Arterial cerebral air embolism occurred during root canal treatment: a case report and literature review.
Article in Asian biomedicine : research, reviews and news, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: Root canal treatment is generally safe, but cerebral arterial air embolism (CAAE) is a rare, life-threatening complication. Case presentation: A 69-year-old male with apical periodontitis of teeth #31 and #41 suffered sudden loss of consciousness and coma during endodontic treatment. Cerebral computed tomography (CT) revealed multiple intracranial punctate gas densities with cervical and maxillofacial subcutaneous emphysema. Hyperbaric oxygen therapy (HBOT) led to complete neurological recovery. Conclusion: Clinicians must recognise the risk of arterial air embolism from high-pressure air syringes. Prevention hinges on minimising air pressure and duration, using the lowest effective pressure, and ensuring meticulous haemostasis. Acute neurological deterioration demands immediate imaging and urgent HBOT. Integrating these measures into dental safety standards is essential.
