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

Background/purpose: A newly developed sonic device for root canal irrigation, the SmartLite Pro EndoActivator, features modified vibration frequencies and behaviors. This study aimed to examine the cleaning efficacy and periapical pressure generation of sonically-activated irrigation (SAI) with different number of vertical strokes. Materials and methods: Seventy-two human anterior teeth were instrumented to a #25/0.07 taper. Experiment 1: 36 teeth were irrigated using: (1) EndoActivator (SAI-1), (2) SmartLitePro EndoActivator (SAI-2), and (3) syringe irrigation (SI) (n = 12, each). Experiment 2: 36 teeth were irrigated with SAI-2, varying the number of vertical strokes applied (0, 10, and 40 times; n = 12, each). Debris and smear layer scores were assessed using scanning electron microscopy. Experiment 3: Periapical pressures were measured during irrigation of plastic root canal models (#40/0.06 taper) with SAI-2 using 0, 10, or 40 strokes. Data were analyzed with the Kruskal Wallis and Mann-Whitney U tests ( Results: In Experiment 1, the SAI-2 group showed significantly better smear layer scores than the SAI-1 and SI groups ( Conclusion: The SmartLite Pro EndoActivator outperformed EndoActivator and syringe irrigation regarding cleaning efficacy. Increasing the number of vertical strokes improved the cleaning efficacy but also resulted in higher apical pressures.
