Physiology
Endorphins, particularly ?-endorphin, are opioid peptides that act as natural painkillers. They are released during stress and pain and bind to opioid receptors in the brain and spinal cord to inhibit the transmission of pain signals. While they do have secondary effects on mood and stress response, their primary function is pain inhibition.

Orthodontics
SOLUTION Mechanical approaches for aligning unerupted teeth. Orthodontic traction to pull an unerupted tooth toward the line of the arch should begin as soon as possible after surgery
Ideally a fixed orthodontic appliance should already be in place before the unerupted tooth is exposed, so that orthodontic force can be applied immediately.
If this is not practical, active orthodontic movement should being no later than 2 or 3 weeks post-surgically.

MAC is a measure of potency; lower MAC indicates higher potency. A MAC value over 100% (like 105% for N2O) indicates that it is a very weak anesthetic, requiring a theoretical concentration higher than atmospheric limits to achieve anesthesia in 50% of patients.

EndodonticsThis statement is untrue because calcium ions in the calcific bridge come from the bloodstream via pulp tissue, not directly from the calcium hydroxide paste. The hydroxyl ions create the alkaline environment that promotes hard tissue formation.
