Oral Surgery
A tracheostomy is a surgical procedure that involves creating an opening in
the trachea (windpipe) to facilitate breathing. The preferred site for making
the incision during a tracheostomy is the cricothyroid ligament,
which is located between the cricoid and thyroid cartilages. Cricothyroid ligament: This ligament is relatively
superficial and provides a safe access point to the airway, especially in
emergency situations. It is often chosen for emergency tracheostomy because
it is easier to locate and access quickly.

Platinized gold foil is a combination of gold and platinum where 15% of the content is platinum. It is produced by rolling layers of gold and platinum together to achieve the desired thickness and distribution of the platinum within the gold foil. This process creates a homogeneous mixture that enhances the hardness and wear resistance of the restoration, making it suitable for high-stress areas like incisal edges and cusp tips.

Bioactive glass is a synthetic material typically composed of silicon dioxide , sodium oxide , calcium oxide , and phosphorus pentoxide. These components are in the form of salts of sodium and calcium, silicon dioxide, and phosphates. Hydroxyapatite is a natural mineral found in bones and teeth, and it is the material that the body forms on the surface of the bioactive glass when it is implanted, rather than a component of the original synthetic glass itself.

Oral PathologyDiastema (spacing between teeth) is never directly associated with TMJ pathosis. TMJ disorders commonly cause open bite due to condylar resorption or growth disturbances, closed bite due to posterior teeth super-eruption, and traumatic occlusion due to altered mandibular positioning. Diastema is typically related to tooth size-arch length discrepancies, developmental factors, or periodontal disease, not TMJ dysfunction.
