Delayed Diagnosis of an Aspirated Dental Crown Presenting as Chronic Bronchitis and Pneumonia in an Adult Male: A Case Report.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Foreign body aspiration is uncommon in adults compared to children. The aspiration of dental materials is a relatively rare event, whether it occurs during, or independently of, dental procedures. Its true incidence remains difficult to assess due to variations across reported studies. Such aspirations can lead to both immediate and delayed complications, including pneumonia, which may result in local or systemic consequences. We report a rare case of an unnoticed aspiration of a dental crown, discovered several months after inhalation. A 44-year-old male with a history of chronic tobacco use presented with chronic cough, recurrent episodes of bronchitis, and general health deterioration. Chest X-ray (frontal and lateral views) and thoracic computed tomography (CT) guided the diagnosis, which was subsequently confirmed via flexible bronchoscopy. Interestingly, the dental crown was spontaneously expectorated by the patient a few hours after the bronchoscopy. Follow-up imaging revealed persistent, irreversible parenchymal destruction, despite clinical improvement and resolution of recurrent bronchitis. From a theoretical standpoint, and according to the literature, rigid bronchoscopy remains the gold standard for the removal of aspirated dental materials. This case underscores the importance of considering foreign body aspiration in the differential diagnosis of recurrent respiratory infections and chronic bronchitis. It also highlights the value of standard chest imaging in the initial assessment, as well as the utility of flexible bronchoscopy outside of the acute setting.
