摘要
目的在模拟临床环境下，采用两种充填技术，研究时间压力对牙医觉醒水平和复合树脂充填质量的影响。材料与方法将42名牙医和牙科学生随机分为两组，一组采用填充基体技术，另一组采用常规增量技术。任务先在定时条件下完成，然后在时间压力下完成。唤醒水平通过100毫米视觉模拟量表（VAS）和腕部无线三轴加速度计进行研究。采用体视显微镜和专用探针，根据FDI修复评价标准对充填体的表面孔隙度和边缘间隙进行评价。结果时间压力显著提高了被试的唤醒水平（F = 14.98, p < 0.05），实验组对时间压力下被试的唤醒水平有显著影响（F = 7.78, p < 0.05）；Dunn-Bonferroni测试表明，与传统的增量技术（M = 6.68, SD = 1.86）相比，散装填充技术（M = 4.53, SD = 2.17）的唤醒水平显著降低（p < 0.05）。在时间压力下，砌块充填法的修复效果较好（X2 = 4.71, p = 0.030）。经验不足的操作人员使用填充基体技术获得了更好的质量（Χ2 = 5.62, p = 0.018），而操作人员的经验与时间压力下的唤醒水平无关。结论在时间压力下采用体基体充填技术可降低操作人员的兴奋水平，提高充填的即时质量。在不影响补牙质量的前提下，块状充填基体技术有望抵抗牙科中常见的工作环境因素，如时间压力和压力。在临床环境中利用创新技术，如大块填充基础技术，有助于减轻操作人员的压力，提高所提供的护理质量。
The Effect of Time Pressure on the Quality of Fillings and Arousal Levels of Dentists
Objectives
We investigated the impact of time pressure on dentists' arousal levels and the immediate quality of composite resin fillings using two filling techniques in a simulated clinical setting.
Material and Methods
Forty-two dentists and dental students were randomized to fill an identical Class II cavity either with the bulk-fill base technique or the conventional incremental technique. The task was performed first under timing and then under time pressure. Arousal levels were investigated with a 100 mm visual analog scale (VAS) and a wireless wrist-mounted triaxial accelerometer. The surface porosity and marginal gaps on the approximal surfaces of the fillings were evaluated using a stereomicroscope and specific probes according to the FDI criteria for restoration evaluation.
Results
Time pressure significantly increased arousal overall (F = 14.98, p < 0.05), and there was a significant effect of the experimental group on participants' arousal levels under time pressure (F = 7.78, p < 0.05); Dunn–Bonferroni tests indicated significantly lower arousal levels (p < 0.05) for the bulk-fill base technique (M = 4.53, SD = 2.17) compared to the conventional incremental technique (M = 6.68, SD = 1.86). The bulk-fill base technique showed superior quality under time pressure (X2 = 4.71, p = 0.030). Less experienced operators achieved better quality with the bulk-fill base technique (Χ2 = 5.62, p = 0.018), while operator experience did not correlate with arousal levels under time pressure.
Conclusions
Employing the bulk-fill base technique under time pressure led to reduced operator arousal levels and improved the immediate quality of fillings.
Clinical Relevance
The bulk-fill base technique shows promise in being resistant to common work environment factors in dentistry, such as time pressure and stress, without compromising the quality of fillings. Utilizing innovative techniques, such as the bulk-fill base technique, in a clinical setting can contribute to mitigating the operator's stress and enhancing the quality of care provided.
期刊介绍：
Clinical and Experimental Dental Research aims to provide open access peer-reviewed publications of high scientific quality representing original clinical, diagnostic or experimental work within all disciplines and fields of oral medicine and dentistry. The scope of Clinical and Experimental Dental Research comprises original research material on the anatomy, physiology and pathology of oro-facial, oro-pharyngeal and maxillofacial tissues, and functions and dysfunctions within the stomatognathic system, and the epidemiology, aetiology, prevention, diagnosis, prognosis and therapy of diseases and conditions that have an effect on the homeostasis of the mouth, jaws, and closely associated structures, as well as the healing and regeneration and the clinical aspects of replacement of hard and soft tissues with biomaterials, and the rehabilitation of stomatognathic functions. Studies that bring new knowledge on how to advance health on the individual or public health levels, including interactions between oral and general health and ill-health are welcome.
