Dental materials used in the dental profession are indeed many, varied, and complex. The dental specialist who prepares and uses many of these materials in assisting the dental officer must know their composition, properties, uses, and manipulation.

A thorough knowledge of dental materials and the skill to manipulate these materials is one of the important duties of a dental specialist.
