Translucency and contrast ratio of dimetharcyrlate resin based dental materials after bleaching: an in-vitro study.
Article in BMC oral health, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveTo compare the translucency and contrast ratio of 13 different resin based restorative materials and to evaluate the effect of 2 different bleaching methods on the translucency and contrast ratio of these materials.
methodsIn this study, a total of 260 samples were prepared, 20 from each of 13 different dimethacrylate-based restorative materials. Then, each material group was divided into 4 subgroups. While two different bleaching methods (home and office) were applied to two of these groups, the other two groups were created as separate control groups for each bleaching group. After the bleaching process, Translucency Parameters (TP) and Contrast Ratio (CR) were calculated with a spectrophotometer. The data obtained were analyzed using two-way ANOVA and Tukey post-hoc tests (p < 0.05).
resultsWhen the bleaching groups were compared in terms of the differences between the TP values in general, it was seen that the TP values decreased in all groups, but this decrease was least in Opalescence PF. In terms of materials, the greatest change in TP and CR values was seen in composite materials, while the least change was seen in hybrid CAD/CAM materials.
conclusionsWithin the limitations of this in vitro study, the effect of bleaching agents on the translucency and contrast ratio of restorative materials depends on the material used and the bleaching method applied. Composite-based materials have been found to be more risky in terms of bleaching. For this reason, the clinician should take this into consideration, especially when performing office bleaching on teeth with restorations.
