Class V restorations are used to repair smooth surface cavities located on the gingival third of the facial/lingual surfaces of teeth. These lesions are caused by caries, abrasion, or erosion and involve only one surface of the tooth. Materials used for Class V restorations include amalgam, composite, resin-modified glass ionomer cement, and compomer. The clinical preparation involves isolation, outlining a trapezoidal form in the gingival third, adding retention grooves or coves, placing the restorative material, and finalizing the preparation.
