Effects of 810 nm diode laser irradiation on the micro tensile bond strength of uncured multi-mode dentin bonding agents.

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 study aimed to evaluate the effect of 810 nm diode laser irradiation on the microtensile bond strength (µTBS) of multi-mode dentin bonding agents to dentin. 48 premolars were assigned to six groups to determine the µTBS (n = 16). In the control groups, universal adhesives namely Scotchbond Universal, G-Premio, and Ambar Universal were used on dentin. In the experimental groups diode laser (810 nm,1W power) was irradiated for 10 s on unpolymerized adhesive. The adhesive was light-cured and the tooth was restored with composite. After 500 thermal cycles (5-55 °C), the µTBS test was performed at 0.5 mm/min. Data were analyzed by two-way ANOVA and post-hoc Tukey's tests (α = 0.05). One extra tooth per group was used to assess the thermal changes during the light-curing on dentin, laser irradiation, adhesive and composite light curing. Six additional teeth were used to assess the micro-morphology of the resin-dentin interface by scanning electron microscopy (SEM). Specimens were evaluated under a stereomicroscope (× 40) to determine the failure mode. The µTBS was significantly higher in the laser groups (P < 0.05). The maximum and minimum µTBS were recorded in G-Premio + laser (GBL) (19.91 ± 3.0 Mpa) and Ambar Universal + laser (ABL)(11.71 ± 3.0 Mpa) groups, respectively. The dominant failure mode was adhesive in the control groups and mixed in the laser groups. The temperature rise during laser irradiation (2.2 °C) was lower than the temperature rise during adhesive and composite light curing (4.1 °C and 7.5 °C, respectively). Irradiation of unpolymerized universal adhesive systems with 810 nm diode laser with 1 W power for 10 s increased the µTBS of composite to dentin.
