Extraction Of Diatoms From Teeth

Abstract

Diatoms, ubiquitous microalgae in aquatic environments, have long held forensic importance, particularly in diagnosing drowning cases. Conventionally, diatom analysis is performed on organs like lungs, liver, and bone marrow. This study explores an innovative, non-invasive method for extracting diatoms from dental surfaces, specifically the enamel, with the aim of determining time since submersion. Using extracted teeth submerged in water samples from different regions and analyzing diatom growth over 30 days, the study demonstrates a reliable correlation between diatom length and submersion duration. This technique not only conserves evidence but also provides rapid, accurate results crucial for forensic investigations.
