DSE COMPREHENSIVE STUDY GUIDE 2026
FULL QUESTIONS AND SOLUTIONS
GRADED A+
◍ Best initial treatment for maxillary oroantral fistula?- antibiotics- irrigation-
gauze pack- two of the above.
Answer: two fo the above: antibiotics and irrigation
◍ Identify:- mucocele- ranula- fibroma- papilloma- thermal injury- SCC- cold
sore (herpes).
Answer: - mucocele - bluish, swollen salivary gland- ranula - mucocele but
on the floor of the mouth- fibroma - benign scar-like reaction to constant
irritation/trauma- papilloma - wartlike lesion; likely positive hx of HPV-
thermal injury - hx of hot food/drink; sudden occurence- SCC - shallow,
ulcerated lesion- cold sore (herpes)
◍ Coronal portion of canine broken, what do you do? - conservative endo, post
and core- immediate extraction- composite build up.
Answer: conservative endo, post and core
◍ Permanent teeth eruption sequence.
Answer: Got it!
◍ What does intrinsic factor do?- allows iron to bind to hemoglobin- prevents
destruction on RBCs- required for absorption of vit B12 from food.
Answer: Required for the absorption of vitamin B12 from food
◍ Patient presents with jaundice. Name three possible causes?.
Answer: cirrhosisHep AHep C
◍ Before trimming teeth on stone cast for immediate denture you must...-
mark a line 3mm above the free gingival margin- nothing- survey the
, remaining teeth.
Answer: mark a line 3mm above the free gingival margin
◍ Question stem describes an epulis in a denture patient., photo included How
would you treat? - apply tissue conditioner- leave alone- prescribe
antibiotics- excision.
Answer: excision
◍ On axiUm's perio chart, what is "FGM-CEJ" ?.
Answer: Recession
◍ The most important treatment for ANUG is?- antibiotics: chlorohexidine
rinse- debridement- patient understanding the importance of oral hygiene-
explaining to the patient the link between oral health and systemic health.
Answer: debridement - take away the disease causing factor. educating the
patient is important too
◍ After placement of an immediate denture, how long should you wait to do a
lab reline? - anytime- 1 week- 6 months- 1 year.
Answer: 6 months- allow tissue healing; conditioning/in office soft relines
can be done any time
◍ Hypoadrenalism is known as?- Cushing's- Addison's- Grave's.
Answer: Addison's- bronzing of the skin, pigmentation in the oral cavity
◍ Orthodontic appliance on maxillary arch, over palate. Wires contacting
lingual of teeth and palate. What is the appliance doing?- lingualizing the
teeth- alignment- tipping the teeth- palatal expansion.
Answer: tipping the teeth - the image makes it obvious that the appliance is
applying pressure to the lingual surfaces of the teeth, which will not create
palatal (boney) expansion, but will allow for tipping of the teeth
◍ If there is a red and white lesion, which do you biopsy?- only the red
portion- only the white portion- red and white portions of the mixed lesion-
none of the above.
Answer: both red and white portions
, ◍ Minimum height for posterior crown preps- 1-2mm- 2-3mm- 3-4mm-
4-5mm.
Answer: 3-4mm
◍ Recognize vertical bone loss radiographically and on perio chart.
Answer: On perio chart: In interproximal area, one surface of a tooth will
have much deeper probing depth than other tooth
◍ Panoramic with black dots and lines that are not related to anatomy. what
could have caused this?- movement- static electricity- improper developer
solution.
Answer: static electricity
◍ Space between mandibular premolar and molar in an older patient, #3, #31,
and #32 are not present, #30 slightly supraerupted and barely in occlusion
w/ distal #4. Why is there is a space? - mesially drifting premolars-
malignant growth- occlusal scheme.
Answer: likely caused by mesially drifiting premolars?- this one is hard to
visualize... but knowing this is an older patient makes you think mesial drift
** This is what other Quizlets say, but radiographically there is no evidence
of anterior crowding if there was mesially drifting premolars. #30 is slightly
tipped distally and supraerupted; the occlusal scheme (lack of occlusion due
to missing #3) may have caused the space
◍ Mandibular incisor with a large pulp chamber and PARL. What caused the
enlarged chamber? - external resorption- dentinogenesis imperfecta- trauma
soon after eruption- osteogenesis imperfecta.
Answer: trauma soon after eruption
◍ Tooth #14 had a RCT and patient is symptomatic with radiolucency in one
of the canals. How do you treat it?- retreat that one canal- retreat all the
canals- retrograde fill the canal with radiolucency.
Answer: retreat all canals
◍ Worst cement for a deep restoration?- Glass ionomer- zinc phosphate-
composite resin- RMGI.
