Comparative Evaluation of Nanosized Intracanal Medicaments on the Penetration and Fracture Resistance of Root Dentin: An In Vitro Study.

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
introductionThe use of calcium hydroxide (CH) is crucial in the proper disinfection of root canals. However, CH affects the fracture resistance of root dentine and also has limited permeability. Nano-based intracanal medicaments have several benefits over traditional medicaments, including a greater surface area-to-volume ratio and better penetrability. Therefore, this in vitrostudy was performed to evaluate and compare the effect of conventional CH and various nanoparticle-based intracanal medicaments on the penetration and fracture resistance of radicular dentin. MATERIALS AND
methodsOne hundred samples were taken and randomly divided into four (n=20) experimental groups (nano-CH (NCH), nano-chitosan (NCS), NCH + nano-silver (NAg), NCS + NAg, and a control group (CH). At the end of one month, out of the 20 samples from each group, 10 samples were used to assess the fracture resistance in a universal testing machine, and the other 10 samples were used to determine the depth of penetration using a field emission scanning electron microscope.
resultsThe mean fracture resistance of root dentin value was the highest with group II (NCS) and the least in the control group (CH), which was statistically significant. The maximum penetration depth of intracanal medicaments was observed with group III (NCH + NAg) and the least in the control group (CH), which was statistically significant. Among the thirds of the root samples, the highest mean depth of penetration was seen in the coronal third and the least in the apical third in all the groups, which was statistically significant.
conclusionThe resistance to fracture and penetration depth at a four‑week interval were higher in nano forms when compared with conventional CH.
