Effect of Dentin Pretreatment With Dimethyl Sulfoxide Solution on Interfacial Fracture Toughness of Composite Resin to Wet and Dry Dentin.

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
Objectives: This study aimed to investigate the effect of dentin pretreatment with dimethyl sulfoxide (DMSO) on the interfacial fracture toughness (IFT) of composite resin bonded to dentin under varying collagen hydration conditions, addressing conflicting findings in existing literature. Methods and Materials: A total of 84 dentin samples were randomly assigned to six groups based on the following variables: initial collagen hydration condition (wet or dry), dentin pretreatment (DMSO/ethanol or control), and collagen moisture condition prior to hybridization as follows: (1) Wet dentin control (no pretreatment, blot-dried), (2) Wet dentin + DMSO/EtOH pretreatment (blot-dried), (3) Wet dentin + DMSO/EtOH pretreatment (air-dried), (4) Dry dentin control (no pretreatment, air-dried), (5) Dry dentin + DMSO/EtOH pretreatment (blot-dried), and (6) Dry dentin + DMSO/EtOH pretreatment (air-dried). A two-step etch-and-rinse (E&R) bonding technique was utilized. After bonding, samples were stored in distilled water for 24 h and subjected to 3000 thermocycling cycles. IFT was measured, and fracture patterns were analyzed using stereomicroscopy and scanning electron microscopy (SEM). Statistical analysis employed ANOVA at a significance level of 0.05. Results: The average IFT revealed significant differences between initial dentin conditions ( Conclusions: The DMSO/EtOH solution, used as a dentin pretreatment, positively affected the IFT of composite resin, particularly for wet dentin surfaces.
