Since dentistry is considered both as an art and science subject therefore, the aim of science of dental materials is to stress upon the principles involved in the use of dental materials. The main requirements for dental materials in general are as under:
Why materials react and behave as they do?
What manipulative techniques are used?
How variation in techniques effect their properties?
What is the effect of material on its environment?
What is the nature of the interface between the synthetic material and oral tissues?
What is the effect of oral environment on the material?
Proper evaluation & testing of the material is required before application
It is emphasized that most manufacturers of dental materials should operate appropriate quality assurance programs so that the materials are thoroughly tested and evaluated before release into the market
