Assessment of calcium ion loss and its effect on microhardness of root canal dentin using 1% phytic acid and 17% EDTA: An

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: Irrigation is an essential component of successful endodontics. Various chemical irrigants have been assessed for their efficacy. Newer alternatives are being currently investigated to overcome the shortcomings of the currently used irrigants. Aims: The aim of the study was to compare the effectiveness of phytic acid in calcium ion removal and its effect on the microhardness of the root canal dentin during endodontic procedure. Subjects and Methods: This was an in vitro study conducted on 45 recently extracted single-rooted human mandibular premolars. They were decoronated and sectioned. One half of the tooth was used to evaluate calcium ion loss, while the other half was used to analyze microhardness. Statistical Analysis: The data were analyzed using analysis of variance and Tukey's post hoc analysis was used. P <0.001 was considered significant. Results: There was a less significant decrease in calcium level of root dentin after treatment with phytic acid as compared with ethylenediaminetetraacetic acid (EDTA). There was no significant difference between phytic acid and EDTA in relation to calcium ion loss and microhardness with their respective control group. Conclusion: 1% Phytic acid is a suitable irrigating solution compared to 17% EDTA, due to its less demineralizing effect on radicular dentin.
