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.

Orthodontics
SOLUTION Optimum orthodontic force is one, which moves teeth most rapidly in the desired direction, with the least possible damage to tissue and with minimum patient discomfort. Oppenheim and Schwarz following extensive studies stated that the optimum force is equivalent to the capillary pulse pressure, which is 20-26 gm/sq. cm of root surface area. From a clinical point of view, optimum orthodontic force has the following characteristics: From a histologic point of view the use of optimum orthodontic force has the following characteristics: 1) The vitality of the tooth and supporting periodontal ligament is maintained
1) Products rapid tooth movement
2) Minimal patient discomfort
3) The lag phase of tooth movement is minimal
4) No marked mobility of the teeth being moved
2) Initiates maximum cellular response
3) Produces direct or frontal resorption

RadiologyPA (Posteroanterior) view is best for visualizing medially displaced condylar neck fractures. This view provides clear visualization of the condylar region and can show medial displacement of fracture fragments. The AP projection gives better detail of condylar neck positioning.

PathologyCells die by one of two mechanisms – necrosis or apoptosis • Two physiologically different processes – Necrosis – death by injury – Apoptosis – death by suicide Appoptosis: Disintegration of cells into membrane-bound particles that are then eliminated by phagocytosis or by shedding.

Periodontics
The transseptal fibers are a type of periodontal ligament fiber that run between the cementum of adjacent teeth. They help maintain the interproximal relationship between teeth and provide support to the gingival tissue. These fibers are important for the stability of the dental arch and help resist the forces that may cause teeth to drift apart.
