Dental Materials
The condensation silicone impression materials are supplied as a base paste and a low-viscosity liquid catalyst (or a paste catalyst).
Putty is a high-viscosity material that has been developed in order to overcome the large polymerization shrinkage of the condensation silicone impression materials.
All the other impression materials are generally supplied as catalyst paste & base paste.

Oral PathologyHemophilia A is primarily due to deficiency of Factor VIII, and Hemophilia B is due to Factor IX deficiency. These are inherited X-linked genetic disorders caused by mutations in the F8 or F9 genes respectively. Classical hemophilia is not due to autoimmune mechanisms, though acquired hemophilia (rare) can involve autoantibodies against Factor VIII. Prothrombin deficiency and Vitamin K deficiency cause different coagulation disorders.

RadiologyAcetic acid is a key ingredient in the fixing solution used in radiography. It acts as a stop bath, neutralizing the developer and maintaining the acidic environment necessary for proper fixation. Hydroquinone and elon are developer agents, while sodium bisulfate is not typically part of the fixing process.

ProsthodonticsWhen replacing all missing maxillary incisors with PFM restorations, both canines and first premolars should be used as abutments. The four missing incisors create a large span requiring additional support beyond just the canines. Including the first premolars provides better force distribution, stability, and reduces stress on individual abutments, improving long-term prognosis.

General Medicine
Both the aPTT (activated Partial Thromboplastin Time) and PT (Prothrombin Time) are prolonged in the case of factor VIII deficiency, which is characteristic of Hemophilia A. This is because factor VIII is involved in both the intrinsic and common pathways of the coagulation cascade.

Public Health DentistryThe correct concentration for topically applied acidulated phosphate fluoride is 1.23% (Answer: 2). This concentration is commonly used in various dental products like gels, foams, and varnishes for professional in-office applications to strengthen tooth enamel and prevent decay. It is acidulated to facilitate better penetration into the enamel.
