Maturation of teeth adjacent to dental agenesis site.
[]
The
purpose
of
this
study
was
to
evaluate
the
developmental
stage
of
teeth
adjacent
to
the
agenesis
site
in
comparison
to
their
antimeres
.
Panoramic
views
of
39
patients
with
unilateral
dental
agenesis
and
42
normal
controls
were
evaluated
.
The
dental
developmental
stage
(
normal
or
delayed
)
of
the
teeth
adjacent
to
the
agenesis
site
was
determined
for
each
patient
using
the
Haavikko
's
method
,
while
the
overall
dental
age
was
determined
by
Becker
's
method
.
No
statistically
significant
difference
was
found
in
the
developmental
stage
of
teeth
adjacent
to
the
agenesis
,
compared
to
their
antimere
and
to
the
same
teeth
in
the
normal
control
group
.
However
,
the
prevalence
of
cases
with
no
difference
in
development
was
almost
double
for
the
tooth
distal
to
the
agenesis
site
compared
to
the
tooth
mesial
to
the
agenesis
site
in
the
hypodontia
group
(
84
.
6
%
distal
and
43
.
6
%
mesial
;
p
<
0
.

)
and
in
the
control
group
(
83
.
3
%
distal
and
52
.
4
%
mesial
;
p
<
0
.
002
)
.
In
most
of
the
cases
the
tooth
distal
to
the
agenesis
site
was
the
1
st
permanent
molar
.
(

)
No
difference
was
found
between
the
developmental
stage
of
teeth
adjacent
to
the
agenesis
site
and
their
antimeres
.

Teeth
mesial
to
the
agenesis
site
showed
some
delay
in
development
compared
to
teeth
distal
to
the
agenesis
site
,
in
this
study
.

The
1
st
molars
,
which
were
in
most
of
the
cases
the
distal
adjacent
tooth
to
the
site
of
agenesis
,
showed
developmental
stability
.

Additional
longitudinal
studies
are
needed
to
examine
the
dental
developmental
pattern
in
patients
with
agenesis
.
