Multiple pulp stones and shortened roots of unknown etiology.
[dentin dysplasia]
An
unusual
case
of
generalised
pulpal
calcifications
(
pulp
stones
)
with
normal
clinical
crowns
is
reported
in
a
13
-
year
-old
boy
.
Radiographic
examination
revealed
pulp
stones
in
the
single
rooted
and
premolar
teeth
,
situated
at
the
midroot
level
,
with
the
roots
bulging
around
them
.
The
apical
portion
of
the
roots
,
periodontal
ligament
space
,
and
surrounding
bone
had
a
normal
radiographic
appearance
,
apart
from
the
upper
premolars
,
and
no
periapical
pathology
was
discernible
.
The
upper
premolars
exhibited
considerably
shortened
roots
.
No
medical
,
dental
,
or
family
history
was
found
to
be
contributory
.
Reviewing
the
literature
revealed
similar
cases
,
but
with
differing
diagnoses
including
dentine
dysplasia
(
DD
)
or
idiopathic
cases
.
This
report
suggests
either
a
variation
of
DD
or
possibly
a
new
nonsyndromic
dentine
defect
,
and
highlights
the
difficulties
in
establishing
a
definitive
diagnosis
by
traditional
methods
.
The
recent
discovery
that
mutation
of
the
bicistronic
dentine
sialophosphoprotein
gene
(
DSPP
)
is
involved
in
DD
may
provide
solutions
to
this
problem
.
