OSCE Dental Hygiene Exam Questions
and Answers Latest Version
When should you first start brushing a child's teeth?
-When the first tooth appears.
Signs and Symptoms of erosion
-dental caries from vomiting
-Perimolysis: erosion from vomiting mostly on the maxillary lingual
surfaces. Raised appearance of restoration margins.
Abrasion
-V-shaped notch in the gingival portion of the facial aspect of the tooth.
-Results from forces of friction between the teeth or external objects.
-Can happen from improper brushing technique or the use of a toothpick or
pipe.
Attrition
-Results from forces between the teeth.
-Wear on the incised and occlusal surfaces from grinding.
Abfraction
-Biomechanical destruction related to fatigue, flexure, and deformation of
tooth structure.
-Can appear as a wedge-shaped lesion at the cervical third of the tooth.
What is the most effective public health measure to prevent tooth
decay?
Community Water Fluoridation
New recommended level of fluoride is?
0.7 ppm
ASA 1

ASA 5
Moribund patient not expected to survive for more than 24 hours without
surgery.
ASA 6
Brain dead pt.
Radiolucency
Dark areas on the film. Produced by less dense structures that allows the
passage of x-rays. (i.e. cysts)
Radiopaque
Light areas on the film. Produced by denser structures. (i.e. Lamina Dura)
Overlap
inappropriate horizontal angulation
Foreshortening
too much vertical angulation
Elongation
not enough vertical angulation
Mark across film
bent film
Circular white boarder on film
Cone cut
Herringbone or waffle pattern on film
backwards film
Darker film with outlines of many teeth
double exposure
Film too dark
too much development time; temperature too high
, Film too light
not enough development time; temperature too low
Cracked emulsion
sudden temperature change between developer and fixer.
Darker areas
developing solution touches film before processing procedure.
Lighter areas
fixer solution touches film before processing procedure.
Yellow/brown stains on film
exhausted solutions or insufficient washing.
Straight white border on film
developer cutoff caused by incomplete immersion of film into developer.
Straight black border
fixer cutoff caused by incomplete immersion of film into fixer.
Outline border of another film
Films stuck together in solutions.
White spots on film
air bubbles trapped during processing.
Thin, black, branchlike lines on film
Static lines caused by low humidity and opening film packet too quickly.
Fogged films
improper safelight, light leaking into dark room, outdated film.
"V" or "Sharks fin" on pano
caused by lead collar.
Exaggerated smile on pano
chin tipped down too far
Flat smile on pano
chin tipped too far up
Mandibular incisors roots blurred on pano
chin tipped too far down
Maxillary incisors roots blurred on pano
chin tipped too far up
One side shows larger teeth/condyle
patient head is twisted (the larger side is the distant side)
White straight opacity
slumping causing ghost image of spine
Shadow over maxillary teeth
tongue not touching rough of the mouth
Anterior teeth thicker and wider
