ABSTRACT

Evolution of cavity preparation has come a long way since its introduction by G.V. Black in early 1900’s. It stressed more on cutting of a healthy tooth structure along with carious tissue in order to provide adequate retention. Nowadays with the increased quality of the restorative materials retention is no longer an issue related to cavity formation. G.J. Mount and W.R. Hume in 1997 proposed a newer classification of carious lesion and cavity preparation which dealt with cutting of only the demineralised carious region. Several techniques like: chemomechanical caries removal, air abrasion, lasers and ozone evolved along with the minimal cavity preparation which was summarised to be known as minimal intervention dentistry or minimal invasive dentistry.
