Feasibility of opportunistic dental diagnostics in routine photon-counting CT examinations of the cervical spine.
Article in BMC oral health, 2026. 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
backgroundThis study evaluates the potential of routine clinical photon-counting computed tomography (PCCT) of the cervical spine for opportunistic dental diagnostics.
methodsThirty-three patients undergoing routine PCCT were included in this study, with imaging performed at an average dose of 13 mGy. Images were reconstructed to a voxel size of 156 μm and a slice thickness of 0.4 mm. Quantitative image quality was assessed using the contrast-to-noise ratio (CNR) between dental structures, while qualitative assessment of structures like enamel, dentine, root canals, and cortical bone was conducted by two experienced readers using a five-point scale.
resultsThe inter-reader reproducibility and intra-class correlation coefficient were excellent (all > 0.947). CNRs ranged from 1.6 to 6.1 for all relevant contrasts, and qualitative scores were excellent for all dental structures. Dental pathologies were detected in a significant portion of patients: caries-induced decay in 9 patients (27%) at 26 sites, apical lesions in 12 patients (36%) at 26 sites, and alveolar bone loss in 12 patients (36%) at 12 sites. At least one pathology was present in 23 patients (70%).
conclusionsPCCT offers potential for opportunistic dental diagnostics, providing earlier detection of dental issues and potentially improving overall dental care outcomes.
