Allergy to dentrifrices
- B.
Recent dental work in the area which included local anesthesia
- C.
Development of a tumor in the area
- D.
Trauma to the area
Correct Answer
A. Allergy to dentrifricesExplanation
Allergy to dentrifrices is not considered an etiologic factor in the development of necrotizing sialometaplasia. Necrotizing sialometaplasia is a benign, self-limiting inflammatory condition that affects the salivary glands, typically the minor salivary glands in the palate. It is believed to be caused by local ischemia or trauma, such as pressure from dentures or recent dental work. The development of a tumor in the area and trauma to the area are known etiologic factors for necrotizing sialometaplasia. However, there is no evidence to suggest that allergy to dentrifrices plays a role in its development.Rate this question:

Which of the following is not a basic type of inflammation
- A.
Acute
- B.
Chronic
- C.
Granulomas
- D.
Pyogenic
Correct Answer
D. PyogenicExplanation
Pyogenic is not a basic type of inflammation. Acute, chronic, and granulomas are all well-known types of inflammation, characterized by different durations and patterns of immune response. Acute inflammation occurs rapidly and is typically short-lived, while chronic inflammation lasts for a longer duration. Granulomas refer to a specific type of chronic inflammation characterized by the formation of granulomas, which are small areas of immune cells. However, pyogenic is not a recognized type of inflammation and therefore does not fit into the basic types of inflammation.Rate this question:

- C.
Leukocytosis
- D.
Lymphadenopathy
Correct Answer
D. LymphadenopathyExplanation
Lymphadenopathy refers to the enlargement of lymph nodes, which is not considered to be part of the acute phase response. The acute phase response is a systemic reaction to inflammation or infection, characterized by fever, increased cortisol levels in the blood, and leukocytosis. Lymphadenopathy, on the other hand, is a specific local response where the lymph nodes become enlarged due to the accumulation of immune cells to fight off infection or inflammation. While lymphadenopathy can occur as a result of an acute phase response, it is not considered a direct component of the response itself.Rate this question:

Wounds in which edges cannot be closely opposed undergo healing by
- A.
Primary intertion
- B.
Secondary intention
- C.
Tertiary intention
- D.
Scar tissue
Correct Answer
B. Secondary intentionExplanation
Wounds in which edges cannot be closely opposed undergo healing by secondary intention. This means that the wound is left open and allowed to heal naturally from the bottom up, with the formation of granulation tissue and subsequent contraction. This process is typically used for larger, deeper wounds or those with significant tissue loss or contamination. It differs from primary intention, where the wound edges are brought together with sutures, and tertiary intention, where the wound is initially left open and then closed later. Scar tissue refers to the fibrous tissue that forms during the healing process, regardless of the method used.Rate this question:

Infections caused by microorganisms that are not normally pathogenic to a person with a healthy immune system are known as
- A.
Attenuated
- B.
Pathogens
- C.
Opportunistic
- D.
Compromised
Correct Answer
C. OpportunisticExplanation
Opportunistic infections are caused by microorganisms that typically do not cause harm to individuals with a healthy immune system. However, when a person's immune system is compromised or weakened, these microorganisms can take advantage of the opportunity to cause infection. This can occur in individuals with conditions such as HIV/AIDS, cancer, or those taking immunosuppressive medications. In such cases, the immune system is unable to effectively fight off these normally non-pathogenic microorganisms, leading to opportunistic infections.Rate this question:

A type of mircoorganism that can only cause disease after entering and replicating in a host cell is
- A.
Bacteria
- B.
Virus
- C.
Fungi
- D.
Protozoa
Correct Answer
B. VirusExplanation
Viruses are a type of microorganism that can only cause disease after entering and replicating in a host cell. Unlike bacteria, fungi, and protozoa, viruses are acellular and cannot replicate on their own. They rely on host cells to provide the necessary machinery for replication. Once inside a host cell, viruses take over the cellular machinery to produce more virus particles, eventually leading to the destruction of the host cell. This ability to hijack host cells and replicate within them is what allows viruses to cause diseases in humans and other organisms.Rate this question:

Which of these is not one of the three main routes of human disease transmission
- A.
Sexual
- B.
Fecel-oral
- C.
Respiratory
- D.
Animal vector
Correct Answer
D. Animal vectorExplanation
Animal vector transmission is not one of the three main routes of human disease transmission. The three main routes are sexual transmission, fecal-oral transmission, and respiratory transmission. Animal vector transmission refers to the spread of diseases through animals, such as mosquitoes carrying malaria or ticks spreading Lyme disease. While animal vector transmission is an important mode of disease transmission, it is not one of the three main routes mentioned in the question.Rate this question:

Serological testing preformed to diagnose a viral infection most often involves the detection of
- A.
Antibodies
- B.
Toxins
- C.
Genetic material
- D.
Components of the cell wall
Correct Answer
C. Genetic materialExplanation
Serological testing is a diagnostic method that involves the detection of antibodies in the blood to determine if a person has been exposed to a specific virus. Antibodies are produced by the immune system in response to an infection, so the presence of specific antibodies indicates a viral infection. This type of testing is commonly used to diagnose viral infections such as HIV, hepatitis, and COVID-19. Detection of genetic material or components of the cell wall may be used in other diagnostic methods, but serological testing primarily focuses on the detection of antibodies.Rate this question:

A disease control agent that uses live or killed microorganisms or their components to stimulate immune response and create memory is known as
- A.
Antibody
- B.
Antiseptic
- C.
Vaccine
- D.
Antiboitic
Correct Answer
C. VaccineExplanation
A vaccine is a disease control agent that uses live or killed microorganisms or their components to stimulate an immune response and create memory. By introducing a weakened or dead form of a pathogen into the body, vaccines trigger the immune system to produce antibodies and develop immunity against that specific pathogen. This helps prevent future infections and provides long-term protection against the disease.Rate this question:
