Enamel Deproteinization with Sodium Hypochlorite: Effects on Ceramic Bracket Bond Strength.
Article in Brazilian dental journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
To assess the efficiency of different concentrations of sodium hypochlorite (NaOCl) on the bonding of ceramic brackets to dental enamel using different bonding protocols. Ceramic, a polycrystalline bracket, was bonded to 90 extracted bovine incisors using primer + Transbond XT (P+TXT); Optibond S adhesive + Transbond XT (OS+TXT), and OS + Orthocem (OS+OC). Three concentrations of NaOCl (0%, 2.5%, and 5.25%) were used for each material, resulting in nine experimental groups (n=10). The shear bond strength (SBS) assay was performed on a universal testing machine. The surface morphology of the enamel and tooth/bonding material interface was examined under a scanning electron microscope. Kruskal-Wallis and Dunn's tests were performed to compare the non-parametric data (ARI scores). SBS data were analyzed using a generalized linear model. All analyses were performed using the R program and with a significance level of 5%. No significant differences in SBS between the groups with different concentrations of NaOCl (p>0.05). OS+OC group yielded the lowest bond strength values (3.35 MPa_0%, 4.90 MPa_2.5%, 4.68 MPa_5.25%) compared to the other groups, regardless of NaOCl (p<0.05). No significant difference between the materials regarding the ARI score (p>0.05). OS+TXT-5.25% showed significantly higher scores (14.4 MPa) than OS+TXT-2.5% (9.17 MPa) (p<0.05). The surface morphology analysis revealed a change in the etching pattern for types 1 and 2 when NaOCl was used. The different concentrations of NaOCl previously applied onto the enamel surface did not enhance bond strength. OS+OC should not be recommended for bonding with fixed ceramic orthodontic devices.
