The effect of storage conditions and duration on dimensional stability of 3D-printed endoguides.
Article in BMC oral health, 2025. 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
backgroundThis study evaluated the dimensional stability and angular deviations of 3D-printed endodontic guides under varying storage conditions (wet vs. dry, dark vs. daylight) and durations (7 vs. 14 days).
methodsEndodontic guides for the localization of obliterated canals were designed using BlueSkyPlan software (BlueSky Bio, IL, USA) and printed with Biomed Clear Resin V2 (Formlabs Inc., Somerville, USA) via SLA technology. A total of 40 endodontic guides were fabricated and divided into four groups (n = 10), each subjected to either light or dark storage conditions for durations of 7 or 14 days. Dimensional stability was assessed using root mean square (RMS) and angular deviations in Geomagic Design X (Oqton, USA). Statistical analyses were performed using IBM SPSS v29 with independent samples and paired t-tests (p = 0.05).
resultsGuides stored in dry conditions had lower RMS (0.052 ± 0.013) and angular deviations (0.29 ± 0.11) than wet conditions (RMS: 0.069 ± 0.028, p = 0.001; angle: 0.36 ± 0.11, p = 0.008). Angular deviations increased at 14 days (p = 0.003). Daylight exposure increased RMS deviations at 14 days in dry conditions (p = 0.001). Wet storage in dark conditions led to greater deviations at both time intervals(p < 0.05).
conclusionsStorage conditions and duration significantly affect the dimensional stability of 3D-printed endodontic guides. Wet storage and prolonged duration reduce accuracy. To maintain precision, guides should be used within 7 days and stored in dry, dark environments. CLINICAL TRIAL NUMBER: Not applicable.
