DAT 101 FINAL EXAM WITH COMPLETE
SOLUTIONS 100% VERIFIED
what are the components of composite? - ✔✔resin matrix- foundation of matirx, not strong enough to
be used alone fillers- adds strength ( glass, quarts, and silica)
coupling agent- strengthens the resin by chemically bonding the filler to resin
polymerization- - ✔✔process in which the resin material is changed from a soft plastic to a hardened
resstoration by light curing
etching- - ✔✔to cut into a surface by the use of an acid product
etchant - ✔✔the acid solution or gel used to etch tooth structure and remove the smear layer
smear layer - ✔✔very thin ( 5-10 microns) film of organic debris that adheres to dentin as a result of
cavity preperation
finishing - ✔✔use of finishing burs,disk, and polishing strips to smooth composite
when is pin retention needed? - ✔✔used when decay is extensive and there is loss of a cusp
what is an IRM?
when is it used? - ✔✔intermediate restoration for short term placement
when are direct bonded veneers done? - ✔✔used where teeth are damaged or discolored full crown or
porc. veneers are not wanted to close diastemas
adv- less expensive
-short appointment time
DIsadv. - limited life span wear and discolor
have to maintain good hygiene
careful of biting
, Barriers to communication - ✔✔judging ordering avoiding a persons concerns
what % of spoken word is not heard - ✔✔90
what % of people fail at jobs because they do not relate well with people? - ✔✔80
specialties of dentistry - ✔✔oral surgery- diagnosis and surgical treatment of dieases, injuries, and
defects of oral and maxillofacial regions endodontics- cause, diagnoses, prevention and treatment of
diseases and injuries to the pulp ortho- Malocclusions of the teeth and associated structures Prostho-
restoration/ replacement of natural teeth with artificial pediatric- deals with oral care of children perio-
diseases of the oral tissues and supporting and surrounding the teeth
dental public health- deals with developing policies at county state, and national levels for programs to
control and prevent disease oral pathology- deals with the nature of diseases affecting the oral cavity
and adjacent structures
disinfection - ✔✔used in all areas and cannot be covered with barriers
sanitation - ✔✔same as cleaning- does not remove all microorganisms
sterilization - ✔✔all forms of microorganisms are destroyed
cidal = - ✔✔to kill
static/stasis= - ✔✔stop;stand still
hand scrubbing - ✔✔least desirable wear PPE's (utility gloves) only one or two instruments at a time
use long- handled brush air dry or pat dry
some states prohibit hand scrubbing
ultrasonic cleaning - ✔✔loosen and remove debris from instruments wear PPE's (utility gloves)
processed till clean run 10-15 minutes use cleaning solutions that are formulated for the ultrasonic **
ultrasonic doe not disinfect; only removes debris solution discarded daily periodically test the ultrasonic
efficiency
