MOCK INBDE SET2 EXAM 2025
QUESTIONS AND ANSWERS
What is the mode of action of occlusal sealants?
a) They are bactericidal to S. mutans
b) They increase the pH at the site of S. mutans growth
c) They interrupt bacterial succession
d) They remineralize enamel
e) They eliminate the habitat for S. mutans - ANSWER✔✔-e) They eliminate the habitat
for S. mutans.
Occlusal sealants act as physical barriers that cover the pits and fissures of teeth,
creating a smooth surface that prevents food debris and bacteria, particularly
Streptococcus mutans, from accumulating in these areas. By eliminating the habitat
where bacteria can colonize and produce acids, occlusal sealants help reduce the risk of
dental caries.
,Which condition does the patient most likely have if her oral cavity displays chloasma
of
the gingiva?
a) Asthma
b) Melanoma of the palate
c) Oral infection
d) Pregnancy
e) Seizure disorder - ANSWER✔✔-d) Pregnancy
Chloasma, also known as melasma, is a condition characterized by dark patches on the
skin, often caused by hormonal changes, especially during pregnancy. When this occurs
in the oral cavity, particularly on the gingiva, it's most likely associated with hormonal
changes during pregnancy.
Patient Male, 52 years old
CC "I am here to get implants."
Background Past medical Hx:
● Severe dental caries
● Type 2 diabetes mellitus
,● Hypertension
● Blood sugar level and BP controlled with medication
Current MEdications:
● Metformin
● Pioglitazone
● Amlodipine
● Enalapril
NKDA
a) As per the conventional loading protocol, how long does the patient have to wait
before the prosthesis can be attached to the implants?
i) 1-2 hours
ii) 1-3 days
iii) 14 days
iv) 3 weeks
v) 4-6 months - ANSWER✔✔-v) 4-6 months
All of the following are true for osteoradionecrosis EXCEPT one. Which one is the
, EXCEPTION?
a) All patients who require ext in a previously irradiated bone are at a risk
b) It may be spontaneous or result from trauma
c) The non-healing bone may become secondarily infected
d) This condition occurs in 30-40% of patients - ANSWER✔✔-d) This condition occurs
in 30-40% of patients.
Osteoradionecrosis is a severe complication of radiation therapy, especially in the head
and neck region. However, the incidence of osteoradionecrosis is generally lower than
stated in option d. While the exact incidence varies. The actual incidence tends to be
lower, estimated around 5-15% in the literature.
Patient Female, 48 years old
CC "A tooth in the back of my mouth on the right side hurts all the time."
Background Past medical Hx:
● Type 2 diabetes
● Obesity
Current Medications:
● Metformin
