Dental materials--what goes where? Class I and II cavities.

Unlabelled: Dental amalgam has helped maintain dental public health in the developed world for over a century. However, its days appear to be numbered.

Clinical Relevance: The majority of practitioners carry out large numbers of Class I and II restorations, so an appraisal of the pros and cons of the alternatives may assist in decision-making.
