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

objectivesRoot canal filling is a fundamental step in non-surgical root canal treatment (RCT), required to prevent reinfection or new infection within the root canal system. Traditionally root canal filling uses a sealer in combination with gutta-percha (GP). Here, two cases are presented in which the root canals were filled using only a methacrylic resin-based sealer without GP. MATERIALS AND

methodsTwo patients (one male, one female) required RCT - one due to irreversible pulpitis and the other to facilitate a subsequent post-retained protheses. Each RCT was performed according to a standardized procedure, before root canal filling using only methacrylic resin sealer.

resultsFillings were completed in curved and straight root canals without evidence of apical extrusion. No clinical symptoms or signs of dissolution were observed during follow-up (24 and 12 months in the respective cases).

conclusionsOur findings demonstrate the potential applicability of this novel technique for root canal filling using only a methacrylic resin-based sealer without GP. CLINICAL RELEVANCE: The success of our RCT cases offers evidence to support further clinical studies that compare the outcomes with standard root canal procedures.
