Item Failure at the dental restorative-etched enamel interface(1973) Retief, D. H.Item Failure at the dental restorative etched enamel interface(1973) Retief, D. H.None of the restorative materials available to the dental profession adhere to tooth structure. The bonding of these materials could be greatly increased by etching the enamel surface prior to the placement of the restorative material. Conditioning of the enamel surface with phosphoric acid or an attenuated phosphoric acid solution is now an accepted procedure and widely applied in restorative and preventive dentistry.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. H.; Cleaton-Jones, P. E.Item The quantitative determination of Ca, Na, Al, Mg, and Cl in normal enamel and dentine by neutron activation and high resolution gamma spectrometry(1970) Retief, D. H.; Cleaton-Jones, P. E.; Turkstra, J.Item The fluoride concentration in the enamel of permanent central incisors(1971) Barbakow, F. H.; De Kock, A. C.; Retief, D.
