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.

The transitional phase of dentition refers to the period when the primary (deciduous) teeth are being replaced by permanent teeth. This phase is characterized by the simultaneous eruption of permanent teeth and the exfoliation (loss) of primary teeth. It typically occurs between the ages of 6 and 12 years. The other options do not accurately describe this transitional phase; option 2 refers to a post-transitional phase, while option 3 pertains to orthodontic treatment rather than a specific phase of dentition.

Mutually protective occlusion should not be employed in Class II malocclusion (due to posterior interferences), posterior crossbite (due to altered guidance), and Class III malocclusion (due to anterior interference patterns). These conditions prevent proper canine guidance and group function, making mutually protective occlusion inappropriate and potentially harmful to the prosthesis and supporting structures.

Agranulocytosis is a condition characterized by a dangerously low number of granulocytes (a type of white blood cell), including neutrophils. The patient in the problem presents with a total leukocyte count of 1000 ?L, which is significantly low (normal range is typically 4,000 to 11,000 ?L). The differential count specifically reveals severe neutropenia, which is the hallmark of agranulocytosis. The recurrent sore throat attacks are a common symptom due to the compromised immune system's inability to fight off infections.
