In vitro assessment of the role of air spray on pulp temperature changes for preheated resin composite Class V restorations in lower incisor.

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
To evaluate the effect of 15- and 30-psi air spray on in vitro pulp temperature (PT) during light-curing of buccal Class V restorations in lower incisors using preheated resin composites (RBCs). After ethical approval, a Class V cavity was prepared in a sound lower central incisor. A T-type thermocouple was inserted into the pulp chamber and connected to a temperature measurement system (Thermes WiFi, Physitemp). Simulated pulpal fluid flow was maintained at a rate of 0.001 mL/min. Real-time PT and working time were recorded during restoration with Viscalor Bulk-fill (VOCO) and Filtek One Bulk-fill (Solventum) preheated to 68 °C. Air spray (15 or 30 psi) was directed to the lingual surface, starting 3 s before and maintained throughout light-curing (n = 9). Vickers hardness (VHN) was measured at the middle and inner surfaces near the top and bottom of each specimen. PT and VHN data were analyzed using nonparametric mixed ANOVA, and working time was analyzed using nonparametric two-way ANOVA, both followed by Bonferroni's post hoc tests (α = 0.05). Light-curing of preheated RBCs significantly increased PT (42.5 ± 1.3 °C; p < 0.001). Air spray at 15 and 30 psi reduced PT values (28.4 ± 1.3 °C and 26.8 ± 1.8 °C, respectively; p < 0.001) without affecting VHN values. Air spray during light-curing effectively minimized pulp temperature rise during restorative procedures using preheated RBCs on lower incisors.
