Repair bond strength of composite resin to additively manufactured permanent resin materials: a comparative evaluation of light-cure, self-cure, and dual-cure universal adhesives.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundThis study aimed to evaluate the repair bond strength of composite resin to two 3D-printed permanent resin materials using different universal adhesive systems-light-cure, self-cure, and dual-cure-following a standardized air abrasion.
methodsSeventy-two disc-shaped specimens (n = 12 per group) were fabricated using two different commercial 3D-printed materials: Saremco Crowntec and Bego VarseoSmile Crown Plus. After post-processing, all specimens were thermocycled for 5,000 cycles to simulate aging. The bonding surfaces were then subjected to air abrasion, followed by the application of one of three universal adhesive systems: light-cure (G-Premio Bond), self-cure (Tokuyama Universal Bond II), or dual-cure (Futurabond U). A composite resin (Filtek Z250) cylinder was then bonded and light-cured. Shear bond strength (SBS) was measured, and fracture modes were examined under a stereomicroscope. Data were analyzed using two-way analysis of variance (ANOVA) and Tukey HSD tests (p < 0.05).
resultsSelf-cure universal adhesives exhibited the highest SBS values, especially in the Bego material group (19.20 ± 2.11 MPa), while the lowest bond strength was observed in the Saremco + light-cure group (14.28 ± 1.23 MPa). Both the adhesive system (p < 0.001) and material type (p = 0.002) significantly affected SBS. Failure mode analysis revealed predominantly adhesive failures in the light-cure groups, and more mixed/cohesive failures in the self-cure and dual-cure groups.
conclusionsBond strength of repaired 3D-printed permanent resins is significantly influenced by the adhesive systems and material type. Self-cure universal adhesives provided the most effective bonding performance, particularly when combined with Bego VarseoSmile Crown Plus.
