Role of dermatoglyphics as an indicator of precancerous and cancerous lesions of the oral cavity.
[oral submucous fibrosis]
Oral
squamous
cell
carcinoma
(
SCC
)
is
one
name
that
causes
panic
and
holds
an
undeserved
high
ranking
as
a
killer
.
Another
important
condition
which
has
become
a
major
public
health
issue
in
South
East
Asia
is
oral
submucous
fibrosis
(
OSF
)
.
Not
all
the
people
using
tobacco
suffer
from
these
diseases
.
Genetic
predisposition
might
explain
such
an
individual
variability
that
can
be
predicted
by
using
various
cytogenetic
markers
.
However
,
these
studies
are
far
more
costly
and
complicated
.
So
,
dermatoglyphics
may
be
of
immense
clinical
significance
to
segregate
those
individuals
who
are
at
an
increased
risk
for
developing
these
diseases
.
The
present
study
was
conducted
to
analyze
the
palmar
dermatoglyphics
in
SCC
and
OSF
and
find
a
dermatoglyphic
marker
,
if
any
.
Cross
sectional
study
.
120
individuals
were
divided
into
four
groups
based
upon
their
habits
of
tobacco
/
areca
nut
usage
and
presence
of
OSF
/
SCC
.
Dermatoglyphic
patterns
were
recorded
using
standard
ink
method
.
Various
patterns
were
analysed
statistically
in
the
four
groups
.
In
SCC
,
there
was
an
increase
in
frequency
of
arch
and
ulnar
loop
patterns
on
fingertips
,
decrease
in
frequency
of
simple
whorl
patterns
on
fingertips
,
decrease
in
frequency
of
palmar
accessory
triradii
on
right
and
left
hands
.
Significant
findings
in
OSF
included
an
increase
in
frequency
of
arch
and
ulnar
loop
pattern
,
decrease
in
frequency
of
simple
whorl
patterns
on
fingertips
,
decrease
in
atd
angle
on
right
hand
,
decrease
in
frequency
of
palmar
accessory
triradii
on
right
hand
.
The
results
revealed
that
the
field
of
dermatoglyphics
holds
promising
results
for
determining
the
genetic
susceptibility
of
individuals
to
develop
SCC
and
OSF
.
