Class V restorations are classified as what type of filling?

1. Smooth surface filling

2. Complex filling

3. Root filling

4. Restorative filling

The correct answer is: Smooth surface filling

Class V restorations are classified as smooth surface fillings. This type of filling is specifically designed to address carious lesions or non-carious lesions on the smooth surfaces of teeth, particularly in areas where the gums have receded. Class V restorations typically occur on the facial or lingual surfaces of the teeth, usually around the gum line, making them distinct from other types of restorations that may involve more complex shapes or features associated with posterior teeth. Smooth surface fillings emphasize the restoration of areas that do not have the additional topography associated with pits and fissures, which are typically addressed in other classifications such as Class I or Class II restorations. The goal of a Class V restoration is to provide a smooth, even surface that blends aesthetically with the tooth and restores function while preventing further decay.
