1 · What the graph read from it

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.

2 · The registry

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

Context: Guided endodontics has been revolutionizing endodontics, emphasizing the need to further investigate its capabilities in terms of degrading separated instruments will be of great value. Aims: The aim of this study was to compare, in vitro, the static endodontic guide and ultrasonic methods for managing separated instruments, focusing on fracture resistance, dentin changes, and procedural time. Materials and Methods: Twenty-two extracted double-rooted maxillary first premolars were decoronated to 15 mm in length and mounted in acrylic resin blocks for standardized cone-beam computed tomography (CBCT) scanning. Size 25/0.06 rotary files were notched at 3 mm and separated in the coronal third of the buccal canals under controlled conditions. Teeth were randomly assigned into two groups ( Statistical Analysis: Normality tested; t-test for parametric, Mann-Whitney for nonparametric. Results: The ultrasonic group showed significantly higher fracture resistance and less root canal volume increase compared to the static endodontic guide group. However, the ultrasonic group required significantly more time for retrieval. All differences were statistically significant ( Conclusions: The study compares ultrasonic and static endodontic guides for instrument retrieval, highlighting static endodontic guides' speeds but increased dentin loss, deeming them unsuitable for degrading instruments with burs. Further research is needed.
