The presence of the maxillary lateral incisor in the cleft gap in patients with unilateral cleft lip and palate. Preliminary report.
[]
Evaluation
of
the
presence
of
the
maxillary
lateral
incisor
in
the
cleft
in
patients
with
complete
unilateral
cleft
lip
and
palate
treated
with
the
use
of
various
surgical
protocols
.
A
retrospective
analysis
was
conducted
as
regards
diagnostic
models
,
panoramic
radiographs
and
tooth
images
of
the
cleft
of
75
patients
with
complete
unilateral
cleft
lip
and
palate
treated
with
the
use
of
various
surgical
protocols
(
group
I
:
patients
who
underwent
one
-
stage
surgery
with
early
alveolar
bone
grafting
;
group
II
:
one
-
stage
operation
with
secondary
alveolar
bone
grafting
;
group
III
:
two
-
stage
operation
with
secondary
bone
graft
or
no
graft
)
.
The
analysis
of
the
relation
between
the
applied
surgical
protocol
and
the
absence
of
the
maxillary
lateral
incisor
indicated
the
lack
of
the
lateral
incisor
in
the
cleft
in
4
patients
from
group
I
(
16
%
)
,
8
patients
from
group
II
(
32
%
)
and
13
patients
from
group
III
(
52
%
)
.
The
difference
between
groups
I
and
III
was
statistically
significant
(
p
=
0
.
007
)
.
The
analysis
also
revealed
that
as
regards
the
lack
of
the
incisor
on
the
side
of
the
cleft
(
in
all
three
groups
)
,
the
hypodontia
of
the
maxillary
lateral
incisor
on
the
left
side
was
twice
as
rare
as
on
the
right
side
,
in
14
patients
(
25
%
)
on
the
left
side
and
in
11
patients
(
58
%
)
on
the
right
side
respectively
(
p
=
0
.
009
)
.
The
analysis
of
the
relation
between
the
absence
of
the
lateral
incisor
and
the
side
of
the
cleft
in
particular
groups
of
patients
indicated
that
the
relation
was
statistically
significant
only
in
group
III
.
T
he
studies
reveal
that
the
type
of
surgical
procedure
may
affect
the
presence
or
lack
of
the
lateral
incisor
in
the
maxilla
on
the
cleft
side
.
However
,
it
is
necessary
to
conduct
studies
on
larger
material
.
