The Effect of Time Pressure on the Quality of Fillings and Arousal Levels of Dentists.
Trial report in Clinical and experimental dental research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesWe 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
methodsForty-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.
resultsTime 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 (X
conclusionsEmploying 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.
