Non syndromic oligodontia: case report.
[oligodontia]
Oligodontia
is
a
rare
genetic
disorder
which
represents
the
congenital
absence
of
more
than
six
teeth
in
primary
,
permanent
or
both
dentitions
.
It
is
usually
a
part
of
a
syndrome
and
seldom
occurs
as
an
isolated
entity
.
Genes
responsible
for
non
syndromic
oligodontia
are
found
to
be
MSX
1
and
PAX
9
genes
.
In
this
case
report
a
13
year
old
boy
is
presented
who
had
absence
of
all
four
second
permanent
molars
and
permanent
mandibular
incisors
.
The
maxillary
central
incisors
presented
with
conical
shape
.
During
physical
examination
,
there
was
no
abnormality
in
either
hairs
or
nails
,
perspiration
was
normal
and
no
congenital
clefts
of
lip
or
palate
was
seen
.
Hence
in
this
case
,
Oligodontia
is
not
associated
with
any
syndrome
which
is
a
rare
finding
.
