Abstract

OBJECTIVES

To identify potential changes in various aspects of teaching and to ascertain whether previously found inconsistencies in the teaching of criteria, indications and operative techniques for the repair of defective composite restorations at German dental schools have been resolved.

METHODS

A validated questionnaire was used to gain the information sought. It was sent to all dental schools in Germany (n = 30). Whenever possible, data were compared to previous studies conducted in 2000 and 2009. Statistical analysis was performed using Fisher's exact tests (p < 0.05).

RESULTS

Twenty-nine schools responded to the survey - a response rate of 97%. All respondents indicated positive experiences with the repair of restorations. The teaching of repairs in 2018 (90%) was found to be comparable to the findings from the 2009 survey (88%, p = 1.000), but significantly increased since the 2000 survey (50%, p = 0.006). Main reasons reported for teaching repairs are tooth substance preservation (97%) and reduction of pulpal damage (79%). Main clinical indications are marginal defects and secondary caries. When performing repairs, almost all dental schools were found to teach both mechanical and adhesive substrate surface conditioning. Marked variation was observed in the method of mechanical surface treatment, with air abrasion having gained widespread popularity. The average expected longevity of repairs was 7.4 ± 3.0 years.

CONCLUSIONS

The teaching of the repair of resin composite restorations is widespread in dental schools in Germany. Aspects of this teaching were found to be more consistent between dental schools than in previous surveys, albeit variation in operative techniques still exists.

CLINICAL SIGNIFICANCE

Graduates from dental schools in Germany may be found to be well equipped with the knowledge and skills to perform repairs of defective resin based composite restorations in clinical practice.

摘要

目的

确定教学各个方面的潜在变化，并确定德国牙科学校在复合树脂修复体的修复标准、适应证和手术技术教学方面以前发现的不一致是否已经得到解决。

方法

使用经过验证的问卷来获取所需信息。它被发送到德国所有的牙科学校（n=30）。只要有可能，数据就与 2000 年和 2009 年进行的先前研究进行了比较。使用 Fisher 精确检验进行统计分析（p<0.05）。

结果

29 所学校对调查做出了回应——回应率为 97%。所有受访者都表示在修复修复体方面有积极的经验。2018 年的修复教学（90%）被认为与 2009 年调查的结果（88%，p=1.000）相当，但与 2000 年调查（50%，p=0.006）相比有显著增加。报告的主要教学原因是保留牙体组织（97%）和减少牙髓损伤（79%）。主要的临床适应证是边缘缺损和继发龋。在进行修复时，几乎所有的牙科学校都被发现教授机械和粘合基底表面处理。在机械表面处理方法上观察到明显的差异，其中空气喷砂已广泛普及。修复的平均预期寿命为 7.4±3.0 年。
