Over the last year and a half, dentists have reported an increase in tooth fractures, damaged fillings and jaw soreness among their patients. While it's too early to say for sure, some experts surmise that the stress of the pandemic has caused an uptick in the number of people who grind their teeth and clench their jaw – behaviours known as bruxism.

The raw material in used tire carcasses is reclaimed by cutting the tire into quarter segments and freezing the segments with liquid nitrogen in a controlled environment freezing chamber. Rotary air locks pass material to and from the chamber. Steel and fiber materials are removed in a stripping chamber where the frozen rubber both broken into smaller chunks.

Burns found that cryogenic grinding is effective with children's teeth, but more testing will need to be done before this protocol is implemented in the BCA. In order to test whether or not conclusive results could be taken from the extraction of DNA from badly burned teeth, Burns placed 39 human teeth inside pork fillets to simulate a human jaw.

Recovery of DNA from human teeth by cryogenic grinding J Forensic Sci. 1998 Nov;43(6):1199-202. Authors D Sweet 1, D Hildebrand.

DNA has been previously recovered from human teeth for RFLP and PCR-based forensic analysis. In some cases, the maximum amount of undisturbed tooth structure is required for ulterior forensic analysis. But, in most cases, following comprehensive documentation, it is possible to section the tooth longitudinally or horizontally, or crush it to access the DNA-rich core.

DNA was recovered from the teeth of the skeleton using cryogenic grinding. Comparison of the genotypes resulted in the conclusion that the DNA originated from the same source. The use of PAP smears in this way is seen as a valuable resource in cases where positive identification using traditional dental and medical records is not possible.

Briefly, the external root surfaces were cleaned with 3% hydrogen peroxide and disinfected with 2.5% sodium hypochlorite, which was then inactivated with 10% sodium thiosulfate.

Grinding teeth while sleeping or awake can lead to jaw- and tooth-related complications (i.e., TMJ disorder) and should be treated quickly before more harm occurs. There's no immediate "cure" for bruxism, but there are ways to get it under control and diminish its effects on your jaw and teeth.
