Increased concerns about the safety of amalgam restorations in children have resulted in many dental schools emphasizing the teaching of alternative dental materials. This study investigated the current teaching of different dental materials for use in posterior teeth in the United States predoctoral pediatric dentistry programs. In 2011, the authors invited the chairs of the predoctoral pediatric dentistry departments in all accredited dental schools at that time ( = 57) to participate in an internet-based survey. Descriptive statistics were calculated to describe the frequency of using different restorative materials. Regression models were developed to explore the factors related to the use of dental restorations in predoctoral pediatric clinics. Among the 44 dental schools that responded (77% response rate), 74% used amalgam, and 93% used composite in primary posterior teeth. Glass ionomer was used by 61% of the schools in primary posterior teeth. Placing amalgam in primary posterior teeth was associated with programs that treated more 3-5-year-old patients (β = .302, < .043), whereas the use of glass ionomer was associated with having students serving at off-site satellite dental clinics (β = .015, < .012). In general, having departments with chairs who had positive attitudes towards Minimal Invasive Dentistry (MID) used composite (β = .091, < .0001) and glass ionomer (β = 103, < .0001) more frequently and were less likely to use amalgam (β = -.077, < .005) in primary posterior teeth. Although teaching MID concepts in predoctoral pediatric clinics in dental schools is increasing, the use of amalgam in posterior primary and permanent teeth is still widely practiced.
人们对儿童汞合金修复体安全性的担忧日益增加，这导致许多牙科学院重视替代牙科材料的教学。本研究调查了美国博士前儿科牙科项目中后牙不同牙科材料的当前教学情况。2011年，作者邀请了当时所有经认可的牙科学院（=57所）的博士前儿科牙科系主任参加一项基于网络的调查。计算描述性统计数据以描述不同修复材料的使用频率。建立回归模型以探索与博士前儿科诊所牙科修复体使用相关的因素。在回复的44所牙科学院中（回复率为77%），74%使用汞合金，93%在乳后牙中使用复合树脂。61%的学校在乳后牙中使用玻璃离子水门汀。在乳后牙中放置汞合金与治疗更多3至5岁患者的项目相关（β = 0.302，< 0.043），而使用玻璃离子水门汀与学生在异地卫星牙科诊所服务相关（β = 0. : 015，< 0.012）。总体而言，系主任对微创牙科（MID）持积极态度的部门在乳后牙中更频繁地使用复合树脂（β = 0.091，< 0.0001）和玻璃离子水门汀（β = 0.103，< 0.0001），且不太可能使用汞合金（β = -0.077，< 0.005）。尽管牙科学院博士前儿科诊所中微创牙科概念的教学正在增加，但汞合金在乳恒牙后牙中的使用仍然广泛存在。
