CAT scan reveals 'first form' of dental disease
(ANSA)
- Rome - The famed prehistoric man known as the Iceman had bad teeth,
according to the first CAT scan on the dental health of the
5,300-year-old frozen mummy kept in the northern Italian city of
Bolzano.
The
Iceman, also known as Oetzi because of the Oetz Alpine Valley where
he was found in a glacier by a German hiking couple in 1991, "had
tooth decay, deep dental abrasions, and a dead front tooth that was
probably caused by an accident or blow," said a team led by
Frank Ruhli of Zurich's Centre for Evolutionary Medicine.
The
Swiss scientists made 3-D reconstructions of the mummy's oral cavity
which showed that Oetzi "also suffered from strong infection of
the paradental tissue, which determined a lack of attachment of the
teeth to the gum, especially the molars,", Ruhli's team said.
One of the team leaders, Roger Seiler, said the Iceman had allowed
them to study the "first form of this disease up close,"
even though it has also been found in Stone Age skulls and Egyptian
mummies.
Contemporary
medicine has linked such periodontitis, or denegeneration of the bone
and gum, to cardiovascular disease," signs of which have already
been found in the Iceman.
"It's
interesting that the Iceman should also show hardening of the
arteries," said Albert Zink, head of the Institute for Mummies
and the Iceman at Bolzano's Eurac academy who coordinates global
studies on the ancient man.
"As
in the case of periodontitis, the cause is to be sought primarily in
his genetic predisposition," Fink said.
Eurac
linked Oetzi's tooth problems to his starch-laden diet of bread and
cereals which were "the mainstays of what people first ate after
the advent of agriculture".
Officials
at the South Tyrol Archaeological Museum, where the Copper Age hunter
is kept in a refrigerated cell, are planning to expand the venue to
cope with an ever-increasing flow of visitors.
They
said earlier this month the venue might be merged with the nearby
civic museum in the capital of the Alto Adige (South Tyrol)
region.
Since
the archaeological museum was inaugurated on March 28, 1998, Oetzi
has attracted more than 3.5 million visitors.
In
other marks of his renown, he boasts more than 5.5 million Google
hits, an ice-cream flavour created in his name, and an iPad and
iPhone app.
Created
last month, the new app lets youngsters learn about the Iceman's life
and the stream of scientific discoveries made about him.
The
application aims to provide "fun ways to get to know Europe's
oldest natural human mummy", including games featuring his
well-known tattoos - rumoured to have been copied by Brad Pitt - and
"his extraordinary gear including his bow and arrow", said
Bolzano's Larixpress publishing house.
New
discoveries about the world's oldest 'wet' mummy are being made all
the time.
Last
May traces of blood were found on him, the oldest blood sample ever
found.
A
year ago the first complete DNA map of the ancient man found that he
was lactose intolerant, or unable to digest a sugar in milk.
The
study also showed Oetzi had a predisposition towards heart disease, a
finding corroborated by the thickened arteries in the body.
The
mapping said the Iceman probably suffered from Lyme Disease, a
tick-borne infection whose symptoms may include fever, headache,
fatigue, depression, and a characteristic circular skin
rash.
According
to an international team, the rugged mountain man also shared a
common ancestor with the inhabitants of today's Sardinia and Corsica
and his blood group was O.
As
well as spurring countless studies and Internet items, the Iceman
draws more and more visitors to his Bolzano home.
He
had an anniversary bash there in September 2011 when the
purpose-built museum celebrated 20 years since two German tourists
spotted him peeping out of the glacier.
"Oetzi
has been great for us, the city and tourism in the entire region,"
Archaeology Museum Director Angelika Fleckinger said as the mummy,
2,000 years older than Tutankhamen, 'welcomed' kids to play with
prehistoric weapons and offered 'neolithic' food for
visitors.
Fleckinger
said the anniversary celebrations had a "special resonance"
for her.
"Sometimes
I think it is so strange. He died 5,000 years ago yet this person,
this Iceman, has become an important part of my life".
Forensic
science has made great strides since the Iceman was found on
September 19, 1991.
"We
know so much about him, that he had brown eyes and a few diseases,
was getting on a bit at 46, and died from an arrow wound.
"But
we will maybe never know what really happened in the last hours and
minutes of his life".
The
Iceman may still be something of a mystery but his generosity to his
adoptive home town is no secret.
According
to the most recent figures, the refrigerated man earns a total of
four million euros each year for restaurants, hotels and
souvenir-sellers, Fleckinger said.
Year
round, except for Christmas Day, New Year's Day and May Day, he also
raises 3.5 million euros in ticket fees at the restructured bank that
houses him.
That
means he pays about half of the Bolzano Archaeological Museum's
costs, drawing in over one thousand people a day.
This
compares to the average of 15% which other Italian museums defray out
of visitors' pockets.
The
Iceman's status as a global star is reflected by the 26 documentaries
made about him by the world's TV companies.
He
is perhaps the world's most famous mummy outside Egypt.
The
body, which dates back to 3000 BC, has spawned a global cottage
industry of studies.
As
well as discoveries about what he ate and what illnesses he suffered
from, there has been a keen debate on how he died from the arrow
wound found in his body - initially, it was thought, in a fight with
rival hunters.
One
theory says he was assassinated in a tribal power struggle.
Another
suggested he was the victim of ritual sacrifice.
Another
study - fiercely contested by patriotic residents of the formerly
Austrian region who see Oetzi as their proud forefather - reckons he
was cast out from his community because a low sperm count rendered
him childless.
An
eerie aura has also grown around the Iceman because of the allegedly
mysterious deaths of seven people who came into contact with him soon
after he was found.
