Which of the following premalignant conditions has the highest potential to become malignant?
Which of the following contains all three germ layers?
# Which of the following contains all three germ layers?
A. Teratoid cyst
B. Hamartoma
C. Dermoid cyst
D. Sebaceous cyst
The correct answer is A. Teratoid cyst.
In 1955, Meyer updated the concept of dermoid cyst to describe three histological variants, that is, the true dermoid, epidermoid and teratoid cyst. True dermoid cysts are cavities lined with epithelium with keratinization and skin appendages in cyst wall. Epidermoid cysts do not show skin appendages.
The lining of teratoid cyst varies from stratified squamous to a ciliated respiratory epithelium containing derivatives of ectoderm, mesoderm and endoderm.
Teratoid cyst rarely arises in the head and neck region, in the oral cavity; these cysts occur in the area of the floor of the mouth and may also occur on the tongue, lips, buccal mucosa or the interior of the bone.
What is not included in the measurement of the facial angle?
# What is not included in the measurement of the facial angle?
A. Facial height
B. Frankfort horizontal plane
C. Nasion point
D. Pogonion point
The correct answer is A. Facial height.
The facial angle is used to measure the degree of retrusion or protrusion of the lower jaw. This is the
inferior inside angle in which the facial line (nasion-pogonion) intersects the Frankfort horizontal
(FH). The mean reading for this angle is 87.8 degrees (SD, 3.6) with a range of 82 to 95 degrees. A prominent chin increases this angle, whereas a smaller than average angular reading suggests a retrusive chin.
Therefore, the facial angle indicates the degree of recession or protrusion of the mandible in relation
to the upper face at the point in which the Frankfort horizontal is related to the facial line (nasion-pogonion). The magnitude of this angle increases with a prominent chin.
Non surgical treatment for pericoronitis
Sometimes, the gingival tissue over your third molar teeth may become inflammed because of bacterial infections or food lodgement under the gums. The condition is very painful and may need extraction of third molar tooth or operculectomy for definitive management. However, for those patients unwilling to have their tooth extracted, conservative treatment with medication can be done for 1-2 episodes before they are ready to have the offending tooth extracted.
These medicines should be used for complete 5 days and consultation with registered doctor should be done before taking these. If you are allergic to penicillins and its congeners, these should not be taken. Stop the drug immediately and visit the emergency if you develop any rashes, difficulty in breathing after taking medicines.
