Introduction Clinicians' use, interpretation and application of evidence in everyday practice is fundamental to their delivery of appropriate, contemporary, high-quality dentistry. Little is known about whether new dental graduates' (NDGs') perspectives and use of evidence-based practice (EBP) change when they enter professional practice.Aim To explore changes in NDGs' perception of EBP for: self-efficacy; knowledge of EBP principles; attitudes; confidence in appraisal skills; and frequency of accessing evidence.Methods Two pre-validated instruments: knowledge, attitude, confidence and accessing EBP resources, EBP confidence scale, and clinical scenarios. NDGs from one dental school completed the questionnaire upon graduation (R1) and six to nine months into vocational dental training (R2).Results Response rates of R1 were 34 (52%) and R2, 21 (62% of R1, 32% overall). Between R1 and R2, knowledge (median [25th-75th percentiles]: R1 = 4 [2.5-4]; R2 = 3 [2.8-3], p = 0.07), self-efficacy (R1 = 645 [587-782]; R2 = 630 [550-690], p = 0.8) and scores related to knowledge of gold standards were comparable. However, attitude (R1 = 38 [34-39], R2 = 27 [25-30]), confidence in appraisal skills (R1 = 16 [14-20], R2 = 11[8-16]) and frequency of accessing evidence (R1 = 26 [22-28]; R2 = 18 [16-19]) all showed statistically significant reductions.Conclusion After six months in professional practice, NDGs showed statistically significant reductions in the value they place on EBP, their EBP-related skills and their use of reliable evidence sources. There were no differences in their 'self-efficacy' knowledge of EBP principles.
引言
临床医生在日常实践中对证据的使用、解读和应用对于提供恰当、现代、高质量的牙科治疗至关重要。对于刚毕业的牙科学生（NDGs）在进入专业实践后，他们对循证实践（EBP）的看法和使用情况是否会发生变化，我们知之甚少。
目的
探讨NDGs在以下方面对EBP认知的变化：自我效能感；EBP原则知识；态度；评估技能信心；以及获取证据的频率。
方法
知识、态度、信心和获取EBP资源、EBP信心量表以及临床情景。来自一所牙科学院的NDGs在毕业时（R1）以及进入牙科职业培训6至9个月后（R2）完成问卷。
结果
R1的回复率为34（52%），R2的回复率为21（占R1的62%，总体的32%）。在R1和R2之间，知识（中位数[第25 - 75百分位数]：R1 = 4[2.5 - 4]；R2 = 3[2.8 - 3]，p = 0.07）、自我效能感（R1 = 645[587 - 782]；R2 = 630[550 - 690]，p = 0.8）以及与金标准知识相关的得分具有可比性。然而，态度（R1 = 38[34 - 39]，R2 = 27[25 - 30]）、评估技能信心（R1 = 16[14 - 20]，R2 = 11[8 - 16]）和获取证据的频率（R1 = 26[22 - 28]；R2 = 18[16 - 19]）均显示出统计学上的显著下降。
结论
在专业实践六个月后，NDGs在对EBP的重视程度、与EBP相关的技能以及对可靠证据来源的使用方面均显示出统计学上的显著下降。他们在EBP原则的“自我效能感”知识方面没有差异。
