Inventions often arise when challenges obstruct the path to truth. In this regard, the contemporary role of forensic science in identifying deceased individuals is crucial, and the contribution of forensic odontology is particularly significant. Investigators have long recognized the potential of human teeth as a source of forensically significant DNA evidence. However, accessing this DNA has posed challenges, as earlier methods such as crushing teeth or analyzing neurovascular tissues were prone to contamination or other drawbacks. Recently, various authorities have researched an alternative method to maximize DNA recovery: "cryogenic grinding." This technique is simple, relatively rapid, and overcomes the drawbacks associated with previous methods. In this article, we provide insight into the unique and critical role of cryogenic grinding in analyzing DNA recovery from human teeth.
