[Possibilities of testing the biological acceptability of composite filling materials, with special reference to the microscopic test for pulp vitality. Review of the literature].
The main problem of microscopically observing the living pulpa consists in that it lies embedded into hard tissue. The haemodynamics of the pulpa may be defined by studying the physical parameters by examining the characteristics of blood flow and by the factors determining them. By comparison with other tissues little work is dealing with regulating the blood flow. The vital microscopic model of the rat incisor pulpa was first employed by Gängler to testing dental filling materials. The results thereof well complete the findings of standardized tests. On basis of the foregoing the sublining in case of clinical employment of composite filling materials is unconditionally suggested.
