客观的。作者进行了一项研究，以确定和量化牙科实践研究网络 (DPBRN) 中的牙医在未修复的恒牙表面上放置修复体的原因以及他们在这样做时使用的牙科材料。方法。共有 229 名 DPBRN 从业者兼研究者提供了有关 5,810 名患者的 9,890 次连续修复体的实践数据。从业者-研究人员提供的信息包括他们修复牙齿的原因、他们修复的具体牙齿和表面以及他们使用的修复材料。结果。原发性龋齿（85% 的牙齿，9,890 颗牙齿中的 8,351 颗）和非龋齿缺陷（15%，9,890 颗牙齿中的 1,479 颗）是参与者放置修复体的主要原因。参与者最常在咬合面上放置因龋齿而需要的修复体（49%，8,351 人中的 4,091 人）。他们在 47% 的磨牙修复体和 45% 的前磨牙修复体中使用了汞合金。他们使用直接放置的树脂基复合材料 (RBC) 进行了 48% 的磨牙修复体、50% 的前磨牙修复体和 93% 的前牙修复体。结论。 DPBRN 实践者和研究人员指出，磨牙咬合面和近端面的龋齿是在之前未修复的牙齿表面上放置修复体的主要原因。红细胞是他们最常用于咬合和前牙修复的材料。尽管作者指出 DPBRN 不同地区的牙医在使用汞合金和 RBC 方面存在显着差异，但汞合金仍然是修复近端龋齿后牙的首选材料。
Objective. The authors conducted a study to identify and quantify the reasons used by dentists in The Dental Practice-Based Research Network (DPBRN) for placing restorations on unrestored permanent tooth surfaces and the dental materials they used in doing so.Methods. A total of 229 DPBRN practitioner-investigators provided data from their practices regarding 9,890 consecutive restorations in 5,810 patients. Information the practitioner-investigators provided included their reasons for restoring the teeth, the specific teeth and surfaces they restored and the restorative materials they used.Results. Primary caries (85 percent of teeth, 8,351 of 9,890) and noncarious defects (15 percent, 1,479 of 9,890) were the main reasons participants gave for placing restorations. Participants placed restorations necessitated by caries most frequently on occlusal surfaces (49 percent, 4,091 of 8,351). They used amalgam for 47 percent of the molar restorations and 45 percent of the premolar restorations. They used directly placed resin-based composite (RBC) for 48 percent of the molar restorations, 50 percent of the premolar restorations and 93 percent of the anterior restorations.Conclusion. DPBRN practitioner-investigators cited dental caries on occlusal and proximal surfaces of molar teeth as the main reasons for placing restorations on previously unrestored tooth surfaces. RBC was the material they used most commonly for occlusal and anterior restorations. Amalgam remains the material of choice to restore posterior teeth with proximal caries, although the authors noted significant differences in the use of amalgam and RBC by dentists in various regions of the DPBRN.
