Dental Material Vocab Flashcards
Base/Catalyst
A substance that increase the rate of a chemical reaction without undergoing any permanent chemical change.
Compressive Stress
Compressive stress is the stress of materials that leads to a smaller volume.
Corrosion
The process of corroding metal, stone, or other materials
Council on Dental Materials, Instruments, and Equipment
Sets regulations and standards that all dental materials and what not must meet. Sub division of ADA
Dimensional Change
Change in the mold; Shrink or growth
Direct
In the mouth
Exothermic Reaction
An exothermic reaction is a chemical reaction that releases energy by light or heat
Galvanism
Electricity produced by a chemical reaction. Two metals touch in the mouth
Hardness
A quality or condition of being hard. Resistance to scratching
Heavy body
More viscous. Thicker, applied in tray
Imbibition
Imbibition is a process where water is absorbed by solids or colloids. Swelling
Indirect
Not in the mouth
Light body
Less viscous. Applied in syringe
Luting
Liquid clay or cement used to seal a joint, coat a crucible, or protect a graft
Malleable
Easily influenced using force or pressure
Mechanical properties
Not chemically bonded . Ledge to prevent filling from leaving Mouth
Percolation
Movement of a fluid between tooth and restoration. into an open margin
Primary Consistency
Less viscous, flows easily. Luting. Can be drawn into a 1 inch strand. That is how you can tell if it is done.
Retention
In dentistry, a passive period following treatment when a patient is wearing an appliance or appliances to maintain or stabilize the teeth In the new position
Means by which a material is held together
Secondary consistency
A Thick, putty-like, condensable material that can be rolled into a ball or rope, suitable for use as a base
Sheer strength
Sliding side to side
Solubility
Rate of a material to dissolve in a material
Syneresis
Shrinkage from the loss of water
Tensile Strength
The resistance of a material breaking under tension(pulling/stretching)
Thermal Conductivity
A measure of the ability of a material to allow for the flow of thermal energy from one substance to another
Thermal Sensitivity
Sensitivity to heat in the tooth. Reacts to a heat stimulus
Viscosity
Resistance to liquid to flow
Wettability
Ability to flow.
Yield Point
The material property defined as the stress at which a material begins to deform. Point where material shows strain
