IN-VITRO TECHNIQUES FOR EROSIVE LESION FORMATION AND EXAMINATION IN DENTAL ENAMEL

An in vitro experimental model has been developed for erosive lesion f ormation in dental enamel which can mimic in vivo conditions at the to oth surface. The features of this model provide a very reproducible me thod of producing erosive lesions in several teeth under identical con ditions which can be varied to allow examination of a number of differ ent parameters. A replica impression technique has also been developed for subsequent non-destructive microscopic examination of the lesions and comparison with in vivo lesions.
