Mechanical and optical effects of post-curing time and device type in two 3D-printed resin systems.
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 7 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
aimThe aim of this study was to investigate the effect of post-polymerization time and curing device type on the surface roughness, microhardness and color change of 3D printed permanent resin materials. MATERIALS AND
methodsIn this study, permanent resin samples with a layer print thickness of 50 μm and dimensions of 10 × 2 mm3 were produced on SLA and DLP printers. The samples were post-polymerized in blue LED and UV LED curing devices for 10, 20, 40 and 60 min. Initial surface roughness, microhardness and color values of all polymerized samples were measured. The samples were then aged (5000 cycles) and surface roughness, microhardness and color values were measured again. Data were evaluated using two-way analysis of variance (ANOVA) and Tukey post hoc test (p < 0.05).
resultsThere was no statistically significant difference in surface roughness when the samples produced in SLA and DLP printer were polymerized using blue LED and UV LED curing device for different durations (p > 0.05). The samples produced in SLA printer showed higher microhardness value when polymerized with UV LED for longer time (p < 0.05). There was no statistically significant difference in the microhardness values of DLP samples when polymerized with blue LED and UV LED (p > 0.05). When the samples produced in SLA and DLP printer were polymerized using blue LED and UV LED curing device for different durations, the color change and whiteness index increased as the post-polymerization time increased (p < 0.05). The surface roughness of the samples after aging did not change statistically significantly, while the microhardness value decreased (p < 0.05).
conclusionsThe post-polymerization time and the type of polymerization device do not affect the surface roughness of the 3D printed samples, but increase the microhardness value. Post-polymerization time increases the color change and whiteness index values of the samples. Post-polymerization of 3D printer permanent resin materials has an effect on the mechanical and optical properties of the material. CLINICAL SIGNIFICANCE: The post polymerization time of 3D resin materials and the type of curing device change the microhardness, color change and surface roughness of the material. This may affect the clinical success of the restoration.
