Periodontics
After periodontal surgery, root sensitivity is primarily due to the exposure of dentin tubules (option 1). When the root surface is exposed, the dentin becomes sensitive to stimuli because the tubules can transmit sensations to the pulp.
Exposed cementum (option 2) is less likely to cause sensitivity because cementum is not as innervated as dentin. Formation of plaque (option 3) can lead to sensitivity as it may irritate the surrounding tissues and contribute to inflammation.

General Medicine
The heat-labile toxin (LT) of ETEC is similar to cholera toxin and acts by increasing intracellular cAMP levels in enterocytes, leading to excessive chloride and fluid secretion into the lumen of the gut, resulting in diarrhea.

Factor II (prothrombin) deficiency leads to a prolonged PT (Prothrombin Time) because it is involved in the extrinsic pathway of the coagulation cascade, which is assessed by the PT test. The aPTT (activated Partial Thromboplastin Time) is normal because the intrinsic pathway is not affected.

When the contact angle is 0?0 raised to the composed with power0?, it indicates perfect wetting, meaning the adhesive spreads completely over the adherend surface. This happens when the adhesive forces (attraction between the adhesive and adherend) are significantly stronger than the cohesive forces (attraction within the adhesive molecules).
