“…A decrease in the number of pre-clinical requirements for dental amalgams was also noted with tooth-colored restorations having replaced some of the previous amalgam quotas in South African dental schools. Similar findings were reported by an Australian study conducted in 2018, where a consensus was reached that dental amalgam should still be taught but the focus must shift to adhesive restorations ( 18 ). There is not much uniformity amongst the universities regarding the exact teaching practices of amalgam posterior restorations, however most of the universities are moving towards a scale-down of amalgam quotas.…”

IntroductionThis paper set out to investigate the relationship between teaching and clinical practice of direct posterior restoration placement at tertiary dental institutions in South Africa.MethodsA cross-sectional study using a mixed methods approach was conducted, and all the South African dental schools were invited to participate. The quantitative phase of the study analyzed the Conservative Dentistry department's records of direct restorations at a single dental school. The number of amalgam and tooth-colored restorations placed by students in the fourth and fifth year of the program from 2004 to 2019 were compared. During the qualitative phase, semi-structured interviews were held with staff from the four dental schools involved with the teaching of direct posterior restorations.ResultsThe predominant direct posterior restoration placed in student clinics over a 15-year period at a South African dental school was tooth colored (75%). Teaching times do not correspond to a decrease in the placement of dental amalgam restorations for both one-surface and two-surface posterior restorations and a concomitant increase in the tooth-colored restorations.DiscussionAcademic staff involved in teaching identified that South Africa's ratification of the Minamata Convention has consequences for dental education and training. However, all schools reported that dental amalgam would continue to be taught in the absence of an appropriate alternative.

“…We can now look at replacement rather than repair. 7 The earlier composite material, the micro fills, lacked condensable properties and strength and were not used in load-bearing areas such as posterior teeth. Now bulkfill composite material has been introduced.…”

Dental amalgam has been used as a restorative material in dentistry for the past 150 years. This material has been used to restore posterior teeth throughout the world and is also used in South Africa. Dental amalgam has been the material of choice for patients presenting with large tooth decay areas, including the loss of cuspal areas. The reason for this is that dental amalgam was always considered strong and durable. Compared to alternate dental materials, this material could also withstand the significant forces associated with chewing and biting. Dental amalgam is also considered more cost-effective than alternate dental materials such as conventional glass ionomers, resin-modified glass ionomers, resin composite and ceramic restorations, making it more feasible and material of choice in lower economic countries, including South Africa.
