Effect of Different Matrix Metalloproteinase Inhibitors on the Shear Bond Strength of Composite Attached to Dentin: An In Vitro Study on Permanent Teeth.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
aimThis study aimed to evaluate the effect of various matrix metalloproteinase (MMP) inhibitors on the shear bond strength (SBS) of composite resin to dentin in permanent teeth using an etch-and-rinse adhesive system and the pairwise comparative analysis between each MMP inhibitor group and the control group. MATERIALS AND
methodsDentin blocks were prepared from 60 permanently extracted molars and were randomly distributed into four groups (each group, n = 15). The dentinal blocks were pretreated with 0.01M phosphate-buffered saline (PBS) (pH 7.2) in the control group (Group I), 2% chlorhexidine (CHX) (Group II), Gluma desensitizer (Kulzer, Germany) (Group III), and 6.5% proanthocyanidin (Group IV) before applying the etch and rinse adhesive system (Ivoclar, Switzerland). After the adhesive application, composite resin (Kulzer, Germany) was applied, and after seven days, the SBS values were determined with a Universal Testing Machine (Zwick/Roell Z020, ZwickRoell Group, Germany).
resultsThere was a significant difference in the SBS values of Gluma desensitizer, 2% CHX, 6.5% proanthocyanidin, and the control group (P < 0.05). The Gluma desensitizer group showed the highest bond strength values (mean 12.98 MPa), which were significantly greater than those of all the other groups.
conclusionsUnder the experimental conditions of this study, pretreatment with MMP inhibitors was advantageous in improving the SBS of the composite attached to permanent teeth dentin, with Gluma being most effective.
