The traditional GV Black cavity classification is now more than 80 years old. It was designed primarily for nonadhesive materials at a time when concepts of remineralization and caries prevention were limited. With a plethora of restorative materials and a better understanding of the caries process, the clinician can now restrict loss of tooth substance with minimal intervention. A parallel system of classification based on site and size at the carious lesion is advocated here.
