DH 101 Midterm Exam Questions and
Answers

heartbeat - ANS-Fast: tachycardia
Slow: bradycardia
Know the names for the highest and lowest numbers in a blood pressure reading - ANS-
High: systolic
Low: diastolic
Know the reading for a normal blood pressure reading - ANS-119/79
Know the main objective of an extra-oral and intra-oral examination - ANS-to detect oral
cancer at an early stage
maintenance of professional atmosphere
minimal possibility of overlooking an area and missing detail
Increased efficiency and conservation of time of importance
Know when a health history should be updated - ANS-Each time a patient is seen, and
annually
Know the best way to obtain a complete patient history - ANS-a combination of a
questionnaire and interview, provides a quick look at the patients conditions
Know if an antibiotic prophylaxis (pre-med) guarantees to prevent all cases of infective
endocarditis and what kind of maintenance needs to occur to prevent bacteremia -
ANS-No, incidents when ABT permed did not prevent IE following a dental invasive
procedure
Must be taken 1 hr before tissue is manipulated to prevent bacteria
Know how a patient's confidential health history needs to be signed - ANS-In permanent
ink
Know why it is important for a patient to take a pre-med before any type of manipulation
of the gingival tissues - ANS-possibility of creating bacteremia prevent infective
endocarditis
Know what could help a patient show up to their appointment with their pre-med - ANS-
Telephone screening
, What course of action would a clinician take before the appointment if a patient doesn't
remember taking his premed but has a heart murmur and what would the clinician
require before starting treatment on the patient? - ANS-Call the patient's MD or
specialist regarding pre-meds
A written statement regarding the need for the pre-med from the doctor should be
faxed over
List types of questions a clinician would ask a patient if the patient's past history shows
hepatitis - ANS-When it was contracted
Treatment rendered
And the resolution
Name the races that have an increased risk of developing Diabetes - ANS-African
Americans
Native Americans

ANS-15-22 in from clinician's eyes and oral cavity
Know the neutral position of the clinician's shoulders - ANS-Relaxed and parallel with
the hips and flood
Know the main requirement for the development of a carious lesion - ANS-
Microorganisms, fermentable carbohydrate, susceptible tooth surface
Name the 2 types of dental caries described by location - ANS-Pit and fissure; occ pits
of molars and premolars
Smooth surface; no pit, groove or other fault
Know where a root lesion starts - ANS-Gingival recession
Know when Disto-occlusion (Class II) occurs - ANS-Buccal groove of mandibular 1st is
distal to the Mesiobuccal cusp of the maxillary 1st premandibular molar
Match patient facial profiles with the classes of occlusion - ANS-Prognathic: prominent,
protruded mandible and normal (usually) maxilla concave
Mesognathic: Slightly protruded jaws; straight profile
Retrognathic: Prominent maxilla with mandible posterior to normal convex
Know the purposes of the proximal tooth contact - ANS-Proximal tooth contacts serve to
stabilize the position of teeth in the dental arches to prevent food impactions.
Name the man who determined the different classes of occlusion and whose principles
we still use today - ANS-Edward Angle
