The Dental Practice-Based Research Network (DPBRN) provided a means to investigate whether certain procedures were performed routinely. The authors conducted a study to quantify rubber dam use during root canal treatment (RCT) among general dentists and to test the hypothesis that certain dentist or practice characteristics were associated with rubber dam use.
DPBRN practitioner-investigators (P-Is) answered a questionnaire that included items about rubber dam use and other forms of isolation during RCT. DPBRN enrollment questionnaire data provided information regarding practitioner and practice characteristics.
A total of 729 (74 percent) of 991 P-Is responded; 524 were general dentists who reported providing at least some RCTs and reported the percentage of RCTs for which they used a rubber dam. Of these 524 P-Is, 44 percent used a rubber dam for all RCTs, 24 percent used it for 51 to 99 percent of RCTs, 17 percent used it for 1 to 50 percent of RCTs, and 15 percent never used it during RCT. Usage varied significantly by geographic region and practice type. The use of cotton rolls and other forms of isolation also was reported.
Similar to other reports in the literature, not all DPBRN general dentists used a rubber dam during RCT.
Because the clinical reference standard is to use a rubber dam during RCT, increasing its use may be important.
口腔实践为基础的研究网络（DPBRN）为研究某些程序是否常规执行提供了一种手段。作者进行了一项研究，以量化普通牙医在根管治疗（RCT）中使用橡皮障的情况，并检验牙医或实践特征与使用橡皮障之间存在关联的假设。
DPBRN 从业者调查员（P-Is）回答了一份问卷，其中包括关于橡皮障使用以及 RCT 期间其他隔离形式的项目。DPBRN 注册问卷数据提供了有关从业者和实践特征的信息。
共有 991 名 P-Is 中的 729 名（74%）做出了回应；其中 524 名为提供至少部分 RCT 并报告其使用橡皮障的 RCT 百分比的普通牙医。在这 524 名 P-Is 中，44%的牙医在所有 RCT 中都使用橡皮障，24%的牙医在 51%至 99%的 RCT 中使用橡皮障，17%的牙医在 1%至 50%的 RCT 中使用橡皮障，15%的牙医在 RCT 中从不使用橡皮障。使用情况因地理位置和实践类型而异。也报告了使用棉卷和其他隔离形式。
与文献中的其他报告类似，并非所有 DPBRN 普通牙医在 RCT 中都使用橡皮障。
由于 RCT 中使用橡皮障的临床参考标准，因此增加其使用可能很重要。
