- C.
Malar Rash
- D.
Gothic Disease
Correct Answer
A. Primary Herpetic Gingivostomatitis -ex) herpes labialisExplanation
Primary Herpetic Gingivostomatitis, also known as herpes labialis, is the correct answer because it is a viral infection that causes inflammation and sores in the mouth and gums. This condition is typically caused by the herpes simplex virus type 1 (HSV-1) and is characterized by symptoms such as fever, sore throat, swollen lymph nodes, and painful blisters or ulcers in the mouth. Secondary Herpetic Gingivostomatitis is a recurrent form of the infection, while Malar Rash and Gothic Disease are unrelated conditions.Rate this question:

- D.
All of the above
Correct Answer
B. Most common oral infection -aka- thrush or moniliasis (many types possible)Explanation
The correct answer is "Most common oral infection -aka- thrush or moniliasis (many types possible)." This is because candidiasis, also known as thrush or moniliasis, is the most common oral infection caused by the Candida fungus. It can manifest in various forms and can affect different parts of the body, including the mouth, throat, and genitals. Treatment for candidiasis may involve excision biopsy in severe cases, but it can also be managed with antifungal medications. Therefore, the statement "Most common oral infection -aka- thrush or moniliasis (many types possible)" accurately describes candidiasis.Rate this question:

A deficiency of the immune response resulting from hypoactivity or decreased numbers of lympnodes
- D.
None of the above
Correct Answer
A. A deficiency of the immune response resulting from hypoactivity or decreased numbers of lymphoid cellsExplanation
Immunodeficiency refers to a condition where the immune response is deficient or weakened. This can be caused by hypoactivity, which means the immune system is not functioning at its optimal level, or by a decrease in the number of lymphoid cells, which are responsible for immune responses. Both of these factors can contribute to a deficiency in the immune response, leading to a compromised ability to fight off infections and diseases.Rate this question:

If melanoma is disseminated at the time of diagnosis (stage 3) the tumor is usually fatal
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
If melanoma is disseminated at the time of diagnosis (stage 3), it means that the cancer has spread beyond the initial site to other parts of the body. This is a more advanced stage of melanoma and is associated with a poorer prognosis. The spread of cancer cells to distant organs or lymph nodes makes it more difficult to treat and control the disease. Therefore, in most cases, when melanoma is disseminated at the time of diagnosis, it is usually fatal.Rate this question:

what is the source of the epithelium associated with a dentigerous cyst ?
- A.
Reduced enamel epithelium
- B.
IEE
- C.
OEE
- D.
Both a & b
Correct Answer
A. Reduced enamel epitheliumExplanation
The source of the epithelium associated with a dentigerous cyst is the reduced enamel epithelium. This is the epithelium that surrounds the enamel organ during tooth development. It becomes reduced and forms a layer around the crown of the tooth after eruption. In the case of a dentigerous cyst, this reduced enamel epithelium becomes trapped around the crown of an unerupted tooth, leading to the formation of the cyst. The IEE (inner enamel epithelium) and OEE (outer enamel epithelium) are also involved in tooth development but are not specifically associated with dentigerous cysts.Rate this question:
