Effects of flushing of dental waterlines in portable dental units on water quality management.
Article in Journal of dental sciences, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Background/purpose: Daily flushing of dental unit waterlines is important for infection control. However, the effect of flushing on water quality management in portable dental units (PDUs) for mobile dental treatments remains unclear. In this study, we aimed to investigate the factors affecting the effectiveness of PDU flushing. Materials and methods: Free residual chlorine concentration (FRCC) and heterotrophic plate counts (HPCs) in handpiece discharge water were evaluated as water quality indicators to determine the effectiveness of flushing PDUs, considering flushing duration, periods of PDU use, FRCC in the water used, pre-water drainage in water tanks and waterlines, and season. The effect of flushing on heterotrophic bacterial flora was analyzed by 16S rRNA gene sequencing. Results: PDUs with longer usage periods required a longer flushing duration for FRCC recovery. FRCC reached the standard level for water quality in Japan after at least 20 s of flushing. Flushing changed heterotrophic bacterial flora close to that of fresh tap water by reducing Conclusion: Periods of PDU use, pre-water drainage, water temperature, and FRCC substantially affect the effectiveness of PDU flushing. Flushing for at least 20 s with water containing appropriate free residual chlorine effectively restores the water quality of PDUs.
