Oral Surgery
Proper abscess drainage involves creating an incision to allow pus to drain completely. Probing with an artery forceps ensures complete evacuation of the cavity. Other methods, like simple aspiration or superficial incisions, may not adequately drain the abscess.

PeriodonticsAfter 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.

Anatomy
The external (lateral) pterygoid muscle has two primary functions: it assists in depressing the mandible (opening the mouth) and in moving the mandible forward (protrusion). This dual function distinguishes it from other muscles of mastication, which primarily elevate the mandible.

PhysiologyAnswer: 1) Induction of glucokinaseExplanation: Insulin enhances glucose uptake in the liver by inducing the synthesis of glucokinase, an enzyme that converts glucose into glucose-6-phosphate. This "glucose trapping" mechanism keeps intracellular glucose levels low and promotes further glucose entry into the cell.
