Evaluation of the effect of etching with ytterbium fiber laser on the bond strength, color stability, and fracture analysis of lithium disilicate ceramics to bovine teeth: an in vitro study.

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
purposeThis study aimed to investigate the impact of 1070 nm Ytterbium Fiber Laser (YFL) on the shear bond strength of lithium disilicate ceramics to enamel.
methodsFifty-four freshly extracted bovine teeth were embedded in acrylic resin, with labial surfaces exposed. The teeth underwent etching with phosphoric acid, followed by the application of bond resin. Ceramic samples of 0.5 mm, 1 mm, and 1.5 mm thickness were obtained from lithium disilicate CAD blocks using a precision cutting tool. Samples were divided into two subgroups according to surface treatment method: one group was treated with 4.5% hydrofluoric acid for 20 s, while the other was treated with a 20 W average power YFL. One sample from each subgroup underwent SEM analysis; the remaining samples were cemented to prepared bovine teeth using composite resin cement. Color measurements were performed before and after surface treatments. Shear bond strength was evaluated using a universal testing machine with a crosshead speed of 0.5 mm/min. Fracture analyses were conducted using a stereomicroscope. Statistical analyses were performed using two-way ANOVA and two-way ANOSIM.
resultsAccording to the two-way ANOVA results, the ΔE
conclusionThe shear bond strengths of lithium disilicate ceramics, whether treated with YFL or hydrofluoric acid, were found to be comparable. These findings suggest the potential utility of 1070 nm YFL for ceramic etching, supporting the need for further investigation in dental applications.
