Clinical aspects of the tooth-coloured restorative materials... 

A restorative material can be used for the aesthetic restoration of the front (anterior) teeth only if it is as translucent as tooth enamel. This is because colour matching depends on translucency as well as hue and chroma. 

This chapter is concerned with the essential classification of the materials used to repair teeth and restore their function. As far as direct restoratives are concerned, we follow the classification on Mount et al. [1] and consider that the two basic types of modem tooth-coloured materials are the composite resins and the glass-ionomer cements. They are fundamentally different, and though hybrids have been attempted, combining their advantages is not feasible for sound scientific reasons. 

As we have seen, in the classification of tooth-coloured dental restorative materials, the composite resins represent one of the major types [1,6], The other major type is the glass-ionomer cement.
