NDHCE EXAM 2025 QUESTIONS AND
ANSWERS
How often should a child with a transitioning dentition be prescribed radiographs? - ANS 6-
12 months for high caries risk or if caries are visible clinically
12-24 months if caries risk is low
how often are radiographs recommended for adults with no clinical caries and/or low risk for
caries? - ANS 24-36 months
what is the disadvantage to boil and bite mouth guards? - ANS most do not cover all
posterior teeth
what is the most reliable evidence that disease has stopped? - ANS bleeding on probing
what is a class II malocclusion - ANS MB cusp of the max 1st molar is in front of the buccal
groove of the mand 1st molar
what is a class III malocclusion - ANS MB cusp of the max 1st molar is behind the buccal
groove of the mand 1st molar
describe a class I furcation - ANS curvature of the concavity can be detected with the probe
tip but it cannot enter the space; no radiolucency on rads

,describe class II furcation - ANS probe penetrates into the furcation, but does not completely
pass through to the other side; slight radiolucency on rads
describe class III furcation - ANS probe passes through completely through the other side;
radiolucency usually visible from rads
describe class IV furcation - ANS 4
clinically visible because of recession and probe passes through; larger radiolucency
describe ASA 1 - ANS healthy with no systemic conditions or allergies
describe ASA 2 - ANS mild systemic diseases
(controlled hypertension, mild obesity, pregnancy, allergies etc)
describe ASA 3 - ANS severe systemic disease
(poorly controlled hypertension, morbid obesity, chronic renal failure)
describe ASA 4 - ANS severe systemic disease that are a constant threat to life
(liver failure, unstable angina)
describe ASA 5 - ANS patients who are not expected to survive more than 24 hours

, where is perimolysis most seen on patients with bulimia? - ANS palatal of max anteriors
Cyclosporine (Sandimmune)
+ side effect - ANS anti-rejections agent for patients who underwent an organ transplant
side effect is gingival hyperplasia
what types of drugs does xerostomia normally occur? - ANS anti-hypertensive (diuretics,
anti-depressants and anti-psychotics)
cyclic neutropenia - ANS inherited disorder characterized by a decrease in the number of
circulating neutrophils
period lasts 2-3 days and during the pt experiences severe periodontal disease such as
inflammation, ulceration, attachment loss and bone loss
should be treated when neutrophil count is normal
what is trendelenburg position? - ANS head is lower than feet
indicated for syncope
describe a class I caries lesion - ANS extends less than halfway through the thickness of
enamel
describe a class II caries lesion - ANS extend more than halfway through the thickness of
enamel, but dont involve the DEJ
describe a class III caries lesion - ANS extend through DEJ toward the pulp
