To systematically assess aspects of teaching of posterior composite restorations (PCRs) in permanent teeth in dental schools.
Quantitative studies reporting on dental schools' teaching regarding the placement of PCRs in permanent teeth. Random-effects meta-analyses and meta-regressions were performed. Risk of bias was assessed based on the Medical Education Research Study Quality Instrument (MERSQI).
Electronic databases (MEDLINE via PubMed, EMBASE via Ovid, Web of Science, and Scopus) were searched in January 2023.
Forty sources reporting on 34 studies having surveyed 1,286 dental schools were included. Overall, 92.7% (95%-CI: 88.2-95.5) of dental schools reported to teach PCRs. PCRs in three-surface Class II cavities are taught by 82.0% (95%-CI: 70.4-89.7). The mandatory use of liners in deep cavities is taught by 78.3% (95%-CI: 68.9-85.5), and 44.0% (95%-CI: 34.3-54.2) reported to teach bulk-fill composites. While most posterior restorations placed by students were composites (56.1%; 95%-CI: 46.0-65.8), 94.7% (95%-CI: 86.6-98.0) of dental schools (still) teach posterior amalgam restorations. The proportion of dental schools teaching PCRs in three-surface Class II cavities increased and the mean proportion of PCRs among all posterior restorations increased over time (p≤0.003).
The teaching of PCRs in dental schools around the world reflects the increased use of resin composite in clinical practice, with students in countries where dental amalgam continues to be used, placing more posterior composites than restorations of dental amalgam. The teaching of PCRs, which is anticipated to increase, will continue to be refined with further developments in adhesive materials, devices, instrumentation, and techniques.
Graduating dentists can be expected to be familiar with the use of resin composites for the restoration of posterior teeth.
系统评估牙科学校对后牙复合树脂修复（PCR）教学的各个方面。
定量研究报告了牙科学校对后牙永久牙齿 PCR 放置的教学情况。进行了随机效应荟萃分析和荟萃回归。基于医学教育研究质量工具（MERSQI）评估偏倚风险。
2023 年 1 月，在电子数据库（PubMed 中的 MEDLINE、Ovid 中的 EMBASE、Web of Science 和 Scopus）中进行了搜索。
纳入了 40 篇报告了 34 项研究的资料，这些研究调查了 1286 所牙科学院。总体而言，92.7%（95%可信区间：88.2-95.5）的牙科学院报告教授 PCR。在三壁 II 类窝洞中教授 PCR 占 82.0%（95%可信区间：70.4-89.7）。在深窝洞中强制使用衬里的占 78.3%（95%可信区间：68.9-85.5），44.0%（95%可信区间：34.3-54.2）报告教授大体积充填复合材料。尽管学生放置的大多数后牙修复体是复合材料（56.1%；95%可信区间：46.0-65.8），但 94.7%（95%可信区间：86.6-98.0）的牙科学院（仍然）教授后牙银汞合金修复体。教授三壁 II 类窝洞中 PCR 的牙科学院比例增加，随着时间的推移，学生放置的 PCR 在后牙所有修复体中的比例也增加（p≤0.003）。
世界各地牙科学校对 PCR 的教学反映了临床实践中树脂复合材料使用的增加，在继续使用牙科银汞合金的国家中，学生放置的后牙复合材料比银汞合金修复体更多。预计随着黏附材料、器械、仪器和技术的进一步发展，PCR 的教学将继续得到改进。
预计毕业牙医熟悉使用树脂复合材料修复后牙。
