Chapter 3 KEY TERMS, GROUP 8 Flashcards
Thixotropic fluids
liquids that flow more readily under mechanical force
Direct restorative materials
restorations placed directly into a cavity preparation
Indirect restorative materials
materials used to fabricate restorations outside the mouth that are subsequently placed into the mouth
Malleability
the ability to be compressed and formed into a thin sheet without rupture
Ductility
the ability of an object to be pulled or stretched under tension without rupture
Mixing Time
the amount of time allotted to bring the components of a material together into a homogeneous mix
Working Time
the time permitted to place and manipulate the material in the mouth
Initial Set Time
the time at which the material can no longer be manipulated in the mouth
Final Set Time
the time at which the material has reached its ultimate state
Dual Set Materials
materials that polymerize when the materials is initiated by exposure to a blue light source and then continue with a chemical set reaction
Viscosity
Resistance of liquid to flow
Mechanical properties
Physical properties seen when load or force is applied to material
Hardness
Resistance of penetration, wear & abrasion
Shelf-life
Length of time a material can be stored before it becomes improper to use
Bio-Aerosols: Splatter
Complex aerosols created by procedures. Can be airborne for minutes to hours
