目的：探讨大洋洲（澳大利亚、新西兰、斐济、巴布亚新几内亚）牙科学校后牙复合修复体的教学和手术技术现状。方法：将一份24题的问卷邮寄给16所牙科学校的牙外科/修复科主任。在Excel中编制问卷并进行分析。结果：本研究有效率为94% （n = 15）。所有被调查学校都教授使用后牙复合材料治疗前磨牙和磨牙的咬合和咬合近端腔。临床前教学中用于复合材料的平均百分比大于汞合金（39% vs 29%）。预计5年后，后置复合材料/汞合金的比例将达到3:1。学生放置的大多数后牙修复体是复合材料（平均64%，范围从10%到100%），汞合金占所放置修复体的19.5%（范围从0%到50%）。槽型空腔是最常教授的制备技术（80%），大多数学校（67%）教授强制使用橡胶坝来控制水分。复合材料安置最常见的禁忌症（67%的学校）是复合材料不良反应史。预计大洋洲将在8-10年内逐步停止使用汞合金。结论：尽管微创入路在世界范围内越来越普遍，但在大洋洲仍在教授汞合金的使用。未来的研究应评估后牙复合材料的临床教学是否与主流牙科实践的材料发展和趋势保持一致。
Objective: To investigate current teaching and operative techniques of posterior composite restorations in dental schools in Oceania (Australia, New Zealand, Fiji and Papua New Guinea).Methods: A 24-item validated questionnaire including closed and open questions was mailed to the Heads of Department of Operative/Restorative Dentistry in 16 dental schools. Responses were compiled in Excel and analyzed.Results: The response rate of this study was of 94% (n = 15). All respondent schools taught the use of posterior composites for occlusal and occluso-proximal cavities in premolars and molars. The mean percentage of preclinical teaching devoted to composites was greater than for amalgam (39% vs 29%). This proportion was anticipated to be 3:1 for posterior composite/amalgam in five years' time. Most posterior restorations placed by students are composites (average 64%, ranging from 10 to 100%), with amalgam representing 19.5% of the restorations placed (ranging from 0%-50%). Slot-type cavities were the preparation techniques most commonly taught (80%) and most schools (67%) teach the mandatory use of rubber dam for moisture control. The most common contraindication to composite placement (67% of the schools) was a history of adverse reaction to composites. The phase down of teaching and use of amalgam in Oceania is expected to occur within 8-10 years.Conclusions: Despite minimally invasive approaches becoming increasingly common worldwide, the use of amalgam is still taught in Oceania. Future studies should assess whether the clinical teaching of posterior composites is in keeping with material development and trends in mainstream dental practice.
