JANUARY 29th REMEMBERS QUESTIONS – SMILEY MARLEY
Thank you to the doctor who posted his January 29th 2021 RQs. I have researched the answers and wrote explanations. I hope this
helps. – Smiley Marley
1. Most common tumor of salivary gland
a. Pleomorphic adenoma
b. Mucoepidermoid carcinoma
c. ACC
ANS: A. Most common benign salivary gland tumor both major/minor is pleomorphic adenoma. Mucoepidermoid
carcinoma is the most common malignant tumor of major/minor salivary gland (dental decks).
2. Most common region to get tumor
a. Parotid gland
b. Minor salivary gland
c. hard palate
d. Others
ANS: Most common site for major salivary gland neoplasms is parotid.
3. Half-life of heparin
a. 60 - 90 mins
b. 24 hrs
c. 72 - 96 hrs
ANS: Half-life of heparin is 60-90 minutes
4. Retention in amalgam
a. Parallel mesial and distal walls
b. Parallel occlusal and gingival walls
c. Occlusal and gingival grooves
d. Others
ANS. Parallel mesial and distal walls to avoid undermining the enamel at the marginal ridge.
Amalgam retention form is BL walls converge and retention grooves.
Resistance form in amalgam is bevel, flat floor and rounded internal line angles.
5. Unsupported enamel can be left on
a. Class 3 restoration of composite
b. Class 5 occlusal wall for amalgam
c. Others
ANS: Unsupported enamel can be left on a class 5 occlusal wall because it is not a bearing surface
, 6. Xray to identify idk either it was a dorsum of tongue or soft palate of image of ramus
7. Bone of extraction socket and interdental crest
a. Cortical
b. Cancellous
c. Others
ANS: Cortical. The bone of the tooth socket is a dense cortical plate into which the principal fibers of the periodontal
ligament are inserted, referred to as Sharpey's fibers. Alveolar bone (in both maxilla/mandible) consists of two plates of
cortical bone separated by spongy (cancellous) bone.
8. TAD attached to what
a. Cortical bone
b. Cancellous bone
c. Others
ANS: TAD attaches to cortical bone. Alveolar bone (in both maxilla/mandible) consists of two plates of cortical bone
separated by spongy (cancellous) bone.
Apical migration of the Epithelial attachment with corresponding recession of the marginal gingiva results
in
(a) A shallow sulcus
(b) Gingival pocket formation
(c) lnfrabony pocket formation
(d) Periodontal pocket formation
ANS: Whenever there is attachment loss, there is periodontitis aka periodontal pocket formation.
9. Least important for inlay
a. Margins in enamel
b. Occlusal divergence
10. A patient with facial lancerating pain. What nerve is affected:
a. Glossopharyngeal nerve ! swallowing, gag reflex
b. Hyoglossus nerve ! motor function of tongue (except palatoglossus, vagus nerve)
c. Other
d. Third branch of the 5th cranial nerve **
, 11. 8 yrs. Old boy present to your office with # 8 broken 3 mm with clear pulp exposure and still
bleeding. What is the treatment option?
a. Pulp cap
b. Pulpotomy
c. Apexogenesis
d. Apexification
ANS: apexogenesis
Pulp Cap = if exposure is more than 1mm pulp cap is contraindicated
Apexification = treatment of a non-vital tooth with incomplete apex formation & pulp exposure using calcium hydroxide (or
MTA) to achieve apical closure. Want to create an apical barrier in a necrotic tooth with an open apex…barrier is form 3-6
months… then proceed with root canal treatment
12. Which of these angles decrease with growth?
a. SNA
b. SNB
c. ANB
d. Y- AXIS
ANS: SNA AND SNB increase throughout growth. ANB decreases. ANB = SNA-SNB …. Remember
SNB is mandible which grows more than maxilla so its obvious mathematically that ANB would
decrease over time
13. Which of the following is associated with EBV
a. Burkitt Lymphoma
b. Kaposi Sarcoma
c. Aphthous
d. GERD
ANS: EBV is associated with Burkitt’s Lymphoma, nasopharyngeal carcinoma, and hairy leukoplakia (in AIDS patients).
14. Which surfaces create interferences in non- working side:
a. Lingual planes of buccal inferior cusps and buccal planes of lingual superior cusps.
b. others
ANS: A. Move your jaw to simulate it and see the answer.
, 15. Kid with erythema?
a. First grade
b. Second grade
c. Third grade
d. None
16. Know about KVP
- penetration
ANS: Kilovoltage peak… higher voltage = stronger x-rays = more penetration
17. Not the same but similar photo. How do you describe this lesion?
But the question was: what's the cause of this- i think the pic was leukoplakia and the answer make sense was
premalignant cells
Through the bloodborne pathogen standard, the occupational safety and health administration
directs activity for each of the following except one. Which one is the exception?
a. Using barrier techniques
b. Using material safety data sheets
c. Obtaining hepatitis B vaccines
d. Communicating hazards to employees
e. Performing housekeeping
ANS: B… OSHA requires use of MSDS but does not provide it… manufacturer must provide the MSDS.
Mosby’s say OSHA regulates use of PPE, requirement of hepatitis B vaccines, sterilizing/disinfection, training/
communicating hazards to employees.
OSHA requires the chemical manufacturer, distributor or imported to provide MSDS for each hazardous chemical to
communicate information.
19. After applying Local anesthesia, the patient became bluish with headache, dizziness, shortness of breath,
nausea, poor muscle coordination, and blue-colored skin?
a. Syncope
b. Methemoglobinemia
c. Others
ANS: Methemoglobinemia is most commonly caused by prilocaine. 2nd most common local anesthetic to cause this is
articaine.
