[Some new points of view of cavity form].

Abstract

The discovery of new data about the anatomy and physiology of the dental tissues, the improvement of the diagnostics of dental caries and the development of stomatological materials and technique are preconditions for a change of some concepts for the preparation of the cavities and their form. A new trend in cavity preparation is discussed on the base of literature data, characterized by maximum sparing of the hard dental tissues and a change in some of the geometric characteristics of the cavity form but the basic requirements for the biological and technical expedience remain unaltered.
