EndodonticsRadiographically, it is virtually impossible to definitively distinguish a granuloma from a cyst. A granuloma consists of inflamed granulation tissue without an epithelial lining, whereas a cyst must have an epithelial-lined lumen. Histology remains the "gold standard" for diagnosis.

Physiology
Answer: 2) Facilitates gluconeogenesis and lipolysis
Explanation: Cortisol, a glucocorticoid hormone, plays a key role in the fight-or-flight response by mobilizing energy stores. It stimulates gluconeogenesis in the liver and promotes lipolysis in adipose tissue, increasing the availability of glucose and fatty acids for energy production during stressful situations.

Physiology
Answer: 1) Decreased heart rate
Explanation: In the heart, acetylcholine acts on muscarinic receptors, which are present on the sinoatrial (SA) and atrioventricular (AV) nodes. This leads to a decrease in heart rate by slowing the sinoatrial (SA) node's automaticity and increasing the time it takes for an electrical impulse to pass through the AV node.

ProsthodonticsExplanation: Implant-supported prostheses have the advantage of maintaining alveolar bone due to osseointegration. This helps preserve the natural bone structure and reduces the risk of bone resorption that is common with traditional complete dentures, which can lead to changes in the patient's facial profile over time.

ProsthodonticsWhen replacing all missing maxillary incisors with PFM restorations, both canines and first premolars should be used as abutments. The four missing incisors create a large span requiring additional support beyond just the canines. Including the first premolars provides better force distribution, stability, and reduces stress on individual abutments, improving long-term prognosis.
