Given increased tooth retention into later years of life, dentists face increasing challenges in maintaining teeth with extensive composite restorations. Accompanying the increase in placement of composite restorations in general practice, there has also been increased evidence that repair, rather than replacement, of composite restorations is being increasingly considered as a treatment option. Previous work has demonstrated that such techniques are often underutilised in practice. The aim of this study was to examine contemporary teaching of composite repair techniques in Scandinavian dental schools. A questionnaire was distributed by email to each of the 12 Scandinavian dental schools in late 2010/early 2011. This questionnaire sought information on the undergraduate teaching of composite repair techniques as well as indications and materials utilised for this technique. A 100% response rate was achieved (12 schools). Eleven of the 12 respondent schools indicated that they included the teaching of composite repair techniques within their dental school programme. The most commonly reported indications for the teaching of the repair of direct composite restorations were tooth substance preservation (11 schools) and reduced risk of harmful effects on the pulp (10 schools). The most commonly taught surface treatment was mechanical roughening of the existing composite restoration, including the removal of the surface layer of material, prior to application of fresh composite (11 schools). Overall, the results of this study showed that the teaching of composite repair techniques is established within Scandinavian dental schools. This may influence the practising habits of dentists graduating from these schools when considering treatment options for defective composite restorations.
随着人们寿命的延长，牙齿的保留时间也越来越长，牙医在维护有广泛复合修复体的牙齿方面面临着越来越多的挑战。随着复合修复体在一般实践中的广泛应用，越来越多的证据表明，修复而不是更换复合修复体越来越被视为一种治疗选择。先前的研究表明，这些技术在实践中往往未得到充分利用。本研究旨在检查斯堪的纳维亚牙科学院中复合修复技术的当代教学情况。2010 年末至 2011 年初，通过电子邮件向 12 所斯堪的纳维亚牙科学院中的每一所分发了一份问卷。该问卷旨在了解本科阶段的复合修复技术教学情况，以及该技术的适应证和所用材料。该问卷得到了 100%（12 所学校）的回复。在 12 所回复的学校中，有 11 所学校表示他们在牙科学院的课程中包括了复合修复技术的教学。报告的直接复合修复修复教学适应证最常见的是保留牙体组织（11 所学校）和降低对牙髓有害影响的风险（10 所学校）。最常教授的表面处理方法是对现有的复合修复体进行机械粗化处理，包括去除材料的表面层，然后再应用新鲜的复合材料（11 所学校）。总体而言，这项研究的结果表明，复合修复技术的教学在斯堪的纳维亚牙科学院中已经确立。这可能会影响从这些学校毕业的牙医在考虑有缺陷的复合修复体的治疗选择时的实践习惯。
