By means of text messages, ChatGPT establishes a dialog with users to provide informational content and create texts within a wide array of styles. Technically, ChatGPT could be used for scientific writing; however, it is important to reflect upon what makes a manuscript in fact scientific. Is it just a matter of style or, much more than that, is it all the scientific background supporting a clear research question, sound methodological design, irrefutable results, and an evidence-based conclusion? Despite the constant repository feeding through machine learning, the startup OpenAI (San Francisco, CA, USA) responsible for creating ChatGPT has pointed out that even with this vast amount of information, some limitations may compromise its performance, such as the risk of providing incorrect information, producing harmful instructions, and inducing bias. Furthermore, despite its ability to respond to several languages, better results are reported when searching in English. The possibility of humans being replaced with AI seems to be a major concern in the minds of contemporary professionals. Although ChatGPT presents itself as a revolutionary tool capable of mimicking human writing, questions regarding its application in academic scenarios remain unclear. It is important to highlight that the literature on the ethical aspects of using ChatGPT is still scarce; nonetheless, a recent study showed that students are already using it for scientific writing. Therefore, there is an urgent need to discuss and understand the applications and possible developments of ChatGPT in the academic context. It is also necessary to reflect on its ethical limitations to include it more appropriately in daily educational life. Although previous literature may not have specifically studied the application of ChatGPT to tasks associated with dental radiology, the emergence of ChatGPT has brought both excitement and caution. While it seems to have the potential to comprehensively collect, organize, and provide knowledge related to image-based diagnosis, we should not neglect professional judgment and critical thinking, especially when it comes to diagnostic accuracy. Concerns related to language inaccuracy, patient privacy, and data security should also be highlighted when using this tool to communicate sensitive medical information. Therefore, it is essential to have an ongoing and open discussion about the applications and advancements of this new AI language model in oral radiology. There is also a need for further research and development to ensure that ChatGPT can be integrated effectively into the workflows of oral radiologists and dentists.
