Answer :

Final answer:

Enamel decay and removal for bonding procedures.

It is necessary to remove a thin layer of enamel using rotary instruments before etching and bonding, especially in procedures like resin-bonded veneers. This process helps create a suitable surface for bonding materials and improves the longevity of the restoration.
