NEETMDSThe C-factor (configuration factor) in dentistry is the ratio of bonded to unbonded (free) surfaces in a tooth cavity preparation. A higher C-factor can lead to increased stress on the adhesive bond, potentially causing issues like microleakage. Class V cavities (located on the smooth facial or lingual surfaces near the gum line) typically have the highest C-factor because they have a large number of bonded surfaces relative to their free surface area.

The final polish of a cast gold alloy to achieve a smooth polished surface is
done by
1) Pickling: This is a process used to remove oxides and impurities from the
surface of a metal before applying a final finish. However, it does not provide
the final polish.
2) Electropolishing: This technique uses an electrical current to dissolve the
metal surface and create a smooth finish, but it is not commonly used for gold
alloy restorations.
3) Sandblasting: This method involves propelling an abrasive material against
the metal surface to smooth and clean it, but it is too aggressive for the final
polish of a gold alloy restoration.
4) Rouge: Rouge is a fine abrasive paste used with a polishing wheel or point to
achieve the final polish on a cast gold alloy restoration. It removes minor
imperfections and gives a high luster to the metal.
The correct answer is 4) Rouge, as it is the standard technique for achieving a
smooth, polished surface on cast gold alloys.
