In the field of DNA testing, teeth play a vital role as an important sample for long-term preservation of DNA. Especially in the public security and judicial system, dental DNA testing has become an important means to identify criminal suspects and confirm the identity of the victim. However, the tooth's hard outer layer surrounds the pulp tissue, making it difficult to directly extract DNA.Tooth crusher, as a device specially designed for crushing tooth samples, uses a specific crushing mechanism to quickly and evenly crush tooth samples into powder, thereby facilitating subsequent DNA extraction and analysis. Compared to traditional manual tapping or grinding methods, tooth crushers have significant advantages. It not only improves fragmentation efficiency and reduces sample processing time, but also ensures uniformity of fragmentation and provides high-quality samples for subsequent DNA extraction.The working principle of a tooth crusher usually involves the interaction of the movable knife and the fixed knife. In the crushing chamber, the high-speed rotating movable knife and the fixed fixed knife quickly crush the input tooth samples through cutting, impact, extrusion, etc. The crushed samples are screened through the screen and fall into the collection box to complete the crushing process. This process is not only efficient, but also safe, avoiding sample contamination or damage that may occur with traditional methods.In the pre-processing process of laboratory tooth DNA testing, the application of tooth crusher is particularly important. First, the preprocessing of tooth samples is crucial for subsequent DNA extraction. With a tooth crusher, the tooth sample can be quickly broken into powder, thereby exposing the DNA in the dental pulp tissue. This process not only simplifies the sample processing steps, but also improves the success rate of DNA extraction.Secondly, the use of tooth crusher can ensure the uniformity of the sample. In DNA testing, the uniformity of the sample has an important impact on the accuracy of the results. The tooth crusher ensures that each tooth sample is crushed evenly through a precise crushing mechanism, thereby avoiding detection errors caused by uneven samples.In addition, tooth crusher also has the advantages of simple operation and easy maintenance. Laboratory personnel only need to put the tooth sample into the crusher, set the parameters, and start the crushing process. After the crushing is completed, simple cleaning and maintenance can keep the equipment in good condition and ensure the smooth progress of subsequent experiments.In the public security and judicial system, the application of tooth crusher provides strong support for the detection of cases. By quickly and accurately crushing tooth samples, high-quality DNA information is extracted, providing a scientific basis for identifying criminal suspects and confirming the identity of the victim. At the same time, the use of tooth crusher also improves detection efficiency, shortens case detection time, and makes positive contributions to social harmony and stability.In summary, tooth crusher, as an efficient and accurate tool for laboratory dental DNA detection pre-processing, has significant advantages and broad application prospects. It not only improves crushing efficiency and ensures sample uniformity, but also simplifies operating steps and is easy to maintain. In the public security and judicial system, the application of tooth crusher provides strong support for the detection of cases.
