Today, the application of artificial intelligence has made it possible to automate work processes, increase the accuracy, speed and efficiency of solving the issues of forensic dentistry, and improve the quality of forensic evidence provided. At the same time, like any technology, artificial intelligence is not without some disadvantages of practical application. In this regard, the opinion is expressed that it is advisable to use artificial intelligence systems only as an auxiliary tool, leaving the primary role in making final decisions to forensic medical examiners.
