Wound tissue and repair

# The word 'Patient' is derived from Latin word 'patiens' which means:
A. Disease
B. Suffering
C. Treatment
D. To cure

# "Sign of compression" is characteristically seen in:
A. Lipoma
B. Hernia
C. Vascular swelling
D. Sebaceous cyst

MCQs on Cardiopulmonary Resuscitation and Airway Maintenance

# The primary airway hazard for an unconscious patient in a supine position is:
A. Tongue obstruction
B. Bronchospasm
C. Laryngospasm
D. Aspiration

# Among the following, which is the rescue breathing in adult?
A. 6 times/min
B. 18 times/min
C. 12 times/min
D. 24 times/min

MCQs on Respiratory System Part 2

# Localised suppuration of lung is called:
A. an abscess
B. Empyema
C. Emphysema
D. Anasarca

# Not true about Pleurisy:
A. Pleural pain
B. Pleuropericardial rub
C. Usually secondary to lung infection
D. None of the above

Rapid Palatal Expansion

# Typically rapid palatal expansion is done with a jack screw that is activated at the rate of:
a) 1.0 to 2.0 mm/week
b) 1.0 to 2.0 mm/day
c) 0.5 to 1.0 mm/week
d) 0.5 to 1.0 mm/day   

The correct answer is D. 0.5 to 1.0 mm/day. 

Rapid expansion typically is done with two turns daily of the Jackscrew (0.5mm) activation. This creates 10 to 20 pounds of pressure across the mid palatal suture, which is enough to create microfractures of interdigitating bone spicules. In slow palatal expansion, approximately 0.5mm per week is the maximum rate at which the tissues of the midpalatal suture can adopt.

Best space maintainer

# Best space maintainer is: 

a) Active space maintainer

b) Passive space maintainer 

c) Band and loop 

d) Pulpotomised primary tooth

     

The correct answer is D. Pulpotomised primary tooth.

Natural tooth if preserved by endodontic treatment is the best space maintainer because it provides easiness and more patient compliance and doesn't affect the eruption of the succedaneous tooth.

Respiratory System MCQs Part 1

# Pulmonary surfactant is:
A. Lecithin
B. Dipalmitoyl Phosphatidyl choline
C. Dipalmitoyl Phosphatidine serine
D. Sphingosine

# Heimilch Maneuver is carried out in:
A. Syncope
B. Airway obstruction
C. Carotid blow out
D. Cardiac arrest

Ideal Orthodontic Tooth Movement

# Resorption in case of ideal orthodontic tooth movement should be:
a) Undermining
b) Indirect
c) Frontal
d) Necrotic     

The correct answer is C. Frontal. 

Application of light orthodontic forces will result in frontal/ direct resorption. Frontal resorption occurs only when the forces applied are close to the capillary pressure, i.e. 20 -26 gm/ sq. cm of root surface area. 

Oppenheim and Schwarz have been given credit for discovering the optimum orthodontic force levels usually light continuous forces are recommended for tooth movement.
