Beveling the cavosurface for Class V amalgam restorations is:

True False Only for anterior teeth Only for posterior teeth

Correct Answer:

False

Explanation:

Beveling the cavosurface margin is a technique tied to improving bonding and esthetics with adhesive materials, where increasing the surface area helps create a smoother, more seamless transition. Amalgam relies on mechanical retention and proper contouring rather than adhesive bonding, so a bevel at the cavosurface doesn’t provide a meaningful benefit. In fact, beveling at the cervical margin can thin or remove enamel and dentin in a region where the tooth is already vulnerable, potentially weakening the margin and not improving the seal of the restoration. For Class V amalgam restorations, beveling is not indicated, making the statement false.
