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.

Abstract
backgroundThe durability of bonded CAD/CAM restorations depends largely on effective adhesion to dentin. Immediate dentin sealing (IDS) has been proposed to enhance bonding effectiveness compared with conventional delayed dentin sealing (DDS). Additionally, while resin cements remain the gold standard for luting, flowable composites have emerged as potential alternative. This study aimed to evaluate the effect of different dentin sealing techniques and luting materials on the microtensile bond strength (µTBS) of CAD/CAM composite disc to dentin after immediate and long-term aging.
methodsTwenty flat dentin specimens were obtained from extracted human molars and randomly assigned to two main groups according to the dentin sealing techniques into (group 1: No-IDS and group 2: IDS with a universal adhesive). The two groups were provisionally restored with temporary materials for two weeks. Afterwards the temporary materials were removed, and surface was reactivated with air borne abrasion. Each group was subdivided according to the luting material used for CAD/CAM composite discs into (subgroup 1: dual-cure self-adhesive resin cement and subgroup 2: submicron hybrid flowable composite). The specimens were sectioned into micro-bars and tested for µTBS either after 48 h (immediate) or 6 months (long-term aging) in water storage. Data were analyzed using three-way ANOVA and post-hoc comparisons (α = 0.05). Failure modes were analyzed.
resultsImmediate µTBS values displayed no significant differences among the tested groups. Following long-term aging, IDS combined with a flowable composite yielded significantly higher µTBS compared to groups without IDS. Furthermore, the flowable composite demonstrated significantly higher bond strength than the self-adhesive resin cement, regardless of the dentin sealing protocol used.
conclusionsThe microtensile bond strength of CAD/CAM composite to dentin is dependent on both the dentin sealing technique and the luting material. Immediate dentin sealing combined with a submicron hybrid flowable composite demonstrated the highest bond strength after long-term aging, compared to the tested self-adhesive resin cement. The effect of artificial aging was highly material-dependent; therefore, long-term aging is necessary to accurately evaluate the bond durability.
