Shear Bond Strength and Enamel Effects of Bioactive Composite Attachments for Clear Aligners.
Review in Journal of clinical and experimental dentistry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
Background: Attachments improve retention and facilitate complex tooth movement during clear aligner therapy. However, enamel demineralization and white spot lesions remain concerns, particularly in patients with poor oral hygiene. Fluoride-releasing materials help prevent white spot lesions, and bioactive composites, which release fluoride ions, show promise in preventing demineralization while maintaining strong mechanical properties. However, their application in clear aligner therapy remains underexplored. Therefore, this study investigated the shear bond strength (SBS) of three materials-Filtek Z350 XT Flowable (resin composite), Beautifil Injectable X (giomer), and Cention N (bioactive composite) used as attachments in clear aligner therapy under non-thermocycling (T0) and thermocycling (T1) conditions. Material and Methods: A total of 120 intact maxillary first premolars were randomly divided into three groups according to the material, with each further subdivided into T0 and T1 subgroups. The thermocycling protocol involved 1,000 cycles between 5°C and 55°C to simulate intraoral aging. SBS was tested using a universal testing machine, and failure modes were analyzed with the adhesive remnant index (ARI). Results: Cention N exhibited the highest SBS (29.783 ± 4.741 MPa), followed by Filtek Z350XT Flowable (23.834 ± 4.708 MPa), while Beautifil Injectable X had the lowest (15.332 ± 4.087 MPa). The SBS was slightly higher in the T0 subgroup than in the T1 subgroup, but the difference was not significant. ARI analysis showed that Cention N was more likely to cause cohesive enamel failure during attachment detachment. Conclusions: All three materials demonstrated adequate SBS for use as attachments in clear aligner therapy. However, material selection should consider both SBS and potential risks to enamel integrity. These findings provide valuable data for optimizing material choices in clear aligner therapy and highlight the need for further research to assess long-term performance.
