Biophysical properties and antimicrobial efficacy of a novel Silk Sericin Mineral Trioxide Aggregate.

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: Mineral Trioxide Aggregate (MTA) is widely used in endodontics due to its excellent biocompatibility and sealing abilities. However, complete eradication of bacteria from the root canal remains challenging. Currently available materials cannot ensure a complete hermetic seal and antimicrobial properties, which are essential to prevent reinfection. This study aimed to develop a novel Mineral Trioxide Aggregate combined with silk sericin and to evaluate its biophysical properties and antimicrobial efficacy against oral pathogens. Methods: Lyophilized silk sericin powder was mixed with MTA in a 1:1 ratio. Silk sericin-MTA Conjugate (SC), Silk sericin (SS), and MTA were evaluated for their biophysical properties using Attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy, x-Ray diffraction, atomic force microscopy, and circular dichroism. The antimicrobial efficacy was evaluated against Staphylococcus Results: ATR-FTIR spectroscopy revealed distinctive peaks, confirming the structural modifications of the Sericin-MTA conjugate. x-ray diffraction revealed that all groups exhibited a lattice structure and were found to be crystalline in nature. However, in atomic force microscopy, MTA appeared to have a flat and uniform surface, while Sericin-MTA conjugate showed shallow depressions across its surface. The circular dichroism revealed the typical properties of silk protein, which is mainly composed of α-helical structures in Sericin-MTA conjugate. The antimicrobial activity was observed in the order of MTA < SC < SS. Conclusions: This research provides concrete evidence that the innovative combination of MTA and silk protein enhances antimicrobial efficacy, making it a promising biomaterial for use as a medicament in endodontic procedures.
