Researchers in Brazil have developed an AI system that can determine an individual's sex with 96% accuracy using panoramic radiographs, wide-view dental X-ray images. The system's accuracy is higher for individuals over 16 years old and with good picture resolution. The study, published in the Journal of Forensic Sciences, collected over 200,000 panoramic radiographs to train machine-learning algorithms for sex estimation. The algorithms, a convolutional neural network and a residual network, showed similar accuracy levels. Factors affecting accuracy include image resolution and age, with the system performing best for patients between 20 and 50 years old. The study highlights the potential of AI in forensic dentistry for sex determination, emphasizing the importance of image quality, age, and sex in algorithm performance. However, the effectiveness of the tool may vary when applied to images from deceased individuals with advanced decomposition.
