Objective: To review the phenomenon of postmortem pink teeth, exploring its etiology, correlation with the cause of death, and the potential forensic significance of this medico-legal finding.
Methods: A comprehensive literature search was conducted using databases such as PubMed, Scopus, and B-on, employing keywords like "Forensic Pathology," "Forensic Dentistry," "Pink Teeth," and "Medico-legal aspects." The search included studies without temporal limits to gather extensive data on the postmortem pink teeth phenomenon.
Results: The postmortem pink teeth phenomenon is characterized by a red-pink discoloration of the dentin, typically sparing the enamel. It is most often observed in moist environments and cases involving water immersion, strangulation, and carbon monoxide poisoning. The study found no consistent relationship between the pink discoloration and specific causes of death, suggesting the phenomenon is more closely related to environmental conditions and the state of decomposition. The pink coloration is more prevalent in anterior, single-rooted teeth and younger individuals.
Conclusion: The postmortem pink teeth phenomenon remains a complex and enigmatic finding in forensic science. While it does not conclusively indicate a specific cause of death, understanding its occurrence can aid forensic investigations. Further research is needed to elucidate this phenomenon's mechanisms and validate its forensic relevance.

In August 2021, a female pink salmon displaying pale gills and abnormal behaviour was captured in River Lakselva in Northern Norway and later submitted to the Norwegian Veterinary Institute (NVI) for post-mortem examination. Histological examination of organ samples revealed structures indicative of systemic ichthyophoniasis, caused by Ichthyophonus sp.

Cardiac amyloidosis can be grouped into two main categories: immunoglobulin light chain (AL) and transthyretin (hATTR or hereditary and ATTRwt or wild type). Cardiac infiltration of misfolded proteins can lead to significant infiltrative processes and subsequent heart failure. Diagnosis of ATTRwt heavily relies on clinical suspicion, as it typically appears later in life and is limited to the heart.

From the Department of Pathology and Laboratory Medicine, University of Wisconsin School of Medicine and Public Health, Madison, WI.
Titanium dioxide is a versatile compound that is found in a variety of consumer products, medical hardware, and pharmaceuticals. Although oral and topical ingestion of this compound is common, intravenous introduction is much less common. We present three cases where significant titanium dioxide deposits were identified in liver and splenic tissue of three decedents, all of whom died of illicit drug overdose in the same geographic area and had fentanyl and its metabolites in blood on postmortem toxicologic testing.
