EndodonticsSuccess of calcium hydroxide pulpotomy is primarily determined by continued root formation and apexogenesis in immature permanent teeth. While calcific bridge formation occurs, the main goal is preserving pulp vitality for root development.

PhysiologyAngiotensin I is formed by the action of renin on Angiotensinogen, which is produced by the liver and released into the bloodstream.

NEETMDSAbfraction is the loss of tooth structure at the cervical area (where the tooth meets the gum line) caused by biomechanical loading forces (flexure) on the tooth, resulting in characteristic V-shaped or wedge-shaped lesions with vertical fracture lines.

ProsthodonticsNon-rigid or semi-rigid connectors are used in dental bridges when there is a need to accommodate non-parallel abutments (option 2). This design allows for some movement between the components of the bridge, which can help in achieving a better fit and function when the abutments are not parallel.

General MicrobiologyAdoptive immunization involves the transfer of readymade immune cells, such as antibodies, from a donor to a recipient. Tetanus immunization is typically achieved through active immunization with the tetanus toxoid, which induces the body to produce its own antibodies against the tetanus toxin. Passive immunization, on the other hand, is achieved by injecting tetanus antitoxin, which provides immediate but temporary protection by neutralizing the toxin in the recipients body. The statement is incorrect because tetanus toxoid is used for active immunization, not adoptive immunization.

Transferrin is a glycoprotein synthesized by the liver that acts as the primary iron-transport protein in the blood. It binds to iron and transfers it to cells that require it, such as erythrocytes for hemoglobin synthesis.

EndodonticsFor a child with mid-crown fracture in permanent maxillary central incisor with necrotic pulp and incompletely formed root with open apex, the treatment of choice is apexification. This procedure is indicated because: 1) Open apex prevents conventional root canal obturation, 2) Necrotic pulp requires complete debridement, 3) Apexification induces calcified barrier formation at root apex, 4) Allows subsequent root canal obturation, 5) Preserves the tooth for normal function. Calcium hydroxide or MTA are commonly used materials for apexification. Pulpotomies are not indicated for necrotic pulps.
