Comparative performance of ChatGPT, Gemini, and Deepseek on endodontic exam questions in Turkish and English.
Article in BMC oral health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundLarge language model-based artificial intelligence (LLM-based AI) applications have become a focal point in the healthcare field. This study aimed to compare the performance of ChatGPT-4, Gemini 2.0 and DeepSeek-R1 in answering endodontics questions from the dentistry specialty examination in both Turkish and English.
methodsA total of 130 multiple-choice Endodontics questions from the dentistry specialty examination question pool were presented to LLMs developed by OpenAI (ChatGPT-4), Google (Gemini 2.0) and DeepSeek (DeepSeek-R1). The questions were entered into each model under standardized conditions in both English and Turkish. The responses and their explanations were classified based on predefined criteria as “correct answer and explanation”, “correct answer with incorrect explanation” and “incorrect”. The R programming language was used within the RStudio environment for statistical analysis. McNemar’s Chi-squared test with continuity correction was applied to analyze the models’ performance in providing correct answers and explanations across different languages, as well as to compare performance between models. Fisher’s Exact Test was used to analyze the models’ responses to different question types. The threshold for statistical significance was set at p < 0.05.
resultsWhen analyzed individually, DeepSeek-R1, Gemini 2.0 and ChatGPT-4 provided correct answers at a higher rate in English compared to Turkish. In Turkish, the performance of DeepSeek-R1 and Gemini 2.0 in providing correct answers and accurate explanations was significantly higher than that of ChatGPT-4. All models demonstrated significantly better performance on Simple-style questions compared to Combination-style questions in both languages.
conclusionsThese findings indicate that LLMs show promise in standardized tests within dentistry. However, despite their ability to recognize patterns and organize data, they have limitations in fully understanding the underlying concepts of information. The results also highlight the need for continuous improvements to enhance their effectiveness across different subjects and languages, as well as the potential occurrence of hallucinations in their responses.
