The recent and surprising discovery that the human
microbiome is highly personalized opens new possibilities in
the development of novel forensic approaches. Interestingly,
recent studies showed that the oral microbiome presents
consistent intra-individual stability and similarity over time
and, equally important, consistent inter-individual variability.
Regarding child abuse, bite marks are frequently found. In
this context, the American Board of Forensic Odontology
recommends that the bite mark is considered not only a
physical evidence, where the bite mark analysis is used for
comparison between bite marks on a bitten object and the
suspects’ teeth, but also a biological evidence, where the
bite injury should be swabbed for DNA presence, to compare
it with the possible perpetrator. These DNA can be human
or microbial, in the specific case of bite marks from oral
microbiome. Recent research indicates that this procedure
should also be carried out in non-human substract, as some
researchers stated that it is possible to recover and isolate
human nuclear and mitochondrial DNA and also oral human
microbiome DNA from bitten foods. Although human DNA
has a great discriminatory power, is difficult to recover due
to its low quantity and frailty. So, oral microbiome represents
an innovative alternative for perpetrator identification in
a context of crimes involving bite marks. The aim of this
work is to explore the possibility of using the microbiome in
bite marks inflicted in child abuse for human identification
purposes.
