Physiology
The stomach protects itself from the harsh acidic environment and its own digestive enzymes through the secretion of a thick layer of mucus by mucosal cells. This mucus barrier forms a physical and chemical barrier that shields the underlying tissue from the acid and pepsin. Additionally, the stomach lining has a high turnover rate and is continuously regenerated, and the enzymes in the gastric juice are inactive until they come into contact with food.

While lung cancer itself is not a direct risk factor for venous thrombosis, it can be associated with hypercoagulable states due to the presence of tumor cells or paraneoplastic syndromes. The other options (orthopedic surgery, estrogen use for contraception, and a family history of DVT) are all recognized conditions that increase the risk of developing venous thrombosis.

EndodonticsWhen moderate extrusion of obturating material and sealer beyond the apex occurs, it is undesirable for several reasons. While it does not necessarily mean the prognosis is poor, there is a higher likelihood of postoperative discomfort due to the potential for chemical irritation of the periapical tissues. Additionally, if the sealer is not resorbed, it may cause a foreign body reaction, and gutta-percha extrusion can sometimes lead to severe periradicular reactions. The best approach in such a case is to obturate the remaining canal up to the point of obstruction and observe the patient's symptoms and healing response.
