Step-by-step explanation:
A Class II restoration in dentistry refers to the restoration of a tooth that involves the proximal surfaces (sides) of a posterior tooth. It is commonly known as a dental filling. This type of restoration is used when there is decay or damage to the tooth that extends into the space between the back teeth.
For example, if there is a cavity on the side of a molar tooth, a Class II restoration would involve removing the decayed portion and filling it with a dental material like composite resin or amalgam.
The goal of a Class II restoration is to restore the tooth's structure, function, and aesthetics while preserving as much of the natural tooth as possible.
