Effect of surface treatment on glass ionomers in sandwich restorations: a systematic review and meta-analysis of laboratory studies.
Article in Restorative dentistry & endodontics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Objectives: This study aimed to evaluate the effect of different surface treatments on the bond strength between new or aged glass ionomers (GI) and resin composites in sandwich restorations. Methods: A comprehensive search was conducted in three databases to identify studies focusing on the bond strength of new or aged GIs and resin composites in laboratory settings. The selected studies were assessed for potential biases based on predetermined criteria. Additionally, a meta-analysis was performed using three studies. Results: A total of 29 studies were included, with 24 investigating the bond strength of new GIs and five focusing on GI repair. Three studies were included in the meta-analysis (with a 95% confidence interval) which revealed no significant difference in the mean MPa values of resin-modified glass ionomer (RMGI) treated with phosphoric acid or Er,Cr:YSGG laser before the application of an etch-and-rinse adhesive. Surface treatment was found to be crucial for achieving optimal bonding between GI and resin composite, regardless of the GI's condition. Conclusions: The combination of mechanical and chemical surface treatments does not significantly affect the bond strength between new RMGI and composite. However, for GI repair, it is recommended to use both treatments to enhance the bond strength.
