A 10-question survey was mailed to the 10 Canadian faculties of dentistry to determine current approaches to teaching undergraduates about silver amalgam and resin composite for posterior restorations in adults and children. Responses were received from all 10 pedodontic programs and from 8 of the 10 operative and restorative programs. The use of silver amalgam and posterior composite for restorations of primary and permanent teeth is covered in the curricula of all dental schools, but the relative emphasis on the 2 materials varies. In the operative and restorative programs, curriculum time devoted to silver amalgam is either greater than or equal to that devoted to posterior composite. Five of the 8 schools reported greater educational emphasis on silver amalgam for the permanent dentition; however, course directors noted that the preference among patients seen in clinics is tending toward composite restorations. Curricula appear designed to educate students about the optimal use of both materials. Requirements for performance of restorations during training generally do not specify the type of material; these requirements range from 60 restorations to 250 surfaces. Five of the 8 schools conduct clinical competency tests with both materials. The responses from the pedodontic programs were more diverse. The proportion of curriculum time devoted to each type of material in these programs ranged from less than 25% to more than 75%. Five schools reported more emphasis on silver amalgam, 3 schools reported equal emphasis, and 2 schools reported more emphasis on posterior composite. No clinical requirements were specified in any of the undergraduate pedodontic programs. Within some of the faculties, there were differences between the operative and restorative program and the pedodontic program with respect to emphasis on different materials for the posterior dentition.
一份包含10个问题的调查问卷被邮寄给了加拿大的10所牙科学院，以确定当前在教授本科生关于成人及儿童后牙修复中银汞合金和树脂复合材料方面的方法。收到了所有10个儿童牙科学项目以及10个口腔手术与修复项目中8个项目的回复。所有牙科学院的课程中都涵盖了银汞合金和后牙复合材料用于乳牙和恒牙修复的内容，但对这两种材料的相对重视程度有所不同。在口腔手术与修复项目中，分配给银汞合金的课程时间要么大于要么等于分配给后牙复合材料的时间。8所学校中有5所报告称在恒牙列方面对银汞合金的教育更重视；然而，课程主任指出，诊所中患者的偏好正倾向于复合树脂修复。课程似乎旨在教育学生如何最佳地使用这两种材料。培训期间修复操作的要求通常未指定材料类型；这些要求从60次修复到250个表面不等。8所学校中有5所使用这两种材料进行临床能力测试。儿童牙科学项目的回复更为多样。这些项目中分配给每种材料类型的课程时间比例从不到25%到超过75%不等。5所学校报告更重视银汞合金，3所学校报告同等重视，2所学校报告更重视后牙复合材料。任何本科儿童牙科学项目中都未规定临床要求。在一些学院内部，口腔手术与修复项目和儿童牙科学项目在对后牙不同材料的重视程度方面存在差异。
