Oral PathologyCorticosteroids are the drug of choice in facial nerve palsy (Bells palsy), especially when initiated within 72 hours of onset. Corticosteroids reduce inflammation and edema of the facial nerve within the narrow facial canal, improving recovery outcomes. Vitamin A and anti-inflammatory drugs are not first-line treatments for facial nerve palsy.

Microbiology
The main tool for the detection of "cases" of tuberculosis is 1.
Sputum examination. Sputum examination: This is the primary method for
diagnosing active pulmonary tuberculosis. Sputum samples are collected and
examined for the presence of Mycobacterium tuberculosis through
microscopy (e.g., acid-fast bacilli staining) and culture methods. It is
considered the gold standard for confirming active TB cases. Mantoux test: Also known as the tuberculin skin test,
this test is used to determine if a person has been exposed to the
tuberculosis bacteria. However, it does not diagnose active TB; rather, it
indicates whether a person has been infected with the bacteria at some
point. Chest X-ray: While chest X-rays are important for
identifying lung abnormalities associated with tuberculosis and can support
the diagnosis, they are not definitive for detecting the bacteria itself.
They are often used in conjunction with sputum examination.Explanation of Each Option:

Although overcrowding can contribute to impaction, it is not a
direct cause. The most common causes of impaction are insufficient space in the
dental arch and abnormal angulation of the tooth due to the presence of other
teeth or abnormal growth patterns. Genetic factors also play a significant role
as the size and shape of the jaw are inherited traits.

General MicrobiologyWhile recombinant hepatitis B vaccines are produced using various methods, cloning the HBsAg gene in E. coli is not one of them. Instead, the gene is typically cloned in yeast or insect cells to produce the surface antigen for the vaccine.
