This paper set out to investigate the relationship between teaching and clinical practice of direct posterior restoration placement at tertiary dental institutions in South Africa.
A 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.
The 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.
Academic 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.
本文旨在研究南非高等牙科机构中直接后牙修复体放置的教学与临床实践之间的关系。
采用混合方法进行横断面研究，并邀请了南非所有的牙科学校参与。该研究的定量阶段分析了一所牙科学校保守牙科部门的直接修复记录。比较了2004年至2019年该项目第四年和第五年学生放置的汞合金修复体和牙齿颜色修复体的数量。在定性阶段，对参与直接后牙修复教学的四所牙科学校的工作人员进行了半结构化访谈。
在一所南非牙科学校的学生诊所中，15年间放置的主要直接后牙修复体是牙齿颜色的（75%）。对于单面和双面后牙修复体，教学时间与汞合金修复体放置量的减少以及牙齿颜色修复体放置量的相应增加并不对应。
参与教学的学术人员指出，南非批准《水俣公约》对牙科教育和培训产生了影响。然而，所有学校都报告称，在没有合适替代方案的情况下，汞合金仍将继续被教授。
