Oral Medicine
The most sensitive diagnostic test for hyperparathyroidism is the measurement of serum intact parathyroid hormone (iPTH) levels. Elevated iPTH levels in the context of hypercalcemia are indicative of primary hyperparathyroidism. However, serum calcium levels are also typically high in this condition and are commonly measured in the initial workup.

Oral SurgeryA pathological fracture occurs when a bone breaks in an area weakened by disease, such as cancer, osteoporosis, or infection. Unlike traumatic fractures, which result from an external force, pathological fractures occur due to underlying conditions that compromise the structural integrity of the bone.

Tetracycline is often prescribed for juvenile periodontitis (also known as aggressive periodontitis) due to its effectiveness against the specific bacteria involved in the condition, such as Aggregatibacter actinomycetemcomitans.

Dental Materials
Electralloy is an alloy of electrolytic gold and calcium, typically with a calcium content of 0.1-0.5%. The addition of calcium creates a dispersion-hardened material that is stronger than pure gold. This property makes it suitable for use in restorations requiring increased hardness and wear resistance, such as inlays and onlays.

Oral SurgeryNeedle breakage is a rare complication in local anesthesia, but it is most likely to occur during a mandibular nerve block (specifically, the inferior alveolar nerve block). This is because it involves a longer needle insertion into deeper tissues, closer to bone, increasing the risk of the patient suddenly moving or the needle bending and snapping at the hub.

Community Dentistry"Sullage" refers specifically to the waste water generated from sinks, baths, and kitchens that does not contain human waste. "Sewage" includes waste that may contain pathogens and is typically discharged from toilets. Thus, kitchen waste water is more accurately described as sullage.

Oral SurgeryHemophilia requires specific management prior to emergency extraction due to the severe bleeding disorder. Patients need factor replacement therapy (Factor VIII in Hemophilia A, Factor IX in Hemophilia B) before any surgical procedure to prevent life-threatening hemorrhage. Other conditions listed don't require such urgent pre-surgical intervention.
