Item The effect of enamel etchants and a cleaning agent on cut dentine: an in vitro study(1985) Sparrius, O.; Grossman, E. S.Cavities 1,25 x 2,00mm were prepared in the cervical dentine of extracted human premolar teeth using a no. 577 tungsten carbide bur. The cavity depth was standardised at 1mm with the aid of a depth gauge fitted to the high speed airturbine. The cavities were hemisected with a low speed, water cooled, diamond disc saw, then cleaned with water and air. Thereafter the following solutions were applied to six cavities each as per manufacturers' instructions: Anhydron; Chemfill (Citric Acid); Enamelbond etchant and Scotchbond etchant gel. Once the cavities had been cleaned and dried, the specimens were prepared for scanning electron microscopy (SEM) and viewed at magnifications of x35, x200 and x2000. Cavity walls and floors were viewed separately and representative areas photographed. Similarly prepared unetched cavities served as a control.Item Relationship between fluoride concentration in enamel, DMFT Index, and degree of fluorosis in a community residing in an area with a high level of fluoride(1976) Bischoff, J. I.; Van Der Merwe, E. H. M.; Retief, D. H.; et al.The DMFT index, degree of fluorosis (DEGF), fluoride concentration in enamel (F), and depth of etch (D) were determined in participants living in an area with a high fluoride level. A statistically significant difference was found between men and women for F and D. A significant correlation was established between F and DEGF and between F and age for men, but not for women.Item Activation analysis in biological material(1975) Turkstra, J.; Retief, D.
