Dental Materials
Stimulates the production of reparative dentin.
What does calcium hydroxide do?
Its purpose is to keep food from packing between teeth and to help stabilize the dental arches.
What are contact areas?
These are the two types of alloy particles.
What are lathe cut and spherical?
The percent of phosphoric acid within etchant.
What is 32-40%?
This is an added for safety when placing a rubber dam.
What is tying floss around the clamp for?
It chemically bonds directly to enamel, dentin, cementum, and stainless steel
What is glass ionomer?
The cells that form enamel rods.
What are ameloblasts?
This is the reaction between the alloy and the mercury which produces a hard and durable metallic restoration.
What is amalgamation?
The type of retention between the tooth and the bonding agent, etched enamel and resin tags that interlock.
What is mechanical retention?
This is the complete intercuspation of the opposing teeth independent of condylar position.
What is Intercuspal position (ICP)
or maximum intercuspation (MIP)?
Soothes pulpal tissue and may be used as a base or temporary filling.
What does zinc oxide eugenol do?
Consists of cementum, periodontal ligaments, and alveolar process.
What it the attachment apparatus of the periodontium
Involves removing marginal irregularities, defining anatomical contours and smoothing in the surface roughness of the restoration.
What is finishing an amalgam?
These components make up composite resin.
What are Resin Matrix (BIS-GMA) and Inorganic Fillers?
It's functions are to adapt the band to the cervical region of the tooth and to separate the teeth to ensure proper contact.
What is the function of a wedge?
These materials adversely effect the curing process of composite.
What are copal varnish and zinc oxide eugenol?
Formed when two triangular ridges extend across the surface of posterior teeth.
What is a transverse ridge?
This produces a drier mix, lacks mercury, and lacks cohesiveness to the mass when it is placed, also reduces amalgam strength.
Undertrituration
The layer of composite exposed to oxygen that does not polymerize.
What is the air inhibited layer?
These cases are the two exceptions to the Rules of Occlusion, where leaving articulating paper marks even in shape and size as those on the natural tooth are not the goal.
What are incisal edge restorations and temporary fillings?
calcium hydroxide, copal varnish, zinc phosphate, amalgam
What is the correct placement order of materials for restoring a deep amalgam restoration?
Lingual lobe of anterior teeth. Makes up the bulk of the cervical third of the lingual surface.
What is a cingulum?
The percentage of amalgam that is silver, which combines easily with mercury.
What is 41-71%
This material is hydrophilic and therefor excellent at finding and absorbing the moisture in the dential tubuals.
What is a primer?
will also accept Priming AND Bonding liquid.
NOTE: bonding agents are hydrophobic when not mixed with a primer.
This part of the Tofflemire matrix retainer is: a threaded rod containing a pointed tip, which can be moved through the entire length of the retainer to secure or loosen the band in the vice.
