In vitro changes in pulpal temperature during light exposure at different pulpal fluid flows.
Article in Odontology, 2026. 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
This in vitro study evaluated the effect of three different fluid flow rates on the pulp temperature (PT) of an empty Class II cavity using three high-powered light-curing units (LCUs): Bluephase PowerCure (Ivoclar Vivadent), PinkWave (Vista Apex), and Valo X (Ultradent), using both 10 s (normal) and their highest irradiance, shortest exposure modes. The spectral radiant power, irradiance, and radiant exposure delivered from each LCU were measured using an integrating sphere. A T-type thermocouple was placed inside the pulp chamber of a human molar with a Class II cavity. Three different pulpal flow rates were evaluated: 0.026 mL/min, 0.2 mL/min and 1 mL/min. After reaching a baseline of 32 °C, PT measurements were recorded every 0.5 s before, during and after light exposure (n = 5). The temperature increases (ΔT) for the different light conditions at the different fluid flow rates were analyzed using ANOVA followed by the Tukey post hoc tests (⍺ = 0.05). No significant changes in PT were found between pulpal fluid flow rates of 0.026 mL/min and 0.2 mL/min, but there was a lower PT when the pulp fluid flow was increased to 1 mL/min. The LCUs produced different ΔT. The PT rise was directly associated with the radiant exposure (J/cm
