Effect of Three Heating Guns on the Temperature of Two Bulk-Fill Resin-Based Composites.
Article in Journal of esthetic and restorative dentistry : official publication of the American Academy of Esthetic Dentistry ... [et al.], 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveTo evaluate the effect of three heating guns-Phasor (Vista Apex, Racine, USA), VisCalor (VOCO, Cuxhaven, Germany), and Compex HD (AdDent Inc. Danbury, USA)-on the temperature changes of two bulk-fill resin-based composites (RBCs): VisCalor Bulk (VBF, VOCO) and Filtek One Bulk Fill Restorative (OBF, Solventum, St. Paul, USA). MATERIALS AND
methodsTemperature changes were measured using a thermal camera (PI 640i, Optris Infrared Measurements, Berlin, Germany) during insertion and photocuring in a simulated proximal box of a Class II cavity and within the RBC capsules during heating. The RBCs were photocured using the Bluephase PowerCure (Ivoclar, Schaan, Liechtenstein) for 20s. Data were analyzed using repeated measures ANOVA and Tukey's test for each RBC (α = 0.05). The temperature of the RBCs at the same depth were analyzed by t-test (α = 0.05).
resultsOBF heated with Compex produced the lowest temperature rise at the pulpal floor (2.7°C ± 0.4°C), while VBF heated with Phasor produced the highest (8.8°C ± 2.4°C). The greatest temperature increases were at the top of the restoration. OBF heated with Phasor reached 48.6°C ± 4.7°C. The Phasor and VisCalor produced two temperature peaks in the RBC inside the capsule, while the Compex maintained a steady peak temperature.
conclusionThe heating gun and RBC produced different temperatures when heating, inserting, and light-activation of the RBCs. CLINICAL SIGNIFICANCE: The choice of RBC and heating gun can substantially affect the temperature of the RBC and influence its handling properties.
