A Nanocomposite Shield Constructed for Protection Against the Harmful Effects of Dental X-Rays.
Article in Journal of dentistry (Tehran, Iran), 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectivesThis study aimed to compare a number of new nano-composites capable of protecting the jaw from ionizing radiation. MATERIALS AND
methodsFour different types of nano-powders [Ti, Zr (IV) oxide, Ag and Co] were mixed in a polymer matrix to create nano-composites with doping values of 8% in weight. Small-angle X-ray scattering (SAXS) analysis was performed using a HECUSSAXS system with 50 kV- 50 mA. Co nano-composites (Co-pnm) yielded the most promising values of the four nanocomposites tested in terms of X-ray absorption. Thus, 4×2 cm Co-pnm samples of different thicknesses (0.20, 0.50, 0.57 and 0.60 cm) were prepared, and SAXS analysis was performed in order to assess the effects of material thickness on xray absorption. An experimental multi part shield was constructed from Co-pnm around tooth #36 to test the effect of nanomaterial on the image quality under X-ray beam.
resultsLogarithmic distributions of the transmitted intensity values (I) showed that 0.20 cm Co-pnm had the highest transmission value (16.05) followed by 0.50 cm Co-pnm (15.44), 0.57 cm Co-pnm (15.07) and 0.60 cm Co-pnm (15.06). The 0.2 cm Co-pnm had an effective radius of the nano-aggregation value (77.44 Å) lower than that of the other thicknesses (0.50, 0.57 and 0.60 cm) of Co-pnm, which had similar values ranging from 66.22 to 66.34 Å. The 0.50 cm Co-pnm had the lowest Dmax value of the different thicknesses of Co-pnm tested.
conclusionCo nanocomposite can be used as a protection shield for the harmful effects of dental X-ray.
