The condition involved with an unerupted tooth or impacted tooth is:

 # The condition involved with an unerupted tooth or impacted tooth is:
A. Dentigerous cyst
B. Mural ameloblastoma
C. Adenomatoid odontogenic tumor
D. All of the above


The correct answer is D. All of the above.

Dentigerous cyst is always associated initially with the crown of an impacted, embedded or unerupted tooth. A dentigerous cyst may also be found enclosing a complex compound odontoma or involving a supernumerary tooth. The most common sites of this cyst are the mandibular and maxillary third molar and maxillary cuspid areas.

Adenomatoid Odontogenic Tumors are seen in a rather narrow age range, between 5 and 30 years, with most cases appearing in the second decade. Females are more commonly affected than males. Lesions often appear in the anterior portion of the jaws, more often in the anterior maxilla, generally in association with the crowns of impacted teeth. 

HSV-2 virus resides in:

 # HSV-2 virus resides in:
A. Basal ganglia
B. Stellate ganglia
C. Lumbosacral ganglion
D. Otic ganglion



The correct answer is C. Lumbosacral region.

It is now well established that the HSV does not remain latent at the site of the original infection in the skin or oral mucosa. Instead, the virus reaches nerve ganglia supplying the affected areas, presumably along nerve pathways, and remains latent there until reactivated. The usual ganglia involved are the trigeminal for HSV-1 and the lumbosacral for HSV-2. Viral DNA can be demonstrated in these ganglia. Unfortunately, this incorporation of viral DNA into host DNA ensures a lifelong infection beyond the reach of antibody, cell mediated immune responses or chemotherapy.

The tongue of a patient deviates to one side whenever he sticks his tongue out. The cranial nerve that may be damaged is:

 # The tongue of a patient deviates to one side whenever he sticks his tongue out. The cranial nerve that may be damaged is:
A. Trigeminal nerve
B. Vagus nerve
C. Facial nerve
D. Hypoglossal nerve



The correct answer is D. Hypoglossal nerve.

HYPOGLOSSAL NERVE
Hypoglossal nerve is the twelfth cranial nerve. It supplies the muscles of the tongue. The hypoglossal nerve is tested clinically by asking the patient to protrude his/her tongue. Normally, the tongue is protruded straight forwards. If the nerve is paralysed, the tongue deviates to the paralysed side. 

Which of these is a pseudocyst?

 # Which of these is a pseudocyst?
A. Nasolabial cyst
B. Globulomaxillary cyst
C. Traumatic cyst
D. Radicular cyst



The correct answer is C. Traumatic cyst.

Traumatic cyst is also called as Solitary bone cyst, hemorrhagic cyst, extravasation cyst, unicameral bone cyst, simple bone cyst, idiopathic bone cavity. The traumatic cyst is a pseudo cyst (lacks an epithelial lining) and an uncommon lesion comprises about 1% of all jaw cysts. It occurs in other bones of the skeleton as well.

Which type of ameloblastoma appears to be aggressive with a marked proclivity for recurrence?

 # Which type of ameloblastoma appears to be aggressive with a marked proclivity for recurrence?
A. Follicular ameloblastoma
B. Plexiform ameloblastoma
C. Granular cell ameloblastoma
D. Acanthomatous ameloblastoma




The correct answer is C. Granular cell ameloblastoma.

Granular cell ameloblastoma is aggressive with a marked proclivity for recurrence. Follicular has highest recurrence rate (29%) with lowest for acanthomatous (4%). If 'aggressive' is asked, 'Granular cell ameloblastoma' is the answer, if only recurrence is asked, 'follicular ameloblastoma' is the answer.

Which is the only inorganic general anesthetic in use?

 # Which is the only inorganic general anesthetic in use? 
a. Ether. 
b. Chloroform. 
c. Nitrous oxide. 
d. Cyclopropane. 



The correct answer is C. Nitrous oxide.

It is a colourless, odourless, heavier than air, noninflammable gas supplied under pressure in steel cylinders. It is nonirritating, but low potency anaesthetic; unconsciousness cannot be produced in all individuals without concomitant hypoxia; MAC is 105% implying that even pure N2O cannot produce adequate anaesthesia at 1 atmosphere pressure. Patients maintained on 70% N2O + 30% O2 along with muscle relaxants often recall the events during anaesthesia, but some lose awareness completely.
