Oral MedicineGingival manifestations, such as gingival enlargement (gingival hyperplasia or infiltration) and bleeding, are most frequently and severely associated with acute myeloid leukemia (AML). The infiltration of leukemic cells into the gingival tissues is a characteristic feature of some subtypes of AML, particularly the monocytic and myelomonocytic types.

Oral PathologyMyositis ossificans would NOT cause pathologic fractures of maxilla or mandible because it involves ossification within muscle tissue, not weakening of existing bone structure. Bone cysts, multiple myeloma, and giant cell tumor all cause bone destruction and weakening, predisposing to pathologic fractures. Myositis ossificans actually adds calcified tissue rather than destroying bone.

ProsthodonticsBefore altering the abutment contour for clasp retention, it is essential to establish the guiding planes. This is done by disking the proximal surfaces of the abutment teeth to create a flat, smooth surface that will guide the RPD during insertion and removal. Once the guiding planes are in place, the contour of the abutment can be altered to accommodate the placement of the retentive elements such as rests and minor connectors.

EndodonticsMicroabrasion for removal of local stains on teeth utilizes 18% hydrochloric acid. This technique involves: 1) Application of 18% hydrochloric acid mixed with pumice to create an abrasive paste, 2) The acid etches the enamel surface while pumice provides mechanical abrasion, 3) This removes superficial enamel layer containing stains (typically 25-200 micrometers), 4) Effective for fluorosis stains, white spot lesions, and superficial discolorations. The procedure requires careful isolation and neutralization to prevent tissue damage.

NEETMDSLoss of taste sensation on the affected side is not a feature of unilateral hypoglossal nerve damage because the hypoglossal nerve (cranial nerve XII) is a motor nerve that controls the muscles of the tongue and does not carry taste fibers.

ProsthodonticsThe most common reason why hyperplastic tissue is removed or reduced during the construction of a complete denture is that it interferes with the stability of the denture.

NEETMDSEpinephrine (adrenaline) is a critical treatment for anaphylaxis due to its alpha-1, beta-1, and beta-2 adrenergic effects. It causes vasoconstriction, increases heart rate and contractility, and causes bronchodilation. The standard dose for an adult in an emergency setting is 0.5 mg of a 1:1000 concentration solution administered intramuscularly (IM) or subcutaneously (SC). Intravenous (IV) administration of the 1:1000 concentration is generally too potent and can cause severe adverse effects, requiring a much more dilute solution (1:10,000 or 1:100,000) and careful titration, usually only in a hospital setting.
