The “extension for prevention” dogma by G.V Black had been jettisoned while the modern concept of conservatism or minimal cavity preparation has been well embraced by dental practitioners. However, there are some limitations in clinical teaching of conservative amalgam cavity preparation which include late patient presentation with large carious lesions, lack of appropriate conservative instruments and restorative materials. This article discusses limitations in teaching, learning and practice of conservative amalgam cavity preparation in the developing countries.
