To investigate current teaching and operative techniques for posterior composite resin restorations in dental schools in Austria, Germany, and Switzerland.
Data on teaching, including operative techniques applied in the placement of posterior composites, were collected by means of a 25-item validated questionnaire sent to the Heads of Department of Operative/Restorative Dentistry at all 38 dental schools in Austria, Germany, and Switzerland. Responses were compiled in Excel and analysed.
Thirty-three schools responded to the survey, resulting in a response rate of 87 %. All dental schools indicated teaching of 2- and 3-surface posterior composite restorations. About one third only of the preclinical teaching is assigned to teaching posterior composite restorations, while the vast majority of posterior restorations placed by students in their clinical instruction are composite (89.6 ± 9.3 %). Most dental schools teach few contraindications to posterior composites, except for adverse reactions such as allergies. All dental schools consider moisture control to be important, while approaches to the management of exposed dentine differ.
The teaching of the placement of posterior composite restorations is common to all the dental schools in Austria, Germany, and Switzerland which participated in the present study. Most aspects of the teaching were found to be consistent amongst the schools. However, marked variations were observed in respect of operative techniques for the placement of posterior composites.
Graduates from dental schools in Austria, Germany, and Switzerland may be found to have received theoretical, preclinical, and clinical instruction in posterior composites, but do show some variation in approach to the management of exposed dentine.
调查奥地利、德国和瑞士牙科学院中后牙复合树脂修复的教学和操作技术现状。
通过向奥地利、德国和瑞士 38 所牙科学院的口腔修复/牙髓科主任发放 25 项内容已验证的调查问卷收集教学数据，包括应用于后牙复合树脂修复体放置的操作技术数据。将回复结果汇编到 Excel 中并进行分析。
共有 33 所学校对该调查做出了回应，应答率为 87%。所有的牙科学院都表示在教授 2 面和 3 面后牙复合树脂修复体。只有约三分之一的临床前教学分配给了后牙复合树脂修复体的教学，而学生在临床实习中放置的绝大多数后牙修复体是复合树脂（89.6±9.3%）。除过敏等不良反应外，大多数牙科学院仅教授少数后牙复合材料的禁忌症。所有的牙科学院都认为控制水分很重要，而暴露牙本质的处理方法则有所不同。
参与本研究的奥地利、德国和瑞士的所有牙科学院都普遍教授后牙复合树脂修复体的放置。研究发现，各学校的教学大多具有一致性。然而，在放置后牙复合材料的操作技术方面，观察到明显的差异。
来自奥地利、德国和瑞士牙科学院的毕业生可能在理论、临床前和临床后牙复合材料方面都接受了指导，但在暴露牙本质的处理方法上确实存在差异。
