The diagnosis and success of endodontics (root canal treatment) require a comprehensive approach. Subjective symptoms (what the patient feels, such as pain or sensitivity), objective clinical observations (what the dentist sees during examination, such as swelling or decay), and radiographs (X-rays, which show the internal structure of the tooth and surrounding bone) are all essential components used together to accurately diagnose the condition and determine treatment

Wilson disease is a genetic disorder where the body cannot eliminate excess copper, leading to its accumulation in organs like the liver and brain. The key diagnostic criteria typically include: 

Decreased serum ceruloplasmin: Ceruloplasmin is the main copper-carrying protein in the blood. In Wilson disease, levels are usually low because the body cannot properly incorporate copper into the protein.

Increased hepatic copper: Copper accumulates in the liver as the primary site of metabolic dysfunction.

Increased urinary excretion of copper: The body attempts to excrete the excess copper in the urine.

Calcidiol (25 hydroxy cholecalciferol) is a precursor to calcitriol (1,25 dihydroxy vitamin D3), which is the active form of vitamin D. Calcitriol is formed in the kidneys by the action of 1-? hydroxylase and plays a critical role in calcium homeostasis.

The "Postage stamp" method is a technique of bone removal in transalveolar extraction. Multiple small perforations are made in the buccal bone, creating a pattern resembling postage stamp perforations, which allows for easier bone removal and better access to impacted teeth.

 Etching of tooth surface with 37% phosphoric acid creates microporosities in the enamel and dentin. This is the main method of adhesion of composite resin to tooth surface.
 After etching the surface energy of the enamel will increase. This will make it very sticky to any kind of contaminants. If salivary contamination will occur, the salivary proteins will precipitate in the microporosities. This will prevent the adequate penetration of the bonding agent, therby reducing the micotag formation. Hence, complete isolation is essential.
