Oral SurgeryTorus palatinus reduction involves removing a bony prominence from the palate. Acrylic splints provide stabilization, protect the surgical site, and prevent hematoma formation. Other conditions like mandibular alveoplasty do not require splints for similar reasons.

Oral SurgeryMost commonly used local anaesthesia is 1: 80,000 xylocaine HCL.

Oral SurgeryThe role of sodium metabisulfite in local anaesthetic agent is as a preservative.

Oral SurgeryThe advantage of chisel and mallet over bur in removing bone is that no coolant is necessary.

Oral SurgeryExplanation:
Adrenaline (epinephrine) is commonly added to local anesthetics to prolong their effect and reduce bleeding in the area. It works by constricting blood vessels, which decreases the rate of absorption of the anesthetic into the bloodstream, thereby enhancing its duration of action.

Oral SurgeryHilton's method is a surgical technique primarily used for the drainage of abscesses. This method involves creating an incision to allow the pus to escape, thereby relieving pressure and promoting healing.

Oral SurgerySevere acidosis, particularly metabolic acidosis, can occur following
prolonged cardiac arrest and subsequent CPR. The primary goal in managing such
cases is to restore normal pH levels in the body, which is crucial for proper
cellular function and overall physiological homeostasis.
1. Sodium bicarbonate Sodium bicarbonate is a strong base that reacts with
hydrogen ions (H+), which are responsible for acidity in the blood, to form
carbon dioxide (CO2) and water (H2O). This reaction helps to neutralize the
excess hydrogen ions, thereby raising the pH of the blood. It is administered
intravenously because it allows for rapid distribution throughout the body and
direct access to the circulatory system where it can counteract acidosis most
effectively. The intravenous route ensures that the medication reaches the
bloodstream quickly and in a controlled manner, making it the preferred method
for acute and severe cases.
2. Adrenaline (epinephrine)*: Although adrenaline is a crucial medication used
in CPR for its vasopressor and cardiac stimulant effects, it is not the primary
treatment for severe acidosis. Adrenaline is typically administered to improve
cardiac output and blood pressure during CPR.
