Effect of Moving the Tip of the Light Curing Unit on the Irradiance Value Delivered.
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 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 determine the effect of differences in the distances and radial positions of the tips of Light-Curing Units (LCU) on the irradiance values delivered. MATERIALS AND
methodsFour LCUs-Valo X, Emitter A, CuringPen, and Pinkwave were tested at different distances from the tip (0, 2, 4, 6, 8 mm) and radial displacements (2 and 4 mm East, West, North, South). The radiant power (mW) and emission spectrum (mW/nm) were measured using an integrating sphere with a 4 mm aperture. Calibrated irradiance beam profiles were recorded across the tip using a laser beam analyzer. Data were analyzed with a two-way ANOVA at a significance level of 5%.
resultsRadial displacement significantly reduced the irradiance values delivered from all four LCUs (p < 0.05). At 4 mm, the mean irradiance value was below 1000 mW/cm
conclusionVariations of 2 or 4 mm in the radial tip position negatively affected irradiance values from the LCUs tested. CLINICAL SIGNIFICANCE: The radial position and LCU choice can significantly affect the irradiance delivered.
