FK-5-Cellular and molecular bases of immune and non-immune host defense mechanism-DIAGNOSIS AND TREATMENT PLANNING

A patient presents with painful, recurrent oral ulcerations that have persisted for over a month. Which immunological mechanism is most likely involved in the pathogenesis of these lesions?

During a dental exam, you note several areas of gingival inflammation with bleeding upon probing. An increased presence of which cell type would be expected in the gingival crevicular fluid as an initial response?

A patient reports a history of anaphylactic reactions to certain medications. When planning dental treatment, which immune mechanism should be of primary concern?

In the progression of periodontal disease, which cytokine plays a significant role in alveolar bone resorption by stimulating osteoclast activity?

A dental implant procedure leads to peri-implantitis. Dysregulation of which host defense mechanism contributes to the progression of this condition?

What is the primary concern regarding the immune response during dental treatment for a patient with a history of organ transplantation on immunosuppressive medications?

Which cells are primarily responsible for the adaptive immune response to periodontal pathogens through the production of antigen-specific antibodies?

A patient presents with a localized, fluctuant swelling in the gingival tissue associated with a non-vital tooth. Which host defense mechanism is primarily attempting to contain this infection?

In the context of wound healing following oral surgery, which immune cells play a crucial role in debridement and the transition to tissue repair by releasing growth factors and cytokines?

A patient with a viral infection develops oral lesions with epithelial cell damage. Which immune cells are most likely mediating the destruction of these infected cells?

The effectiveness of a dental vaccine for a specific oral pathogen would primarily rely on stimulating which arm of the immune system?

A patient experiences a delayed allergic reaction to a component of a dental material, manifesting as contact dermatitis around the mouth. Which type of hypersensitivity reaction is most likely involved?

Which non-immune defense mechanism in the oral cavity acts as a physical barrier and contains antimicrobial substances like lysozyme?

During the formation of dental caries, initial demineralization of enamel is facilitated by acids produced by bacteria. Which host immune factor in saliva helps neutralize these acids and inhibit demineralization?

A patient with a compromised immune system due to chemotherapy is at an increased risk of opportunistic oral infections, like oral candidiasis (thrush). This occurs due to a deficiency in which aspect of host defense?

What is the primary role of salivary Immunoglobulin A (sIgA) in oral health?

When treating oral infections with antibiotics, considering the potential for antibiotic resistance is important. Which is a host-related factor that can influence the outcome of antibiotic therapy?

During diagnosis of certain oral lesions, a biopsy is done to examine cellular infiltrate. The predominance of lymphocytes in a chronic inflammatory lesion suggests what type of immune response is involved?

Autoimmunity, where the immune system attacks self-antigens, can manifest in the oral cavity as conditions like Sjögren's syndrome. Which of the following is a key characteristic of autoimmune diseases?

When planning treatment for a patient with a known latex allergy, it is crucial to avoid triggering which immune response?
