Crohn/s disease is a type of inflammatory bowel disease (IBD) that can affect any part of the gastrointestinal tract from mouth to anus. A key pathological feature of Crohn/s disease is the presence of non-caseating granulomas (collections of inflammatory cells) in the affected tissue. These granulomas are not typically found in ulcerative colitis, the other major type of IBD.

Reverse labial bow is so called as activation of the bow is done by opening the U-loop, instead of compressing as is seen in the conventional labial bows.

MedicineAn acute inferior wall myocardial infarction (MI) is most commonly caused by an occlusion of the right coronary artery, which supplies the inferior wall of the left ventricle and the right ventricle in most people. When the right ventricle is involved in the infarction, it can lead to right ventricular dysfunction, which severely impairs the heart's ability to pump blood to the lungs and subsequently to the rest of the body. This results in acute and progressive hemodynamic collapse and cardiogenic shock. Cardiogenic shock is the most common cause of death in patients with acute MI.

EndodonticsObturation of root canal should achieve all the mentioned objectives: 1) Tug-back - indicates proper fit and resistance form of the master cone, 2) Hermetic seal - prevents microleakage and bacterial penetration, 3) Fluid-free seal - eliminates pathways for tissue fluids that can support bacterial growth, 4) Additionally should provide: complete filling of canal system, biocompatibility, and dimensional stability. These objectives work together to ensure long-term success by eliminating bacterial contamination and preventing reinfection of the periapical tissues.

While great for temporary cementation, its primary disadvantage for permanent use is its potential to cause tooth discoloration and pulpal irritation.

Radiology
Hyperparathyroidism is a condition characterized by an
overproduction of parathyroid hormone (PTH), which leads to increased bone
resorption and changes in bone density. The radiographic features associated
with hyperparathyroidism include: Loss of Lamina Dura: The lamina dura is the thin layer
of dense bone that lines the tooth socket (alveolus). In
hyperparathyroidism, the loss of lamina dura can be observed due to the
increased osteoclastic activity and bone resorption. Ground Glass Appearance: This refers to a radiographic
appearance of bone that looks hazy or "ground glass" rather than having a
clear, well-defined structure. This appearance is due to the alteration in
bone density and the presence of fibrous tissue replacing normal bone. Osteogenesis Imperfecta: This condition is characterized
by brittle bones due to a defect in collagen formation. Radiographically, it
may show thin cortices and osteopenia, but not typically a ground glass
appearance. Osteopetrosis: This is a condition of excessive bone
density due to impaired osteoclast function. Radiographically, it shows
increased radiopacity (dense bones) rather than a ground glass appearance. Osteitis Deformans (Paget's Disease): This condition is
characterized by disorganized bone remodeling. Radiographically, it can show
a "cotton wool" appearance and enlarged bones, but it does not typically
present with a loss of lamina dura or a ground glass appearance in the early
stages.
