Oral SurgeryThe treatment of choice for TMJ ankylosis is condylectomy. This is a surgical procedure where the ankylotic tissue is removed from the temporomandibular joint, allowing for the restoration of normal joint movement.
Exercise and warm packs may be used as adjunctive treatments to help manage the symptoms of TMJ ankylosis and maintain joint mobility, but they are not the primary treatment for the condition itself. Steroid therapy and sclerosing solutions might be used in some cases, but condylectomy is the definitive surgical procedure to address the ankylosis directly by removing the bony or fibrous tissue that is obstructing the joint..

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.

Oral SurgeryLidocaine is used more commonly in dentistry because it causes lesser incidence of allergic reactions.

Oral SurgeryThe middle superior alveolar nerve (MSA) is one of the branches of the maxillary
nerve that innervates the buccal gingival of the maxillary teeth, including the
second premolar. The anterior palatine nerve innervates the palatal aspect,
while the buccal nerve innervates the buccal mucosa and the anterior part of the
palate.
