Definition 1 of 109
Hardest to softest:
Glass ionomer > calcium hydroxide > zinc oxide eugenol
Order the 3 different liners from hardest to softest:
calcium hydroxide
zin oxide eugenol
glass ionomer
Pros and cons of polishing amalgam
What is the difference b/t overhang and flash on restorations?
Who is Acidulated Phosphate Fluoride best for?
Term 2 of 109
GV Black's caries Class IV
Same as Class III, but also involves incisal edges
>> mesial, distal, incisal of ANTERIOR teeth
surgical procedure performed by dentist to expose more tooth structure to later restore
the tooth prosthetically
-Mesial & Distal of premolars
-Mesial & Distal of molars
-Incisal edges of anterior teeth + Occlusal surfaces of posterior teeth, that have been worn
away due to abrasion
,Term 3 of 109
What is the difference between a Hard Pack and a Soft Pack?
-Overhang: excess amount of restoration caused by improper placement of matrix band
and wedge
-Flash: thin ledge of restorative material that extends beyond the restoration
Both are Zinc Oxide, but
-Hard: has Eugonal
-Soft: NO Eugonal
Clove oil
Interferes with polymerization composites
-can pass through skin
-endocrine disruption
-irritating to skin and eyes
-toxic to aquatic organisms
-consumer products can promote bacterial resistance
Term 4 of 109
___ is the best material for Class V restorations
Gold
Composite
Amalgam
Ceramic
Term 5 of 109
T/F
You give fluoride first, then you etch
True
False
,Definition 6 of 109
+No prosthetic connections for bacteria to grow on >> better gum health
+white color >> aesthetic
+only destroyed by decay unlike ceramic crowns (which, if parts come off, can leave sharp edges)
Criteria for good temporary crown
What is tarnish?
Advantages of Zirconia
Properties of a good periodontal dressing
Term 7 of 109
What is a cavity liner used for?
Engineered materials made from 2 or more constituent materials with significantly different
physical and chemical properties and which remain separate and distinct within the finished
structure
surgical procedure performed by dentist to expose more tooth structure to later restore
the tooth prosthetically
Protects pulpal tissue by:
-covering pulp from irritation of new filling
-kill bacteria
-promote growth of secondary dentin
-acts as base for filling
1) contains highly concentrated fluoride in a resin
2) varnish (for desensitizing + caries prevention)
, Term 8 of 109
When do you expose yourself and your patient to the highest amount of Mercury?
While applying fluoride varnish to prevent decay
During routine dental cleanings with ultrasonic scalers
When taking x-rays of the patient's teeth
When removing or replacing amalgam restorations
Term 9 of 109
Parts in composite resin material and what they are for
1) Chemical cure: self cure (2 paste system, limited working time)
2) Light cure: most common in layers, lots of working time
3) Dual cure: 2 pastes: light starts but finishes chemically
Trituration = the production of a homogeneous material by mixing component materials
thoroughly
-Used to prepare Amalgam for it to get hard
surgical procedure performed by dentist to expose more tooth structure to later restore
the tooth prosthetically
-Fillers (strength + hardness)
-Resin matrix (liquid portion, holds everything together)
-Silicone coupling agent (connects filler and matrix agents)
-Pigments (color)
-Initiators (polymerization)
-Accelerator (speeds up polymerization)
