Parathyroid hormone (PTH) is the primary hormone involved in the regulation of phosphate homeostasis. It acts to increase serum calcium levels and decrease serum phosphate levels by promoting calcium reabsorption and phosphate excretion in the kidneys and stimulating the release of calcium from bones.

Endodontics10-15% carbamide peroxide is the most frequently used agent in home-applied vital bleaching techniques. This concentration is preferred because: 1) It provides effective bleaching with minimal sensitivity, 2) Safe for unsupervised home use, 3) Releases approximately 3-4% hydrogen peroxide slowly over several hours, 4) Good balance between efficacy and safety, 5) Allows for overnight application. Higher concentrations like 35% hydrogen peroxide are used only in-office under professional supervision due to potential tissue damage.

Acute necrotizing ulcerative gingivitis (ANUG) is characterized by painful, bleeding gums, ulceration of the interdental papillae, and bone loss. Pocket formation is a feature of chronic periodontitis, not typically ANUG, as the acute necrosis leads to a loss of tissue rather than the formation of deepened gingival pockets.

The RAS gene produces a
protein (Ras) that acts as a molecular switch in cell signaling
pathways, typically promoting cell growth and proliferation when
bound to GTP (guanosine triphosphate). To
turn this signal off, the Ras protein must hydrolyze its bound GTP
to GDP (guanosine diphosphate). This
hydrolysis is significantly accelerated by GTPase activating
proteins (GAPs), which inhibit the active state of the Ras
protein by promoting its deactivation.

A measure that has validity is necessarily reliable, as reliability
is a prerequisite for validity. However, a measure that is reliable does not
necessarily mean it is valid. Validity refers to the degree to which a
measurement tool accurately measures what it is intended to measure. Reliability
is the consistency of the results produced by the tool.

Prosthodonticsguiding planes are flat, polished surfaces on the abutment teeth that guide the RPD along a specific path during insertion and removal. They are located adjacent to the edentulous area and are crucial for the proper seating and function of the denture.

PeriodonticsMast cells contain granules rich in histamine and heparin. Histamine is a vasoactive amine that is released during allergic reactions and inflammatory processes, causing vasodilation and increased vascular permeability.
