Cognitive-level analysis of dentomaxillofacial radiology questions in the Turkish dentistry specialization examination: a Bloom's revised taxonomy analysis.
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
backgroundBloom's revised taxonomy is widely used to evaluate the cognitive level of examination questions. With the growing use of large language models (LLMs), interest has increased in their potential to support cognitive classification. However, evidence comparing LLM-based classification with expert consensus in dental specialty examinations remains limited. This study aimed to analyze the cognitive levels of dentomaxillofacial radiology (DMFR) questions in the Turkish Dentistry Specialization Examination (DUS) and to evaluate the agreement between expert consensus and ChatGPT v5.2.
methodsA total of 130 text-based DMFR questions from the DUS were classified according to Bloom's revised taxonomy using expert consensus and ChatGPT v5.2. Agreement between classifications was assessed using exact agreement and quadratic-weighted Cohen's kappa.
results"Analyze" was the most frequent cognitive level in both expert consensus (41.5%) and ChatGPT classification (44.6%), followed by "Remember." Exact agreement between ChatGPT and expert consensus was 80.0%, with almost perfect ordinal agreement (κw = 0.851; 95% bootstrap CI: 0.769-0.923).
conclusionsChatGPT v5.2 showed high agreement with expert consensus for Bloom-level classification in this dataset. These findings suggest that LLM-based classification may support Bloom-level mapping as an assistive tool; however, they should be interpreted as preliminary evidence of feasibility rather than practical validation. Expert oversight remains necessary, and further research is needed to assess performance across different models, settings, and educational contexts.
