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
objectiveThis study evaluated dentin morphology and pulp cavity temperature changes during nanosecond‑ and microsecond‑pulse Er, Cr: YSGG laser debonding restoration and residual adhesive. MATERIALS AND
methodsTen caries-free teeth had their enamel removed perpendicular to the long axis, followed by bonding of glass ceramic restorations. The samples were randomly divided into two groups and subjected to Er, Cr: YSGG laser (3 mJ, 100 Hz, 100 ns), (3 mJ, 100 Hz, 150 µs) for debonding of restoration and residual adhesive on dentin surfaces. Thermocouples and scanning electron microscopy were used to monitor pulp cavity temperature and dentin surface morphology during debonding.
resultsBoth nanosecond- and microsecond-pulse lasers effectively debonding restorations, leaving residual adhesive on dentin surfaces that required further treatment. The temperature change of pulp cavity with nanosecond pulses laser was 1.8 ℃ and 2.8 ℃ during debonding of restoration and residual adhesive, and with microsecond pulses were also 3.4 ℃ and 5.8 ℃, respectively. The dentinal tubules in the nanosecond pulses laser group were completely opening, while those in the microsecond pulses laser group were partially opening.
conclusionsNanosecond pulses of Er, Cr: YSGG laser are preferable over microsecond pulses for debonding restoration and residual adhesive on dentin surfaces. Nanosecond pulses induce smaller temperature changes in the pulp cavity and more pronounced opening of dentinal tubules, facilitating subsequent bonding processes.
