Dental composite resins are types of synthetic resins which are used in dentistry as restorative material or adhesives. Synthetic resins evolved as restorative materials since they were insoluble, aesthetic, insensitive to dehydration, easy to manipulate and reasonably inexpensive. Many dentists today use resin fillings instead of amalgam fillings. Composite resins are also used for reshaping teeth, partial crowns, and to adhere retainers.

Dental materials ranging from composite resin fillings, to porcelain to metal crowns and bridges, to alginate impression material, to dental adhesives for bonding and restorative dentistry are all tested for their mechanical property strengths. ISO 6872, ISO11405, ISO14801, ISO 9917, and other standards specify the requirements and the corresponding test methods to access dental materials.
