what is the property of a material that allows it to not impede or adversely affect living tissue?
what are the materials used to reconstruct tooth structure?
what is the force applied to compress an object?
what is the force applied in opposite directions to stretch an object?
what is the force applied when two surfaces slide against each other or in a twisting or rotating motion?
what is the internal force, which resists the applied force?
what is the distortion or deformation that occurs when an object cannot resist a stress
what is the bending caused by a combination of tension and compression?
what is a fracture resulting from repeated stresses that produce microscopic flaws to grow?
what is a material's ability to maintain its position without displacement under stress?
what is susceptible to being dissolved?
what is the ability to absorb moisture?
what is the deterioration of a metal caused by a chemical attack or electrochemical reaction with dissimilar metals in the presence of a solution containing electrolytes (such as saliva)
what is the discoloration resulting from oxidation of a thin layer of a metal at its surface. It is not as destructive as corrosion
what is an electrical current transmitted between two dissimilar metals?
a change in the size of matter. For dental materials this usually manifests as expansion caused by heating and and contraction caused by cooling
the measurement of change of volume or length in relationship to change in temperature
coefficient of thermal expansion
movement of fluid in the microscopic gap of the restoration margin as a result of differences in the expansion an contraction rates of the tooth and the restoration with temperature changes associated with ingestion of cold or hot fluids or foods
the rate at which heat flows through materials
materials having low thermal conductivity
the production of heat resulting from the reaction of the components of some materials when they are mixed
the act of sticking two things together. In dentistry, it is used to describe the bonding or the cementation process. Chemical adhesion occurs when atoms or molecules of dissimilar substances bond together and differs from cohesion in which attraction among atoms and molecules are like materials hold them together
to connect or fasten, to bind
the ability of a liquid to wet or intimately contact a solid surface. Water beading on a waxed car is an example of poor ______
the ability of a liquid material to flow
the minimum thickness obtainable by a layer of a material. It is particularly important to dental cements
the electrical charge that attracts atoms to a surface
the space between the walls of the preparation and the restoration
leakage of fluid and bacteria caused by microscopic gaps that occur at the interface of the tooth and the restoration margins
the color of the tooth or restoration. It may include mixtures of colors such as yellow brown
the intensity or strength of a color
how light or dark a color is. A low _____ is darker and high _____ is brigher
light passing directly through an object
optical property in which light is completely absorbed by an object
varying degrees of light passing through and being absorbed by an object
