Exam Questions and CORRECT Answers
All of the following are situations where it is clinically justified to remove an asymptomatic
impacted tooth EXCEPT one. Which is the EXCEPTION?
a) Facilitate orthodontic treatment
b) Potential for development of periodontal defect on the distal surface of the
adjacent second molar (tooth 31)
c) Prevent the development of caries, root resorption, and/or periodontal disease on
adjacent teeth
d) Prevent the possibility of jaw fractures - CORRECT ANSWER - d) Prevent the
possibility of jaw fractures
Removing an asymptomatic impacted tooth to prevent the possibility of jaw fractures is not
typically a clinically justified reason.
A chi-square test was used for statistical data analysis. What is determined using the
chi-square test?
a) Negative correlations
b) Positive correlations
c) The difference between 2 or more percentages of categorical outcomes
d) The difference between 2 means of 2 groups
e) The difference between means of 3 or more groups - CORRECT ANSWER - c) The
difference between 2 or more percentages of categorical outcomes
After analyzing the results of the chi-square test, researchers determined that the
resultant value was high. What does this indicate?
,a) Linear regression needs to be performed
b) The null hypothesis is accepted
c) The null hypothesis is rejected
d) T-test needs to be performed - CORRECT ANSWER - c) The null hypothesis is rejected
In statistical hypothesis testing, a high chi-square test statistic indicates a significant difference
between the observed and expected frequencies in the data. This typically leads to the rejection
of the null hypothesis, suggesting that there is a relationship or association between the variables
being tested.
In this particular study, the chi-square test rejected the null hypothesis. Which of the
following was most likely the null hypothesis for this study?
a) Bupivocaine has inferior duration and degree of effectiveness to the experimental
local anesthetic
b) Bupivocaine has superior duration and degree of effectiveness to the
experimental local anesthetic
c) The experimental local anesthetic has inferior duration and degree of
effectiveness to bupivocaine
d) The experimental local anesthetic has superior duration and degree of
effectiveness to bupivocaine
e) There is no difference in the duration and degree of effectiveness between
bupivacaine and the experimental local anesthetic - CORRECT ANSWER - e) There is no
difference in the duration and degree of effectiveness between bupivacaine and the experimental
local anesthetic
Patient 35 yo F
CC My filling has come out, and im here to have it replaced
History: Tooth 30 had class I composite filling placed 6 months ago
,Findings The patient has a fever of 101.5F, cough, fatigue, anosmia, and headache. The patient's
father, whom she visit 5 days ago, was diagnosed with a
SARS-CoV-2 infection, 2 days ago
Given the patients current findings, what is the most likely next step?
a) Call 911 and inform them the patient may have Sars-CoV-2 infection
b) Follow injection control guidelines during SARC-CoV-2 and treat the patient
c) Refer the patient to a medical facility for Sars-CoV-2 treatment
d) Send the patient home and instruct her to call her physician - CORRECT ANSWER - c)
Refer the patient to a medical facility for SARS-CoV-2 treatment
7) Which test will aid in confirming the presence of acute SARS-CoV 2 infection?
a) Anti-SARS-CoV-2 Reflex IgG
b) Anti-SARS-CoV-2 IgM
c) C Reactive Protein
d) RT PCR
e) RT-PCR and SARS-CoV-2 RNA - CORRECT ANSWER - d) RT PCR
RT-PCR (Reverse Transcription Polymerase Chain Reaction) is the gold standard test for
confirming the presence of acute SARS-CoV-2 infection
If the patient had presented with tooth pain and a need for emergency dental care during
the acute phase of a mild SARS-CoV-2 infection, what would be the most appropriate
next step?
a) Call 911 and inform them the patient may have COVID-19
b) Follow infection control guidelines during COVID-19 and treat the patient
c) Refer the patient to a medical facility
d) Send the patient home and instruct her to call her physician - CORRECT ANSWER - b)
Follow infection control guidelines during COVID-19 and treat the patient
, If the patient presents with tooth pain and requires emergency dental care during the acute phase
of a mild SARS-CoV-2 infection, the most appropriate next step would be to follow infection
control guidelines specific to COVID-19 and proceed with treating the patient. This includes
implementing measures to minimize the risk of viral transmission, such as wearing appropriate
personal protective equipment (PPE), maintaining proper hand hygiene, and ensuring proper
ventilation in the dental office. Treatment should be provided while taking necessary precautions
to protect both the patient and dental staff from potential exposure to the virus.
What does a positive RT-PCR test two weeks after the first positive RT-PCR test indicate about
the acute phase of the illness
a) Complete recovery
b) High chance of re-infection
c) Non-conclusive
d) Partial recovery
e) Re-infection - CORRECT ANSWER - d) Partial recovery
A positive RT-PCR test two weeks after the first positive RT-PCR test indicates that the
individual may still have remnants of the virus in their system. It suggests that the acute phase of
the illness is ongoing or that the individual is in the process of recovering but has not fully
cleared the virus from their body. Therefore, option d) Partial recovery is the most appropriate
interpretation in this context.
Which of the following correctly classifies the genetic material in the SARS-CoV-2 virus?
a) Double-stranded DNA
b) Double-stranded RNA
c) Protein based prion
d) Single-stranded RNA
e) Single-stranded RNA - CORRECT ANSWER - d) Single-stranded RNA
The genetic material in the SARS-CoV-2 virus is classified as single-stranded RNA. This RNA
serves as the blueprint for viral replication and protein synthesis within infected host cells.
Therefore, option d) Single-stranded RNA correctly classifies the genetic material in the SARS-
CoV-2 virus.
