Evaluation of thermal rise on simulated pulp tissue during light-cured direct capping in vitro: an artificial microcirculation study.
Article in BMC oral health, 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
backgroundTo evaluate the temperature values including initial, maximum, and rising caused by light-cured materials used for direct capping during polymerisation.
methodsA 3 mm deep, wide, and length class-I cavity was prepared to a premolar tooth, leaving hard tissue at the pulpal floor of 1 mm thickness with a 1 mm diameter of exposure. The sample was placed in a customised mimicry setup in which the temperature was standardised (37 °C) by a double-verified system. Light-curing capping materials (Theracal LC, Theracal PT, Harvard BioCal, and Ultrablend Plus) were placed, polymerised, and temperature values were recorded. Kruskal-Wallis test was used to compare parameters among groups, and Dunn's test was used to define the group that caused the difference (p < 0.05).
resultsThere were statistically significant differences between the materials in terms of initial, maximum, and temperature rising values (p
conclusionsTheracal PT caused higher temperature rise, however, it did not exceed 5.6 °C, which is the critical value for the pulp. Theracal PT should be used with caution as its use during direct capping causes high temperature increases, and there is a need for a light-curing regime to be designed for its use.
